What is Sepolia?

Sepolia Testnet is a testing environment within the Ethereum ecosystem designed for developers and users to experiment with and test their decentralized applications (dApps) and smart contracts before deploying them on the Ethereum mainnet. It mimics the Ethereum mainnet's functionality but uses test tokens instead of real Ether (ETH) to allow for risk-free testing and development.
