Acala and aUSD Updates 

October 25, 2022

[Bette] Hello everyone, thanks for tuning in. It's been two months since our incident that happened on August the 14th the aUSD incident, but in between there's actually a lot has happened and a lot the team has been doing behind the scenes.

There were a lot of sleepless nights and a lot of hard work, long hours, to be able to collectively turn this whole incident around. Right now it's a more positive outlook for Acala and hopefully we can share a bit more detail on the incident, as well as where we're heading and also other information that we have with everybody

Overview from Bette

[Dan] Bette can you maybe just kick us off with just a high level summary of what happened the last couple months?

[Bette] I think it's worth recapping exactly what happened at the incident and also how the response were, so let's get started. So first of all, as many of you followed us on social media or various other channels, the incident happened on August the 14th, about two months ago, and that resulted in a significant number, three billion, aUSD erroneously minted.

However ultimately eventually, as the incident currently has concluded and Acala recovered, only 5.8 million aUSD circulating required to be re-collateralized. Acala Foundation used its own funds to borrow aUSD through collateralized debt position (CDP) and to re-collateralize the full amount of 5.8 million dollars, resulting in every single aUSD out there circulating being fully collateralized and backed. Then, the remaining were burned and also dealt with info via a series of community governance votes. The root cause of the incident was a vulnerability in the DEX saving code that is part of the incentive palette, and the fix of the vulnerability was reviewed by our security partner and also applied via a runtime upgrade after the incident. 

So at this time, we are quite happy to say Acala is fully recovered, same with aUSD, as all services are resumed and every single aUSD circulating on chain is fully collateralized, meaning they are backed by 100% or more collateral assets. Acala DEX pools are also recapitalized by the Acala Foundation. So, as the fundamentals of aUSD are sound and solid, we believe that aUSD is on its way to peg and certainly you know that's one of the topics today that we can discuss a little bit more. But overall, we are recovered and I really appreciate everybody's patience because it's been two months. But it is a very significant event where everybody worked together and all the partners, the community, the core team, many independent devs participated and helped to turn this whole event around, and now we are fully recovered. Of course for everything that I mentioned and what I’ll explain later, there are reports that we've published and also blogs that we've released that you can use to actually verify and also go into a lot more detail than what I have just said.

Incident Recap

[Dan]  I know there's a lot more detail specifically around the incident and how that exactly happened. There may be some people who maybe read parts of blogs or maybe haven't read much at all as far as what happened exactly, so can you kind of briefly explain the incident itself and how that went down?

[Bette] So for those of you who followed really closely and read every blog and every line that we published, bear with me and for others, here is a summary of what happened. As I mentioned, the incident resulted in a significant amount of aUSD erroneously minted specifically for the iBTC and aUSD reward pool. After that happened, 16 LP contributors (liquidity providers) that we identified claimed their rewards and subsequently received the ‘error mints’. Some of these LP contributors repeatedly added new liquidity into the pool with the claimed aUSD, and then resulted in more aUSD being erroneously minted. Then some of these LP contributors exchange the ‘error mints’ they received for other tokens. So they exchanged it for DOT, iBTC, INTR, etc in the Acala Swap. 

Some of them transferred the aUSD error mints and also those error mint-swapped tokens like DOT to other xcm-connected chains such as Polkadot, Moonbeam, Interlay,  Astar, as well as centralized exchanges. Then their swapping of the error mints with other tokens actually led to a huge disruption in the Acala Swap ratios of aUSD with other tokens in the pools as you can imagine. 

Then a number of other accounts acquired aUSD error mints at a significantly disrupted exchange ratio and some of these users repeatedly swapped more aUSD error mints as the imbalance of the pool grew over time. They then transferred a significant amount of aUSD to other xcm connected chains and CEX. That's how, only after a very short period of time, that 3 billion aUSD were actually minted in total and many of those actually flowed into many different accounts as well as some of them that flowed into different parachains and exchanges.

