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 transfer code implements payment for API calls: it is activated by a payment-required response and sends the signed payment with the retry. The manifest has no install lifecycle hook, and the inspected entrypoints show no separate wallet-draining behavior. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 95.0% - **Started:** 2026-10-18T12:02:51.398Z - **Finished:** 2026-10-18T12:03:38.023Z - **Download time:** 762 ms - **Static scan time:** 2139 ms - **AI review time:** 43720 ms - **Total time:** 46625 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 surface was identified. The wallet feature signs payments for API requests as part of the package's billing behavior. - **Trigger:** A caller makes an API request and the configured service responds with a payment requirement. - **Impact:** This is a user-invoked payment flow; inspected source does not establish an unrelated or unrequested transfer. - **Review source:** ai\_review - **Reviewed:** 2026-10-18T12:03:38.023Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The client parses the payment requirement, signs the stated recipient and amount, then sends the signature with a retry to the same request URL. - **Rationale:** The flagged wallet transfer code implements payment for API calls: it is activated by a payment-required response and sends the signed payment with the retry. The manifest has no install lifecycle hook, and the inspected entrypoints show no separate wallet-draining behavior. ### Review decision - **Verdict:** Clean - **Confidence:** 95.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The manifest points to the ESM and CommonJS bundles and declares no install lifecycle hook., The ESM client defaults to BlockRun's API., Wallet payment signing follows a 402 response and uses the recipient and amount parsed from its payment requirements., The signed resource URL is restricted to the configured API's hostname and protocol., The paid retry posts to the same request URL with the payment signature., The CommonJS bundle signs a transfer authorization for the supplied recipient and amount. ## Affected versions and remediation This report applies to @blockrun/llm@3.21.0. - Review the evidence and your use of @blockrun/llm@3.21.0 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.
