What Is the Spectrum Ethereum Sepolia Faucet?
The Ethereum Sepolia faucet is a free Spectrum Nodes service that drips 0.1 ETH every 24 hours to your testnet wallet.

Ethereum Sepolia is a testnet for Ethereum mainnet, the proof of stake layer 1 that layer 2s such as Arbitrum, Base and Optimism settle on. Use the ETH to deploy contracts, test dApps and infrastructure, interact with the Ethereum ecosystem and try Ethereum's performance.
