The Sepolia testnet is a proof-of-stake (PoS) testnet where application developers can test their smart contracts without having to spend real ETH tokens. The Ethereum foundation is deprecating the Goerli testnet, and recommends developers should use the Sepolia network instead of Goerli.

Base is a Layer 2 blockchain who recently launched their Base Sepolia testnet. Developers building on Base are encouraged to migrate their testnet applications from Base Goerli to Base Sepolia. To start the migration, follow these steps to get free Base Sepolia testnet tokens.
