# Backing Tokens

> Which assets can back a token's floor on RISE.

## Supported Backing Assets

When launching a token on RISE, creators choose the underlying asset that backs the floor:

* **SOL**
* **USDC**

<Warning>
  Each token market can only ever have one backing token, and this cannot be changed after creation. Choose carefully before launching.
</Warning>

## Why This Matters

The floor price is always denominated in the backing asset. This removes USD conversion risk from the floor guarantee:

* If you launch a SOL-backed token, the floor is quoted in SOL — 1 SOL will always be 1 SOL
* If you launch a USDC-backed token, the floor is quoted in USDC

This means holders always receive exactly the floor price in the base asset they understood at launch, regardless of the broader market conditions of the backing token itself.
