walletprocesspsbt

walletprocesspsbt "psbt" ( sign "sighashtype" bip32derivs finalize ) Update a PSBT with input information from our wallet and then sign inputs that we can sign for. Requires wallet passphrase to be set with walletpassphrase call if wallet is encrypted. Arguments: 1. psbt (string, required) The transaction base64 string 2. sign (boolean, optional, default=true) Also sign the transaction when updating (requires wallet to be unlocked) 3. sighashtype (string, optional, default="DEFAULT for Taproot, ALL otherwise") The signature hash type to sign with if not specified by the PSBT. Must be one of "DEFAULT" "ALL" "NONE" "SINGLE" "ALL|ANYONECANPAY" "NONE|ANYONECANPAY" "SINGLE|ANYONECANPAY" 4. bip32derivs (boolean, optional, default=true) Include BIP 32 derivation paths for public keys if we know them 5. finalize (boolean, optional, default=true) Also finalize inputs if possible Result: { (json object) "psbt" : "str", (string) The base64-encoded partially signed transaction "complete" : true|false, (boolean) If the transaction has a complete set of signatures "hex" : "hex" (string, optional) The hex-encoded network transaction if complete } Examples: > bitcoin-cli walletprocesspsbt "psbt"

Signature

walletprocesspsbt(psbt: string, sign?: boolean, sighashtype?: string, bip32derivs?: boolean, finalize?: boolean) → any
