About the company
We founded Ostium with a simple mission: Anyone with a digital wallet should be able to trade stocks, commodities, currencies, and crypto in one place, with full transparency. This started in a hacker house, running arbitrage on offshore CFD brokers - until they froze our accounts and withheld our deposits. We learned the hard truth: their terms meant nothing. The Market We're Going After. CFDs are the world’s largest retail derivatives market - over $10T monthly volume across every major asset class - but they're built on black-box execution, custodial discretion, and antiquated tech. We’re turning that system on its head. Ostium is building a decentralized perpetuals protocol for real-world markets, with onchain transparency replacing blind trust. Spreads, liquidations, and collateral are visible to everyone. No brokers. No freezes. No hidden spreads.
