CoinEx founder Yang Haipo said the exchange is closing but highlighted its MPC-based dual-signature hot-wallet infrastructure as a security model worthy of industry adoption. The system uses separate business and wallet systems managed by independent teams, with both required to approve transactions. Each withdrawal or transfer must pass real-time risk reviews by both systems, preventing unauthorized asset movement if only one is compromised. CoinEx built its wallet-signing processes independently instead of relying on native node mechanisms, a project that took more than a year across nearly 300 supported blockchain networks.
