+# Zone Documentation
+
+The `zone` of the order is an optional secondary account attached to the order with two additional privileges:
+
+1. The zone may cancel orders where it is named as the zone by calling `cancel`. (Note that offerers can also cancel their own orders, either individually or for all orders signed with their current nonce at once by calling `incrementNonce`).
+2. "Restricted" orders (as specified by the order type) must either be executed by the zone or the offerer, or must be approved as indicated by a call to an `isValidOrder` or `isValidOrderIncludingExtraData` view function on the zone.
+
+An example zone contract implementation can be found at `/contracts/zones/GlobalPausable.sol`
+
+The `GlobalPausable` contract can be used by its deployer to cancel specific orders, execute fulfillment on restricted order, and pause all orders which use it as a zone.
+
+## Ideas
+
+Zones are a powerful addition to the idea of simple marketplaces. By adding additional logic to approve / reject Seaport orders, many new applications are possible. Zones could potentially be used by new marketplaces built on top of Seaport to:
+
+- Stop sales of stolen assets
+- Limit the number of NFTs from a particular collection that can be sold in a given amount of time
+- Enforce a particular floor or ceiling price for certain assets
+- Make other arbitrary calls to outside price oracles
+- Track extra incentives for users completing valid orders
+
+...and probably more that we haven't even thought of yet!
+
+We encourage anyone in the world to build and deploy your own unique zones and help decentralize Seaport as a platform.

+
+We could use something like this, to allow the owner of the zone to execute restricted orders, but its not entirely necessary

 ## Ideas
 
 Zones are a powerful addition to the idea of simple marketplaces. By adding additional logic to approve / reject Seaport orders, many new applications are possible. Zones could potentially be used by new marketplaces built on top of Seaport to:

 The `zone` of the order is an optional secondary account attached to the order with two additional privileges:
 
-1. The zone may cancel orders where it is named as the zone by calling `cancel`. (Note that offerers can also cancel their own orders, either individually or for all orders signed with their current nonce at once by calling `incrementNonce`).
+1. The zone may cancel orders where it is named as the zone by calling `cancel`. (Note that offerers can also cancel their own orders, either individually or for all orders signed with their current counter at once by calling `incrementCounter`).
 2. "Restricted" orders (as specified by the order type) must either be executed by the zone or the offerer, or must be approved as indicated by a call to an `isValidOrder` or `isValidOrderIncludingExtraData` view function on the zone.
 
 An example zone contract implementation can be found at `/contracts/zones/GlobalPausable.sol`

 1. The zone may cancel orders where it is named as the zone by calling `cancel`. (Note that offerers can also cancel their own orders, either individually or for all orders signed with their current counter at once by calling `incrementCounter`).
 2. "Restricted" orders (as specified by the order type) must either be executed by the zone or the offerer, or must be approved as indicated by a call to an `isValidOrder` or `isValidOrderIncludingExtraData` view function on the zone.

+An example zone contract implementation can be found at `/contracts/zones/PausableZone.sol`.
 
-The `GlobalPausable` contract can be used by its deployer to cancel specific orders, execute fulfillment on restricted order, and pause all orders which use it as a zone.
-
-## Further implementation
-
-We could use something like this, to allow the owner of the zone to execute restricted orders, but it's not entirely necessary:
-
-```solidity
-function executeRestrictedOrderZone(
-    address _globalPausableAddress,
-    address _seaportAddress,
-    OrderComponents[] calldata orders
-) external {
-    require(msg.sender == deployerOwner, "Only the owner can execute orders with the zone.");
-
-    GlobalPausable gp = GlobalPausable(_globalPausableAddress);
-    gp.executeRestrictedOffer(_seaportAddress, orders);
-}
-```
+The `PausableZone` contract can be used by its controller to cancel orders, execute fulfillment on restricted order, and pause all orders which use it as a zone.
 
 ## Ideas
 
 Zones are a powerful addition to the idea of simple marketplaces. By adding additional logic to approve / reject Seaport orders, many new applications are possible. Zones could potentially be used by new marketplaces built on top of Seaport to:
 
 - Stop sales of stolen assets
+- Pause orders in case of emergency without invalidating users' approvals
 - Limit the number of NFTs from a particular collection that can be sold in a given amount of time
 - Enforce a particular floor or ceiling price for certain assets
 - Make other arbitrary calls to outside price oracles
 - Track extra incentives for users completing valid orders
+- And more.
 
-...and probably more that we haven't even thought of yet!
-
-We encourage anyone in the world to build and deploy your own unique zones and help decentralize Seaport as a platform.
+Anyone in the world can build and deploy their own unique zones and help decentralize Seaport as a platform.

