# Company Wallets quickstart
> Get from zero to a signed transaction with Turnkey's Company Wallets. Initialize the server SDK, create a wallet, and sign your first Ethereum transaction using Viem or Ethers.

## Prerequisites
This guide assumes you've completed the steps to create an account, organization, and API keypair as described in the [account setup](/get-started/quickstart) section. This guide uses the TypeScript server SDK (`@turnkey/sdk-server`). For other languages, see [Server SDKs](/sdks/introduction).
## Installation
Install the server SDK and your preferred Ethereum library:
```bash Viem theme={"system"}
npm install @turnkey/sdk-server @turnkey/viem viem
```
```bash Ethers theme={"system"}
npm install @turnkey/sdk-server @turnkey/ethers ethers
```
This quickstart uses Ethereum, but Turnkey supports all EVM and SVM chains, along with Bitcoin, Tron, and [more](/features/networks/overview). To sign Solana transactions, derive a Solana address using `ADDRESS_FORMAT_SOLANA` with `CURVE_ED25519` and use [`@turnkey/solana`](https://www.npmjs.com/package/@turnkey/solana) or the server SDK's [`solSendTransaction`](/features/networks/solana) method.
## Sign your first transaction
Add your API credentials to a `.env` file:
```bash theme={"system"}
TURNKEY_ORGANIZATION_ID=
TURNKEY_API_PRIVATE_KEY=
TURNKEY_API_PUBLIC_KEY=
```
Then initialize the client in your application:
```ts theme={"system"}
import { Turnkey } from "@turnkey/sdk-server";
const turnkeyClient = new Turnkey({
apiBaseUrl: "https://api.turnkey.com",
defaultOrganizationId: process.env.TURNKEY_ORGANIZATION_ID!,
apiPrivateKey: process.env.TURNKEY_API_PRIVATE_KEY!,
apiPublicKey: process.env.TURNKEY_API_PUBLIC_KEY!,
});
```
Create a wallet and derive an Ethereum address in a single call:
```ts theme={"system"}
const { walletId, addresses } = await turnkeyClient.apiClient().createWallet({
walletName: "default",
accounts: [
{
curve: "CURVE_SECP256K1",
pathFormat: "PATH_FORMAT_BIP32",
path: "m/44'/60'/0'/0/0",
addressFormat: "ADDRESS_FORMAT_ETHEREUM",
},
],
});
const ethereumAddress = addresses[0];
console.log("Ethereum address:", ethereumAddress);
```
```ts theme={"system"}
import { createAccount } from "@turnkey/viem";
import { createWalletClient, http } from "viem";
import { mainnet } from "viem/chains";
const turnkeyAccount = await createAccount({
client: turnkeyClient.apiClient(),
organizationId: process.env.TURNKEY_ORGANIZATION_ID!,
signWith: ethereumAddress,
});
const walletClient = createWalletClient({
account: turnkeyAccount,
chain: mainnet,
transport: http(),
});
```
```ts theme={"system"}
import { ethers } from "ethers";
import { TurnkeySigner } from "@turnkey/ethers";
const provider = new ethers.JsonRpcProvider("YOUR_RPC_URL");
const turnkeySigner = new TurnkeySigner({
client: turnkeyClient.apiClient(),
organizationId: process.env.TURNKEY_ORGANIZATION_ID!,
signWith: ethereumAddress,
});
const connectedSigner = turnkeySigner.connect(provider);
```
```ts theme={"system"}
import { parseEther } from "viem";
const txHash = await walletClient.sendTransaction({
to: "",
value: parseEther(""),
});
console.log("Transaction hash:", txHash);
```
```ts theme={"system"}
const txHash = await connectedSigner.sendTransaction({
to: "",
value: ethers.parseEther(""),
type: 2,
});
console.log("Transaction hash:", txHash.hash);
```
