Seaport Order Validator

The SeaportValidator contract offers various validation methods to ensure that supplied Seaport orders are being constructed correctly. Most contract calls return an ErrorsAndWarnings struct with two uint16 arrays to help developers debug issues with their orders.

See below for the full list of Errors and Warnings.

The contract is deployed to the following addresses:

Contract	Canonical Cross-chain Deployment Address
SeaportValidator	0x00e5F120f500006757E984F1DED400fc00370000
SeaportValidator 1.1 (legacy)	0xF75194740067D6E4000000003b350688DD770000
SeaportValidator 1.4 (legacy)	0x00000000BE3Af6882A06323fd3f400A9e6A0DC42
SeaportValidator 1.5 (legacy)	0x000000000DD1F1B245b936b2771408555CF8B8af

Special thanks to:

• arr00, who deployed an earlier version of a SeaportValidator contract which can be found here
• stephankmin, who extended the SeaportValidator contract to support more errors/warnings and arbitary Seaport instances with compatible versions
• horsefacts, who implemented support for a read-only version of the helper contract