+# Deloying Seaport
+
+The official Seaport 1.1 address will always be `0x00000000006c3852cbEf3e08E8dF289169EdE581` on all EVM chains; likewise the official ConduitController address will always be `0x00000000F9490004C11Cef243f5400493c00Ad63`. In order to deploy these to the same address on any chain, a specific series of steps must be followed.
+
+If there is no `IMMUTABLE_CREATE2_FACTORY_ADDRESS` on the chain, you must deploy this first.
+
+1. Send 0.01 Ether to the `KEYLESS_CREATE2_DEPLOYER_ADDRESS` (`0x4c8D290a1B368ac4728d83a9e8321fC3af2b39b1`)
+2. Create the `KEYLESS_CREATE2_ADDRESS` contract at `0x7A0D94F55792C434d74a40883C6ed8545E406D12` by submitting this pre-signed transaction: `0xf87e8085174876e800830186a08080ad601f80600e600039806000f350fe60003681823780368234f58015156014578182fd5b80825250506014600cf31ba02222222222222222222222222222222222222222222222222222222222222222a02222222222222222222222222222222222222222222222222222222222222222`
+3. Create the `INEFFICIENT_IMMUTABLE_CREATE2_FACTORY_ADDRESS` contract at `0xcfA3A7637547094fF06246817a35B8333C315196` by submitting:

 # Deloying Seaport
 
-The official Seaport 1.1 address will always be `0x00000000006c3852cbEf3e08E8dF289169EdE581` on all EVM chains; likewise the official ConduitController address will always be `0x00000000F9490004C11Cef243f5400493c00Ad63`. In order to deploy these to the same address on any chain, a specific series of steps must be followed.
+Seaport and the ConduitController can be deployed to the same address on all EVM chains using the CREATE2 Factory.

 3. Validate deployments were successful by checking that `Seaport` is returned by `seth --to-ascii $(seth call 0x00000000006c3852cbEf3e08E8dF289169EdE581 'name()')`
+
+## Verifying Seaport and ConduitController
+After `Seaport` and `ConduitController` are deployed, you should verify them.
+
+1. Ensure that `EXPLORER_API_KEY` and `NETWORK_RPC` are set in `.env` appropriatly.
+2. Verify `ConduitController` by calling:
+
+```
+npx hardhat verify npx hardhat verify --network verificationNetwork "0x00000000F9490004C11Cef243f5400493c00Ad63"
+```
+
+3. Verify `Seaport` by calling:
+
+```
+npx hardhat verify npx hardhat verify --network verificationNetwork "0x00000000006c3852cbEf3e08E8dF289169EdE581" "0x00000000F9490004C11Cef243f5400493c00Ad63"

+## Verifying Seaport and ConduitController
+After `Seaport` and `ConduitController` are deployed, they are verified as follows:
+
+1. Ensure that `EXPLORER_API_KEY` and `NETWORK_RPC` are set in `.env` appropriatly.
+2. Verify `ConduitController` by calling:
+
+```
+npx hardhat verify --network verificationNetwork "0x00000000F9490004C11Cef243f5400493c00Ad63"
+```
+
+3. Verify `Seaport` by calling:

 ## Known Limitations and Workarounds
 
 - As all offer and consideration items are allocated against one another in memory, there are scenarios in which the actual received item amount will differ from the amount specified by the order — notably, this includes items with a fee-on-transfer mechanic. Orders that contain items of this nature (or, more broadly, items that have some post-fulfillment state that should be met) should leverage "restricted" order types and route the order fulfillment through a zone contract that performs the necessary checks after order fulfillment is completed.
-- As all offer items are taken directly from the offerer and all consideration items are given directly to the named recipient, there are scenarios where those accounts can increase the gas cost of order fulfillment or block orders from being fulfilled outright depending on the item being transferred. If the item in question is Ether or a similar native token, a recipient can throw in the payable fallback or even spend excess gas from the submitter. Similar mechanics can be leveraged by both offerers and receives if the item in question is a token with a transfer hook (like ERC1155 and ERC777) or a non-standard token implementation. Potential remediations to this category of issue include wrapping Ether as WETH as a fallback if the initial transfer fails and allowing submitters to specify the amount of gas that should be allocated as part of a given fulfillment. Orders that support explicit fulfillments can also elect to leave problematic or unwanted offer items unspent as long as all consideration items are received in full.

