Learn how to get testnet ETH on test networks like Sepolia and OP Sepolia for development and testing purposes.
Faucets are developers tools that allow you to get free ETH (and other tokens) on test networks like Sepolia and OP Sepolia so that you can send transactions and create smart contracts. Here you’ll find a list of active faucets that you can try out. Different faucets use different authentication methods, so you may have to try a few before you find one that works for you. Faucets can occasionally also run out of ETH, so if you’re having trouble getting ETH from a faucet, try another one.This page includes providers that meet specific inclusion criteria, as outlined below. Please visit the community faucets page for an additional listing of third-party faucets.
Tokens on test networks like Sepolia or OP Sepolia have no value and are only meant for testing.
Optimists only take what they need so that others can use faucets too!
