Need Sepolia ETH for Testing Smart Contracts

[shopiMarvels]

Hey everyone! 👋

I’m currently working on Solidity development and need some Sepolia ETH to deploy and test smart contracts on the Sepolia Testnet. Unfortunately, the faucets I’ve tried (Infura, Chainlink) require Ethereum Mainnet history or LINK, which I don’t have.

If anyone has extra Sepolia ETH, I’d really appreciate a small amount to my wallet: 0x5219477Db0EdC5C3C7a6fc1211919360272E99B6 🙏.

Thanks in advance! Happy to pay it forward once I have some. 🚀

This is a real bummer for me too.
I have not found a way to get unlimited free Sepolia myself but have come across websites that don't have this prerequisite:

Optimism faucet: https://console.optimism.io/faucet
Google cloud faucet: https://cloud.google.com/application/web3/faucet/ethereum/sepolia

They have daily limit to Sepolia Ethereum but hey, at least it doesn't require Mainnet link.

That Worked Thanks a lot!

Thanks for the optimism one! I only knew about Google cloud and it only gave .05 ETH :(

@shopiMarvels feel free to mark the above as answer, since this discussion is still marked as unanswered!

These are some other free faucets which also refresh periodically:

Higly helpful, Thanks!

So guys I have a conclusion to this. These faucets aren't enough for testing purposes, let alone deployment.

What instead you can do is use Ganache locally and connect metamask to it.
Try this out and this will fix your problem completely:

[JohnRTitor]

Yeah, but since these are local networks, I don't think any oracle is monitoring these. So to make API calls to an address on sepolia testnet for example, it won't work.

[falgunxd]

yeah, this is just for testing out the contracts, not for deployment.

What instead you can do is use Ganache locally and connect metamask to it.

Patrick even shows how to set it up. But given the current state of ganache (it is deprecated), the best you can have is a local Blockchain node running on Hardhat (hardhat node). Patrick also showcased the procedure.

Understanding the Sepolia Testnet
Sepolia is one of the Ethereum network’s official testnets, specifically designed for developers to experiment with dApps and smart contracts without using real ETH. As a proof-of-stake testnet, Sepolia closely mirrors Ethereum’s mainnet environment, making it ideal for pre-deployment testing. Developers can simulate smart contract interactions, gas consumption, and edge cases in a safe, cost-free sandbox.

Unlike older testnets like Rinkeby or Ropsten, Sepolia is maintained by the Ethereum Foundation and is more compatible with Ethereum's latest upgrades, including the Merge and EIP changes. This makes it the go-to network for testing scalable and secure smart contracts.

Importance for Developers and Businesses
Access to Sepolia ETH allows developers to test smart contract logic, security, and gas optimization before deploying on the mainnet, reducing the risk of financial loss or contract failure. For companies offering smart contract development services, Sepolia enables teams to demonstrate contract functionality to clients, conduct third-party audits, and fine-tune performance—all without spending real ETH.

To get Sepolia ETH, developers can use faucets like Alchemy or Chainlink's Sepolia faucet, often requiring a GitHub login. It’s a foundational tool for anyone committed to building secure, reliable blockchain applications.
