As winners of the ETH hackathon in 2021, the Hackless team is now releasing the beta version of Anti-Sandwich – a gateway to safe and efficient swapping of crypto assets, avoiding public mempools and consequently, getting ‘sandwiched’. This solution is already working well for play-to-earn platforms and now it’s available to a wider audience.

The risks of DeFi

Financial freedom is simultaneously the biggest groundbreaker and risk of DeFi. The biggest risk and groundbreaker of DeFi is financial freedom. However, users can also take control of their assets through decentralised exchanges. They are also responsible for the security of their funds. The industry is still in its infancy, which means that there is a limited market. Hackless is a DeFi security provider of advanced solutions to protect projects and individual users from hacks, exploits and attacks of different kinds, as well as helps migrate funds from already hacked protocols and wallets.

A sandwich attack is a relatively new but increasingly frequent and an already well-known type of front and back running attack. According to a report published by TarLogic, between May 2020 and April 2022, there were a total of 457,691 sandwich attacks detected with an average ROI above 4%. The most profitable attack ever was spotted in May 2021 having taken 56 ETH worth of $200,000 at that time. It was possible in only two transactions.

Sandwich attacks explained

Sandwich attacks include both front-running and back-running tactics applied over buy transactions sent to DEX. This is done by watching a mempool for suitable transactions. Once an opportunity presents itself, attackers buy the same token first, and then sell it after the transaction has been completed.

When breaking down a sandwich attack, three clear stages are seen:

1. An attacker detects a high-value transaction in the mempool and puts a buy transaction to pump the asset price.
2. A user buys coins at a higher price.
3. The attacker sells coins pocketing the difference in price.

Choose the best Anti-Sandwich protection for you

Hackless enables each and every DeFi user to swap assets, avoiding public mempools. This allows you to send your transactions directly from DeFi to miners, rendering them inaccessible to exploiters.

The service is available on the Hackless website via an intuitive and easy to use widget. Connect your Metamask to the internet, choose the token and network, and then sign the transaction. Private miners will automatically submit it to you.

Anti-Sandwich for business

According to the REKT Database, DeFi protocols have lost $6 billion in total, due to scams, hacks, and exploits of different kinds, sandwich attacks included. Hackless has a solution that DeFi companies can use to provide extra protection and a better user experience.

Anti-Sandwich by Hackless is the best fit for blockchain projects in need of a fast and secure swapping widget. This solution is available now on Ethereum Smart Chain networks and Binance Smart chain networks.

With the Anti-Sandwich widget on the client’s website, users can easily swap project tokens without ever leaving the website. This makes it easier and safer for users and prevents any confusion or sandwich attacks. The widget is easily pluggable to any website via the NPM library, as well as customizable to brand design and feel.

10,000 $HKLS airdrop pool for early adopters

While the best perk is actually avoiding getting ‘sandwiched’ and losing your money, Hackless also encourages the most security conscious teams and folks by airdropping 10,000 HKLS tokens, giving referral bonuses and more.

Early adopters are the luckiest for sure – not only do they have a chance to try out the service free of charge, but also participate in the dedicated airdrop activity via Gleam.
