@lydianpay/sdk-web@3.11.1
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 scanner’s credential signal resolves to WalletLink session authentication within a crypto payment and wallet integration SDK. The manifest has no install hook, and the public checkout initialization requires application-supplied payment details and a publishable key.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
The consuming app explicitly initializes the checkout; wallet relay behavior is used as part of wallet integration.
Impact
No unauthorized collection or transmission of machine credentials, project data, or unrelated account actions was identified.
Mechanism
The WalletLink code builds Basic auth from its session ID and secret and sends it to the WalletLink API for session event handling.
AI rationale
The scanner’s credential signal resolves to WalletLink session authentication within a crypto payment and wallet integration SDK. The manifest has no install hook, and the public checkout initialization requires application-supplied payment details and a publishable key.

Decision evidence
public snapshotAI called this Clean at 94.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- The manifest routes imports to dist/lydian.js and declares only a prepublishOnly guard, not an install hook.
- The entry file imports the SDK bundle; its public initialization method requires payment details and a publishable key.
- The flagged Authorization header is Basic auth built from a WalletLink session ID and secret and sent to the configured link API for event handling.
- The WalletLink API is set to https://www.walletlink.org, alongside Coinbase WalletLink service URLs; no unrelated credential collector was identified.
