Signing Transactions

This is a guide to signing transactions in a server context. While these snippets leverage Ethers, it can be swapped out for other signers in the Viem or Solana contexts. An example for Ethers can be found , and for Viem in the server context. A similar example with Solana can be found .

1. Initialize the Server Client

   import { Turnkey } from "@turnkey/sdk-server";
   
   const turnkeyClient = new Turnkey({
     apiBaseUrl: "https://api.turnkey.com",
     defaultOrganizationId: process.env.TURNKEY_ORGANIZATION_ID,
     apiPrivateKey: process.env.API_PRIVATE_KEY,
     apiPublicKey: process.env.API_PUBLIC_KEY,
   });
   
2. Initialize an Ethers Provider and Turnkey Signer

   import { ethers } from "ethers";
   import { TurnkeySigner } from "@turnkey/ethers";
   
   const provider = new ethers.JsonRpcProvider(<provider api url>);
   const turnkeySigner = new TurnkeySigner({
       client: turnkeyClient.apiClient(),
       organizationId: process.env.ORGANIZATION_ID!,
       signWith: process.env.SIGN_WITH!,
     });
   
3. Call `sendTransaction` with the Turnkey Signer

   const transactionRequest = {
     to: "<destination address>",
     value: ethers.parseEther("<amount to send>"),
     type: 2,
   };
   const sendTransaction =
     await connectedSigner.sendTransaction(transactionRequest);
