@turnkey/viem

This package contains helpers to work with Turnkey. Currently:

• a Turnkey Custom Account (signer)

If you need a lower-level, fully typed HTTP client for interacting with Turnkey API, check out @turnkey/http.

Getting started

$ npm install viem @turnkey/viem

import { createWalletClient, http } from "viem";
import { createAccount } from "@turnkey/viem";

async function main() {
  const turnkeyAccount = createAccount({
    organizationId: "...",
    privateKeyId: "...",
    apiPublicKey: "...",
    apiPrivateKey: "...",
    baseUrl: "https://api.turnkey.com",
  });

  const client = createWalletClient({
    account: turnkeyAccount,
    chain: sepolia,
    transport: http(`https://sepolia.infura.io/v3/$(YOUR_INFURA_API_KEY)`),
  });

  const transactionRequest = {
    to: "0x08d2b0a37F869FF76BACB5Bab3278E26ab7067B7" as `0x${string}`,
    value: 1000000000000000n, // 0.001 ETH
  };

  const txHash = await client.sendTransaction(transactionRequest);
  console.log(`Success! Transaction broadcast with hash ${txHash}`);
}

main().catch((error) => {
  console.error(error);
  process.exit(1);
});
