Using the publish button, you can upload your contract to IPFS or Swarm (only non abstract contracts can be published to Swarm). The staticcall opcode is used when calling non-library view or pure functions, which prevents the functions from modifying state at the EVM level, i.e., even applies when you use invalid type conversions. Comments are of course not permitted and used here only for explanatory purposes. It is important to address reported issues even if the compiler doesnt complain. // "The Optimizer > Selecting Optimizations". When you publish your metadata to IPFS and deploy your code to the mainnet or a public testnet, the contract verification service Sourcify, will verifiy your contracts without you needing to do anything. // If the option is omitted, "ipfs" is used by default.
