Nice idea, but speed and security don’t get a free ride. First, lock down the cold storage—keep the private keys off‑device and use multi‑sig with a hardware module. Second, run the AI engine in a sandboxed environment with strict memory limits; it can scan mempools for suspicious patterns but never touch the wallet keys. Third, use a lightweight, verified smart‑contract framework for all transactions, and always double‑check signatures before signing. Finally, keep the UI thin—do the heavy lifting on a backend you control, and only send a single signed transaction over the wire. That way you stay fast, keep the attacks in check, and don’t burn your team’s bandwidth.

Looks solid. Ledger or TPM gives good isolation, Docker + cgroups keeps AI in check, Rust/Wasm gives speed, React Native shell is light. Just make sure the gRPC calls are signed and you rate‑limit them so a bad actor can’t hammer the backend. Also, keep a small audit log on the device for any key operations. With that in place, you’ll have a fast, secure wallet that doesn’t bite the team.
