Base is an Ethereum L2 built on Optimism's OP Stack and incubated by Coinbase. EVM-compatible, written in Solidity, with native integration into Coinbase products and smart wallet (passkey + paymaster) for zero-gas onboarding.
One package (OnchainKit) gives you wallet + transaction + identity as one-line APIs. Smart Wallet means users connect with a passkey and pay no gas on their first txs. For vibe coders: write a prompt, ship a component, deploy, onboard a user in 30 seconds.
