createmultisig

createmultisig nrequired ["key",...] ( "address_type" ) Creates a multi-signature address with n signature of m keys required. It returns a json object with the address and redeemScript. Arguments: 1. nrequired (numeric, required) The number of required signatures out of the n keys. 2. keys (json array, required) The hex-encoded public keys. [ "key", (string) The hex-encoded public key ... ] 3. address_type (string, optional, default="legacy") The address type to use. Options are "legacy", "p2sh-segwit", and "bech32". Result: { (json object) "address" : "str", (string) The value of the new multisig address. "redeemScript" : "hex", (string) The string value of the hex-encoded redemption script. "descriptor" : "str", (string) The descriptor for this multisig "warnings" : [ (json array, optional) Any warnings resulting from the creation of this multisig "str", (string) ... ] } Examples: Create a multisig address from 2 public keys > bitcoin-cli createmultisig 2 "[\"03789ed0bb717d88f7d321a368d905e7430207ebbd82bd342cf11ae157a7ace5fd\",\"03dbc6764b8884a92e871274b87583e6d5c2a58819473e17e107ef3f6aa5a61626\"]" As a JSON-RPC call > curl --user myusername --data-binary '{"jsonrpc": "2.0", "id": "curltest", "method": "createmultisig", "params": [2, ["03789ed0bb717d88f7d321a368d905e7430207ebbd82bd342cf11ae157a7ace5fd","03dbc6764b8884a92e871274b87583e6d5c2a58819473e17e107ef3f6aa5a61626"]]}' -H 'content-type: application/json' http://127.0.0.1:8332/
