Each weekday leading up to devcon2, Nexus will highlight a dapp, library, or package (something with a dappfile) as a promotion of our toolchain and as case studies for other developers. Previous Post

Today's dapp is the beginning of an isolated repo specifically for exploring quirks and edge cases of solidity and the EVM. Right now it has two case studies. The first explores solidity call semantics
