Lower values will optimize more for initial deployment cost, higher values will optimize more for high-frequency usage. All solidity source code should start with a "version pragma" which is a declaration of the version of the solidity compiler this code should use. Refresh the page, check Medium 's site status, or find something. What could go wrong if I change the version pragma of a third-party contract to make it importable with a newer Solidity compiler?

Making statements based on opinion; back them up with references or personal experience. 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.. // When using `false` they are replaced by multiplication with slack, // Using `true` here is recommended if you are using the CHC engine.
