RainbowKit: a React wallet-connect layer for dapps

What RainbowKit actually removes from a dapp build

Connecting a wallet is a small feature with a long tail. You need a modal, a list of wallets, per-wallet icons, a connected-account display, a chain switcher, and error states for the case where the user rejects the request or has the wrong network selected. RainbowKit packages that surface as React components so you configure it once and render a button.

The README states the library "makes it easy to add wallet connection to your dapp" and lists out-of-the-box wallet management as its first feature. That framing is accurate about scope. RainbowKit is the presentation and orchestration layer; it does not replace the connector logic underneath. The repository describes it as built on top of wagmi and viem, which is where the account, chain and transport state actually lives.

The audience is narrow and clearly stated: React developers. The README says React directly, the examples folder is React throughout, and the packages directory splits into the core library, a Rainbow Button package, a SIWE NextAuth integration and a scaffolder. If your frontend is not React, nothing in the repository layout suggests a path for you.

How the wagmi and viem dependency shapes your app

The dependency direction matters more than the component API. RainbowKit sits above wagmi, and wagmi sits above viem. That means your app configures connectors and chains through wagmi, and RainbowKit renders the interface for them. You are not choosing between RainbowKit and wagmi; adopting RainbowKit means adopting wagmi as well.

This is why the phrase "rainbowkit vs wagmi" is a category error. They occupy different layers. wagmi gives you hooks for reading accounts, sending transactions and switching chains. RainbowKit gives you the modal and the button that call into that state. Removing RainbowKit would leave your wagmi configuration intact and force you to build the UI yourself.

The practical consequence is that wallet support is not a RainbowKit setting you toggle in isolation. The README points to a scripts/walletRegistry.js file invoked by the fetch:wallets script, which suggests the project maintains a wallet registry for its default list. Your own connector set still comes from wagmi configuration. When a wallet fails to appear in the modal, the first place to look is the connector list you passed to wagmi, not the RainbowKit component props.

Installing RainbowKit with the scaffolder and rendering a connect button

The README gives a one-command scaffold for a new RainbowKit + wagmi + Next.js app. Pick the command matching your package manager. With npm it is:

npm init @rainbow-me/rainbowkit@latest

pnpm and yarn have equivalents in the README (`pnpm create @rainbow-me/rainbowkit@latest` and `yarn create @rainbow-me/rainbowkit`). The scaffolder generates a project already wired to wagmi and Next.js, so the provider setup is done for you. What you should see afterwards is a working app with a connect button in the header.

If you would rather read the integration before running a generator, the repository ships runnable examples. To run one locally you install dependencies at the repo root, then move into the example directory and start the dev script:

pnpm install
cd examples/with-next
pnpm run dev

The README names `with-next` as the example for this sequence. Other example directories in the repository include `with-next-app`, `with-vite`, `with-remix`, `with-react-router`, `with-create-react-app`, `with-next-mint-nft`, `with-next-custom-button`, `with-next-siwe-next-auth` and `with-next-siwe-iron-session`.

For a hosted look at the same code without cloning, the README links CodeSandbox sandboxes for Create React App, Next.js, Next.js App Router, Remix, Vite and React Router. That is the fastest way to see the provider tree and the button placement before you touch your own codebase.

Where RainbowKit stops being the right tool

The React-only constraint is the hard boundary. The related search phrase "Rainbowkit vue" reflects a real demand, and the repository offers nothing for it: no Vue package, no Vue example, no framework-agnostic core documented in the README. The same applies to React Native. If your target is a mobile app rather than a web frontend, this library is not the layer you want.

Chain coverage is the second boundary. The topics list Ethereum, and the README's examples are EVM dapp scenarios. A search for "rainbowkit solana" has no answer in this material. Do not assume a non-EVM chain is supported because a wallet in the modal happens to support it; the connector layer is what determines which chains you can actually transact on.

There is also a versioning cost. The repository is a pnpm workspace with Changesets in the tree and a `changeset` script, which means releases are cut as versioned packages rather than as a rolling main branch. Recent releases include @rainbow-me/[email protected], @rainbow-me/[email protected] and @rainbow-me/[email protected]. Note the version spread: the core library is on 2.x while the SIWE integration is still on 0.x. If you depend on the SIWE package, you are tracking a pre-1.0 surface and should expect its API to move independently of the core library.

Finally, RainbowKit is a UI layer, so it cannot fix a connector problem. If a wallet's injected provider is broken in a given browser, a nicer modal will not repair it.

RainbowKit against WalletConnect and ConnectKit

WalletConnect is the comparison people search for most, and the two are not substitutes. WalletConnect is a protocol and SDK for relaying messages between a dapp and a wallet, including wallets that are not injected into the page. RainbowKit is a React component layer that presents connection options to the user. A RainbowKit app can use WalletConnect under the hood through wagmi; that is a stack, not a choice.

ConnectKit is the closer alternative, because it also renders a wallet-connect modal for React dapps. The difference in approach is what sits underneath. RainbowKit is documented here as built on wagmi and viem, so its configuration model is wagmi's. If your app already runs on wagmi, RainbowKit is the shorter path because the provider tree and connector config are shared. If your app is built on a different connector stack, adopting RainbowKit means adopting wagmi and viem alongside it, which is a larger change than swapping one modal component for another.

The repository also ships @rainbow-me/rainbow-button, a standalone button package, for cases where you want the button without the full modal surface. That sits between the two extremes: less than the full library, more than hand-rolling a button against wagmi hooks.

Maintenance cadence, licence and upgrade cost

The repository is not archived. The most recent push recorded here is 2026-05-12, and the newest core release listed is @rainbow-me/[email protected] from 2026-05-06. Treat that as the current state of the project rather than as a promise about the next release.

The tooling in package.json tells you what an upgrade costs you. The workspace uses pnpm with a lockfile and a workspace file, Biome for lint and format, Vitest for unit tests, and Changesets for release management. The `clean` script removes the dist folders for rainbowkit, rainbowkit-siwe-next-auth, rainbow-button and create-rainbowkit before reinstalling, which is the maintainers' own answer to a stale build. The `test:cli` script runs a build test for the scaffolder, so the generator is exercised in CI rather than trusted.

Licensing is straightforward. The README states the project is licensed under the MIT License, Copyright © 2022-present Rainbow. MIT permits commercial use and modification with the licence and copyright notice retained. That is the extent of what the material states; it is not legal advice, and if you redistribute the library inside a product you should read the LICENSE file in the repository rather than this summary.

One upgrade hazard is worth naming. Because the core library, the SIWE integration and the button package version separately, a coordinated bump is not automatic. Check each package you depend on against its own release entry rather than assuming the core version implies the others.

Editorial conclusion

Adopt RainbowKit when you are building a React dapp and want wallet connection to be a component you drop into the tree rather than code you write. Do not adopt it for a Vue, React Native or non-React frontend: the repository lists no such target, and the examples folder covers Create React App, Next.js, Remix, Vite and React Router only. Before committing, verify the current @rainbow-me/rainbowkit version on npm, confirm your wallet list against the wagmi connectors your app already configures, and check whether the SIWE packages match your session strategy. The last push to the repository was on 2026-05-12.
