what's Ostium?

Ostium is a decentralized perpetual futures trading protocol on Arbitrum, designed for Real World Assets (RWAs). Users trade leveraged perpetuals on stocks, commodities like gold (XAU), forex, indices, ETFs, and crypto with full self-custody from their wallets. It delivers tight spreads and low slippage by aggregating liquidity and pricing from the most liquid traditional markets via a proprietary quoting engine powered by Stork and Chainlink oracles. Liquidity providers deposit USDC into Ostium Liquidity Provider (OLP) vaults to earn trading fees and liquidation rewards with reduced directional exposure. Positions settle instantly on-chain, feature predictable real-world funding rates, and support up to 200x leverage. Trading halts during TradFi closures for risk management, ensuring reliable execution otherwise.

Ostium's open interest is 87% traditional assets.
