AI Security Review
scanned 5d ago · by lpm-firewall-aiThe scanner’s credential-flow alert resolves to a wallet-link session credential sent to its configured Link API, consistent with the wallet integration. However, the bundled WalletConnect client enables runtime telemetry by default and sends app-domain and runtime metadata without package-level disclosure, warranting a warning.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
When the app initializes the WalletConnect client, such as when its WalletConnect connector is used.
Impact
Exposes application origin and runtime integration metadata to the WalletConnect telemetry service; no credential exfiltration was identified in this flow.
Mechanism
The bundled WalletConnect event client sends an INIT event containing the app domain, client ID, and user-agent data to its telemetry endpoint, with the project ID in the request URL.

Decision evidence
public snapshotAI called this Suspicious at 84.0% confidence as Unknown with medium false-positive risk.
Evidence for warning
- WalletConnect’s event client defaults telemetry to enabled, and its core passes the optional telemetryEnabled setting through.
- The telemetry initialization event includes the application domain, a client ID, and user-agent data.
- The event client POSTs telemetry to https://pulse.walletconnect.org/batch with the WalletConnect project ID; the package does not disclose this runtime telemetry.
Evidence against
- The Basic Authorization header flagged by the scanner is built from a wallet-link session ID and key, then used with the configured Coinbase Wallet Link API URL.
- The package’s main entry imports its SDK module, which exposes explicit init and initExistingSession APIs; no install-time data collection was identified.
- The prepublishOnly script blocks publishing outside CI and does not run as an install hook.
