## 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:** 3.4.0
- **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 authorization is derived from a wallet-link session and sent to its configured Coinbase Wallet service; the reviewed entry and lifecycle script show no automatic credential collection or install-time contact. The package’s observed network behavior fits a web checkout and wallet-connect SDK.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1
- **Recorded final verdict:** Clean

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 identified; observed network and credential use support the wallet checkout and connection features.

- **Trigger:** Wallet connection and telemetry occur through SDK runtime behavior; the checkout engine loads during initialization.

- **Impact:** No unauthorized collection, credential exfiltration, or other harmful impact was identified.

- **Review source:** ai\_review

- **Reviewed:** 2026-10-31T08:13:14.869Z

### AI review details

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

- **Mechanism:** Wallet-link requests use a session-derived Basic authorization value at the configured Coinbase Wallet link server. WalletConnect event submission is guarded by its telemetry-enabled setting.

- **Rationale:** The flagged authorization is derived from a wallet-link session and sent to its configured Coinbase Wallet service; the reviewed entry and lifecycle script show no automatic credential collection or install-time contact. The package’s observed network behavior fits a web checkout and wallet-connect SDK.

- **Network endpoints:** https://rpc.walletconnect.org/v1, https://verify.walletconnect.com, https://verify.walletconnect.org

### Review decision

- **Verdict:** Clean

- **Confidence:** 94.0%

- **Recommended action:** mark\_clean

- **Intent class:** Benign

- **False-positive risk:** Low

- **Evidence for AI clean decision:** The package entry loads its SDK bundle, and the \`prepublishOnly\` script only guards publishing through CI., The checkout engine is loaded when initialization requests it, rather than when the entry module is imported., The flagged Basic authorization is formed from a wallet-link session ID and secret and sent to the configured Coinbase Wallet link server., The WalletConnect event sender is guarded by a telemetry-enabled flag; telemetry is not sent when that flag is false.

- **Evidence against:** The scanner flagged possible credential exfiltration, but the reviewed flow uses a wallet-link session credential for the documented wallet service., The package declares no install, preinstall, or postinstall hook.

## Affected versions and remediation
