Send a Multi-Signed Transaction
Reference the XRP Doc​
Multi-signing a Transaction
1.First, prepare by referring to Set Up Multi-Signing (You can get address of account using getAddress() function.)
2.Get signature
Example
// You can use xrp library for encoding
//const api = require('ripple-binary-codec')
//const addrs = require('ripple-address-codec')
​
const transactionJson = {
    "TransactionType": "Payment",
    "Account": "rfQrsnD8ywrgSX457qshpBTDru7EDnM2Lb",
    "Fee": "30", // normal cost * (1 + N)
    "Sequence": 45,
    "Amount": "1234567",
    "Flags": 2147483648,
    "Destination": "rJZMdVmbqFPi5oMyzGKJhHW9mNHwpiYKpS",
    "SigningPubKey": "", // Must be blank
}
​
var result
var signer = {}
try {
    // Keypath is SignerEntry's key path
    result = await DcentWebConnector.getXrpSignedTransaction(transactionJson, "m/44'/144'/1'/0/0");
    signer = {
        "Account": "rBV2LGGm5XAc5KbL7hBaPnLnUJ5aTQzVj9", // addrs.encodeAccountID(Buffer.from(result.accountId,'hex'))
        "SigningPubKey": result.pubkey,
        "TxnSignature": result.sign
    }
} catch (e) {
    console.log(e)
    result = e
}
For broadcast the sign transaction, you must reconstruct transaction include TxnSignature & SigningPubKey for normal (single-signature) or Signers array for multi-signed-transaction
