Decentralized derivatives trading protocol Variational has successfully completed a $50 million Series A funding round, spearheaded by Dragonfly Capital. The round also saw participation from Bain Capital Crypto, Coinbase Ventures, and others. Variational, headquartered in the Cayman Islands, offers on-chain derivatives trading for real-world assets like oil and commodities by aggregating liquidity from major crypto exchanges and traditional financial market makers. The protocol aims to rival traditional markets such as CME, operating on a zero-fee, broker-like model. Its retail application, Omni, and the OLP liquidity pool are currently invite-only, with plans to expand access and tradable assets. In related developments, PopDEX, a decentralized perpetual contracts platform, raised $30 million in a funding round led by Foresight Ventures. The funds will be used to enhance liquidity, trading depth, and product development. Meanwhile, TownSquare completed its Pre-A funding round, bringing its total funding to $16.25 million to advance yield products and cross-chain brokerage services.
