1inch Unveils Rabbithole: A Shield Against Sandwich Attacks in Crypto Trading

Understanding Sandwich Attacks

Let’s start with the elephant in the blockchain room: sandwich attacks. These crafty little scams involve a trio of transactions designed to exploit unsuspecting traders. Here’s how the sandwich filling works:

1. First, an attacker scouts the blockchain’s mempool—think of it as a waiting room for transactions—until they spot a high-value transaction that makes their eyes go all dollar signs.
2. Next, the attacker jumps in with their transaction, offering a higher gas fee. It’s like paying extra to cut the line at a concert. This ensures their transaction processes before the victim’s, artificially inflating the price of the asset the victim is buying.
3. Finally, after the victim’s transaction goes through, the attacker swoops in again, selling their coins at the now-inflated price, pocketing the difference and leaving the victim feeling a bit lighter in the wallet.

This scam is aptly named because it ‘sandwiches’ the victim’s transaction with two of the attacker’s own, hence the cosmic irony of being ‘squeezed’ out of your funds.

Introducing Rabbithole: Your New Best Friend

Enter Rabbithole, the shiny new tool from 1inch that aims to thump these sandwich attacks harshly back to the dark nether. Launched on November 25, it allows users to submit transactions directly to Ethereum nodes, skipping the mempool where attackers lurk like predators waiting to snap up unsuspecting prey.

To join the Rabbithole secret club, users need to switch the remote procedure call (RPC) endpoint in their crypto wallet. Once this is done, every swap made through 1inch will get the royal treatment of analysis from a clever private transaction routing algorithm, flagging any sandwich attack potential.

Why Should You Care?

What does this mean for you, dear trader? Well, according to a report by TarLogic, more than 60,000 Ether (ETH)—worth over $72 million at the time—vanished into thin air from sandwich attacks between May 2020 and April 2022. Protecting your investments is paramount, and Rabbithole offers a safer route.

From Developers to Regular Joe: The Usability Angle

Flashbots, another player in this dance of transactions, previously released a Python library allowing users to submit transactions directly to nodes, but without a user-friendly interface. 1inch aims to democratize this technology with Rabbithole by providing a consumer-friendly frontend, making it more accessible for everyday traders to protect themselves.

Continuously Evolving DEX Tools

Rabbithole is not the only feather in 1inch’s cap. With several notable upgrades including an Ethereum Layer 2 version on Optimism and a new router introduced back in November 2021, the platform shows its commitment to improving user experience and mitigating common trading risks.

So if you’re ready to step into the future of trading with an extra layer of security, consider hopping down the Rabbithole and trading smarter, not harder!