Orders that support explicit fulfillments can also elect to leave problematic or unwanted offer items unspent as long as all consideration items are received in full.
 - As fulfillments may be executed in whatever sequence the fulfiller specifies as long as the fulfillments are all executable, as restricted orders are validated via zones prior to execution, and as orders may be combined with other orders or have additional consideration items supplied, any items with modifiable state are at risk of having that state modified during execution if a payable Ether recipient or onReceived 1155 transfer hook is able to modify that state. By way of example, imagine an offerer offers WETH and requires some ERC721 item as consideration, where the ERC721 should have some additional property like not having been used to mint some other ERC721 item. Then, even if the offerer enforces that the ERC721 have that property via a restricted order that checks for the property, a malicious fulfiller could include a second order (or even just an additional consideration item) that uses the ERC721 item being sold to mint before it is transferred to the offerer. One category of remediation for this problem is to use restricted orders that do not implement `isValidOrder` and actually require that order fulfillment is routed through them so that they can perform post-fulfillment validation. Another interesting solution to this problem that retains order composability is to "fight fire with fire" and have the offerer include a "validator" ERC1155 consideration item on orders that require additional assurances; this would be a contract that contains the ERC1155 interface but is not actually an 1155 token, and instead leverages the `onReceived` hook as a means to validate that the expected invariants were upheld, reverting the "transfer" if the check fails (so in the case of the example above, this hook would ensure that the offerer was the owner of the ERC721 item in question and that it had not yet been used to mint the other ERC721). The key limitation to this mechanic is the amount of data that can be supplied in-band via this route; only three arguments ("from", "identifier", and "amount") are available to utilize.
 - As all consideration items are supplied at the time of order creation, dynamic adjustment of recipients or amounts after creation (e.g. modifications to royalty payout info) is not supported. However, a zone can enforce that a given restricted order contains _new_ dynamically computed consideration items by deriving them and either supplying them manually or ensuring that they are present via `isValidZoneIncludingExtraData` since consideration items can be extended arbitrarily, with the important caveat that no more than the original offer item amounts can be spent.
 - As all criteria-based items are tied to a particular token, there is no native way to construct orders where items specify cross-token criteria. Additionally, each potential identifier for a particular criteria-based item must have the same amount as any other identifier.

@@ -156,7 +156,7 @@ When matching a group of orders via `matchOrders` or `matchAdvancedOrders`, step
 - As all offer and consideration items are allocated against one another in memory, there are scenarios in which the actual received item amount will differ from the amount specified by the order — notably, this includes items with a fee-on-transfer mechanic. Orders that contain items of this nature (or, more broadly, items that have some post-fulfillment state that should be met) should leverage "restricted" order types and route the order fulfillment through a zone contract that performs the necessary checks after order fulfillment is completed.
 - As all offer items are taken directly from the offerer and all consideration items are given directly to the named recipient, there are scenarios where those accounts can increase the gas cost of order fulfillment or block orders from being fulfilled outright depending on the item being transferred. If the item in question is Ether or a similar native token, a recipient can throw in the payable fallback or even spend excess gas from the submitter. Similar mechanics can be leveraged by both offerers and receivers if the item in question is a token with a transfer hook (like ERC1155 and ERC777) or a non-standard token implementation. Potential remediations to this category of issue include wrapping Ether as WETH as a fallback if the initial transfer fails and allowing submitters to specify the amount of gas that should be allocated as part of a given fulfillment. Orders that support explicit fulfillments can also elect to leave problematic or unwanted offer items unspent as long as all consideration items are received in full.
 - As fulfillments may be executed in whatever sequence the fulfiller specifies as long as the fulfillments are all executable, as restricted orders are validated via zones prior to execution, and as orders may be combined with other orders or have additional consideration items supplied, any items with modifiable state are at risk of having that state modified during execution if a payable Ether recipient or onReceived 1155 transfer hook is able to modify that state. By way of example, imagine an offerer offers WETH and requires some ERC721 item as consideration, where the ERC721 should have some additional property like not having been used to mint some other ERC721 item. Then, even if the offerer enforces that the ERC721 have that property via a restricted order that checks for the property, a malicious fulfiller could include a second order (or even just an additional consideration item) that uses the ERC721 item being sold to mint before it is transferred to the offerer. One category of remediation for this problem is to use restricted orders that do not implement `isValidOrder` and actually require that order fulfillment is routed through them so that they can perform post-fulfillment validation. Another interesting solution to this problem that retains order composability is to "fight fire with fire" and have the offerer include a "validator" ERC1155 consideration item on orders that require additional assurances; this would be a contract that contains the ERC1155 interface but is not actually an 1155 token, and instead leverages the `onReceived` hook as a means to validate that the expected invariants were upheld, reverting the "transfer" if the check fails (so in the case of the example above, this hook would ensure that the offerer was the owner of the ERC721 item in question and that it had not yet been used to mint the other ERC721). The key limitation to this mechanic is the amount of data that can be supplied in-band via this route; only three arguments ("from", "identifier", and "amount") are available to utilize.
-- As all consideration items are supplied at the time of order creation, dynamic adjustment of recipients or amounts after creation (e.g. modifications to royalty payout info) is not supported. However, a zone can enforce that a given restricted order contains _new_ dynamically computed consideration items by deriving them and either supplying them manually or ensuring that they are present via `isValidZoneIncludingExtraData` since consideration items can be extended arbitrarily, with the important caveat that no more than the original offer item amounts can be spent.

