Parameters
from
- Type:
Address
The Transaction sender.
const hash = await walletClient.sendTransaction({
from: '0xf39fd6e51aad88f6f4ce6ab8827279cfffb92266',
to: '0x70997970c51812dc3a010c7d01b50e0d17dc79c8',
value: 1000000000000000000n
})
to
- Type:
number
The transaction recipient or contract address.
const hash = await walletClient.sendTransaction({
from: '0xf39fd6e51aad88f6f4ce6ab8827279cfffb92266',
to: '0x70997970c51812dc3a010c7d01b50e0d17dc79c8',
value: 1000000000000000000n,
nonce: 69
})
accessList (optional)
- Type:
AccessList
The access list.
const data = await publicClient.sendTransaction({
accessList: [
{
address: '0x1',
storageKeys: ['0x1'],
},
],
from: '0xf39fd6e51aad88f6f4ce6ab8827279cfffb92266',
to: '0x70997970c51812dc3a010c7d01b50e0d17dc79c8',
})
assertChain (optional)
- Type:
boolean - Default:
true
Throws an error if chain does not match the current wallet chain.
Defaults to true, but you can turn this off if your dapp is primarily multi-chain.
import { optimism } from 'viem/chains'
const hash = await walletClient.sendTransaction({
assertChain: false,
chain: optimism,
from: '0xf39fd6e51aad88f6f4ce6ab8827279cfffb92266',
to: '0x70997970c51812dc3a010c7d01b50e0d17dc79c8',
value: 1000000000000000000n
})
chain (optional)
- Type:
Chain
The target chain. If there is a mismatch between the wallet's current chain & the target chain, an error will be thrown if assertChain is truthy.
The chain is also used to infer its request type (e.g. the Celo chain has a gatewayFee that you can pass through to sendTransaction).
import { optimism } from 'viem/chains'
const hash = await walletClient.sendTransaction({
chain: optimism,
from: '0xf39fd6e51aad88f6f4ce6ab8827279cfffb92266',
to: '0x70997970c51812dc3a010c7d01b50e0d17dc79c8',
value: 1000000000000000000n
})

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
requestAccounts). You can also check if the user has granted access to accounts viagetAccounts
