Countering sandwich attacks

DeFi Security Provider, Hackless, introduces a new tool to help combat sandwich attacks on BNB Chain and Ethereum. The solution allows to make safer exchanges by avoiding public mempools and sending transactions directly to miners.

Smooths out DeFi security

With the rapid development of decentralized exchanges and an ever-increasing number of hacks, it has become clear that security is something that needs to be improved immediately. While in traditional finance this has always been the responsibility of the business, in DeFi users can and should also contribute.

Hackless has designed security solutions, both for DeFi projects and developers, as well as individual users, to protect them from targeted exploits, which include sandwich attacks.

What is a sandwich attack?

Explorers started performing sandwich attacks not too long ago, but it has become a very common and profitable front-and-back-run strategy. As published in a TarLogic report, between May 2020 and April 2022, a total of 457,691 sandwich attacks were detected with an average return of over 4%.

When we take a closer look at this type of attack, we will see that if played smartly, the execution of just two transactions can bring an exploiter quite a significant profit. To do this, attackers typically monitor mempools looking for high-value transactions that can potentially be pinched. Once detected, the attacker creates a buy transaction for the same token before the transaction of a user to pump the asset price. This results in a user purchasing an asset at a higher price. Right after a user’s transaction has been executed, an attacker sells their coins, posting the difference in price.

Individual Anti-Sandwich protection for BNB Chain

If you want to trade assets on BNB Chain without the risk of getting squeezed and losing money, consider checking out Anti-Sandwich by Hackless. Not only does it provide a free tool that makes transactions invisible to hackers since they don’t appear in public mempools, it also offers a very simple interface and intuitive experience even for beginners. All you need to do is connect to your Metamask wallet, select the BNB Chain network and a token you wish to exchange and sign the transaction. Once signed, it will automatically be sent to private miners.

Anti-Sandwich for businesses running on the BNB Chain

Anti-Sandwich by Hackless best suited for blockchain projects that care about the user’s product experience. The solution has already proven effective for a play-to-earn platform that has integrated Hackless-customized widgets for its users.

The Anti-Sandwich widget offers some benefits for DeFi projects:

• Better user experience, without the user ever leaving the platform to exchange a project token.
• Leveraged security while fending off potential sandwich attacks during switching.
• Smooth integration via NPM libraryas well as brand adaptation.
