if you're a hacker/builder, what's your favorite arbitrage opportunity you've found/executed on?

building reel.farm and farcasterstudio.com

my first "real" coding project was a trading bot that automatically bought dogecoin when Elon tweeted about it and sold 10 mins later

I like baking /goodbread and building apps on web3 protocols. DevRel @ ENS Labs. gregskril.com

I was only testing it with a few hundred $ and this was a few weeks before he got pressed about market manipulation so stopped tweeting as much... 

% wise was good but tiny scale. I was going to try and sell the bot but didn't get it out in time. https://doge.gregskril.com/ 

Unfortunate timing but great experience

smart move, did you end up making decent profit?? what was the outcome?
