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 inspected wallet transfer is an explicit CLI feature, and the inspected credential flow validates a user-submitted Anthropic key with the model API. - **Trigger:** Wallet transfers require a user to run \`tab evm fund\` with source and destination arguments; key validation occurs when a user submits a company model key. - **Impact:** No unauthorized transfer or credential disclosure was identified in the inspected flows. - **Review source:** ai\_review - **Reviewed:** 2026-11-03T07:35:03.454Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The CLI signs and sends the requested EVM transfer. The company server sends a submitted Anthropic key to the configured Anthropic API for validation and seals it for later company use. - **Rationale:** The package's flagged wallet transfer is a user-run funding command whose source key, destination and amount come from its arguments. The inspected Anthropic key flow validates a user-submitted key with the configured Anthropic API; no automatic theft or unauthorized spending was found. - **Network endpoints:** paidwithtab.com, pay.paidwithtab.com, Anthropic API at configured anthropicUrl ### Review decision - **Verdict:** Clean - **Confidence:** 91.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The npm entrypoint is a CLI; the package exports the buyer-side payment client., The client signs and retries a payment only after receiving an HTTP 402 challenge., The EVM token transfer requires explicit source key, destination, token and amount arguments., The company server checks a submitted Anthropic key against the configured Anthropic API, then seals it for company use. - **Evidence against:** The scanner flags wallet transfers, but the inspected transfer is behind the explicit \`evm fund\` command and uses the supplied destination and amount., The source references credentials and network calls; the inspected Anthropic key flow sends a user-submitted key to the model API for validation., The package declares a \`prepublishOnly\` build-and-test script, not an install lifecycle hook. ## Affected versions and remediation This report applies to paidwithtab@3.0.0. - Avoid installing paidwithtab@3.0.0. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.
