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";
let myVaults = getVaults("0x123456", signer);
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:
