Select yes if you want to show nightly builds.
The compiler version is specified in pragma solidity X.X.X. Use the compiler version rather than the nightly build. If using the Solidity compiler, run solc —version to check.
The EVM version the contract is written for. If the bytecode does not match the version, we try to verify using the latest EVM version. EVM version details.
If you enabled optimization during compilation, select yes.
We recommend using flattened code. This is necessary if your code utilizes a library or inherits dependencies. Use the POA solidity flattener or the truffle flattener.
Add arguments in ABI hex encoded form. Constructor arguments are written right to left, and will be found at the end of the input created bytecode. They may also be parsed here.
