# Overview

**marginfi gives traders a single interface to trade across defi.** The protocol unifies liquidity to a single margin account, enabling traders to compose atomic positions across underlying trading protocols (UTPs).

Traders can finally run strategies like cross-DEX perp funding rate arbitrage, or cross-DEX atomically hedged market making — fully on-chain, with unified liquidity, unlocked leverage, and a single trader interface to manage everything.

Rebalance your portfolio on the upside, remove single protocol liquidation risk on the downside, and compose a complex portfolio with products at the best prices across DeFi.
