## Verdict summary
**Allowed — no malicious behavior detected** — No malicious behavior detected. 12 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:** 3.16.0
- **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 flagged wallet-signing behavior is part of the package's stated payment functionality and is driven by payment requirements returned during a paid request. The manifest has no install hook, and the inspected ESM and CommonJS paths show no separate attack behavior.

## Latest scan

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:** No attack was identified. The wallet transfer signing supports the package's stated per-call USDC payment feature.

- **Trigger:** A caller makes a paid SDK request and receives payment requirements in a 402 response.

- **Impact:** The wallet authorizes the requested payment; the inspected source does not establish an unrelated or hidden transfer.

- **Review source:** ai\_review

- **Reviewed:** 2026-10-18T12:02:23.281Z

### AI review details

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

- **Mechanism:** The client signs a short-lived USDC authorization using the caller's wallet and the recipient and amount in those payment requirements.

- **Rationale:** The flagged wallet-signing behavior is part of the package's stated payment functionality and is driven by payment requirements returned during a paid request. The manifest has no install hook, and the inspected ESM and CommonJS paths show no separate attack behavior.

- **Files touched:** package.json, dist/index.js, dist/index.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 describes per-call USDC payments as SDK functionality and has no install lifecycle script., The ESM payment builder signs a USDC authorization from the caller's wallet to a supplied recipient for a supplied amount., The ESM runtime builds that payment from requirements parsed from a 402 response during a paid request., The CommonJS entrypoint follows the same 402 payment flow.
