How to use the faucet
Once you're registered ↗ and have an API key ↗ set up on the Chainstack platform, you can get up to 0.5 Sepolia ETH every 24 hours. Testnet ETH can be used to send transaction on the Sepolia testnet, deploy your smart contracts, and test their different functions before deploying them on a mainnet, that involves real funds.
For a step-by-step tutorial on how to request funds from our Sepolia faucet, watch the video demo below.
Why do I need ETH on Mainnet in order to request funds from the faucet?
This measure helps ensure fair usage and prevents exploitation of the service. Our faucet requires you to hold 0.002 ETH in your Ethereum Mainnet wallet, in order to use it. If you feel like you have been flagged erroneously, contact us on Telegram ↗ or Discord ↗.
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 after 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 restricted the maximum amount of Sepolia testnet tokens you can request to up to 0.5 ETH a 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 testnet tokens 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.

What is Chainstack?
Chainstack is the limitless Web3 development stack for Web3 developers. Every blockchain, Every API, every tool that you need to build applications for any 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 Sepolia testnet ETH to test your smart contracts before deploying them to production.
What is the Sepolia testnet?
Sepolia is one of the two public Ethereum testnets, the other one being Goerli. Sepolia is the default recommended testnet for Ethereum DApp developers. It's perfect for contract and application developers to test their applications before deploying them live.
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 0.5 Sepolia Testnet ETH daily.
What are Sepolia testnet Ethereum token?
A Sepolia testnet Ethereum token is the gas fee token for the Sepolia 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 Sepolia testnet, and interact with those contracts through transactions.
