Arbitrum Sepolia
PoW Faucet
Verified work for Arbitrum Sepolia ETH.
Arbitrum 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.
Arbitrum Sepolia is for teams that want to prove an integration on an Arbitrum rollup, not only in a local EVM. Public testnet execution makes timing, RPC behavior, receipts, and wallet interactions visible before a release reaches real users.
Sequencer-aware pending transaction UX
Arbitrum Sepolia test gas can support sequencer-aware pending transaction UX. Start with a public address configured for chain ID 421614, 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 Arbitrum 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.
