Free Optimism Sepolia ETH for OP Stack testing, dApps, wallets, and Layer 2 learning
Simple · Fast · Reliable
Optimism Sepolia is a testnet for users and builders who want hands-on experience with Optimism-style Layer 2 transactions.
Faucet Show distributes Optimism Sepolia ETH so wallets can pay testnet gas for dApp interactions, smart contract calls, ecosystem tasks, and development experiments.
The faucet is built for practical learning: it helps a new wallet move from empty to usable without asking the user to risk real assets.
Optimism Sepolia is a strong environment for learning how optimistic rollups, EVM compatibility, and Layer 2 user experience come together.
Developers can test OP Stack-related applications, contract deployment, transaction handling, and cross-network assumptions before launching in production.
New users can practice the small but important details: adding the right network, watching gas estimates, approving transactions, and finding the transaction hash afterward.
Community testers can use the network to join testnet campaigns more responsibly by understanding what each wallet prompt is asking them to do.
Enter your public EVM wallet address in the request box.
Confirm that Optimism Sepolia is selected in your wallet before checking for the incoming testnet ETH.
Complete captcha verification, then submit the request.
If the transfer is successful but the wallet looks unchanged, refresh the wallet or review the transaction on an Optimism Sepolia explorer.
Optimism Sepolia helps users understand Layer 2 networks through direct action rather than theory alone.
For developers, it can reveal practical issues with network detection, gas handling, contract events, and explorer links before the app reaches real users.
For beginners, it builds the habit of checking the chain, reading the transaction, and treating every approval with attention.
Wrong chain: Switch from Optimism mainnet or Ethereum Sepolia to Optimism Sepolia.
No gas after claim: Wait for the faucet transaction to confirm and refresh your wallet.
Captcha problem: Reload the page and complete a fresh captcha challenge.
Cooldown active: Wait until the 60 minute cooldown has passed.
Contract call fails: Check that the dApp supports Optimism Sepolia and that your wallet has testnet ETH.
Understanding these issues helps users solve simple problems faster, avoid repeated failed requests, and build better habits when testing any blockchain network.
No. It is a testnet for development and learning.
Optimism Sepolia uses testnet ETH for gas.
Yes. It is useful for testing OP Stack-compatible application flows.
Yes, for testnet practice and campaign interactions when supported by the project.
Most failures are caused by cooldown, captcha, or an incorrect address.
Never. A faucet only needs your public wallet address.