So that was the incident and the things that have happened in a little bit more detail. Of course there's also a series of trace reports that we published that tells you the exact story of how this actually happened, exactly which accounts were involved, how the flow of aUSD happened on-chain, as well. For those who are interested, you will be able to dig deeper and then find the story a bit more from there.

The Response

[Dan] Next I think it makes sense to get into a little bit around what was the overall response to the incident. Could you go into a bit more detail around what happened after what you just explained?

[Bette] So, initially once this was notified, then the first thing was to prevent further error mints, and also prevent further swaps with the disrupted ratio and also outflow of error mints into other chains. A number of urgent governance votes were passed to firstly reset the misconfiguration and also pause modules and functionalities relevant to this incident. So for example, incentive pallet, DEX, honzon protocol, oracle pallet, and also later on the LDOT instant redeem, non-ACA token transfers, XCM transfer out, EVM+, etc. modules were all paused post after the incident.

Then the Acala blockchain itself - so this is an interesting point for those who didn't notice - the Acala blockchain itself was never paused or halted completely and this of course is unique to the Acala network and also powered by substrate. In such that you know the risk and also impact of an incident can be isolated on-chain via governance without halting the entire network. So during the incident, for example, liquid staking and also stableswap pools were still operating and people were still doing what they normally would do there, while these other impacted modules were paused temporarily. Right after those immediate responses, the first thing was to figure out what happened, so a number of trace reports were published in the following days and weeks - some of those are really hard work - to review the full extent of the incident. We have received much support from our friends and partners during this time. 

For example, experts like chainalysis came forward proactively to support our effort and then we eventually developed our own algorithm and tooling that is capable of tracing the flow of every single aUSD error mint and every address that was involved in the incident. All the details were published and shared with everyone and all are verifiable on chain. Without a trace, no decisions could have been made rationally and precisely to help resolve the issue.

Then after that a number of community proposals and votes were then passed to resolve and also burn the error mints. The remaining 5.8 million aUSD that were still circulating error mints were re-collateralized, so, fully backed by collaterals by the Acala Foundation. As I also mentioned, the pools were particularly imbalanced during the incident due to the swaps that happened, and those pools were also re-capitalized by the Acala Foundation by injecting its own funds in DOT, iBTC, ACA and INRT tokens.

Acala Foundation continues working with legal, law enforcement, and various partners to retrieve and return all aUSD error mints and error mint-swapped tokens to the protocol. Currently, some assets are frozen on-chain via community governance vote, and some assets are frozen in a number of CEXs.

Phased Approach to Resuming Operations

[Dan] so you've talked through kind of what happened and then what the response was. I'm sure many people watching know that operations on Acala have fully been resumed recently but we took a specific approach to doing that. So can you kind of walk through it and remind people of what the approach was to resuming operations on the network after all of this?  

[Bette] Resuming operations was executed in a phased approach as recommended to protect LPs, Vault owners and users in general. In Phase 1, LPs could withdraw liquidity at the pre-incident level without any trading or fluctuation of prices. In Phase 2, trading was opened, vault owners could manage vaults and keep them safe before market price feeds via oracles resumed at phase 3 to avoid liquidation. In Phase 3, oracle, liquidations and remaining services were resumed. We are humbled by the support and help we have received during this process, for example, Gauntlet our risk auditor has been standing by us helping with monitoring risks and providing recommendations. 

aUSD Peg

[Dan] So now let's move on to I guess more of an ongoing situation so I think a lot of people have questions around aUSD and then the peg specifically, so could you just talk a little bit about the one dollar peg of aUSD?

[Bette] Yeah definitely. I think this is probably the most discussed, so it's worth probably spending a little bit of time explaining some context and also maybe some observations of the market and where things might be going as well. 

