About
The problem it solves If you don't like soccer like us, but you like cryptos, use FantaCrypto instead!
How it's made
Challenges we ran into - testing API3 oracle locally with Foundry (we forked Polygon zkEVM chain) - frontend was too difficult to integrate all stuff in less than 2 days (errors with wagmi readContract feature, validating inputs, testing it)
