Solidity is a statically-typed curly-braces programming language designed for developing smart contracts that run on Ethereum. Compiling for the wrong EVM version can result in wrong, strange and failing In addition, it also specifies the support of the smart contract for Solidity versions above the specified version. // - `*`: Wildcard value that can be used to request everything. Because a Solidity file can include multiple contracts and because contracts can import other contracts, multiple contracts are often compiled. will select every. // code of the called function is available at compile-time.
