# Why Overlayer?

> Why Overlayer upgrades stablecoins instead of replacing them: a non-rebasing settlement asset kept separate from an opt-in, share-based yield layer.

Most stablecoins are excellent settlement assets, but they are not designed to be natively productive on-chain for users. Overlayer does not try to replace stablecoins; it upgrades them.

Instead of embedding yield directly into the transferable asset, Overlayer separates the system into two layers:

1. **Non-rebasing overlaid asset** for settlement and composability.
2. **Staked representation** for yield participation.

This matters for three reasons:

* **Settlement stays clean.** The base overlaid asset does not rebase and behaves like a normal transferable token.
* **Yield stays explicit.** Users opt into yield by staking, meaning yield is not hidden inside every wallet balance.
* **Risk boundaries are easier to reason about.** The protocol isolates optional modules and external integrations from core accounting and redemption invariants.
