How testnet stays honest
TestExchange fills each trade at an EIP-712 quote signed by a keeper with the live mainnet price, valid for 10 minutes. So the Guard sees on testnet exactly what it would see on mainnet, and nothing can go stale.
The Binance Trading API refuses requests from cloud IPs (
40304 compliance restriction). Mainnet buy quotes therefore work from a home network or a local run, not from the hosted app in every region.
