We started an audit of
@axol_io's PXE Bridge.
It exposes Aztec's shielded settlement to EVM intent solvers over JSON-RPC: solvers request note creation via a simple RPC call, and the bridge's embedded Aztec PXE creates the shielded note and generates the proof on their behalf, so solvers never need to run their own PXE or handle Aztec's private execution model themselves.
