Stampedr

I Built Stampedr to kill the "I never got that" fight freelancers keep having with clients — it fingerprints whatever you deliver and locks a timestamp for it on Monad, permanently, so you send a link instead of arguing. Along the way I learned Monad bills gas by limit not actual usage (so you really don't want to skip simulating before you send), that a custodial wallet setup means one leaked key can sink every user at once if you're not careful about rotation and spend limits, and honestly how far good UX can go toward hiding crypto complexity entirely — signup just quietly spins up and funds a real wallet, no one has to think about it.
