Is Begin: Bitcoin Cardano Solana Wallet safe?

Low risk

Begin: Bitcoin Cardano Wallet ships production API keys and service credentials in its extension bundle.

The shipped MV3 JavaScript contains hardcoded Begin API keys and third-party service credentials/tokens. The Begin API key is used as an Authorization header when the extension calls Cloud Run endpoints for device registration, device updates, dapp lookup/search, and rating submission. The bundle also includes credentials for Holafly, Drip, Deepgram, on-ramp, and Maestro services.

Part of this rating comes from analysis signals we haven't published as detailed findings yet.
