# Bitcoin Denomination & Contracts

> All Roxom contracts are quoted, settled, and margined in BTC, with each contract representing a fixed asset quantity.

<Tip>
  For a user-friendly guide to BTC denomination and supported currencies, see [Supported currencies](/help-center/account-basics/supported-currencies) in the Help Center.
</Tip>

### Quote currency

Prices are quoted in BTC terms (e.g., an asset price might be shown as 0.0025 BTC). For convenience, the UI may also display this as satoshis (e.g., 250,000 sats).

### Settlement currency

All profits, losses, and collateral are denominated and settled in BTC.

### Contract unit

Each contract represents a fixed quantity of the underlying asset (e.g., GOLD/BTC has its own contract size, measured in ounces of gold).
