FX-aware Settlement Agent
This Python agent prices the route before it pays. Given a cross-currency settlement intent, agent.py reads three Pyth price feeds on Arc testnet — EUR/USD, EURC/USD, and USDC/USD — through pyth.py, and fx_oracle.py measures how far EURC trades from its euro peg, gating every decision on the oracle's confidence and freshness. The agent then routes each payment the cheaper way, buying discounted EURC via an on-chain swap or settling direct in USDC, rather than converting at naive spot. Settlement executes through a Circle Developer-Controlled Wallet wrapper in circle_wallet.py with server-side signing and a reconciliation memo attached to each transfer, while arc_client.py provides read-only JSON-RPC access to Arc for ERC-20 and wallet state.