So first of all where does aUSD's value come from? So aUSD’s hard value is determined by the collaterals backing it. Basically every aUSD circulating is fully collateralized. When I say that, what do I mean? So that literally means every aUSD can be repaid to a vault and 100% or more collateral assets can be withdrawn from it. So this means they are fully collateralized. We are currently at that stage such that you have no bank run risk at all. This is the current state and the hard and true value of aUSD. Of course our risk partners, experts like Gauntlet, who is now focused more on providing parameter recommendations to balance market volatility risk and capital efficiency, and not at all about bank run and everything else because we are fully collateralized. So that is the context that we should all be aware of. It is very different from other types of the stablecoins, especially like algorithmic stablecoins, in that sense.

The second thing is addressing the elephant in a room, I guess. So some people may be very concerned about the peg or market price of aUSD. And, what is the market price? So we have the hard value or high price that how much physical collaterals you can receive from one aUSD - that is the hard value. But there's also a trading price. So when you see there's a DEX that's being traded on Acala and then of course there's also DEXs on Moonbeam as well. The market price is the face value of aUSD and it's driven by market conditions and also forces like supply and demand. So as a decentralized stablecoin, it's by design the face value will fluctuate based on market conditions. It never pegs exactly to one all the time. So it always fluctuates based on where things are at, depending on supply and demand, especially as we are in a special case. In a normal case, then it probably would fluctuate in a different pattern or at a different price level versus where we are currently now. 

So we are in a special situation right now in a number of ways. Our own situation, but also a slightly macro situation as well. So in our case, a few million circulating aUSD error mints are now fully collateralized so they're all worth their backing. So they're all worth the full amount of the collateral and then they are kind of floating back into the market. Then at the same time, well currently the crypto market and the macro economy are also in a turmoil situation as well. So as you know, a rational person would expect in such conditions the organic pegging process will take time, so that's reasonable to expect. However, if you combine the context that I've provided and also the current condition, some people might be smiling now, because every circulating aUSD is fully collateralized. The fundamentals of aUSD are sound and solid, which is verifiable on-chain. So don't trust what I said, just look on-chain and figure it out. It could be a good opportunity there to obtain aUSD at a low cost to repay vaults or arbitrage as it eventually pegs, but of course, that is not financial advice and please do your own research. So that is it about the peg - it will peg eventually and organic pegging will take time, but there's obviously opportunities in that as well.

Updates on Incentives and 

Loyalty Program for LPs

[Dan] This is a quick question but something that we've been getting from the community recently around the Acala app, specifically incentive programs, loyalty programs. Can you talk a little bit about the current state of that and what people can expect?

[Bette] Yeah sure, so the Acala Apps have been providing messages on what services were paused and what services have resumed. So if you log on again, you should be able to see in the top right corner everything is resumed now, and you should be able to see your portfolio as well as access all the services available. There were discussions about the loyalty program. I think technically that can be paused, so that everyone can actually withdraw their rewards, as currently all the incentives are paused and will still be in that situation for a while.

So I think the loyalty program there would be able to be paused. However, there's a technical dependency. There is a technical upgrade that is required before the loyalty program can be paused. That is coming up as well, so in the next probably days or weeks the upgrade will be coming our way. So this upgrade includes substrate upgrades that we didn't do during the incident and then there's also some cleanups, small fixes you know after the incident. Then the upgrade basically will put both Karura and Acala in a level playing field. So then we can start other new features or other sorts of improvements that we want to do. So that's the status of that.

What’s Next for Acala

[Dan] So we're following a bit of a kind of past present and future structure here so can you wrap us up with what people can expect going forward from Acala in the next few months and going into next year?

[Bette] While Acala is in the process of resuming services, it remains as one of the networks to have top trading activities and xcm cross-chain activities in the Polkadot ecosystem. Looking forward, there are a number of initiatives on the roadmap to further strengthen the security of the Acala network; technically it’s unique to Acala and substrate that risks and impacts of incidents can be isolated on-chain via governance without halting the rest of the network, further research and development will be needed to improve the proactive detection and isolation of abnormal activities, especially in a cross-chain environment.

