What Is Faucet?
Also known as: Crypto Faucet, Testnet Faucet, Bitcoin Faucet
In short
A faucet is a web service that distributes small amounts of coins or tokens to users; today it is most commonly used by developers to obtain free test coins to pay transaction fees on test networks.
Test networks (testnets) operate under the same rules as the main network (mainnet), but the coins on them have no market value. A developer who wants to deploy a smart contract or try out an application needs these test coins to cover transaction fees. A faucet sends a set amount to a user's wallet address once they enter it; to prevent abuse, it usually applies a daily limit, bot verification, social account verification, or a requirement of a minimum mainnet balance on the address.
The concept's origins go back to Bitcoin's early years: in 2010, Bitcoin developer Gavin Andresen set up a faucet site that gave visitors free bitcoin to encourage new users. In the following years, faucet sites that distributed very small amounts of real coins in exchange for ad revenue became widespread.
Some of these sites carry risks such as excessive advertising, malware, or personal data collection. Getting coins from a faucet never requires entering a private key or recovery phrase; sites that ask for them are scams.
