Onchain perpetuals exchange Ostium said Monday it has partnered with U.S. stock exchange operator Nasdaq.

The tie-up makes Ostium, the "first onchain trading venue to offer equity perpetual products powered by Nasdaq data," the firm said in a post to social media.

"Access to U.S. markets has historically been fragmented, permissioned, broker-gated, and limited by geography," Ostium also said. "Traders worldwide can now gain exposure to U.S. equities on Ostium with the benefits of blockchain rails: transparency, instant-settlement, and self custody."

Ostium is a decentralized perpetuals trading platform that became one of the first to offer leveraged trading in traditional assets, such as stocks, indices, commodities, ETFs, forex, and other assets. The platform has processed over $50 billion in cumulative volume and across more than 26,000 traders, the company said last month.

Ostium serves as a kind of TradFi-DeFi bridge, where users can remain fully self-custodial while benefiting from institutional-grade liquidity, pricing, and depth from offchain venues.
