## Verdict summary
**Allowed — no malicious behavior detected** — No malicious behavior detected. 9 low-signal pattern(s) reviewed.

- **Verdict:** Clean
- **Product-default install policy:** Allow
- **Firewall policy:** No policy match
- **Public report status:** Published
- **Threat category:** None published
- **Selected version:** 1.48.0
- **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: clean; recommendation: mark clean. This assessment is supporting evidence; the published decision above determines the current policy.

The manifest has no install lifecycle scripts, and the inspected entry points defer MetaMask client creation and wallet-provider registration to connection and approval flows. The reviewed storage behavior supports the SDK’s session management and anonymous ID handling.

## Security analysis

### Published attack-surface review

- **Summary:** No attack was identified in the inspected package source.

- **Trigger:** Client creation and wallet pairing occur when the integration’s connection methods are called.

- **Impact:** No malicious data collection, unrelated network destination, or unrequested account action was found.

- **Review source:** ai\_review

- **Reviewed:** 2026-10-29T16:37:47.468Z

### AI review details

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

- **Mechanism:** The package delegates MetaMask client creation and session handling to its integration dependencies and uses the host client’s storage adapter.

- **Rationale:** The manifest has no install lifecycle scripts, and the inspected entry points defer MetaMask client creation and wallet-provider registration to connection and approval flows. The reviewed storage behavior supports the SDK’s session management and anonymous ID handling.

- **Files touched:** package.json, dist/index.cjs, dist/getOrCreateMetaMaskClientInstanceManager-DWy9UvhZ.cjs

### Review decision

- **Verdict:** Clean

- **Confidence:** 94.0%

- **Recommended action:** mark\_clean

- **Intent class:** Benign

- **False-positive risk:** Low

- **Evidence for AI clean decision:** The manifest points to JavaScript entry points and declares no install or lifecycle scripts., The client manager creates the MetaMask client only when getMetaMaskClient is called., Client creation passes app metadata, configured networks, and a storage adapter backed by the host client’s storage service., The connection helper starts URI pairing when called; wallet-provider registration occurs in its approval callback., The stored anonymous ID is generated with crypto.randomUUID() and persisted through the host storage service.

- **Evidence against:** The package exposes wallet connection and session storage functions, which are consistent with its MetaMask integration purpose., The manifest’s scripts are build, lint, test, and version-check commands.