 - As all criteria-based items are tied to a particular token, there is no native way to construct orders where items specify cross-token criteria. Additionally, each potential identifier for a particular criteria-based item must have the same amount as any other identifier.
 - As orders that contain items with ascending or descending amounts may not be filled as quickly as a fulfiller would like (e.g. transactions taking longer than expected to be included), there is a risk that fulfillment on those orders will supply a larger item amount, or receive back a smaller item amount, than they intended or expected. One way to prevent these outcomes is to utilize `matchOrders`, supplying a contrasting order for the fulfiller that explicitly specifies the maximum allowable offer items to be spent and consideration items to be received back. Special care should be taken when handling orders that contain both brief durations as well as items with ascending or descending amounts, as realized amounts may shift appreciably in a short window of time.
 - As all items on orders supporting partial fills must be "cleanly divisible" when performing a partial fill, orders with multiple items should be constructed with care. A straightforward heuristic is to start with a "unit" bundle (e.g. 1 NFT item A, 3 NFT item B, and 5 NFT item C for 2 ETH) then applying a multiple to that unit bundle (e.g. 7 of those units results in a partial order for 7 NFT item A, 21 NFT item B, and 35 NFT item C for 14 ETH).

Subject: [PATCH 0810/1239] Add STOP prefix to TypehashDirectory

This is not strictly necessary, as the first byte is known to be EXTCODECOPY which can not be executed; however, it would be easy to overlook in a future update which modifies the OrderComponents type and it is generally poor practice to store generated data without a stop prefix.

 While the standard method can technically be used for fulfilling any order, it suffers from key efficiency limitations in certain scenarios:
 
@@ -156,7 +156,7 @@ When matching a group of orders via `matchOrders` or `matchAdvancedOrders`, step
 - As all offer and consideration items are allocated against one another in memory, there are scenarios in which the actual received item amount will differ from the amount specified by the order — notably, this includes items with a fee-on-transfer mechanic. Orders that contain items of this nature (or, more broadly, items that have some post-fulfillment state that should be met) should leverage "restricted" order types and route the order fulfillment through a zone contract that performs the necessary checks after order fulfillment is completed.
 - As all offer items are taken directly from the offerer and all consideration items are given directly to the named recipient, there are scenarios where those accounts can increase the gas cost of order fulfillment or block orders from being fulfilled outright depending on the item being transferred. If the item in question is Ether or a similar native token, a recipient can throw in the payable fallback or even spend excess gas from the submitter. Similar mechanics can be leveraged by both offerers and receivers if the item in question is a token with a transfer hook (like ERC1155 and ERC777) or a non-standard token implementation. Potential remediations to this category of issue include wrapping Ether as WETH as a fallback if the initial transfer fails and allowing submitters to specify the amount of gas that should be allocated as part of a given fulfillment. Orders that support explicit fulfillments can also elect to leave problematic or unwanted offer items unspent as long as all consideration items are received in full.
 - As fulfillments may be executed in whatever sequence the fulfiller specifies as long as the fulfillments are all executable, as restricted orders are validated via zones prior to execution, and as orders may be combined with other orders or have additional consideration items supplied, any items with modifiable state are at risk of having that state modified during execution if a payable Ether recipient or onReceived 1155 transfer hook is able to modify that state. By way of example, imagine an offerer offers WETH and requires some ERC721 item as consideration, where the ERC721 should have some additional property like not having been used to mint some other ERC721 item. Then, even if the offerer enforces that the ERC721 have that property via a restricted order that checks for the property, a malicious fulfiller could include a second order (or even just an additional consideration item) that uses the ERC721 item being sold to mint before it is transferred to the offerer. One category of remediation for this problem is to use restricted orders that do not implement `isValidOrder` and actually require that order fulfillment is routed through them so that they can perform post-fulfillment validation. Another interesting solution to this problem that retains order composability is to "fight fire with fire" and have the offerer include a "validator" ERC1155 consideration item on orders that require additional assurances; this would be a contract that contains the ERC1155 interface but is not actually an 1155 token, and instead leverages the `onReceived` hook as a means to validate that the expected invariants were upheld, reverting the "transfer" if the check fails (so in the case of the example above, this hook would ensure that the offerer was the owner of the ERC721 item in question and that it had not yet been used to mint the other ERC721). The key limitation to this mechanic is the amount of data that can be supplied in-band via this route; only three arguments ("from", "identifier", and "amount") are available to utilize.
-- As all consideration items are supplied at the time of order creation, dynamic adjustment of recipients or amounts after creation (e.g. modifications to royalty payout info) is not supported. However, a zone can enforce that a given restricted order contains _new_ dynamically computed consideration items by deriving them and either supplying them manually or ensuring that they are present via `isValidOrderIncludingExtraData` since consideration items can be extended arbitrarily, with the important caveat that no more than the original offer item amounts can be spent.

