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 credential-related Coinbase flow uses a session secret for requests to its configured link API, so the scanner’s exfiltration alert is not confirmed. However, checkout initialization triggers default WalletConnect telemetry that includes the app domain and browser metadata, which is not disclosed in the package README; classify as suspicious telemetry.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
A caller initializes checkout and the WalletConnect client is initialized.
Impact
The checkout site’s domain and pseudonymous client and browser metadata are disclosed without a documented package-level opt-out.
Mechanism
The event client sends an initialization event containing the app domain, generated client ID, and relayer user agent to WalletConnect’s pulse endpoint.

Decision evidence
public snapshotAI called this Suspicious at 86.0% confidence as Unknown with medium false-positive risk.
Evidence for warning
- The WalletConnect event client enables telemetry by default and sends an initialization event outside test mode.
- That event includes the app domain, a client ID, and a relayer user agent; it is posted to WalletConnect’s pulse endpoint.
- The telemetry path is reached when checkout initialization loads the engine and initializes a WalletConnect client.
Evidence against
- The manifest has no install, preinstall, or postinstall hook; its prepublishOnly script is a publish guard.
- The flagged Coinbase link flow builds Basic auth from the supplied session ID and secret and sends it to the configured link API.
- The telemetry is limited to an initialization event and browser or app metadata; no credential theft was identified.
