2.2 Security Upbit在遭遇3000万美元黑客攻击后，将99%用户资产转入冷钱包，超越法律要求，树立安全新标准，但高需求时大额提现或变慢。
Upbit是韩国主要的加密货币交易所，因其Solana热钱包遭遇重大黑客攻击、损失约3000万美元后，已将99%的用户资产转移至冷钱包。此次安全升级远超韩国法律要求的至少80%离线存储标准。Upbit的运营方Dunamu宣布，热钱包的资产暴露将降至接近零，绝大多数资金将由冷钱包保管，以最大限度降低未来被盗风险。公司已审查并升级钱包基础设施，加强内部管控，并将资产转移至离线状态以保护用户安全。尽管此举提升了安全性并树立了行业新标杆，但在高需求期间可能会导致大额提现变慢。Upbit承诺所有损失将由其储备金承担，用户资金依然安全。该策略预计将促使其他平台提升自身安全标准。
