PreApprove

On-chain registry for pre-approvals of ERC721 transfers.

This codebase is still under construction.

TODO:

• A simple stateless library for calling isPreApproved on the registry in the most efficient way possible.

• ERC721A, ERC721, ERC1155 examples with overriden isApprovedForAll.

• For development and testing:

  • First, compile the registry and get its initcode.

  • Use vm.etch to write the bytecode of 0x0000000000ffe8b47b3e2130213b802212439497 (ImmutableCreate2Factory by z0age).

  • Call the safeCreate2(bytes32 salt, bytes calldata initializationCode) on ImmutableCreate2Factory.

  • Test if the registry works (subclass PreApproveRegistryTest).
