Fix: “Connection was established via this URL”

This file used to be written in Russian; it is now fully in English.

🔴 Problem

When scanning a WalletConnect QR code, the wallet rejects the connection and shows:

“Connection was established via this URL”

⚡ Solution (root cause)

Real cause: the Rust implementation used optional_namespaces instead of required_namespaces for Qubic.

See the detailed write-up: WALLETCONNECT_FIX_REQUIRED_NAMESPACES.md

🔍 Analysis

The JavaScript SDK uses requiredNamespaces for core chain methods. The wallet expects the chain methods to be required; otherwise it may treat the proposal as invalid/duplicate.

✅ Code changes

  1. Namespaces fix: Qubic is now set in required_namespaces.
  2. Reconnect safety: cleanup_old_state() clears stale listeners/session state before generating a new URI.

🎯 Result

  • ✅ each run generates a clean, unique connection
  • ✅ stale sessions/state are cleared before reconnect
  • ✅ wallet accepts the new QR codes
