涉及知名机构参投项目的重大安全事件及资产迁移方案，直接影响持有者权益处理与后续交互路径，需重点关注官方公告以完成代币转换。
The YZi-backed bitcoin restaking firm BounceBit announced today that it is shutting down its blockchain after hackers exploited an authorization vulnerability and stole over $3.1 million of its BB token.
由 YZi Labs 支持的比特币再质押公司 BounceBit 今日宣布，在黑客利用授权漏洞并窃取超过 310 万美元的 BB 代币后，它将关闭其区块链。
BounceBit claims that between August 19 and August 20, attackers were able to move 286 million BB tokens out of nine of BounceBit Chain’s wallets without authorization.
BounceBit 声称，8 月 19 日至 8 月 20 日期间，攻击者未经授权从 BounceBit Chain 的九个钱包中转移了 2.86 亿枚 BB 代币。
Evmos stack caused exploit
Evmos 堆栈导致漏洞被利用
An authorization flaw in the vesting and lockup account module hosted by Evmos, and utilized by BounceBit Chain, seemingly led to the exploit.
据称，由 Evmos 托管并被 BounceBit Chain 使用的归属和锁定账户模块中的授权缺陷导致了此次漏洞被利用。
BounceBit says the attacker sent an estimated 254 million BB tokens to one “major” crypto exchange, almost 10 million BB tokens to another exchange, and 18.5 million BB tokens remain sitting in a consolidated address.
BounceBit 表示，攻击者将约 2.54 亿枚 BB 代币发送至一家“主要”加密货币交易所，将近 1000 万枚 BB 代币发送至另一家交易所，另有 1850 万枚 BB 代币仍停留在一个合并地址中。
We have identified an issue affecting BounceBit Chain and have paused nodes out of caution while we deploy a fix. BB transactions are temporarily unavailable.
我们发现了一个影响 BounceBit Chain 的问题，出于谨慎起见，我们在部署修复程序时暂停了节点。BB 交易暂时不可用。
This is limited to the chain itself, the CeDeFi app is not affected, and neither are smart contracts or vaults.
这仅限于链本身，CeDeFi 应用不受影响，智能合约和金库也不受影响。
No…
不……

BounceBit rules out network upgrade
BounceBit 排除网络升级可能性
BounceBit claims that it is sunsetting its blockchain after a technical review and will not be able to implement a network upgrade since it is built on the already discontinued Evmos infrastructure.
BounceBit 声称，经过技术审查后，它将关停其区块链，并且由于构建在已停用的 Evmos 基础设施之上，将无法实施网络升级。
It said, “Moving our fork onto a successor codebase would therefore not be a conventional upgrade, but a substantial re-platform requiring a full rebuild, re-audit, and revalidation before it could safely carry user assets again.”
该公司表示：“因此，将我们的分叉迁移到后继代码库并非传统意义上的升级，而是一次重大的平台重构，需要全面重建、重新审计和重新验证，之后才能安全地承载用户资产。”
BB tokens will now turn into BEP-20 tokens
BB 代币将转变为 BEP-20 代币
Every other BB token, bar the attackers, will be reissued as a BEP-20 token on BNB Chain. A snapshot of the block before the exploit will be used to determine the sum of BEP-20 tokens a user will receive.
除攻击者持有的 BB 代币外，所有其他 BB 代币都将在 BNB Chain 上重新发行作为 BEP-20 代币。将使用漏洞被利用前的区块快照来确定用户将获得多少枚 BEP-20 代币。
BounceBit also claims it has asked crypto exchanges to freeze specific addresses that won’t affect the funds of innocent users.
BounceBit 还声称，它已要求加密货币交易所冻结特定地址，这不会影响无辜用户的资金。

BB token holders were told that they won’t need to do anything and that they should be cautious of scammers offering help.
BB 代币持有者被告知无需采取任何行动，并应警惕提供帮助的骗子。
BounceBit raised $6 million in 2024 as part of a seed funding round co-led by Blockchain Capital and Breyer Capital. According to the Binance Square moderator “Tang Hua,” YZi Labs invested later in April 2024.
2024 年，BounceBit 作为种子轮融资的一部分筹集了 600 万美元，该轮由 Blockchain Capital 和 Breyer Capital 联合领投。根据 Binance Square 版主“Tang Hua”的说法，YZi Labs 于 2024 年 4 月下旬进行了后续投资。
