I used some cool tools you may know – like Solidity+Foundry for the smart contracts and Next.js/Rainbowkit/Wagmi/Viem for the web app part.

The demo revolves around this neat little chat app where you can send messages without worrying about all the complicated crypto stuff such as gas fees etc.

If you've had a hard time with how clunky crypto usually feels for regular people, or if you're into building cool apps, that might help.
