AI Security Review
scanned 5d ago · by lpm-firewall-aiThe package exports a browser checkout SDK, and the inspected network and credential flows serve payment and wallet connection features. The scanner's credential finding traces to a session credential sent to Coinbase WalletLink, not to an unrelated collector; no malicious behavior was identified.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
The checkout engine loads when the consumer calls initialize(); wallet-link requests occur as part of wallet connection.
Impact
No automatic credential exfiltration, unrelated account action, or other malicious behavior was found.
Mechanism
The SDK uses payment APIs and wallet connection services. The flagged session credential is sent as authentication to the configured Coinbase WalletLink service.
AI rationale
The package exports a browser checkout SDK, and the inspected network and credential flows serve payment and wallet connection features. The scanner's credential finding traces to a session credential sent to Coinbase WalletLink, not to an unrelated collector; no malicious behavior was identified.

Decision evidence
public snapshotAI called this Clean at 91.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- The manifest exports the browser SDK from dist/lydian.js and declares no install-time lifecycle hook; prepublishOnly only restricts publishing to CI.
- The checkout engine is loaded when initialize() is called.
- The wallet-link client sends its session ID and key as Basic authentication to its configured link API for wallet event requests.
- The link API default is Coinbase WalletLink at https://www.walletlink.org, consistent with the wallet connection functionality.