 - As all criteria-based items are tied to a particular token, there is no native way to construct orders where items specify cross-token criteria. Additionally, each potential identifier for a particular criteria-based item must have the same amount as any other identifier.
 - As orders that contain items with ascending or descending amounts may not be filled as quickly as a fulfiller would like (e.g. transactions taking longer than expected to be included), there is a risk that fulfillment on those orders will supply a larger item amount, or receive back a smaller item amount, than they intended or expected. One way to prevent these outcomes is to utilize `matchOrders`, supplying a contrasting order for the fulfiller that explicitly specifies the maximum allowable offer items to be spent and consideration items to be received back. Special care should be taken when handling orders that contain both brief durations as well as items with ascending or descending amounts, as realized amounts may shift appreciably in a short window of time.
 - As all items on orders supporting partial fills must be "cleanly divisible" when performing a partial fill, orders with multiple items should be constructed with care. A straightforward heuristic is to start with a "unit" bundle (e.g. 1 NFT item A, 3 NFT item B, and 5 NFT item C for 2 ETH) then applying a multiple to that unit bundle (e.g. 7 of those units results in a partial order for 7 NFT item A, 21 NFT item B, and 35 NFT item C for 14 ETH).

+  - `CONTRACT` indicates that the order will be generated by the offerer upon a call from Seaport to `generateOrder`, then verified after execution with a follow-on call to `ratifyOrder` on the offerer.
 - The `startTime` indicates the block timestamp at which the order becomes active.

 - Calling one of two "fulfill available" functions, `fulfillAvailableOrders` and `fulfillAvailableAdvancedOrders`, where a group of orders are supplied alongside a group of fulfillments specifying which offer items can be aggregated into distinct transfers and which consideration items can be accordingly aggregated, and where any orders that have been cancelled, have an invalid time, or have already been fully filled will be skipped without causing the rest of the available orders to revert. Additionally, any remaining orders will be skipped once `maximumFulfilled` available orders have been located.

 While the standard method can technically be used for fulfilling any order, it suffers from key efficiency limitations in certain scenarios:
 
