According to CoinMeta, KuCoin announced the launch of KuCoin 5.0, deploying AI Assistant 5.x and a system internally referred to as KIA. This system is aimed at over 45 million users worldwide and can pause AI analysis, recommendations, and task execution that rely on unreliable data during extreme market conditions or large-scale liquidations. The person in charge of KuCoin AI Lab, Logan Xie, stated that KIA classifies inputs based on their credibility, and implements source verification, context isolation and cleaning, as well as context lifecycle management. AI decision-making assistance is isolated from the backend execution logic; the trading system is responsible for authorization, verification, and execution to prevent unauthorized operations. KuCoin 5.0 also introduces a unified trading account for users of VIP1 and above, using KCUSD as collateral to integrate spot, leveraged, and contract trading. It also supports direct use of Earn by sub-accounts without the need for manual transfers, and upgrades the personal center, sub-account control, cross-device candlestick charts, and color vision accessibility modes.
