Why this hub exists

identifier, address, account, and code format validation usually involves more than one step, so users often need conversion, preview, validation, or export tools together.
Keeping identifier, address, account, and code format validation in one place makes it easier to compare the right path for a real workflow instead of jumping between unrelated pages.
The included samples let users test realistic inputs before running the same workflow on their own files, values, or payloads.
