I'm currently working on making the economy programable with Evan Conrad. We've been working on everything from a decentralized Steam competitor, to ordering pizza with crypto.
You can follow along on my Twitter if that sounds interesting.

This JPG is actually worth something

The above JPG is worth $100 USD at the time of writing. It's not an NFT with speculative value. It is $100. Well, until someone withdraws it.
But first, how does it work?
One cool thing about crypto is that it's more like cash than a credit card. It's a bearer asset, which means you don't need a third party to prove you have the thing.
If I hand you a dollar bill, you are now the owner of a dollar bill. I didn't need anyone else to prove that I had a dollar or was able to hand it to you.
Credit cards don't work like this at all, but crypto does. Having the private key to a wallet is having all its assets. You can prove you have them and send them to anyone using the blockchain.
Inside that QR Code's data is a private key. That private key controls a wallet on Ethereum that holds 100 USDC. Holding the wallet means you hold the $100.
Also, there's a nice UI for making, funding, and cashing out these QR Wallets.
Why are QR Wallets cool?
You can create super cheap and easy to use hardware wallets. It's at least 100x cheaper than a Ledger Nano X and 100x more usable than a seed phrase on paper.
You can do all sorts of things with that:
90% of the functionality of a checking account is in that QR code. There's something very satisfying to me about that.
