Framework-agnostic build of the Funkit Connect SDK
AI Security Review
scanned 3d ago · by lpm-firewall-aiThe scanner’s credential finding resolves to Coinbase Wallet’s WalletLink session authentication: the session ID and key are sent to WalletLink’s own API. The manifest has no install hook, and the connection code belongs to the browser checkout SDK’s wallet flow.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
The flow is used as part of the wallet connection features when the SDK is used.
Impact
No unrelated credential collection or disclosure was found in the reviewed flow.
Mechanism
WalletLink builds Basic authentication from its session ID and key and uses it for requests to its own events API.
AI rationale
The scanner’s credential finding resolves to Coinbase Wallet’s WalletLink session authentication: the session ID and key are sent to WalletLink’s own API. The manifest has no install hook, and the connection code belongs to the browser checkout SDK’s wallet flow.

Decision evidence
public snapshotAI called this Clean at 97.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- The manifest describes a framework-agnostic checkout SDK and exports dist/index.js as its entry point.
- The manifest scripts are build, development, type generation, lint, and test commands; no install lifecycle hook is declared.
- The checkout entry point requires a browser and exposes createFunkitCheckout, so the flagged wallet code is part of SDK use rather than install-time behavior.
- The flagged Authorization value is built from a WalletLink session ID and key, then sent to the WalletLink API for its events flow.
- The bundled Coinbase Wallet SDK sets the WalletLink service URL to https://www.walletlink.org and loads or creates a WalletLink session for its connection.
