# Sign Transaction \[signTransaction]

Signs a transaction. Alias of [`Actions.transaction.sign`](/docs/actions/wallet/transaction/sign).

## Usage

This example signs a transaction.

:::code-group
```ts twoslash [example.ts]
import { client } from './viem.config'

const signed = await client.signTransaction({
  to: '0x70997970c51812dc3a010c7d01b50e0d17dc79c8',
  value: 1n,
})
// @log: '0x02f86b0180843b9aca008502540be400825208...'
```

```ts twoslash [viem.config.ts] filename="viem.config.ts"
import { Account, Client, http, walletActions } from 'viem'
import { mainnet } from 'viem/chains'

export const client = Client.create({
  account: Account.fromPrivateKey('0x…'),
  chain: mainnet,
  transport: http(),
}).extend(walletActions())
```

### Standalone Action

Call `Actions.signTransaction` directly by passing the Client as the first argument.

```ts twoslash [example.ts]
import { Actions } from 'viem'
import { client } from './viem.config'

const signed = await Actions.signTransaction(client, {
  to: '0x70997970c51812dc3a010c7d01b50e0d17dc79c8',
  value: 1n,
})
// @log: '0x02f86b0180843b9aca008502540be400825208...'
```

```ts twoslash [viem.config.ts] filename="viem.config.ts"
import { Account, Client, http } from 'viem'
import { mainnet } from 'viem/chains'
