周末发生了个大事，Polkadot DeFi 的枢纽 Acala 拥有稳定币aUSD，被利用了大约 12 亿 aUSD。
CoinGecko数据显示，去中心化多抵押稳定币Acala Dollar（aUSD）已跌至0.00976832美元 24小时跌幅达99.1%，已严重脱锚。ACA跌至0.287577美元，24小时跌幅达10.8%。 据此前报道，Acala疑似遭黑客攻击，官方称Honzon协议的一个配置问题影响到aUSD，正通过一项紧急投票暂停操作。此后，它在其推特账户上解决了该问题，并解释说该问题已被确定为今天早些时候推出IBTC/aUSD 流动性池的配置错误。
99% 以上的错误 aUSD 仍保留在 Acala 平行链上，仅有小部分资产换成了 ACA，DOT 及 GLMR 等。目前，所有有关资产已禁用，相关 swap、xcm、honzon 功能与预言机模块也已经暂停，无需担心清算。我们将持续链上地址的追踪，并与社区分享结果，以促进社区提案和决策的制定，解决 aUSD 的错误铸币与锚定！
UST Hack 没有重复
这次黑客攻击让加密推特社区陷入了狂热，许多人猜测几个月前发生的 UST 情景重演。然而，它似乎与算法稳定币的崩溃没有什么相似之处，因为它被过度抵押了。
Acala 在其推特声明中解释说，错误铸造的 aUSD 立即将稳定币与原始价值的 70% 脱钩仍保留在其平行链上，从声明看来，这种情况似乎很快就会得到挽救。
在等待 Acala 社区集体治理决定解决错误铸造时，这些错误铸造的 aUSD 保留在 Acala 平行链上，以及这些交换的 Acala 平行链原生代币已被禁用。 该团队在声明中表示。
网络上的其他一些功能也已被禁用，等待治理投票以避免清算。Polkadot原生代币已显示出复苏迹象。
Acala 美元现在的走势如何？
根据 CoinmarketCap 的说法，aUSD 距离收回挂钩仅几美分，截至撰写本文时目前的交易价格为 0.86 美元。稳定币于今年年初推出，它在多抵押机制的支持下运作。它可以使用像 DOT 和 LCDOT 这样的硬币作为抵押品来铸造。
该团队还要求收到错误铸造的稳定币的人和白帽将其退回到它发布的某个地址，并宣布从黑客那里收到稳定币的每个地址都是已知的。但是这次事件对于波卡的影响还是挺大的，本来卡槽拍卖就没带起来热度，这次负面影响又给波卡发展的道路填了一堵墙。
今天的分享就到这里，后期会给大家带来其他赛道的龙头项目分析。感兴趣的可以点个关注。我也会不定期整理一些前沿资询和项目点评，欢迎各位志同道合的币圈人一起来探索。 来源：金色财经 |
