This is a showcase of how we can push the limits of x402. The app shows how to do dynamic pricing based on app logic and handles payments on 3 chains and 4 different tokens through the @thirdweb x402 facilitator. We built this in 3 days. Ridiculously easy.

x402 to buy $CHAT with $USDC on @arbitrum, @base or @0xPolygon at a fixed price x402 to post/reply spending $CHAT on @arbitrum In just a few lines of code, we created our own app economy.

One cool thing we realized while building this, is that x402 not only handles payment, it also has identity built in. Since payments are signature based, payer = user of our app. No need for any extra checks to ensure you own the wallet you're posting with!

The entire app is open source. Go check out the code, fork it, make it your own. There's so much more to explore with x402! github.com/thirdweb-dev/x402…

I airdropped 10 $CHAT to the first 350 ppl that replied to my last tweet. Go message your favorite people, so that they can post too, and be nice please! Had to be the first to post on @VitalikButerin page, let's see how expensive it gets 😄 x402.chat/0xd8dA6BF26964aF9D…
