xrpl_signTransactionFor

xrpl_signTransactionFor adds a single Signers entry for the connected account, over the transaction exactly as sent. It never autofills and never submits: you collect signatures from every signer, combine them, and submit.

#Request

{
  tx_json: Transaction; // Account is the multisigned account, not the connected one
  tx_signer?: string;   // if present, must be the connected account
  submit?: false;       // submit: true is refused
}

#Usage

const result = await provider.request(
  {
    method: 'xrpl_signTransactionFor',
    params: {
      tx_signer: 'r…', // the connected account
      tx_json: {
        TransactionType: 'Payment',
        Account: 'rMultisigAccount…',
        Destination: 'r…',
        Amount: '1000000',
        Fee: '36',
        Sequence: 42,
        SigningPubKey: '',
      },
    },
  },
  'xrpl:0',
);

Set Fee and Sequence yourself so every signer signs identical bytes. LastLedgerSequence is optional, which allows ticket-based multisign.

#Refused requests

An XLS-56 Batch is handled as a batch co-signature instead, and these checks don't apply to it.

#Response

{ tx_json: { hash: string; Signers: [/* …with this account's entry added */]; /* … */ } }

#With wc-client

import core from '@joey-wallet/wc-client/core';

const response = await core.methods.signTransactionFor({
  provider,
  chainId: chain,
  request: {
    tx_signer: connectedAddress,
    tx_json: {
      TransactionType: 'Payment',
      Account: 'rMultisigAccount…',
      Destination: 'r…',
      Amount: '1000000',
      Fee: '36',
      Sequence: 42,
      SigningPubKey: '',
    },
  },
});
