Ostium is positioning the new system as a transparent, self custodial alternative to the CFD market, which it estimates at about $10 trillion in monthly volume.
Under the new architecture, a separate capital pool programmatically hedges net exposure offchain through institutional partners, while settling once daily against a buffer layer that sits above the public liquidity pool.
The liquidity pool now functions as an intraday lending layer, allowing the protocol to scale open interest more closely with liquidity in the underlying markets.
The company said the system uses a translation layer between smart contracts and institutional messaging protocols, with sub 100 millisecond latency across each step.
Ostium CTO Marco Antonio Ribeiro said the infrastructure was built over four months by 15 of the company’s 20 engineers, describing it as the first time onchain flow has been programmatically hedged through traditional market participants.
The launch expands Ostium’s push to offer wallet based exposure to stocks, commodities, indices, ETFs, and FX without requiring users to give up custody of their funds.
Ostium’s own site describes these products as synthetic perpetual exposure, meaning traders gain price exposure to assets such as the S&P 500 or gold without owning or redeeming the underlying asset.
The upgrade follows Ostium’s $20 million Series A in December, co-led by General Catalyst and Jump Crypto, after the company said it had already reached about $25 billion in cumulative volume and that more than 95% of open interest was tied to traditional markets.
Ostium CEO Kaledora Kiernan Linn framed the launch as a broader attempt to do for global markets what stablecoins did for the dollar, making a widely demanded financial product more accessible, programmable, and transparent. The upgrade is now live, with trading available through Ostium’s app.
