signmessagebip322

signmessagebip322 "address" "message" Sign a message using BIP-322 format for any address type (P2WPKH, P2WSH, P2TR, etc.) This produces a signature that can be verified with verifymessagebip322. Requires wallet passphrase to be set with walletpassphrase call if wallet is encrypted. Arguments: 1. address (string, required) The bitcoin address to use for signing. 2. message (string, required) The message to sign. Result: "str" (string) The BIP-322 signature encoded in base64 Examples: Unlock the wallet for 30 seconds > bitcoin-cli walletpassphrase "mypassphrase" 30 Create the signature > bitcoin-cli signmessagebip322 "bc1q..." "TENSORCASH_GOVERNANCE:..." Verify the signature > bitcoin-cli verifymessagebip322 "bc1q..." "<signature>" "TENSORCASH_GOVERNANCE:..." As a JSON-RPC call > curl --user myusername --data-binary '{"jsonrpc": "2.0", "id": "curltest", "method": "signmessagebip322", "params": ["bc1q...", "TENSORCASH_GOVERNANCE:..."]}' -H 'content-type: application/json' http://127.0.0.1:8332/
