The best way to connect a wallet 🌈 🧰
RainbowKit is a React component library for adding wallet connection UI to Ethereum dapps. It sits on top of wagmi and viem, handling the modal, wallet list, account display, and chain switching so you don't have to build that yourself. Aimed at React/Next.js developers building web3 frontends who want polished wallet UX without rolling their own.
- Built on wagmi/viem rather than reinventing the wheel — you get proper type safety and all of wagmi's connector ecosystem for free
- Multiple working examples covering Next.js App Router, Remix, Vite, SIWE with iron-session/next-auth, and custom button patterns — actually useful for getting unstuck
- Theming system is real: you can override colors, fonts, border radius, and supply custom CSS variables, or build a completely custom connect button via the useConnectModal hook
- Active maintenance with changesets-based versioning, Crowdin i18n integration, and CodeQL security scanning in CI
- Hard React dependency means it's useless in Vue, Svelte, or vanilla JS projects — there's no framework-agnostic core
- Opinionated modal UI is a blessing until it isn't: deep customization (e.g. reordering the wallet list dynamically, injecting custom steps) requires forking the package or using the escape-hatch custom button approach, which loses most of the built-in UX
- Tight wagmi version coupling means major wagmi upgrades frequently break RainbowKit and require coordinated bumps — if your project pins wagmi for other reasons you can get stuck
- Bundle size is non-trivial; it pulls in wallet-specific icons and detection logic for 30+ wallets regardless of which ones you configure, which matters for performance-sensitive dapps
