API Specification​

EVM Compatible Blockchains

VerificationProvider

Code
abstract contract VerificationProvider {
  // verify is to check if the user is verified in the partner's system
  function verify(address addr) external view virtual returns (bool pass, string memory message);
}

You are required to implement the VerificationProvider contract in your smart contract. The verify function should return true if the verification is successful, otherwise false. The message should contain the reason for the failure.

Example

Code
contract Example is VerificationProvider {
  function verify(address user) external view override returns (bool pass, string memory message)
  {
    if (user == address(0)) {
      return (false, "Invalid address");
    }

    return (true, "Verified");
  }
}
