Cyclic arbitrage works by finding a route through a single DEX with the same input and output token. On Near Protocol this is generally done by finding a route with wNEAR as input and output token. There is an arbitrage opportunity, if the amount of output tokens is higher than the amount of input tokens + gas fees. Arbitrage bots are scanning all pools on Ref Finance to find such a potential route.
Arbitrage bots are developed by individuals and it's basically impossible to share revenue. If you see someone trying to let you invest into arbitrage trading, then it's 100% a scam.
