What Is a Faucet?

By DappAtlas editors ·

On this page

A faucet is a website or service that sends small amounts of free testnet tokens to your address so you can pay gas on a test network.

Key takeaways

  • Faucets give testnet tokens, which have no value.
  • Most limit amounts and how often you can ask.
  • Many ask you to log in or hold a small mainnet balance to stop bots.
  • A faucet never needs your seed phrase or private key.

How a faucet works

You paste your wallet address, pass a check such as a captcha or login, and the faucet sends tokens from its own balance on the testnet.[1]

Why faucets have limits

Testnet tokens are free, so faucets limit amounts, add cooldowns or require a small mainnet balance to keep bots from draining them.

Risks and scams

A real faucet only needs your public address. Any site that asks for your seed phrase or asks you to sign a transaction to “claim” is a scam.[2]

The Bottom Line

Use a faucet to get free tokens for testing, and share nothing but your address.

Faucet FAQ

Why does a faucet ask for a mainnet balance?

To prove you are a real user, not a bot. The mainnet funds are not taken; the faucet only checks the balance.

Is a faucet safe to use?

Yes, if it only asks for your public address. Never enter a seed phrase or private key.
