EIP-3009 message types.

  • Note that some contracts e.g. Polygon’s bridged USDC only implement TransferWithAuthorization support. Always check your target token first for supported methods.

  • Use ReceiveWithAuthorization when possible as it is safer due to front running protection

See make_eip_3009_transfer() for more information.
