Futureswap is a decentralized, non-custodial protocol for leveraged perpetual trading, letting users take long or short positions on crypto assets with leverage while liquidity providers earn fees and token incentives. Built by a small San Francisco team led by founder Derek Alia, it launched on Ethereum in 2020, later moved to Arbitrum and Avalanche for lower-cost transactions, and pioneered an AMM-based design that plugs into pools like Uniswap and Trader Joe. Backed by roughly $13.5M from investors including Ribbit Capital, Framework Ventures, True Ventures and Placeholder, it was governed by the community via its FST token.
Ostium is an onchain perpetuals exchange built on Arbitrum that lets anyone long or short real-world assets - stocks, commodities, indices, forex and crypto - directly from a self-custodial wallet, with up to 200x leverage and no broker in the middle. Founded by Harvard classmates and former Bridgewater hands Kaledora Kiernan-Linn and Marco Antonio Ribeiro, Ostium uses synthetic perpetuals and a custom oracle system to bring traditional markets onchain. It has processed tens of billions in cumulative trading volume and raised $27.8M total, including a $20M Series A co-led by General Catalyst and Jump Crypto in December 2025.
