Framework Agnostic
Support all your favorite frameworks.
Use web3-onboard with any of your favorite Javascript libraries.
Minimal Dependencies
All wallet dependencies are included in separate packages, so you only include the ones you want to use in your app.
Dynamic Imports
Supporting multiple wallets in your app requires a lot of dependencies. Onboard dynamically imports a wallet and it's dependencies only when the user selects it, so that minimal bandwidth is used.
Wallet Provider Standardization
All wallet modules expose a provider that is patched to be compliant with the EIP-1193, EIP-1102, EIP-3085 and EIP-3326 specifications.
Multiple Chain Support
The best connect wallet button for allowing users to switch between chains/networks with ease.
Enable Multi-Wallet and Multi-Chain functionality with one library
Web3-Onboard is the quickest and easiest way to add multi-wallet and multi-chain support to your project. With built-in modules for more than 35 unique hardware and software wallets, Web3-Onboard saves you time and headaches.
