sendTransaction
Creates, signs, and sends a new transaction to the network.
Usage
import { account, walletClient } from './config'
const hash = await walletClient.sendTransaction({
account,
to: '0x70997970c51812dc3a010c7d01b50e0d17dc79c8',
value: 1000000000000000000n
})
// '0x...'
import { createWalletClient, custom } from 'viem'
import { privateKeyToAccount } from 'viem/accounts'
import { mainnet } from 'viem/chains'
export const walletClient = createWalletClient({
chain: mainnet,
transport: custom(window.ethereum)
})
// JSON-RPC Account
export const [account] = await walletClient.getAddresses()
// Local Account
export const account = privateKeyToAccount(...)
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).
import { walletClient } from './config'
const hash = await walletClient.sendTransaction({
to: '0x70997970c51812dc3a010c7d01b50e0d17dc79c8',
value: 1000000000000000000n
})
// '0x...'
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)
})
import { createWalletClient, custom } from 'viem'
import { privateKeyToAccount } from 'viem/accounts'
export const walletClient = createWalletClient({
account: privateKeyToAccount('0x...'),
transport: custom(window.ethereum)
})
Returns
The Transaction hash.

to
- Type:
number

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). You can also check if the user has granted access to their accounts viagetAddresses
