Welcome here,
I would build custom Mev Bot on Solana, Ethereum or Bsc Blockchain.
Why Offer Demo?
I offer demo cause lots of buyers complain of paying their dev and dev wont reply anymore or it having no profits at all.
so instead of been skeptical about my bot.
I indeed offer a simple frontrunning bot, that would require 3 to 4 parameters, and would work just for 7days before expiring.
with this you can be able to test and check the bot profitability before Ordering me or proceeding
NOTE: You would trade with your trading amount and my Mev Bot frontrun large trades.