@@ -156,7 +157,7 @@ When matching a group of orders via `matchOrders` or `matchAdvancedOrders`, step
 - As all offer and consideration items are allocated against one another in memory, there are scenarios in which the actual received item amount will differ from the amount specified by the order — notably, this includes items with a fee-on-transfer mechanic. Orders that contain items of this nature (or, more broadly, items that have some post-fulfillment state that should be met) should leverage "restricted" order types and route the order fulfillment through a zone contract that performs the necessary checks after order fulfillment is completed.
 - As all offer items are taken directly from the offerer and all consideration items are given directly to the named recipient, there are scenarios where those accounts can increase the gas cost of order fulfillment or block orders from being fulfilled outright depending on the item being transferred. If the item in question is Ether or a similar native token, a recipient can throw in the payable fallback or even spend excess gas from the submitter. Similar mechanics can be leveraged by both offerers and receivers if the item in question is a token with a transfer hook (like ERC1155 and ERC777) or a non-standard token implementation. Potential remediations to this category of issue include wrapping Ether as WETH as a fallback if the initial transfer fails and allowing submitters to specify the amount of gas that should be allocated as part of a given fulfillment. Orders that support explicit fulfillments can also elect to leave problematic or unwanted offer items unspent as long as all consideration items are received in full.
 - As fulfillments may be executed in whatever sequence the fulfiller specifies as long as the fulfillments are all executable, as restricted orders are validated via zones prior to execution, and as orders may be combined with other orders or have additional consideration items supplied, any items with modifiable state are at risk of having that state modified during execution if a payable Ether recipient or onReceived 1155 transfer hook is able to modify that state. By way of example, imagine an offerer offers WETH and requires some ERC721 item as consideration, where the ERC721 should have some additional property like not having been used to mint some other ERC721 item. Then, even if the offerer enforces that the ERC721 have that property via a restricted order that checks for the property, a malicious fulfiller could include a second order (or even just an additional consideration item) that uses the ERC721 item being sold to mint before it is transferred to the offerer. One category of remediation for this problem is to use restricted orders that do not implement `isValidOrder` and actually require that order fulfillment is routed through them so that they can perform post-fulfillment validation. Another interesting solution to this problem that retains order composability is to "fight fire with fire" and have the offerer include a "validator" ERC1155 consideration item on orders that require additional assurances; this would be a contract that contains the ERC1155 interface but is not actually an 1155 token, and instead leverages the `onReceived` hook as a means to validate that the expected invariants were upheld, reverting the "transfer" if the check fails (so in the case of the example above, this hook would ensure that the offerer was the owner of the ERC721 item in question and that it had not yet been used to mint the other ERC721). The key limitation to this mechanic is the amount of data that can be supplied in-band via this route; only three arguments ("from", "identifier", and "amount") are available to utilize.
-- As all consideration items are supplied at the time of order creation, dynamic adjustment of recipients or amounts after creation (e.g. modifications to royalty payout info) is not supported. However, a zone can enforce that a given restricted order contains _new_ dynamically computed consideration items by deriving them and either supplying them manually or ensuring that they are present via `validateOrder` or `ratifyOrder` since consideration items can be extended arbitrarily, with the important caveat that no more than the original offer item amounts can be spent.

 - As all criteria-based items are tied to a particular token, there is no native way to construct orders where items specify cross-token criteria. Additionally, each potential identifier for a particular criteria-based item must have the same amount as any other identifier.
 - As orders that contain items with ascending or descending amounts may not be filled as quickly as a fulfiller would like (e.g. transactions taking longer than expected to be included), there is a risk that fulfillment on those orders will supply a larger item amount, or receive back a smaller item amount, than they intended or expected. One way to prevent these outcomes is to utilize `matchOrders`, supplying a contrasting order for the fulfiller that explicitly specifies the maximum allowable offer items to be spent and consideration items to be received back. Special care should be taken when handling orders that contain both brief durations as well as items with ascending or descending amounts, as realized amounts may shift appreciably in a short window of time.
 - As all items on orders supporting partial fills must be "cleanly divisible" when performing a partial fill, orders with multiple items should be constructed with care. A straightforward heuristic is to start with a "unit" bundle (e.g. 1 NFT item A, 3 NFT item B, and 5 NFT item C for 2 ETH) then applying a multiple to that unit bundle (e.g. 7 of those units results in a partial order for 7 NFT item A, 21 NFT item B, and 35 NFT item C for 14 ETH).

 Seaport also includes a suite of fuzzing tests written in solidity with Foundry.
 
-To install Foundry (assuming a Linux or macOS system):
+To run tests with full traces and debugging with source, create an `.env` file with the following line:
 
 ```bash
-curl -L https://foundry.paradigm.xyz | bash
+FOUNDRY_PROFILE=debug
 ```
 
-This will download foundryup. To start Foundry, run:
+You may then run tests with `forge test`, optionally specifying a level of verbosity (anywhere from one to five `v`'s, eg, `-vvv`)
 
-```bash
-foundryup
-```
-
-To install dependencies:
 
-```
-forge install
-```
+This will compile tests and contracts without `via-ir` enabled, which is must faster, but will not exactly match the deployed bytecode. 
 
-To precompile contracts:
 
-The optimized contracts are compiled using the IR pipeline, which can take a long time to compile. By default, the differential test suite deploys precompiled versions of both the optimized and reference contracts. Precompilation can be done by specifying specific Foundry profiles.
+To run tests against the actual bytecode intended to be deployed on networks, you will need to pre-compile the contracts, and remove the `FOUNDRY_PROFILE` variable from your `.env` file. **Note** that informative error traces may not be available, and the Forge debugger will not show the accompanying source code. 
 
 ```bash
 FOUNDRY_PROFILE=optimized forge build
 FOUNDRY_PROFILE=reference forge build
 ```
 
