Starknet curve libraries

Hello everybody,
I’m working on integrating Starkex into Trust Wallet, and I’m looking for the Starknet Curve implementation either in C++ or Rust (preferred).

What is the status of starknet-crypto?
Has the StarkWare team audited it internally?
Do you plan to request an external audit?

As far as I can see, Cairo VM (currently written in Python) is going to be replaced by cairo-vm (Rust implementation) that uses the starknet-crypto inside.
