[[File:Corrafinance.jpg|thumb|CORRA Finance]]Corra Finance is a service which enables the sale and purchase of NFTs. Their token used ChainSwap to exist on multiple blockchains, which required some funds to be stored in the smart contract hot wallet.

The ChainSwap bridge was hacked, and the attacker was able to obtain the tokens, which were sold. ChainSwap was able to negotiate the return of the tokens from the hacker.

This is a global/international case not involving a specific country.

== About CORRA Finance ==
"Corra.finance is a plug-and-play platform that enables the monetization of digital content using NFT technology." "Corra.Finance was announced on March 23, 2021." "We aim to gamify existing DeFi products by enhancing their yield through the use of exclusive NFT products sold on Corra.finance. The goal is to introduce new revenue streams, enhance user experience, and increase the interaction between users and existing DeFi products."

"Corra will enable the monetization of digital content through the creation of NFT. Instead of gaining likes from your photos on Instagram, you can sell them to your fans. Anyone can create NFT products, auction them, and monetize their ideas, words, digital content, products, and much more. Corra strives to push NFT use cases beyond just gaming and digital arts. The platform will introduce four new categories to curate NFT products: DeFi, digital content, social media, and non-profit. Users can create and list products for free without paying gas fees. Only when the users auction out a successful sale will the platform charge a fee, guaranteeing a profit to all NFT creators on Corra."

"ChainSwap is a bridge protocol that links the Ethereum and Binance Smart Chain (BSC) blockchains." "It supports Binance Smart Chain, Ethereum, Polygon, and Huobi Eco Chain." "The ChainSwap hacker identified and exploited a vulnerability in the ChainSwap smart contract. This vulnerability enabled them to steal and mint new tokens for various protocols that were using the bridge to trade across Ethereum and BSC."

Investigation by ChainSwap revealed "a bug in the token cross-chain quota code. The on-chain swap bridge quota is automatically increased by the signature node, which is intended to be more decentralized without manual control. However, due to a logical flaw in code, this led to an exploit by allowing invalid addresses which weren’t whitelisted to automatically increase the amount."

"Chainswap was attacked today. It is recommended to not add any liquidity to any pools until further notice."

"The attacker managed to take control of the projects’ BSC contracts by exploiting ChainSwap. The attacker minted tokens directly to their address, then sold them on BSC’s most popular decentralized exchange, PancakeSwap." "[T]he attacker used the PancakeSwap exchange to convert the stolen tokens to WBNB, DAI, and other tokens."

"Chainswap said it had already repurchased a small amount of the affected tokens from the market and returned the contract wallet. The rest will be paid out in full by the Chainswap vault." "ChainSwap team has now prepared and executed a compensation plan in consensus with the affected projects." "In order to bring everybody a more rigorous, efficient bridge, the next development model of ChainSwap will be adjusted to ensure maximum safety."

"According to their post-mortem and compensation plan, the ChainSwap team, with assistance from police and OKEx, managed to find the attacker’s email address and entered negotiations with them. These negotiations resulted in the return of Corra and RAI tokens."

"ChainSwap smart contract has been restored and the attacker has returned tokens to the ChainSwap team. Corra liquidity will restore within 1-2 weeks once the full restoration has been completed by ChainSwap."

"For now, Chainswap has temporarily closed its cross-chain bridge." "ChainSwap worked with the police and OKEx to identify the attackers, and managed to negotiate the recovery of Corra and Rai tokens. An initial email with the attackers suggested the attackers return $1 million."

“Sorry for the trouble, you sound genuinely like great people but money is money,” the attackers of the earlier exploit told ChainSwap.

"Chainswap compensated Corra for the breach. Bridge have been halted."

"ChainSwap is excited to announce that we have successfully integrated with Anyswap and Chainswap bridge is now live. We thank our community for its patience during the last few weeks."

This is a global/international case not involving a specific country.

The background of the exchange platform, service, or individuals involved, as it would have been seen or understood at the time of the events.

Include:

* Known history of when and how the service was started.
* What problems does the company or service claim to solve?
* What marketing materials were used by the firm or business?
* Audits performed, and excerpts that may have been included.
* Business registration documents shown (fake or legitimate).
* How were people recruited to participate?
* Public warnings and announcements prior to the event.

Don't Include:
* Any wording which directly states or implies that the business is/was illegitimate, or that a vulnerability existed.
* Anything that wasn't reasonably knowable at the time of the event.
There could be more than one section here. If the same platform is involved with multiple incidents, then it can be linked to a main article page.

== The Reality ==
This sections is included if a case involved deception or information that was unknown at the time. Examples include:

* When the service was actually started (if different than the "official story").
* Who actually ran a service and their own personal history.
* How the service was structured behind the scenes. (For example, there was no "trading bot".)
* Details of what audits reported and how vulnerabilities were missed during auditing.

== What Happened ==
The specific events of the loss and how it came about. What actually happened to cause the loss and some of the events leading up to it.

== Total Amount Lost ==
The total amount lost is unknown.

How much was lost and how was it calculated? If there are conflicting reports, which are accurate and where does the discrepancy lie?

== Immediate Reactions ==
How did the various parties involved (firm, platform, management, and/or affected individual(s)) deal with the events? Were services shut down? Were announcements made? Were groups formed?

== Ultimate Outcome ==
What was the end result? Was any investigation done? Were any individuals prosecuted? Was there a lawsuit? Was any tracing done?

== Total Amount Recovered ==
There do not appear to have been any funds recovered in this case.

What funds were recovered? What funds were reimbursed for those affected users?

== Ongoing Developments ==
What parts of this case are still remaining to be concluded?

== Prevention Policies ==
Theoretically, decentralized finance will eventually result in hackers having exploited every vulnerability that exists. However, it's impossible to know when that will occur and if a contract is truly secure, as opposed to there still being an exploit that just hasn't been noticed yet. For any complex smart contract, it's impossible to prove security and plenty of fully audited contracts have been exploited.

In this situation, there was luckily not much taken, and it looks like it will be ultimately reimbursed. Platforms should, generally, be prepared for the full loss of all assets stored in hot wallets (including smart contracts). Assets that do not need to be accessed quickly should be stored securely in a simple offline multi-signature wallet.
