What is “sandwich trading” cryptocurrency?

Cryptocurrency trading bots are believed to earn hundreds of millions of dollars, if not billions.profit using a technique known in the industry as "sandwich trading".

According to a recent Fortune report, bots are using this tool to make huge profits in the Ethereum ecosystem.

In essence, the bot is programmed by developerssoftware to detect when another trader is trying to purchase a crypto asset on the blockchain, Ethereum or Cardano. The bot places an order for the same token, hoping to complete the transaction first and raise the price of the asset. The bot then "finishes the sandwich" by selling the token to the original trader at a higher price.

The report claims that developers have floodedthe Ethereum ecosystem by bots, earning a untold fortune at the expense of other traders. According to Bloomberg, this method has become so successful that it is becoming increasingly difficult for developers to use it due to the huge number of such bots.

Sandwich trading bots have spread to other blockchains, notably Solana, Polygon, and Avalanch, loading their networks and even causing congestion.

In January, Solana was forced to implement new developments to combat bot traders, including "flow control" measures.
