depositTransaction

Initiates a deposit transaction on an L1, which executes a transaction on an L2.

Internally performs a contract write to the depositTransaction function on the Optimism Portal contract.

Usage

example.ts
import { base } from 'viem/chains'
import { account, walletClientL1 } from './config'
 
const hash = await walletClientL1.depositTransacton({
  account,
  request: {
    gas: 21_000n,
    mint: parseEther('1')
    to: '0x70997970c51812dc3a010c7d01b50e0d17dc79c8',
  },
  targetChain: base,
})

Building Parameters

The buildDepositTransaction Action builds & prepares the deposit transaction parameters (ie. gas, targetChain, etc).

We can use the resulting args to initiate the deposit transaction on the L1.

example.ts
import { account, publicClientL2, walletClientL1 } from './config'
 
// Build parameters for the transaction on the L2.
const args = await publicClientL2.buildDepositTransaction({
  account,
  mint: parseEther('1')
  to: '0x70997970c51812dc3a010c7d01b50e0d17dc79c8',
})
 
// Execute the deposit transaction on the L1.
const hash = await walletClientL1.depositTransacton(args)

See more on the buildDepositTransaction Action.

Account Hoisting

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

example.ts
import { publicClientL2, walletClientL1 } from './config'
 
// Prepare parameters for the deposit transaction on the L2.
const args = await publicClientL2.buildDepositTransaction({
  mint: parseEther('1')
  to: '0x70997970c51812dc3a010c7d01b50e0d17dc79c8',
})
 
// Initiate the deposit transaction on the L1.
const hash = await walletClientL1.depositTransacton(args)

Returns

Hash

The L1 Transaction hash.
