Signing_and_Verifying_Messages

Cryptographically signed messages are a useful feature which can be used to prove ownership of an address.

If your coins file contains the correct sign_message_prefix parameter value for a coin, you can sign messages with the Komodo DeFi Framework API. For signing with a HD wallet, the coins file must also contain the coin's derivation path prefix.

    ...
    "sign_message_prefix": "DigiByte Signed Message:\n",