-There are three Foundry profiles for running the test suites, which bypass the IR pipeline to speed up compilation. To run tests, run any of the following:
-
-```bash
-FOUNDRY_PROFILE=test forge test # with 5000 fuzz runs
-FOUNDRY_PROFILE=lite forge test # with 1000 fuzz runs
-FOUNDRY_PROFILE=local forge test # compiles and deploys ReferenceConsideration normally, with 1000 fuzz runs
-FOUNDRY_PROFILE=debug forge test # compiles and deploys Consideration and ReferenceConsideration using default profile solc settings, not from precompiled source, with 1000 fuzz runs
-```
-
-You may wish to include a `.env` file that `export`s a specific profile when developing locally.
-
-**Note** that stack+debug traces will not be available for precompiled contracts. To facilitate local development, specifying `FOUNDRY_PROFILE=local` will compile and deploy the reference implementation normally, allowing for stack+debug traces.
-
-**Note** the `local` profile uses Forge's `ffi` flag. `ffi` can potentially be unsafe, as it allows Forge to execute arbitrary code. Use with caution, and always ensure you trust the code in this repository, especially when working on third-party forks.
-
-The following modifiers are also available:
-
-- Level 2 (-vv): Logs emitted during tests are also displayed.
-- Level 3 (-vvv): Stack traces for failing tests are also displayed.
-- Level 4 (-vvvv): Stack traces for all tests are displayed, and setup traces for failing tests are displayed.
-- Level 5 (-vvvvv): Stack traces and setup traces are always displayed.
-
-```bash
-FOUNDRY_PROFILE=test forge test  -vv
-```
-

 > Note: When a collection-wide criteria-based item (criteria = 0) is provided as an input to a contract order, the contract offerer has full latitude to choose any identifier they want mid-flight, which differs from the usual behavior.  For regular criteria-based orders with identifierOrCriteria = 0, the fulfiller can pick which identifier to receive by providing a CriteriaResolver. For contract offers with identifierOrCriteria = 0, Seaport does not expect a corresponding CriteriaResolver, and will revert if one is provided.  See `_getGeneratedOrder` and `_compareItems` for more detail.
 
+> Note: Calls to Seaport that would fulfill or match a collection of advanced orders can be monitored and where there are unused offer items, it's possible for a third party to claim them. Anyone can monitor the mempool to find calls to `fulfillAvailableOrders`, `fulfillAvailableAdvancedOrders`, `matchOrders`, `matchAdvancedOrders` and calculate if there are any unused offer item amounts.  If there are unused offer item amounts, the third party can create orders with no offer items, but with consideration items mirroring the unused offer items and populate the fulfillment aggregation data to match the unused offer items with the new mirrored consideration items.  This would allow the third party to claim the unused offer items.  A contract offerer or a zone could prevent this, but by default, it's possible.

 ### Balance and Approval Requirements
 
 When creating an offer, the following requirements should be checked to ensure that the order will be fulfillable:

@@ -51,7 +51,7 @@ Orders are fulfilled via one of four methods:
   - If the order has an ERC721 item, that item has an amount of `1`.
   - If the order has multiple consideration items and all consideration items other than the first consideration item have the same item type as the offered item, the offered item amount is not less than the sum of all consideration item amounts excluding the first consideration item amount.
 - Calling one of two "fulfill available" functions, `fulfillAvailableOrders` and `fulfillAvailableAdvancedOrders`, where a group of orders are supplied alongside a group of fulfillments specifying which offer items can be aggregated into distinct transfers and which consideration items can be accordingly aggregated, and where any orders that have been cancelled, have an invalid time, or have already been fully filled will be skipped without causing the rest of the available orders to revert. Additionally, any remaining orders will be skipped once `maximumFulfilled` available orders have been located. Similar to the standard fulfillment method, all offer items will be transferred from the respective offerer to the fulfiller, then all consideration items will be transferred from the fulfiller to the named recipient.
-- Calling one of two "match" functions, `matchOrders` and `matchAdvancedOrders`, where a group of explicit orders are supplied alongside a group of fulfillments specifying which offer items to apply to which consideration items (and with the "advanced" case operating in a similar fashion to the standard method, but supporting partial fills via supplied `numerator` and `denominator` fractional values as well as an optional `extraData` argument that will be supplied as part of a call to the `validateOrder` function when fulfilling restricted order types or to `generateOrder` and `ratifyOrder` as "context" on contract order types). Note that orders fulfilled in this manner do not have an explicit fulfiller; instead, Seaport will simply ensure coincidence of wants across each order.

