This section groups knowledge pages that are outside the manual playbooks and blockchain references.
We start here with fee documentation, split into onchain fees and prepaid fees so each model is clear and easy to compare.
This section is for platform mechanics that matter to merchants, developers, reviewers, and counterparties but do not fit neatly into a single manual flow or single blockchain page.
