I have been seeing that it is MEV. But in my case I don’t think it’s a determining factor. Since by the looks of it the MEV is how they order the transactions in the block to resolve them.
They do this in order to make a profit, talk about trades with the price of ETH, buy cheaper and sell more expensive positioning the transaction behind (the one that buys). In my case, it is a buy and sell of one nft.
If I compare the trades, I use the same gas limit and the same gas price. For a miner, this is not something usable since both transactions should be the same. Neither buys or sells the token. So I don’t know if MEV is really something to value here.
Anyway thanks for the info, it never hurts to learn new things.
