Ethereum: Deploy a contract to Ethereum via zkSync?

Posted on by chang mr.

Deploying a contract on Ethereum using zk-Sync

When you deploy a smart contract on Ethereum via zk-Sync, you don’t directly get an Ethereum contract address. Instead, you create a bridge between your local Ethereum network and the Ethereum mainnet via zk-Sync.

Here’s what happens behind the scenes:

  • zk-Sync: Zk-Sync is a layer 2 scaling solution for Ethereum that enables faster and more reliable transactions by offloading some of the computation from the Ethereum blockchain to a secondary network called zksync.com.
  • Creating a bridge: When you deploy a zk-Sync contract, you create a bridge between your local Ethereum network (e.g. via Web3.py or Truffle) and the Ethereum mainnet (Ethereum.org).
  • Getting the contract address: Once the bridge is created, you can retrieve the Ethereum contract address associated with your smart contract.

However, deploying to zk-Sync does not directly give you an Ethereum contract address. Instead, it provides a way to interact with your contract on the Ethereum mainnet using Web3.js or similar libraries.

Why does this matter?

Deploying to zk-Sync may seem like a convenient way to bridge the gap between your local and Ethereum networks, but it has some important implications:

  • Ownership: When you deploy a contract to zk-Sync, you still own it. If you want to withdraw funds from the contract, you will need to transfer them to the Ethereum network using Web3.js.
  • Gas fees

    : Deploying to zk-Sync may incur additional gas fees due to its complexity.

Example code

Here is a simple JavaScript example using Truffle and Web3.js:

const Web3 = require('web3');
const truffle = require('truffle');
// Create a new Web3 instance
const web3 = new Web3(new Web3.providers.HttpProvider('
// Deploy your contract in zk-Sync
truffle.deploy('YourContractAddress', 'YourContractKey')
.then((contract) => {
// Get the Ethereum contract address associated with your smart contract
const ethereumContractAddress = contract.address;
console.log(ethereumContractAddress);
})
.catch((error) => {
console.error(error);
});

In this example, “YourContractAddress” and “yourContractabikey” are placeholders for the actual Ethereum contract address and ABI key. You need to replace them with the correct values.

Conclusion

While deploying a contract on zk-Sync may seem like a convenient way to bridge the gap between your local and Ethereum networks, it’s important to understand that you’re not directly getting an Ethereum contract address. Instead, you’re creating a bridge that allows you to interact with a smart contract on the Ethereum mainnet using Web3.js.

Be sure to carefully review the implications of deploying zk-Sync and plan accordingly. Happy coding!
