What is PoW Faucet (pk910)?
PoW Faucet is an open-source testnet faucet by developer pk910 that pays test ETH for mining work done in your browser. Public instances serve Sepolia, Hoodi and Ephemery. On Sepolia a session pays 0.05 to 2.5 SepETH and lasts up to 24 hours, with no account or mainnet balance needed.
How PoW Faucet (pk910) works
You enter an ETH address and your browser tab starts hashing.
The README is clear that this mining creates no coins: it is a protection method that stops anyone from draining the faucet wallet, and whoever runs an instance has to fund that wallet themselves. On the Sepolia instance the algorithm is cryptonight, the config caps accepted hashrate at 1,000 H/s, and the wiki says GPU mining is not allowed. Once your balance reaches 0.05 SepETH you can stop and claim, up to a 2.5 SepETH cap.
The code is modular. Operators can combine captcha (hCaptcha, reCAPTCHA or Cloudflare Turnstile), IP limits, mainnet balance checks, GitHub login, Zupass tickets and Gitcoin Passport scoring. The public Sepolia instance requires a captcha to start a session and uses Passport stamps as a boost: in its config a higher score raises your reward factor, up to 6x. A faucet-balance module lowers drop amounts when the faucet wallet runs low.
How to start with PoW Faucet (pk910)
- Open sepolia-faucet.pk910.de, hoodi-faucet.pk910.de or ephemery-faucet.pk910.de, solve the captcha, enter your address and start mining.
- Keep the tab open.
- The Sepolia config sets a 12-hour limit on mining and a 24-hour session timeout, so claim before it runs out.
- The server restores session progress from its database after a restart.
- You need no account and no mainnet ETH on the public Sepolia instance.
PoW Faucet (pk910) fees and limits
The faucet is free. What you spend is CPU time and electricity while the tab mines. The Sepolia page asks users with leftover Sepolia ETH to send it back to the faucet wallet at 0x6Cc9397c3B38739daCbfaA68EaD5F5D77Ba5F455 so others can claim it. Running your own instance means funding its wallet yourself, per the README.
Risks to know before using PoW Faucet (pk910)
- This is one developer's project under AGPL v3, with no service guarantee, and supported networks change: the wiki home still lists Holesky, while the README now lists Sepolia, Hoodi and Ephemery.
- The operator also warns against selling testnet ETH.
- It says that over its Goerli lifetime more than 10 million GoETH ended up locked in speculation and trading pools, while only about 1 million GoETH were given out for development.
