# Arbitrage package

The arbitrage package would contain two, sometimes even three arbitrages, i.e., [this one](https://eigenphi.io/ethereum/tx/0x93d331ca38bcb540f13fbb9d47fe1272a11156c536bb212b5a82b8454383fa4c) identified by EigenPhi. Two arbitrages involving 3 tokens among 3 LPs combined together to rake profits in one transaction.

Usually, such action is to save the cost--gas fees--to finish two or more arbitrages. Another reason is to avoid being the victim of [Sandwich MEV](https://eigenphi-1.gitbook.io/classroom/mev-types/sandwich-mev). To successfully employ a strategy like this, traders would use [flashbots](https://github.com/flashbots/pm), the open-source project that would bundle transactions and send the bundle to the miner without being exposed. 

In the broad sense, the mentioned arbitrages improve the efficiency of the DeFi market by bridging the price information. On the other hand, [Sandwich MEV](https://eigenphi-1.gitbook.io/classroom/mev-types/sandwich-mev), also known as front-running, is terrible for the market and harms investors' interests.
