v0.16.2

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:
1. nrequired                      (numeric, required) The number of required signatures out of the n keys or addresses.
2. "keys"                         (string, required) A json array of bitcoin addresses or hex-encoded public keys
     [
       "address"                  (string) bitcoin address or hex-encoded public key
       ...,
     ]
3. "account"                      (string, optional) DEPRECATED. An account to assign the addresses to.
4. "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.
