Contract interface naming conventions
There has 2 been 2 much 2 debate about the current convention for external function naming. Much of that debate has happened earlier in the ecosystem’s development to a smaller audience, so, at the risk of beating a dead horse, I wanted to open the discussion more broadly here.
Starknet and Cairo have made it an explicit non-goal to provide evm compatibility, opting instead to design a platform around the unique constraints of zkstarks. An existing convention has formed to maintain a façade of compatibility through contract interface function naming. In the following, I’ll make a case that this convention doesn’t accomplish its goals, as well as propose some potential paths forward.
Through the EIP process, the Ethereum ecosystem, on top of which the Starknet blockchain operates, has standardized interfaces (ERC20, ERC721, ect) based on Solidity implementations. Solidity uses camelCase naming by convention. Cairo uses camel_case. As such, we’ve landed in the awkward spot where Solidity conventions are leaking into Cairo implementation, in an attempt to make interfaces compatible.
While the goal of compatibility is a reasonable one, function naming is just a human readable representation of a contracts interface. Ultimately, the compiled artifact is the interface for compatibility and Solidity and Cairo differ significantly in how function names are mapped to entry point selectors by the compiler.
Solidity supports argument dependent lookups, hashes function names with keccak, and uses the first four bytes as the selector:
keccak("helloWorld(uint256 foo)")[:4]Cairo does not support argument dependent lookups, hashes function names with keccak, and uses the first 250bits as the selector:
keccak("helloWorld") & 2^250-1As a result, while function interface naming is the same, the lower level interpretation is different, and thus there isn’t a de facto “compatibility” as a result of sharing function naming conventions: any existing libraries would need to introduce some level of adaptation to support Starknet.
Nevertheless, it seems there is enough support for maintaining camelCase external interfaces.
