Wallet Daemon Signer

WalletDaemonSigner implements the Signer interface by delegating all cryptographic operations to a running tari_ootle_walletd process via @tari-project/wallet_jrpc_client. The secret key never enters JavaScript memory.

Setup

Start the wallet daemon:

./tari_ootle_walletd --network esme

Connect

import { WalletDaemonSigner } from "@tari-project/ootle-wallet-daemon-signer";

const signer = await WalletDaemonSigner.connect({
  url: "http://localhost:18103",
  authToken: "your-auth-token",
});

connect() reaches out to the daemon, fetches the default account’s public key and address, and caches them.

Use

// Cached — no network call
const address = await signer.getAddress();
const publicKey = await signer.getPublicKey();

// Signs via the daemon — the key stays on the daemon
const signatures = await signer.signTransaction(unsignedTx);

Full example

import { TransactionBuilder, sendTransaction, Network } from "@tari-project/ootle";
import { ProviderBuilder } from "@tari-project/ootle-indexer";
import { WalletDaemonSigner } from "@tari-project/ootle-wallet-daemon-signer";

const provider = await ProviderBuilder.new()
  .withNetwork(Network.LocalNet)
  .connect();

const signer = await WalletDaemonSigner.connect({
  url: "http://localhost:18103",
  authToken: "your-auth-token",
});

const accountAddress = await signer.getAddress();

const unsignedTx = TransactionBuilder.new(Network.LocalNet)
  .feeTransactionPayFromComponent(accountAddress, 1000n)
  .callMethod(
    { componentAddress: accountAddress, methodName: "withdraw" },
    [{ Literal: resourceAddress }, { Literal: "10" }],
  )
  .saveVar("bucket")
  .callMethod(
    { componentAddress: accountAddress, methodName: "deposit" },
    [{ Workspace: "bucket" }],
  )
  .buildUnsignedTransaction();

const result = await sendTransaction(provider, signer, unsignedTx);