Acala continues to march towards the next evolution of DeFi & Hybrid Finance with our partners and ecosystem, to provide a more compliant, open, transparent, efficient and safer platform for mass adoption through integrations such as with Alluvial & the Liquid Collective to provide institutional liquid staking services that ultimately will onboard non-crypto users for crypto experiences, and integration with Acala-native DeFi innovator Tapio, a synthetic asset protocol that brings unified staking and other derivative standards of base layer assets such as DOT; they have already launched their first product tDOT, and just received a $4M funding round from notable backers like Polychain, Arrington, Spartan and Longhash. The bear market is the best time for builders like ourselves to focus on the fundamentals, double down on the native DeFi innovations and our unique positions with HyFi integrations, to be ready to bring the mass market onboard and deliver real value.

Conclusion

[Bette] We appreciate everyone’s patience and support to help us get to this point, and it’s certainly a much happier place right now. But of course, everyone is very much humbled and we talked to a lot of partners during this process and and also other projects that have been through similar situations for us to be able to turn around  in a three billion situation with only a 5 million or so scratch that the Acala Foundation are able to step up to take on is quite a turnaround. But that is only the tip of the iceberg there's a lot more  sort of initiative, the technical upgrades, as well as a lot of work that has gone into making this happen and also more importantly is how in the future collectively we can up-level the security, especially in a crosstream world, as we progress. So expect a lot more hardcore development to be done and a lot more  grinding and working from our side. So thank you so much for everyone's support and patience. Appreciate it.

分享实录——双语版

Bette：大家好，感谢大家的参与。自从 8 月 14 日 aUSD 事件发生以来已经有两个月的时间了，但其实这期间实际上发生了很多事情，团队也在幕后做了很多事情。

我们经历了很多不眠之夜，通过许多非常有挑战性以及长时间的工作，我们与社区才能共同扭转整个事件。现在，Acala 的前景已经变得乐观，现在我将会分享更多关于这起事件的细节，以及我们未来前进的方向，以及我们向所有人提供的一些其他信息。

总览

Dan：Bette，能不能先给我们简单总结一下过去几个月发生的事情?

Bette：我认为有必要回顾一下事件发生的具体情况以及当下的反应，那么让我们开始吧。

首先，正如你们中的许多人在社交媒体或其他渠道上所看到的内容一样，这个事件发生在8月14日，大约两个月前，导致 30亿 aUSD 被错误铸造。

然而最终，随着事件的结束和 Acala 链上功能的恢复，只有580万 aUSD 流通需要重新抵押。Acala基金会用自己的资金通过债务抵押头寸(CDP)借入 aUSD，对这部分 aUSD 进行重新抵押了 USDC，使得流通的每一个 aUSD 都得到了充分的担保和支撑。然后，剩下的被销毁，并通过一系列社区治理来进行投票来处理信息。事件的根本原因是 DEX SAVING 代码中的一个漏洞，这是激励模块的一部分，我们的安全合作伙伴审查了该漏洞的修复方式，并在事件发生后通过 Runtime 应用升级完成该漏洞修复。

所以在这个时候，我们很高兴地说，Acala已经完全恢复了，aUSD 也是一样，因为所有相关的服务都恢复了，链上流通的每一个 aUSD 都是完全抵押的，这意味着它们有超过 100% 的抵押资产支持。Acala DEX 池子也由 Acala 基金会提供资金进行重组。因此，由于 aUSD 的基本面现在是健全和稳固的，我们相信 aUSD 正在与美元回复锚定的道路上，当然你知道这是今天我们可以多讨论一点的话题之一。但总的来说，我们已经恢复了，我非常感谢大家的耐心，因为已经两个月了。但这是一个非常重要的活动，每个人都在一起工作，所有的合作伙伴、社区、核心团队和许多独立开发者都参与其中，帮助扭转了局面，现在我们完全恢复了。当然，对于我所提到的一切以及我稍后将会解释的，我们已经发布了一些报告和我们发布的博客，你可以使用相关数据链接进行实际验证，也可以了解更多我刚刚没提到的细节。

事件回顾

Dan：我知道关于这一事件还有很多具体的细节，以及它究竟是如何发生的。有些人可能会读部分博客，或者根本没有读过关于到底发生了什么，你能简单解释一下事件本身和事情的经过吗?

