signTx

---

A user can sign a proposed transaction with their keyshare

This allows us to send a transaction that has been voted on (a signature of the transaction = a vote in our case) by a > threshold participants.

This function needs the person to gather some data from the smart contract to pass to it.

import { signTx, getVaults } from "@intuweb3/web-exp";
let myVaults = getVaults("0x12345_user_address", provider);
let vaultaddress = myVaults[i].vaultAddress;
let transactions = myVaults[i].transactions;
let txId = //the ID of the transaction you want to sign. NOT the index of the transaction, the ID.
  await signTx(vaultAddress, txId, signer);

Arguments:

Input	Type of Input	Description
vaultAddress	String	User signed vault message
txId	Number	Id of the transaction, identified from the transactions array in getVaults
signer	object	Signer object from ethers

The result of this needs to be stored in the smart contract. This happens automatically!

Output	Type of Output	Description
signedTxForStorage	String	This is a signed transaction for a single participant. To be combined with other participant's signatures once threshold is reached.

Returns:

signedTxForStorage

String of signed transaction, encoded in base64 for storage:
