Drop-in crypto payment checkout for the web — a <lydian-checkout> web component and window.Lydian API across 20+ chains and major stablecoins.
AI Security Review
scanned 5d ago · by lpm-firewall-aiThe flagged Authorization flow uses a wallet-link session ID and secret with the configured link API for event handling. The manifest has no install hook, and the wallet checkout engine is loaded on demand.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
The SDK entry point is imported; wallet connection functionality loads when checkout initialization requests the engine.
Impact
No malicious impact identified in the reviewed source.
Mechanism
The reviewed session Authorization value is sent to the configured link API for unseen-event retrieval and event acknowledgment. No unrelated credential collection or destination was identified.
AI rationale
The flagged Authorization flow uses a wallet-link session ID and secret with the configured link API for event handling. The manifest has no install hook, and the wallet checkout engine is loaded on demand.

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 describes a web crypto-payment checkout SDK and exports dist/lydian.js.
- The only lifecycle script is prepublishOnly, which blocks publishing outside CI; there is no install hook.
- The wallet checkout engine is loaded dynamically by getOrLoadEngine rather than on the package entry point’s initial import.
- The flagged Authorization value is built from a session ID and session secret, then used for event operations at the configured link API URL.
Evidence against
- The scanner flags credential exfiltration, but the inspected Authorization flow is tied to the SDK’s wallet-link event API.
- The engine bundle contains network and environment-variable references, but the reviewed examples are wallet/RPC behavior and test or runtime configuration checks.