Bette：对于那些密切关注并阅读我们发布的每一篇博客和每一行文章的人，请原谅我和其他人，接下去我会介绍所发生事情的一个总结。正如我所提到的，该事件导致了 iBTC 和 aUSD 池错误地铸造了大量 aUSD。在这之后，我们确定了 16 名 LP 贡献者(流动性提供者)领取了他们的奖励之后收到了“错误铸造”。这些 LP 贡献者中的一些人不断地用获得的 aUSD 向池中添加新的流动性，然后导致更多 aUSD 被错误铸造。然后，这些 LP 贡献者中的一些人将他们收到的“错误铸币”交换为其他代币。于是他们在 Acala Swap 中换成了DOT, iBTC, INTR等。

其中一些将 aUSD 的错误铸币和那些利用错误铸币换取代币(如DOT)并转移到其他 xcm 连接的链，如 Polkadot、Moonbeam、Interlay、Astar 以及 CeX。然后他们将错误的 aUSD 与其他的交换，实际上大量导致了aUSD与池中其他资产的 Acala 兑换比率被巨大破坏。

然后，一些其他账户以一个明显错误的兑换比率获得了错误铸造的 aUSD，随着池子的不平衡随着时间的推移不断增长，其中一些用户反复交换更多的错误的 aUSD。并他们将大量的 aUSD 转移到其他 xcm 连接的链与 CeX。这就是为什么，在很短的时间内，总共有30亿 aUSD 被铸造出来，其中很多流入了不同的账户，还有一些流入了不同的平行链和 CeX。

这就是这个事件和已经发生的一些细节。当然，我们也发布了一系列追踪报告，告诉你这是如何发生的，具体涉及哪些账户，aUSD的流动是如何在链上发生的。对于那些感兴趣的人，你将能够深入挖掘，然后从那里找到更多的故事。

事件应对

Dan：接下来，我认为有必要讨论一下人们对这一事件的总体反应。你能再详细谈谈你刚才解释之后发生的事情吗?

Bette：最初当我们发现这个事情发生之后，首先要做的是防止进一步的错误铸造，也要防止在 Swap 中以错误比率的进一步交易以及防止错误铸造流入其他链。随后，通过了一些紧急治理投票，首先重置错误配置，并暂停与此事件相关的模块和功能。例如，奖励模块、DEX、honzon协议、oracle 模块，以及后来的 LDOT 的即时兑换、非 ACA 资产转账、xcm 转账出去、EVM+ 等模块都在事件发生后被暂停。

然后 Acala 链本身有一个有趣的点很多人没有注意到，就是 Acala 链本身从来没有完全暂停或停止，这是 Acala 网络独有的也得益于 Substrate 框架。因此，用户就可以通过治理在链上隔离事件的风险和影响，而无需停止整个网络。所以在事件期间，比如流动性质押模块（Liquid Staking）和 ACA 转账仍然在运行，人们仍然在做他们通常会做的事情，而其他受影响的模块被暂时暂停。就在这些即时回应之后，第一件事就是弄清楚发生了什么，因此在接下来的几天和几周内发布了许多追踪报告——其中一些真的很辛苦——以全面审查事件的范围。在此期间，我们得到了朋友和合作伙伴的大力支持。

例如，Chainalysis 等专家主动站出来支持我们的工作，然后我们最终开发了自己的算法和工具，能够跟踪每一个aUSD被错误铸造的流程和事件中涉及的每个地址。所有的细节都被发布和分享给了每个人，所有的细节都可以在链上验证。没有痕迹，就不可能做出理性而准确的决定来真正帮助和解决问题。

之后，一些社区提案和投票被通过，以解决和销毁错误的铸币。剩下的 580 万 aUSD 错误铸币虽正在流通，但已经被重新抵押，也就是完全由 Acala 基金会担保。正如我还提到的，由于 Swap 里发生了资产交易，这些交易池在期间特别不平衡，这些池也由 Acala 基金会将其自己的资金注入 DOT、iBTC、ACA 和 INRT 来重新恢复正常。

