RainbowKit Version

Current Behavior

The Rainbow Wallet app on iPhone is unable to scan the Rainbow QR code in the RainbowKit modal. If I select WalletConnect in the modal instead, the scan completes successfully.

I can reproduce this on rainbowkit.com using the "Connect Wallet" button using the latest version of Rainbow Wallet on my iPhone 15 Pro. My Mac (displaying the QR code) is using Safari 17.6.

I can also reproduce this issue in Firefox 130.0 on my Mac (displaying the QR code) using the demo on rainbowkit.com, so this isn't specific to Safari.

I have the same problem

Investigating! It seems like WalletConnect recently introduced a change that increased the length of the URIs we embed in QR Codes.
