Ethereum testnets are essential tools for developers building decentralized applications (dApps) and smart contracts. These simulated environments mirror the Ethereum mainnet, allowing developers to test functionality, security, and user experience without risking real funds. A key component of any testnet is the faucet—a service that distributes free test Ether (ETH) to users. In this guide, we’ll explore the most reliable and up-to-date Ethereum testnet faucets for Goerli and Sepolia, two of the most widely used test networks in 2025.
Whether you're a developer testing a new DeFi protocol or a user exploring dApp interactions, having access to test ETH is crucial. We'll also cover how to use these faucets effectively, what requirements they have, and tips to maximize your test token allocation.
Understanding Ethereum Testnets
Before diving into faucet options, it’s important to understand the role of Ethereum testnets in the blockchain ecosystem.
Testnets replicate the Ethereum mainnet environment but use non-valuable ETH tokens for testing purposes. This allows developers to:
- Deploy and debug smart contracts
- Simulate real-world transaction scenarios
- Test wallet integrations and front-end interfaces
- Participate in potential airdrops by interacting with early-stage protocols
As of 2025, the primary active Ethereum testnets are:
- Goerli: The most established proof-of-authority (PoA) testnet, widely supported across tools and wallets.
- Sepolia: A newer proof-of-stake (PoS) testnet designed to better reflect post-Merge Ethereum’s consensus mechanism.
Deprecated testnets like Ropsten, Rinkeby, and Kovan are no longer maintained and should not be used.

Top Goerli Testnet Faucets (2025)
Goerli remains a go-to network for many developers due to its broad compatibility with development frameworks like Hardhat and Truffle. Below are the most reliable Goerli ETH faucets currently active.
Alchemy Goerli Faucet
One of the most trusted sources for test ETH, Alchemy's faucet provides 0.02 Goerli ETH per day per wallet. To use it:
- Create a free Alchemy account.
- Navigate to the Goerli faucet page.
- Connect your wallet or enter your address.
- Claim your daily allowance.
This faucet is ideal for consistent, small-scale testing needs.
Chainlink Faucet
The Chainlink faucet supports multiple testnets, including Goerli. By verifying your Twitter account, you can receive:
- 0.1 Goerli ETH
- 10 LINK test tokens
This dual-token offering makes it especially useful for developers integrating Chainlink oracles into their projects.
Paradigm Multi-Chain Faucet
Operated by Paradigm, this powerful tool supports several testnets, including Goerli, Polygon Mumbai, and Moonbase Alpha. Requirements include:
- A Twitter account older than one month
- At least 50 followers
- Posting a public tweet about the faucet
Upon verification, users can claim ETH, wETH, DAI, and even NFTs—making it one of the richest faucet experiences available.
AllThatNode Faucet
AllThatNode offers 0.025 Goerli ETH daily. Logging in with an account increases claim limits over time. It’s simple to use and doesn’t require social media verification.
Goerli Authenticated Faucet (Discontinued)
Previously recommended by Ethereum.org, this faucet is currently inactive. Users should rely on alternatives listed above.
Bisell.site – Purchase Option
For urgent needs, Bisell.site allows users to purchase 10 Goerli ETH at a time. While not free, this option ensures immediate access for time-sensitive development tasks.
Best Sepolia Testnet Faucets (2025)
With Goerli becoming increasingly congested due to high demand and potential airdrop farming, Sepolia has emerged as a preferred alternative. Designed as a PoS-based testnet, Sepolia better reflects Ethereum’s current architecture.
Alchemy Sepolia Faucet
Similar to its Goerli counterpart, Alchemy’s Sepolia faucet grants 0.5 Sepolia ETH per day after account registration. This generous amount makes it one of the best options for sustained testing.
QuickNode Faucet
QuickNode requires a small amount of real ETH (0.001) on the mainnet to prevent bot abuse. Once verified:
- Claim 0.05 Sepolia ETH daily
- Double the amount by sharing on Twitter
This anti-spam model ensures fair distribution while still being accessible to genuine developers.
Chainlink Faucet (Sepolia Support)
The same Chainlink faucet used for Goerli also supports Sepolia. Verified Twitter users can claim:
- 0.1 Sepolia ETH
- 20 LINK test tokens
This makes it a top choice for cross-chain oracle testing.
Infura Faucet
Infura, backed by ConsenSys (MetaMask’s parent company), offers 0.05 Sepolia ETH per day. Users must log in with an Infura account, which integrates seamlessly with MetaMask and other Web3 tools.
👉 Start building on Sepolia with powerful infrastructure and real-time node access.
Bisell.site – Sepolia Purchase Option
Like with Goerli, Bisell.site allows direct purchase of 10 Sepolia ETH tokens for urgent use cases. While not ideal for casual users, it serves professional developers needing large volumes quickly.
Frequently Asked Questions (FAQ)
Q: Why do I need testnet ETH?
A: Testnet ETH allows you to interact with dApps, deploy smart contracts, and simulate transactions without spending real money. It's essential for development and learning.
Q: Are Goerli and Sepolia both active in 2025?
A: Yes. While Goerli is well-established, Sepolia is increasingly favored due to its PoS design and more stable token supply.
Q: Why do some faucets require Twitter verification?
A: Social verification helps prevent bots from draining limited testnet resources, ensuring fair access for real developers.
Q: Can I get banned from using faucets too often?
A: Most enforce daily limits rather than bans. Exceeding rate limits may result in temporary cooldowns.
Q: Is there a risk in using third-party faucets?
A: Only use reputable faucets from known providers like Alchemy, Chainlink, or Infura. Never connect your mainnet wallet with significant funds during testing.
Q: Will testnet activity lead to airdrops?
A: Some projects reward early testers with token airdrops. Consistent interaction on testnets like Sepolia may increase eligibility.
Tips for Maximizing Testnet Usage
- Use multiple faucets daily: Combine Alchemy, Chainlink, and Infura claims for higher balances.
- Verify social accounts early: Set up Twitter verification in advance to unlock higher-tier faucets.
- Separate test wallets: Use dedicated wallets (e.g., MetaMask with “Test” label) to avoid confusion with mainnet funds.
- Monitor faucet updates: Services may change requirements or pause due to congestion—follow developer communities for news.