Note that orders fulfilled in this manner do not have an explicit fulfiller; instead, Seaport will simply ensure coincidence of wants across each order.  Note also that contract orders do not enforce usage of a specific conduit, but a contract offerer can require the usage of a specific conduit by setting allowances or approval on tokens for specific conduits.  If a fulfiller does not supply the correct conduit key, the call will revert.  There's currently no endpoint for finding which conduit a given contract offerer prefers.
 
 While the standard method can technically be used for fulfilling any order, it suffers from key efficiency limitations in certain scenarios:

   - The zone may cancel orders where it is named as the zone by calling `cancel`. (Note that offerers can also cancel their own orders, either individually or for all orders signed with their current counter at once by calling `incrementCounter`).
   - "Restricted" orders (as specified by the order type) must either be executed by the zone or the offerer, or must be approved as indicated by a call to an `isValidOrder` or `isValidOrderIncludingExtraData` view function on the zone.
 - The `offer` contains an array of items that may be transferred from the offerer's account, where each item consists of the following components:
-  - The `itemType` designates the type of item, with valid types being Ether (or other native token for the given chain), ERC20, ERC721, ERC1155, ERC721 with "criteria" (explained below), and ERC1155 with criteria.
+  - The `itemType` designates the type of item, with valid types being:
+    * Ether (or other native token for the given chain) enum value: `NATIVE = 0`
+    * ERC20: enum value: `ERC20 = 1`
+    * ERC721: enum value: `ERC721 = 2`
+    * ERC1155: enum value: `ERC1155 = 3`
+    * ERC721 with "criteria" (explained below): enum value: `ERC721_WITH_CRITERIA = 4`
+    * ERC1155 with "criteria" (explained below): enum value: `ERC1155_WITH_CRITERIA = 5`
   - The `token` designates the account of the item's token contract (with the null address used for Ether or other native tokens).
   - The `identifierOrCriteria` represents either the ERC721 or ERC1155 token identifier or, in the case of a criteria-based item type, a merkle root composed of the valid set of token identifiers for the item. This value will be ignored for Ether and ERC20 item types, and can optionally be zero for criteria-based item types to allow for any identifier.
   - The `startAmount` represents the amount of the item in question that will be required should the order be fulfilled at the moment the order becomes active.

 > Note: Calls to Seaport that would fulfill or match a collection of advanced orders can be monitored and where there are unused offer items, it's possible for a third party to claim them. Anyone can monitor the mempool to find calls to `fulfillAvailableOrders`, `fulfillAvailableAdvancedOrders`, `matchOrders`, `matchAdvancedOrders` and calculate if there are any unused offer item amounts.  If there are unused offer item amounts, the third party can create orders with no offer items, but with consideration items mirroring the unused offer items and populate the fulfillment aggregation data to match the unused offer items with the new mirrored consideration items.  This would allow the third party to claim the unused offer items.  A contract offerer or a zone could prevent this, but by default, it's possible.
 
+> Note: Contract orders can supply additional offer amounts when the order is executed. However, if they supply extra offer items with criteria, on the fly, the fulfiller won't be able to supply the necessary criteria resolvers, which would make fulfilling the order infeasible.  Contract offerers should specifically avoid returning criteria-based items and generally avoid mismatches between previewOrder and what's executed on-chain.
+
+> Note: In some cases, contract offerers will be able to lower the value of an offered NFT by transferring out valuable tokens that are attached to the NFT.  For example, a contract offerer could transfer out a Koda when Seaport calls `generateOrder`.  Consider using a mirrored order that allows for a post-transfer validation, such as a contract order or a restricted order, in cases like this.

 ### Balance and Approval Requirements
 
 When creating an offer, the following requirements should be checked to ensure that the order will be fulfillable:

 > Note: Contract orders can supply additional offer amounts when the order is executed. However, if they supply extra offer items with criteria, on the fly, the fulfiller won't be able to supply the necessary criteria resolvers, which would make fulfilling the order infeasible.  Contract offerers should specifically avoid returning criteria-based items and generally avoid mismatches between previewOrder and what's executed on-chain.
 
-> Note: In some cases, contract offerers will be able to lower the value of an offered NFT by transferring out valuable tokens that are attached to the NFT.  For example, a contract offerer could transfer out a Koda when Seaport calls `generateOrder`.  Consider using a mirrored order that allows for a post-transfer validation, such as a contract order or a restricted order, in cases like this.

 ## Verifying Seaport and ConduitController
 After `Seaport` and `ConduitController` are deployed, they are verified as follows:
 
-1. Ensure that `EXPLORER_API_KEY` and `NETWORK_RPC` are set in `.env` appropriatly.
-2. Verify `ConduitController` by calling:
