**Improved WalletConnect Support**
----------------------------------

The [Web SDK](https://docs.formo.so/sdks/web) (1.38.2) can now track wallets your app constructs in code, not just the ones a browser injects from EIP-1193.

Wallet discovery covers wallets that announce themselves and wallets that sit at `window.ethereum`, which is every injected browser wallet and nothing else. A provider your app builds in code, such as WalletConnect, announces nothing.

Hand the provider over with `registerProvider` and it takes the same path a discovered wallet does: [connect](https://docs.formo.so/data/events/connect) and [disconnect](https://docs.formo.so/data/events/disconnect) lifecycle events, and [signature](https://docs.formo.so/data/events/signature) and [transaction](https://docs.formo.so/data/events/transaction) autocapture.

    formo.registerProvider(provider);
    

> Using [Wagmi mode](https://docs.formo.so/sdks/web#wagmi-integration)? This is automatically handled for you and you don’t need to make any changes.

See the [WalletConnect integration guide](https://docs.formo.so/sdks/web#walletconnect-integration) to get started.

**EIP-1193 Fallback for Wagmi Mode**
------------------------------------

[Wagmi](https://docs.formo.so/sdks/web#wagmi-integration) mode captures [signature](https://docs.formo.so/data/events/signature) and [transaction](https://docs.formo.so/data/events/transaction) events from Wagmi hooks. However, if your app also sends imperatively through viem, with `sendTransaction`, `.signMessage`, or `.writeContract`, those calls create no Wagmi mutation and were never captured.

Opt in with `eip1193Fallback` and the SDK instruments the active connector’s provider with the same request wrapper the EIP-1193 mode uses:

    wagmi: ‍​{ ‍​eip1193Fallback: ‍​true ‍​}
    

Upgrade to the [latest SDK](https://github.com/getformo/sdk/releases) to get started.
