Base Sepolia
PoW Faucet
Verified browser work for Base Sepolia ETH.
Base Sepolia PoW Faucet Rules
- Use one public 0x wallet address. A faucet never needs a private key, seed phrase, password, or exchange credentials.
- Complete verification and submit browser work until the displayed minimum becomes claimable.
- The visible cap is the maximum reward for one session, while a successful claim starts a one-hour wallet cooldown.
- ETH on this page is testnet gas only. It is not an investment and cannot be used as mainnet funds.
- Parallel sessions, synthetic shares, automated collection, and attempts to evade fairness limits can be restricted.
Base Sepolia is appropriate for teams validating a product on an OP Stack network before its public release. It lets developers inspect the practical difference between a local unit test and a transaction that travels through a real rollup environment.
OP Stack transaction lifecycle screens
Base Sepolia test gas can support OP Stack transaction lifecycle screens. Start with a public address configured for chain ID 84532, pass hCaptcha, and choose a browser-worker setting that keeps the device comfortable. Workers produce candidate proof shares only while the page is open. The service checks every accepted result itself, so a number displayed in the browser cannot independently create credit or a payout.
The work panel reports rate, accepted shares, elapsed time, earned ETH, the minimum needed to claim, and the session ceiling. Claiming opens at the threshold; reaching the cap is optional. Once a transaction is broadcast, the explorer link is the final record for its recipient, amount, and confirmation. Keep a phone tab in the foreground, because battery-saving mode can pause background work. This bounded process gives ordinary builders a predictable path to ETH without turning a public faucet into unlimited funding.
For this kind of test, configure the RPC, wallet, deployment tool, and front end for Base Sepolia before executing a script. Do not confuse a balance on another chain with a spendable balance here. If the wallet display is slow, check the explorer receipt before requesting again. A local chain, fork, or project-managed allocation is more appropriate for a large automated suite; this shared faucet is designed for a developer validating a feature, reproducing a defect, following a tutorial, or learning an end-to-end transaction flow.
