what we do?
Fat Solutions is a crypto dev shop that maxes out on zero-knowledge but doesn’t stop there. We’re focused on using new zk primitives to unlock fresh potential on the application layer — think private social logins, identity tools, wallets, or private token standards that actually change the game. We’re tapping into what zk can do to build things that deliver real value to users, not just hype.
mission?
We’re a team of engineers and researchers deep into zk tech, shaping it into apps that prioritize privacy and function, proving zero-knowledge can deliver in the real world. It’s still early for zk, and we’re here to build practical solutions that show its power now while setting the stage for what’s ahead.
