When you compile your contract code you can specify the Ethereum virtual machine According to the the Solidity Docs, the optimizer tries to simplify complicated expressions, which reduces both code size and execution cost, i.e., it can reduce gas needed for contract deployment as well as for external calls made to the contract.. src contracts Migrations.sol . 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. Typically, developers write the smart contract code in files with the ".sol" suffix and use the Solidity compiler to translate the source code into bytecode. Apart from exceptional cases, only the latest version receives most security fixes. Last time I tried verifying the contract on the ethereum tip jar (which I deployed myself) I was only able to get to 97% similarity. 1).
