CCE Cash note: Declining verification: understand the documented refund path and network fee. A KYC-triggered refund and a rate-expiry refund are different cases even if both can involve network fees. Keep the order context clear.
CCE Cash note: Five checks before integrating a cross-chain exchange API. Integration quality is mostly about state handling, not just sending a request. A good API wrapper makes waiting, errors and network mismatches visible.
