signmldsatransactionwithwallet "hexstring" [{"txid":"hex","vout":n,"scriptPubKey":"hex","amount":amount},...] ( "sighashtype" ) Sign ML-DSA transaction inputs using keys from wallet. This RPC automatically looks up ML-DSA signing data in the wallet for all ML-DSA (witness v2) inputs. Arguments: 1. hexstring (string, required) The raw transaction hex string 2. prevtxs (json array, required) Previous transaction outputs being spent [ { (json object) "txid": "hex", (string, required) Transaction ID "vout": n, (numeric, required) Output index "scriptPubKey": "hex", (string, required) scriptPubKey of output "amount": amount, (numeric or string, required) Output value in BTC }, ... ] 3. sighashtype (string, optional, default="ALL") The sighash type (ALL, NONE, SINGLE, etc.) Result: { (json object) "hex" : "hex", (string) The signed transaction hex "complete" : true|false, (boolean) Whether the transaction is fully signed "errors" : [ (json array, optional) Signing errors { (json object) "input_index" : n, (numeric) Input index that failed "error" : "str" (string) Error message }, ... ] } Examples: > bitcoin-cli signmldsatransactionwithwallet "<hex>" '[{"txid":"...","vout":0,"scriptPubKey":"...","amount":0.01}]' > curl --user myusername --data-binary '{"jsonrpc": "2.0", "id": "curltest", "method": "signmldsatransactionwithwallet", "params": ["<hex>", [{"txid":"...","vout":0,"scriptPubKey":"...","amount":0.01}]]}' -H 'content-type: application/json' http://127.0.0.1:8332/
