The article specifically mentions the Sepolia testnet, which debuted in 2021 and offers faster syncing and requires less disk space compared to the Goerli testnet. It recommends using reputable Sepolia faucets provided by companies like Alchemy and QuickNode to obtain free Sepolia ETH for testing purposes. It also warns against scammers who may try to charge for using a Sepolia faucet. The article concludes by encouraging readers to have fun and expand their knowledge about Ethereum on the Sepolia testnet.
