Code Example for Contract Deposit

This section provides example implementations for calling the deposit() function on the v1 Deposit Contracts.

The Contract Deposit method is maintained for existing integrations, but new implementations should use the Direct Deposit method.

Supported Chains and Contract Addresses

For a comprehensive list of all supported chains and their respective contract addresses for v1 contract deposits, please refer to the Contract Deposit Supported Chains section.

Implementation Examples

The following code snippets demonstrate how to interact with the deposit() function across various programming languages and libraries:

viem

import { parseEther, http, createWalletClient, publicActions } from 'viem'
import { privateKeyToAccount } from 'viem/accounts'
import { optimism } from 'viem/chains'
import { depositABI } from './depositABI'
 
// Create a wallet from a private key
const account = privateKeyToAccount('0x...')
 
// Connect the wallet to a provider
const client = createWalletClient({
  account,
  chain: optimism, // Target Chain
  transport: http(),
}).extend(publicActions)
 
// Replace with address you want to send funds to
const toAddress = account.address
 
// Each chain will receive an equal portion of the value sent
const amount: bigint = parseEther('0.0006')
 
// This example is targeting zkSync (51), Polygon zkEVM (52) - These are Gas.zip short chain IDs
const gasZipShortChainIDs = [51, 52]
 
// Prepare targeted chains parameter for deposit()
const chainsBN = gasZipShortChainIDs.reduce((p, c) => (p << BigInt(8)) + BigInt(c), BigInt(0))
 
;(async () => {
  // Prepare the contract write configuration
  const { request } = await client.simulateContract({
    address: '0x9e22ebec84c7e4c4bd6d4ae7ff6f4d436d6d8390', // Targeting Gas.zip Optimism Contract
    abi: depositABI,
    functionName: 'deposit',
    value: amount,
    args: [chainsBN, toAddress],
  })
 
  // Call the deposit() function
  await client.writeContract(request)
})()
