The compiler can produce various outputs, ranging from simple binaries and assembly over an abstract syntax tree (parse tree) to estimations of gas usage. // Use the given hash method for the metadata hash that is appended to the bytecode. How to develop and compile with hardhat using imports with different pragma/compiler versions? // URL(s) result in success, an error should be raised. In a similar to way to ERCs and as we work towards to more interoperable smart contracts, being able to quickly examine those interfaces that you want to integrate is a time saver. chore: change all makefile targets into phony targets.
