Framework-agnostic build of the Funkit Connect SDK
AI Security Review
scanned 3d ago · by lpm-firewall-aiThe scanner’s credential finding maps to the Coinbase Wallet SDK’s WalletLink relay client, which uses session credentials for relay event requests. The manifest has no install hook, and the reviewed source does not show unrelated credential collection or exfiltration.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
WalletLink event operations when the wallet relay client is used.
Impact
No unrelated credential collection or transmission was identified.
Mechanism
The client authenticates to its configured linkAPIUrl using a Basic value derived from that relay session's ID and key.
AI rationale
The scanner’s credential finding maps to the Coinbase Wallet SDK’s WalletLink relay client, which uses session credentials for relay event requests. The manifest has no install hook, and the reviewed source does not show unrelated credential collection or exfiltration.
Network endpoints1
Configured linkAPIUrl (host is supplied to the WalletLink client)
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 exposes the bundled SDK through dist/index.js and declares no install lifecycle hook.
- The flagged Authorization header belongs to the bundled Coinbase WalletLink client, which creates Basic authentication from its session ID and session key and sends it to its configured linkAPIUrl for event operations.
Evidence against
- The static scanner flagged credential exfiltration, but the inspected credential flow is part of a wallet relay client and does not show collection of unrelated user credentials.
- No install-time script is declared in the package manifest.
