BatchOrderTypehashRegistry

The contract generates the batch order hash that is used to compute the digest for signature verification.

hashBatchOrder

function hashBatchOrder(bytes32 root, uint256 proofLength) public pure returns (bytes32 batchOrderHash)

This function returns the hash of the concatenation of batch order type hash and merkle root.

Parameters

Name	Type	Description
root	bytes32	Merkle root
proofLength	uint256	Merkle proof length

Return Values

Name	Type	Description
batchOrderHash	bytes32	The batch order hash

_getBatchOrderTypehash

function _getBatchOrderTypehash(uint256 height) internal pure returns (bytes32 typehash)

It looks like this for each height

height == 1: BatchOrder(Maker[2] tree)Maker(uint8 quoteType,uint256 globalNonce,uint256 subsetNonce,uint256 orderNonce,uint256 strategyId,uint8 collectionType,address collection,address currency,address signer,uint256 startTime,uint256 endTime,uint256 price,uint256[] itemIds,uint256[] amounts,bytes additionalParameters)

height == 2: BatchOrder(Maker[2][2] tree)Maker(uint8 quoteType,uint256 globalNonce,uint256 subsetNonce,uint256 orderNonce,uint256 strategyId,uint8 collectionType,address collection,address currency,address signer,uint256 startTime,uint256 endTime,uint256 price,uint256[] itemIds,uint256[] amounts,bytes additionalParameters)

height == n: BatchOrder(Maker[2]...[2] tree)Maker(uint8 quoteType,uint256 globalNonce,uint256 subsetNonce,uint256 orderNonce,uint256 strategyId,uint8 collectionType,address collection,address currency,address signer,uint256 startTime,uint256 endTime,uint256 price,uint256[] itemIds,uint256[] amounts,bytes additionalParameters)
