Create a new project:

```bash
mkdir zerodev
cd zerodev
npm init -y
```

Install the ZeroDev SDK and a plugin:

<Tabs items="[&#x22;npm&#x22;,&#x22;yarn&#x22;,&#x22;pnpm&#x22;,&#x22;bun&#x22;]">
  <Tab value="npm">
    ```bash
    npm i @zerodev/sdk @zerodev/ecdsa-validator
    ```
  </Tab>

  <Tab value="yarn">
    ```bash
    yarn add @zerodev/sdk @zerodev/ecdsa-validator
    ```
  </Tab>

  <Tab value="pnpm">
    ```bash
    pnpm add @zerodev/sdk @zerodev/ecdsa-validator
    ```
  </Tab>

  <Tab value="bun">
    ```bash
    bun add @zerodev/sdk @zerodev/ecdsa-validator
    ```
  </Tab>
</Tabs>

Install dev packages for TypeScript:

<Tabs items="[&#x22;npm&#x22;,&#x22;yarn&#x22;,&#x22;pnpm&#x22;,&#x22;bun&#x22;]">
  <Tab value="npm">
    ```bash
    npm i -D @types/node tslib
    ```
  </Tab>

  <Tab value="yarn">
    ```bash
    yarn add -D @types/node tslib
    ```
  </Tab>

  <Tab value="pnpm">
    ```bash
    pnpm add -D @types/node tslib
    ```
  </Tab>

  <Tab value="bun">
    ```bash
    bun add -d @types/node tslib
    ```
  </Tab>
</Tabs>

Create the following `tsconfig.json` (TypeScript config):

```json
{
  "compilerOptions": {
    "target": "es5",
    "module": "commonjs",
    "declaration": true,
    "outDir": "./lib",
    "strict": true,
    "esModuleInterop": true
  },
  "include": ["./**/*.ts"]
}
```

Create a script `index.ts` with the following code:

```ts
import { createKernelAccount, createKernelAccountClient, createZeroDevPaymasterClient } from "@zerodev/sdk"
import { KERNEL_V3_1, getEntryPoint } from "@zerodev/sdk/constants"
import { signerToEcdsaValidator } from "@zerodev/ecdsa-validator"
import { http, createPublicClient, zeroAddress } from "viem"
import { generatePrivateKey, privateKeyToAccount } from "viem/accounts"
import { baseSepolia } from "viem/chains"
 
const ZERODEV_RPC = 'https://rpc.zerodev.app/api/v3/61016d2a-e0df-4350-929c-d5f2110700d1/chain/84532'

const chain = baseSepolia 
const entryPoint = getEntryPoint("0.7")
const kernelVersion = KERNEL_V3_1
 
const main = async () => {
  // Construct a signer
  const privateKey = generatePrivateKey()
  const signer = privateKeyToAccount(privateKey)
 
  // Construct a public client
  const publicClient = createPublicClient({
    // Use your own RPC provider in production (e.g. Infura/Alchemy).
    transport: http(ZERODEV_RPC),
    chain
  })
 
  // Construct a validator
  const ecdsaValidator = await signerToEcdsaValidator(publicClient, {
    signer,
    entryPoint,
    kernelVersion
  })
 
  // Construct a Kernel account
  const account = await createKernelAccount(publicClient, {
    plugins: {
      sudo: ecdsaValidator,
    },
    entryPoint,
    kernelVersion
  })
 
  const zerodevPaymaster = createZeroDevPaymasterClient({
    chain,
    transport: http(ZERODEV_RPC),
  })
 
  // Construct a Kernel account client
  const kernelClient = createKernelAccountClient({
    account,
    chain,
    bundlerTransport: http(ZERODEV_RPC),
    // Required - the public client
    client: publicClient,
    paymaster: {
        getPaymasterData(userOperation) {
            return zerodevPaymaster.sponsorUserOperation({userOperation})
        }
    },
  })
 
  const accountAddress = kernelClient.account.address
  console.log("My account:", accountAddress)
 
  // Send a UserOp
  const userOpHash = await kernelClient.sendUserOperation({
      callData: await kernelClient.account.encodeCalls([{
        to: zeroAddress,
        value: BigInt(0),
        data: "0x",
      }]),
  })
 
  console.log("UserOp hash:", userOpHash)
  console.log("Waiting for UserOp to complete...")
 
  await kernelClient.waitForUserOperationReceipt({
    hash: userOpHash,
    timeout: 1000 * 15,
  })
 
  console.log("UserOp completed: https://base-sepolia.blockscout.com/op/" + userOpHash)
 
  process.exit()
}
 
main()
```

Run it:

```bash
npx ts-node index.ts
```

You should see an output like this:

```txt
My account: 0xaf731E22Fe96979C5D864B07bad0EB999cDBbE76
UserOp hash: 0x7a8e0ba961cc0a34f745b81d64766f033269fee831104fee0269fa5bcc397dcb

```

Congrats -- you just sent your first gasless transaction with ZeroDev!

In this example, you used a public ZeroDev API key.  Now read [Set up a project](/get-started/sdks/setup-project) to see how to set up your own ZeroDev project, then walk through the full [TypeScript / JavaScript tutorial](/get-started/sdks/client-side/typescript).
