# sendTransaction

Creates, signs, and sends a new transaction to the network.

## Usage

:::code-group
```ts twoslash [example.ts]
import { account, walletClient } from './config'
 
const hash = await walletClient.sendTransaction({ // [!code focus:99]
  account,
  to: '0x70997970c51812dc3a010c7d01b50e0d17dc79c8',
  value: 1000000000000000000n
})
// '0x...'
```

```ts twoslash [config.ts] filename="config.ts"
// [!include ~/snippets/walletClient.ts]

export const [account] = await walletClient.getAddresses()
// @log: ↑ JSON-RPC Account

// export const account = privateKeyToAccount(...)
// @log: ↑ Local Account
```
:::

### Account Hoisting

If you do not wish to pass an `account` to every `sendTransaction`, you can also hoist the Account on the Wallet Client (see `config.ts`).

[Learn more](/docs/clients/wallet#account).

:::code-group
```ts twoslash [example.ts]
import { walletClient } from './config'
 
const hash = await walletClient.sendTransaction({ // [!code focus:99]
  to: '0x70997970c51812dc3a010c7d01b50e0d17dc79c8',
  value: 1000000000000000000n
})
// '0x...'
```

```ts [config.ts (JSON-RPC Account)]
import { createWalletClient, custom } from 'viem'

// Retrieve Account from an EIP-1193 Provider.
const [account] = await window.ethereum.request({ 
  method: 'eth_requestAccounts' 
})

export const walletClient = createWalletClient({
  account,
  transport: custom(window.ethereum!)
})
```

```ts twoslash [config.ts (Local Account)] filename="config.ts"
import { createWalletClient, http } from 'viem'
import { privateKeyToAccount } from 'viem/accounts'

export const walletClient = createWalletClient({
  account: privateKeyToAccount('0x...'),
  transport: http()
})
```

## Returns

[`Hash`](/docs/glossary/types#hash)

The [Transaction](/docs/glossary/terms#transaction) hash.

## Parameters

    },
  ],
  account,
  to: '0x70997970c51812dc3a010c7d01b50e0d17dc79c8',
})
```

### authorizationList (optional)

* **Type:** `AuthorizationList`

## Tips

* For dapps: When using this action, it is assumed that the user has connected to their wallet (e.g. given permission for the dapp to access their accounts via [`requestAddresses`](/docs/actions/wallet/requestAddresses)). You can also check if the user has granted access to their accounts via [`getAddresses`](/docs/actions/wallet/getAddresses)
