# Mint & Redemption

### Overview

A credible on-chain real asset requires more than issuance. It must maintain a clear and enforceable path between the on-chain token and its underlying reserve.

Within Ontorium, minting and redemption are designed as core mechanisms of the Asset Layer. They preserve a direct link between the on-chain token and its underlying asset, and ensure that OXAU issuance remains disciplined and grounded in its real-world reserve model.
