## Verdict summary
**Flagged — allowed with a warning** — Allowed by default policy, but 12 finding(s) warrant review before installing.

- **Verdict:** Suspicious
- **Product-default install policy:** Warn
- **Firewall policy:** Telemetry warning (can be blocked)
- **Public report status:** Published
- **Threat category:** Telemetry
- **Selected version:** 3.5.0
- **Selected version is latest:** No
- **Analysis source:** AI Security Review (lpm-firewall-ai)

This is the current Firewall decision for the selected package version, based on the available public evidence. Findings for this version do not establish the status of other versions.

AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy.

The 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.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1
- **Recorded final verdict:** Suspicious
- **Recorded analysis confidence:** 84.0%
- **Started:** 2026-10-31T08:11:50.918Z
- **Finished:** 2026-10-31T08:13:05.003Z
- **Download time:** 506 ms
- **Static scan time:** 9823 ms
- **AI review time:** 63755 ms
- **Total time:** 74085 ms

The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs.

## Security analysis

### Published attack-surface review

- **Summary:** Undisclosed WalletConnect runtime telemetry is enabled by default.

- **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.

- **Evidence paths:** dist/chunks/mountEngine-DI19rA1h.js

- **Review source:** ai\_review

- **Reviewed:** 2026-10-31T08:13:05.003Z

### AI review details

- **Review stage:** source\_first\_review

- **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.

- **Rationale:** The 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.

- **Files touched:** dist/chunks/mountEngine-DI19rA1h.js

- **Network endpoints:** https://pulse.walletconnect.org/batch

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 84.0%

- **Recommended action:** downgrade\_to\_warn

- **Intent class:** Unknown

- **False-positive risk:** Medium

- **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.

## Affected versions and remediation
