## 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:** 3.7.2
- **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 bundle enables WalletConnect telemetry by default and sends app-domain and runtime metadata to WalletConnect Pulse, without a visible opt-out in this package’s initialization path. This supports a warning for undisclosed runtime telemetry, not a malicious verdict.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1
- **Recorded final verdict:** Suspicious
- **Recorded analysis confidence:** 83.0%
- **Started:** 2026-10-31T08:12:45.219Z

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:** Default-enabled WalletConnect telemetry creates a runtime privacy risk; no attack was identified.

- **Trigger:** The WalletConnect client initializes during the checkout wallet-connection flow.

- **Impact:** WalletConnect can receive information about the app using the SDK and its runtime use; the inspected flow does not show credential theft or unrelated actions.

- **Evidence paths:** dist/chunks/mountEngine-Dd6Llndl.js

- **Review source:** ai\_review

- **Reviewed:** 2026-10-31T08:13:44.898Z

### AI review details

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

- **Mechanism:** The bundled event client sends telemetry batches containing the app domain, a client ID, user-agent data, and event metadata to WalletConnect Pulse.

- **Rationale:** The bundle enables WalletConnect telemetry by default and sends app-domain and runtime metadata to WalletConnect Pulse, without a visible opt-out in this package’s initialization path. This supports a warning for undisclosed runtime telemetry, not a malicious verdict.

- **Files touched:** dist/chunks/mountEngine-Dd6Llndl.js

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

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 83.0%

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

- **Intent class:** Unknown

- **False-positive risk:** Medium

- **Evidence for warning:** The bundled WalletConnect event client defaults telemetry to enabled., Its initialization event includes the app domain, a client ID, and user-agent data., Telemetry batches are posted to https://pulse.walletconnect.org/batch., The checkout lazily loads the engine, which initializes the WalletConnect client when requested., The checkout API sends its publishable key to the configured base URI.

- **Evidence against:** The observed telemetry contains runtime and app-domain metadata, not credentials or file contents., The package is a crypto checkout SDK, and the WalletConnect traffic is part of its wallet-connection flow., The flagged Basic authorization is formed from session values and sent to the configured link API.

## Affected versions and remediation
