# Accessing Stratium

Stratium operates two trading interfaces on Hyperliquid mainnet.

### Perpetuals: [trade.stratium.xyz](http://trade.stratium.xyz)

Trade perpetual futures through Stratium's Builder Code.

Your existing Hyperliquid USDC balance works across all markets. Same orderbook, same matching engine, same margin system as native Hyperliquid perps.

### Binary Options: [markets.stratium.xyz](http://markets.stratium.xyz)

Trade binary options through HIP-4.

HIP-4 markets are fully collateralized outcome contracts denominated in USDC. Positions settle to 0 or 1 at expiry. Zero fees to open positions. No leverage. No liquidation.

The interface includes a real-time orderbook, price charts, position and P\&L tracking, and a leaderboard.
