zkSync Faucet – Claim Free zkSync ETH

Introducing the zkSync Testnet Faucet: Your Gateway to Testnet ETH.

In the world of Web3 development, you will always need testnet tokens. Whether you’re experimenting with smart contracts, building decentralized applications, or refining your blockchain solutions, access to testnet tokens is necessary. We understand the challenges and frustrations that developers face when building DApps. That’s why we created the zkSync Testnet Faucet, designed with Web3 developers like you in mind.

How to use the zkSync faucet

Once you’re registered ↗ and have an API key ↗ set up on the Chainstack platform, you can get up to 0.05 zkSync ETH every 24 hours. This ETH can be used to send transaction on the zkSync testnet, deploy your smart contracts, and test their different functions before pushing them to mainnet, which involves real funds.

For a step-by-step tutorial on how to request ETH from our zkSync faucet, watch the video demo below:

Why do I need Mainnet ETH in order to request funds from the faucet?

Our faucet requires you to hold 0.002 ETH in your wallet on the Ethereum Mainnet, in order to use it. This measure helps ensure a fair usage and prevents exploitation of the faucet.

Why does it take so much time for my tokens to arrive?

Usually, the process of receiving your tokens should be fast, but sometimes the network may be congested and you might need to wait a little while. If you do not get your tokens within 15 minutes, please contact us on Telegram or Discord.

I get an error saying “The user can only receive funds every 24 hours.”

In order to ensure an even distribution across the Ethereum developer community, we have capped the maximum amount of zkSync ETH that you can request to a maximum of 0.05 per day.

I get an error saying “Something went wrong. Check credentials and try again.”

You might’ve entered an incorrect API key or wallet address. Please check them again, refresh the page, and try one more time.

In order to generate your API key, you will need to sign-up via the Chainstack console first. Check out the video above to see how to generate your own API key and request zkSync testnet ETH from the faucet.

If you are sure that the API key is valid, your wallet address is correct, and you still can not claim tokens, you can contact us on Telegram or Discord so we can assist you.

Do you need help when using the faucet?

You can contact us via Telegram or Discord and one of our team members will help you to get testnet tokens.

Now that I have my funds, what shall I do next?

Tell us about the DApp that you are building and tag our @ChainstackHQ X (Twitter) account in your post. We would like to learn more about your DApp.

I want the best zkSync nodes

If you are looking for fast and reliable zkSync nodes, you can sign-up on Chainstack and deploy one for free. We support over 20 different blockchains, and we also provide additional developer tooling.

What is Chainstack?

Chainstack is the limitless Web3 development stack for Web3 developers. Every protocol, every API, every tool that you’ll ever need to build any DApp at scale.

Where can I learn to build DApps?

Our Web3 documentation is the perfect place to get you started. You will find everything you need in there from smart contract tutorials to APIs, and recipes. Let’s get you started with this quick glossary:

What is a faucet?

A faucet is a developer tool that gives you testnet tokens to use when testing your smart contracts or interacting with DApps on test networks. The Chainstack faucet gives you zkSync testnet ETH to test your smart contracts before pushing them to production.

What is the zkSync testnet?

According to zkSync themselves “zkSync is a Zero Knowledge (ZK) rollup that supports generalized EVM compatibility for the Ethereum blockchain. The primary benefit of zkSync Era is that developers who have created EVM dApps can port to zkSync Era effortlessly and realize significantly lower gas fees and more transactions per second while inheriting Ethereum’s security and decentralization.”

The testnet is therefore a playground for developers, where you can test your DApps and make sure all the functions work as intended, before pushing them to production.

What is the meaning of drip?

When it comes to Web3 faucets, the drip refers to the amount of testnet tokens that you can get from a faucet each day. In your case, this would be 0.05 zkSync ETH daily.

What are zkSync testnet Ethereum tokens?

A zkSync testnet Ethereum token is the gas fee token for the zkSync testnet. Testnet tokens do not have real monetary value (these tokens are not like the “real” Ethereum), but they play an important role in covering gas costs. You will need them in order to deploy your smart contracts on the zkSync testnet, and interact with those contracts through transactions.
