Verification

You need a key and a signature from a cip30 datasignature. Use e.g. window.cardano."wallet_name".enable().then(api => api.signData(...)) or the signMessage function of the cardano-connect-with-wallet library to get a valid key and signature.

The plain message and/or the readable address can be provided for testing optionally. Checkout this examples.

verifySignature: (
  signature: string,
  key: string,
  message?: string,
  address?: string
) => boolean;
