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. The code works fine in remix and sends no dployment version error. 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. Solidity is a statically typed, contract-oriented, high-level language for implementing smart contracts on the Ethereum platform. But when I right click and select Solidty:Compiler information, it shows 0.8.0. from output: Retrieving compiler information: Compiler using remote version: 'v0.8.0+commit.c7dfd78e', solidity version: .8.0+commit.c7dfd78e.Emscripten.clang Not sure if that is related to the issue I face.
