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 ready-only version of the helper contract
