✅ No issues found

The dependency update from utils-rs rev 28c1255 to 9486ec2 appears clean:

• Direct dependency: wc (utils-rs) updated to newer revision
• Transitive dependency: metrics-exporter-prometheus 0.17.2 → 0.18.1
• Usage: 12 crates depend on wc workspace dependency with various features
• No external domains: All URLs point to approved WalletConnect GitHub repository
• No static resources: No cache-control concerns in this change

Without access to compile/test (review-only mode), cannot verify runtime compatibility, but lockfile shows clean resolution of all transitive dependencies.
