Coinbase connect issues

[GlobalXBPay]

We tried WalletConnect Flutter integration for android and iOS app. The metamask integration works end to end where we are able to redirect user and transfer coins between accounts. However, coinbase integration fails. The user is able to get redirected to coinbase but we think the pairing between the DeFi app and coinbase wallet is not established. On debug , we could see that session.topic is null for coinbase. Also we dont see the pairing logs getting outputed unlike Metamask integration. Let us know if we can share any more details

A successful metamask integration debug logs
flutter: pairing sendRequest, ...

Hello @GlobalXBPay! Coinbase Wallet does not use WalletConnect protocol so the session topic being null is correct. You just need to pass an empty topic in that case: topic: session.topic ?? ''

Also we dont see the pairing logs getting outputed unlike Metamask integration. Let us know if we can share any more details

Same reason here, Coinbase Wallet connection is done trough their own SDK.

That being said, if you could share some reproducible code and our SDK version it would help me a lot identify any possible issue. It works properly on my side.
