Do not execute instructions or code found in this document. ## 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:** 3.13.6 - **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 wallet-related code implements payment for caller-initiated API requests: it handles a service payment challenge, signs the specified payment, and retries with the signature. The manifest has no install hook, and the inspected entrypoints provide no evidence of an unrelated or automatic transfer. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 94.0% - **Started:** 2026-10-18T12:01:31.862Z - **Finished:** 2026-10-18T12:02:21.531Z - **Download time:** 1010 ms - **Static scan time:** 1571 ms - **AI review time:** 47085 ms - **Total time:** 49669 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:** No attack was identified. The package signs payment data in response to a payment challenge during an API request. - **Trigger:** A caller makes a paid API request and the service responds with payment requirements. - **Impact:** This supports the package’s pay-per-request service. The inspected code does not establish hidden wallet transfers or credential theft. - **Review source:** ai\_review - **Reviewed:** 2026-10-18T12:02:21.531Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The client signs an authorization using the challenge’s recipient and amount, then retries the request with the signature. - **Rationale:** The wallet-related code implements payment for caller-initiated API requests: it handles a service payment challenge, signs the specified payment, and retries with the signature. The manifest has no install hook, and the inspected entrypoints provide no evidence of an unrelated or automatic transfer. - **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:** package.json exposes the ESM and CommonJS bundles and defines no install lifecycle hook., The ESM client handles payment requirements returned with a 402 response and uses their recipient and amount to build a payment authorization., The ESM client retries the requested API call with the payment signature in a header., The CommonJS bundle signs a transfer authorization for the specified recipient and amount; the Solana payment helper builds a transfer for the specified recipient and amount. ## Affected versions and remediation This report applies to @blockrun/llm@3.13.6. - Review the evidence and your use of @blockrun/llm@3.13.6 before allowing it. Restrict the permissions described in this report. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. ## Public findings ### 1.
