# Supported currencies and what they're used for

> Learn which currencies Roxom supports, what networks are available, and how each currency is used across the platform.

## How each currency works on Roxom

### BTC (Bitcoin)

BTC is the **core currency** of Roxom. Everything on the platform is BTC-denominated:

* **Deposits and withdrawals**: Via the Bitcoin native network
* **Trading**: All futures positions and One-Click Trade swaps are quoted, margined, and settled in BTC
* **P\&L**: Your profit and loss is always in BTC
* **Fees**: Trading fees are charged in BTC
* **Auto-Earn**: BTC held in your Funding Account can generate earnings

<Info>
  BTC, USDC, and USDT can all be transferred to your [Unified Trading Account (UTA)](/help-center/account-basics/understanding-your-roxom-accounts). However, only BTC can be used for trading, USDC and USDT must be sold for BTC first.
</Info>

### USDC and USDT (Stablecoins)

USDC and USDT can be deposited, withdrawn, and transferred to the UTA, but they **cannot be used directly for trading**.

* **Deposits**: Via Polygon, Base, or Ethereum networks
* **Withdrawals**: To external wallets on the same networks
* **Transfer to UTA**: You can move USDC and USDT to your Unified Trading Account
* **Sell for BTC**: Once in the UTA, you can sell USDC or USDT for BTC using [One-Click Trade (Swap)](/help-center/one-click-trade/what-is-one-click-trade-what-assets-are-available)
* **Cannot buy or trade directly**: You cannot use USDC or USDT to open positions or buy assets, all trading is BTC-only
* **No Auto-Earn**: Only BTC qualifies for Auto-Earn rewards

<Note>
  If you deposit USDC or USDT and want to trade, transfer them to your UTA and sell them for BTC using One-Click Trade (Swap). You can then use that BTC to trade.
</Note>

## Why everything is BTC-denominated

Roxom is built around Bitcoin as the unit of account. This means:

* **Contract prices** are quoted in BTC (e.g., GOLD/BTC shows the price of gold in Bitcoin)
* **Margin and collateral** are posted in BTC
* **Profit and loss** is calculated and settled in BTC
* **Trading fees** are charged in BTC

This lets you track your performance directly in Bitcoin terms, without needing to convert to fiat.

<Info>
  For the full technical details on BTC denomination, see [Bitcoin Denomination & Contracts](/rulebook/key-contract-specs-shared/bitcoin-denomination-and-contracts) in the Rulebook.
