Hello, Cairo!

1st production-grade Turing-complete STARK framework.
Already on Mainnet: @reddit demo.
Powering all upcoming systems: @deversifi, @Immutable, @dydxprotocol.
Need low gas for general computation at massive scale? There's Cairo for that https://t.co/VJams09cXe
Looking behind Starks we find Starkex, which is powering https://www.deversifi.com/#token and this is trading the $NEC token
Which given all the talk about Gas fees, it looks like these Stark transaction methods might help reduce the fees on Defi exchanges?
