sendTransaction

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

Usage

example.ts
import { account, walletClient } from './config'
 
const hash = await walletClient.sendTransaction({ 
  account,
  to: '0x70997970c51812dc3a010c7d01b50e0d17dc79c8',
  value: 1000000000000000000n
})
// '0x...'

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).

Hash

The Transaction hash.

  to: '0x70997970c51812dc3a010c7d01b50e0d17dc79c8',
  value: 1000000000000000000n
})

to

  • Type: 0x${string}

The transaction recipient or contract address.

const hash = await walletClient.sendTransaction({
  account,
  to: '0x70997970c51812dc3a010c7d01b50e0d17dc79c8', 
  value: 1000000000000000000n,
  nonce: 69
})

accessList (optional)

The access list.

const hash = await walletClient.sendTransaction({
  accessList: [

const authorization = await walletClient.signAuthorization({ 
  account,
  contractAddress: '0xFBA3912Ca04dd458c843e2EE08967fC04f3579c2', 
}) 
 
const hash = await walletClient.sendTransaction({
  account,
  authorizationList: [authorization], 
  data: '0xdeadbeef',
  to: account.address,
})

blobs (optional)

  • Type: Hex[]

Blobs for Blob Transactions.

import * as kzg from 'c-kzg'
import { toBlobs, stringToHex } from 'viem'
import { mainnetTrustedSetupPath } from 'viem/node'
 
const kzg = setupKzg(cKzg, mainnetTrustedSetupPath) 
 
const hash = await walletClient.sendTransaction({
  account,

import { optimism } from 'viem/chains'
 
const hash = await walletClient.sendTransaction({
  chain: optimism, 
  account,
  to: '0x70997970c51812dc3a010c7d01b50e0d17dc79c8',

const kzg = setupKzg(cKzg, mainnetTrustedSetupPath) 
 
const hash = await walletClient.sendTransaction({
  account,
  blobs: toBlobs({ data: stringToHex('blobby blob!') }), 
  kzg, 
  to: '0x70997970c51812dc3a010c7d01b50e0d17dc79c8'

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 via getAddresses
