Installation

Install Wagmi Core via your package manager, a <script> tag, or build from source.

Package Manager

Install the required packages.

pnpm

pnpm add @wagmi/core viem@2.x

npm

npm install @wagmi/core viem@2.x

yarn

yarn add @wagmi/core viem@2.x

bun

bun add @wagmi/core viem@2.x

• Viem is a TypeScript interface for Ethereum that performs blockchain operations.
• TypeScript is optional, but highly recommended. Learn more about TypeScript support.

CDN

If you're not using a package manager, you can also use Wagmi Core via an ESM-compatible CDN such as esm.sh. Simply add a <script type="module"> tag to the bottom of your HTML file with the following content.

<script type="module">
  import { createClient } from 'https://esm.sh/viem'
  import { createConfig } from 'https://esm.sh/@wagmi/core@2.x'
  import { injected } from 'https://esm.sh/@wagmi/connectors'
</script>

Requirements

Wagmi is optimized for modern browsers. It is compatible with the latest versions of the following browsers.

TIP

Depending on your environment, you might need to add polyfills. See Viem Platform Compatibility for more info.

Using Unreleased Commits

If you can't wait for a new release to test the latest features, you can either install from the canary tag (tracks the main branch).

pnpm

pnpm add @wagmi/core@canary

npm

npm install @wagmi/core@canary

yarn

yarn add @wagmi/core@canary

bun

bun add @wagmi/core@canary

Or clone the Wagmi repo to your local machine, build, and link it yourself.

gh repo clone wevm/wagmi
cd wagmi
pnpm install
pnpm build
cd packages/core
pnpm link --global

Then go to the project where you are using Wagmi and run pnpm link --global @wagmi/core (or the package manager that you used to link Wagmi globally). Make sure you installed any required peer dependencies and their versions are correct.

Security

Ethereum-related projects are often targeted in attacks to steal users' assets. Make sure you follow security best-practices for your project. Some quick things to get started.

• Pin package versions, upgrade mindfully, and inspect lockfile changes to minimize the risk of supply-chain attacks.
• Install the Socket Security GitHub App to help detect and block supply-chain attacks.
• Add a Content Security Policy to defend against external scripts running in your app.