Acala 基金会将继续与法律、执法部门和各种合作伙伴持续保持合作，检索并将所有 aUSD 错误铸币和错误铸币交换资产返回到协议中去。目前，一些资产通过社区治理投票在链上冻结，一些资产在多个 CeX 被冻结。

阶段性恢复

Dan：我相信很多人都知道 Acala 的行动最近已经完全恢复，但我们采取了具体的方法来做到这一点。所以你能简单介绍一下并提醒大家在经历了这一切之后恢复网络运行的方法是什么吗?

Bette：恢复操作按照建议的方法分阶段执行，以保护 LPs、Vault 所有者和普通用户。在第一阶段，流动性提供者（LPs）可以在没有任何交易或价格波动的情况下，以事件前的价格比率提取流动性。在第二阶段，交易已经开放，债仓（Vault）所有者可以管理债仓，并设置在第三阶段恢复 Oracles 的市场价格，确保债仓所有人的资产安全，以避免清算。在第三阶段，Oracle、清算和剩余的服务恢复。在这一过程中，我们得到了很多支持和帮助，例如，我们的风险审计伙伴 Gauntlet 一直与我们站在一起，帮助我们监控风险并提供建议。

aUSD 锚定

Dan：那接下去一个问题，这是一个持续的情况，我想很多人对 aUSD 有疑问，然后是具体的锚定逻辑是什么？能谈谈 aUSD 与 1 美元之间的锚定吗?

Bette：肯定是的。我认为这可能是讨论最多的，所以可能值得花一点时间解释一些背景，也可能是一些对市场的观察，以及事情的走向。

首先 aUSD 的价值从何而来?因此 aUSD 的价值其实是由支撑它的抵押品决定的。基本上每一个流通的 aUSD 都是完全抵押的。这意味着如果想取出100% 或更多的抵押资产，那么每一个 aUSD 都需要偿还给 Vault。也就是说 aUSD 是完全抵押的。我们目前处于这样一个阶段，你完全没有银行挤兑的风险。这是目前的状态，也是aUSD的硬支撑和真实价值。当然，我们的风险合作伙伴，像 Gauntlet 这样的专家，现在更专注于提供参数建议，以平衡市场波动风险和资本效率，而不是银行挤兑和其他任何事情，因为我们是完全担保的。这是我们都应该知道的情况。在这个意义上，这与其他类型的稳定资产非常不同，尤其与算法稳定资产是有很大的区别。

我想，第二件事是解决房间里的大象。因此，有些人可能非常关心 aUSD 的挂钩或市场价格。市场价格是多少？首先你能从每一枚 aUSD 背后获得超额支撑的抵押品，这就是硬价值。但也有交易价格。所以当你看到 Acala 有一个 DeX 在交易，当然 Moonbeam 上也有 DeXs。市场价格是 aUSD 的面值，它受市场条件和供需等因素的影响。所以作为一种去中心化的稳定币，它的面值会根据市场情况而波动。aUSD 从来没有完全固定在一个点上。所以 aUSD 总是会有波动，这取决于市场上的供给和需求（特别是我们目前处在一个特殊的情况下）。在正常情况下，aUSD 可能会以不同的模式或不同的价格水平略微波动。

所以我们现在在很多方面都处于一个特殊的情况。其中包括我们自己的情况，当然还有一些宏观的情况。所以在我们的例子中，现在流通的数百万 aUSD 错误铸造全部都有抵押的，所以这些都有足额的价值支撑。所以 aUSD 的价值相当于抵押品的全部金额然后它们又回到了市场上。与此同时，目前加密货币市场和宏观经济也处于动荡之中。你们知道，理性的人会认为在这种情况下自然挂钩的过程需要时间，这是合理的预期。然而，如果你结合我提供的背景和当前的情况，每一个流通的 aUSD 都是完全抵押的。aUSD的基本面是稳健的，是链上可验证的。哪怕不要相信我说的，大家看看链上的东西就知道了。这可能是一个很好的机会，以低成本获得 aUSD 的机会，以偿还债仓或套利，因为 aUSD 将最终会挂钩，但当然，这不是财务建议，请自己做研究。这就是关于 aUSD 挂钩的问题，它最终会自然挂钩，但需要时间，显然也有机会。

