  • Viem compatibility
Looking for a pre-built UI? If you want to execute bridge transactions with a ready-made interface, consider using the Metalayer Widget instead. The Widget uses this SDK under the hood and provides a production-ready UI with built-in theming, wallet integration, and automatic transaction handling.

​
Installation

pnpm add viem @metalayer/sdk
If you plan to use the SDK’s React hooks, you’ll need to install React Query as a peer dependency.

​
Installing React Query
