Arbitrage

i am looking for arbitrage opportunity, buy USDT cheap sell for FIAT high. the currency [ nigerian nira] is quite unstable there is the official bank rate, blackmarket rate and rate on p2p platforms. i saw an opportunity on kyberswap last year when the spread was decent and the fees would also be covered with that spread, but they adjusted the rate and i have been looking for DEX's that i can replicate such opportunity. any suggestion or aggregators i can watch and compare. THANK YOU

ngn arbitrage on dexes is a tough game, most spreads get sniped by bots super fast, so you're better off watching aggregators like 1inch or etc on less liquid l2s for fleeting opportunities, but really pay attention to gas fees and slippage, they'll eat your lunch
