  Coinbase OnchainKit is a TypeScript React framework from Coinbase for building onchain
  applications on Base and other EVM networks. It bundles ready-made React components
  (wallets, identity, transactions, swap, checkout, fund, NFT), TypeScript utilities,
  and integrations with Smart Wallet, Base Account, Frames, and Mini Apps. OnchainKit
  is distributed as the @coinbase/onchainkit npm package along with companion CLIs
  (create-onchain) and a MiniApp manifest generator. It is built on top of Wagmi,
  Viem, and TailwindCSS and is the recommended client SDK for the Base ecosystem.
