Very cool! Am I understanding it correctly that only the app sees the secret key, and that your modified neptune-core only sees a `ProofCollection`-backed transaction? If that understanding is correct, that seems like a great architecture.

One small thing I would change: Instead of using `Transaction` to send to the server, you could use `TransferTransaction` to get a type guarantee that the `PrimitiveWitness` (which contains secret key material) is never seen by the server.

Thank you for your prompt response.  
The Wallet APP can only send ProofCollection at this stage.  
Additionally, we’re evaluating whether using TransferTransaction to construct Transaction could significantly reduce bandwidth usage and accelerate network propagation. However, I haven’t yet identified a viable approach to implement this.
