adaptor.partial

adaptor.partial "psbt" Produce partial adaptor signatures for wallet-controlled Taproot inputs (key-path or annotated script-path). Arguments: 1. psbt (string, required) Base64-encoded PSBT Result: { (json object) "psbt" : "str", (string) Updated PSBT "complete" : true|false, (boolean) Whether all inputs now have final taproot signatures "hex" : "hex", (string, optional) Final transaction hex (present when complete=true and extraction succeeded) "txid" : "hex" (string, optional) Transaction id (present when hex is returned) } Examples: > bitcoin-cli adaptor.prepare "psbt_base64"

Signature

adaptor.partial(psbt: string) → any