关于激励与忠诚奖励

Dan：这是一个简单的问题，但我们最近从Acala应用的社区中得到的一些东西，特别是激励计划，忠诚计划。你能谈谈目前的情况吗?人们可以期待什么?

Bette：是的，当然，所以Acala应用程序一直在提供哪些服务被暂停和哪些服务已经恢复的消息。所以如果你再次登录，你应该可以看到在右上角写着一切都恢复了，你应该也可以看到你的资产组合里访问所有可用的服务。而有关于忠诚计划的讨论。我认为从技术上讲，这是可以暂停的，这样每个人都可以领取他们的奖励，因为目前所有的激励措施都是暂停的，而且还会持续一段时间。

因此，我认为忠诚计划是可以暂停的。然而，这是一种技术依赖。在暂停忠诚计划之前，需要进行技术升级。这也是即将到来的，所以在接下来的几天或几周内，升级将会到来。这次升级包括我们在事故中没有做的 Substrate 升级，还有一些数据清理以及事故后的小修复。那么升级基本上会让 Karura 和 Acala 处于一个公平的竞争环境中。然后我们就可以开始我们想做的其他新特性或其他类型的改进。这就是目前的状态。

Acala 的下一步

Dan：所以我们遵循的是一种过去、现在和未来的结构，你能给我们总结一下人们对 Acala 未来几个月和明年的期望吗?

Bette：虽然Acala正在恢复服务，但 Acala 仍然是 Polkadot 生态系统中拥有最活跃交易活动和 xcm 跨链活动的网络之一。展望未来，路线图中有许多倡议，以进一步加强 Acala 网络的安全性，从技术上讲，Acala 和 Substrate 的独特之处在于可以通过治理，在链上隔离事件的风险和影响，而不停止网络的其他部分，需要进一步的研究和开发来改进异常活动的主动检测和隔离，特别是在跨链环境中。

Acala 将继续与我们的合作伙伴和生态系统一起朝着 DeFi 和混合金融的下一个发展方向迈进，通过与 Alluvial & Liquid Collective 的整合，将会为大规模应用提供一个更合规、开放、透明、高效和安全平台，以提供机构的流动性质押服务，最终将在非加密用户上提供加密体验，并与 Acala 本地的 DeFi 创新者 Tapio 合成资产协议进行整合，为基础层资产(如DOT)带来统一的 Staking 以及其他衍生标准。他们已经推出了第一款产品 tDOT，并刚刚获得 Polychain、Arrington、Spartan 和 Longhash 等知名投资方的400万美元融资。熊市是像我们这样的构建者关注基本面的最佳时机，通过本地的 DeFi 创新以及我们与 HyFi 集成的独特位置上付出加倍努力，以做好将大众市场带入加密领域的准备，并交付真正的价值。

结论

Bette：我们感谢所有人的耐心和支持，帮助我们走到这一步，目前我相信这将会是一个更好的境地。当然，所有人都很谦卑，在这个过程中我们和很多合作伙伴谈过，也和其他经历过类似情况的项目谈过，我们能够在一个 30 亿美元的情况下，用 500 万左右的缺口来扭转局面，Acala 基金会能够快速反应并承担，这是一个相当大的转变。但这只是冰山一角，还有更多的主动性，技术升级，以及大量的工作来实现这一点。

更重要的是，未来我们如何集体提高安全水平，特别是在一个跨链的世界，随着我们的进步。所以我们期待着更多硬核开发的完成，以及完成更多任务和工作。非常感谢大家的支持和耐心。很感激。
