addmultisigaddress

addmultisigaddress nrequired [“key”,…] ( “account” “address_type” )

Add a nrequired-to-sign multisignature address to the wallet. Requires a new wallet backup. Each key is a Bitcoin address or hex-encoded public key. This functionality is only intended for use with non-watchonly addresses. See importaddress for watchonly p2sh address support. If ‘account’ is specified (DEPRECATED), assign address to that account.

Arguments:

nrequired (numeric, required) The number of required signatures out of the n keys or addresses.
“keys” (string, required) A json array of bitcoin addresses or hex-encoded public keys [ “address” (string) bitcoin address or hex-encoded public key …, ]
“account” (string, optional) DEPRECATED. An account to assign the addresses to.
“address_type” (string, optional) The address type to use. Options are “legacy”, “p2sh-segwit”, and “bech32”. Default is set by -addresstype.

Result: { “address”:“multisigaddress”, (string) The value of the new multisig address. “redeemScript”:“script” (string) The string value of the hex-encoded redemption script. }

Result (DEPRECATED. To see this result in v0.16 instead, please start bitcoind with -deprecatedrpc=addmultisigaddress). clients should transition to the new output api before upgrading to v0.17. “address” (string) A bitcoin address associated with the keys.

Examples:

Add a multisig address from 2 addresses

bitcoin-cli addmultisigaddress 2 ”[“16sSauSf5pF2UkUwvKGq4qjNRzBZYqgEL5”,“171sgjn4YtPu27adkKGrdDwzRTxnRkBfKV”]”
