According to Wu Blockchain, CoinEx founder and CEO Haipo Yang tweeted that CoinEx's hot wallet uses an MPC-based dual-signature solution, with one private key held by the business system and the other by the wallet system. All withdrawals and transfers must pass real-time risk control reviews by independent teams from both sides. Even if one system is compromised, assets cannot be stolen. This solution covers nearly 300 blockchains supported by CoinEx and took over a year to implement. https://(wublock123.com)/news/coinex-founder-ceo-hot-wallet-mpc-dual-signature-68998
