ChainCatcher 消息,Coinbase 发文介绍其用户资产保护机制,并表示未受到 Binance 此前热钱包安全事件影响,目前平台系统及用户资金均未受影响。

Coinbase 称,目前超过 99% 的用户资产存放在冷钱包中,热钱包仅保留满足用户日常提现和使用需求的少量资金,并根据存取款需求动态调整余额。其机构托管金库资产则全部采用冷存储,并在链上独立隔离。

在资金转移安全方面,Coinbase 采用分布式密钥保护、提现限额、异常活动监测及紧急停止机制。冷钱包私钥被拆分存储,签名过程中不会完整重构;热钱包生产环境的密钥签名服务也不允许单人独立访问。若发现异常交易或提现量激增,系统会触发调查和限额,必要时可通过关闭签名密钥暂停部分或全部资金转移。

Coinbase 还表示,用户资产始终由用户持有,平台按 1:1 持有资产,未经用户指示不会出借或挪用。截至 2026 年 9 月 30 日,Coinbase 平台资产规模达 3770 亿美元,持有现金及现金等价物 86 亿美元、投资性加密资产 22 亿美元。公司称,随着 AI 能力发展改变安全风险格局,将继续加大安全技术投入。
