[Variational's Omni Launches Public Mainnet; Protocol Open Interest Exceeds $1.5 Billion] BlockBeats reported on November 11th that Variational, the Arbitrum on-chain derivatives protocol, announced the completion of its private beta test for its Omni trading platform and the immediate launch of its public mainnet. Registration no longer requires an invitation code. The Omni private beta test began in January 2025, initially open only to a limited number of whitelisted addresses from the testnet and Discord waitlist. The official statement claims that after approximately 20 months of development, the protocol's open interest has exceeded $1.5 billion, with a cumulative trading volume exceeding $450 billion. During the private beta test, Variational made zero fees a long-term commitment, launched a referral program and a points program, redesigned its interface twice, launched its first TradFi marketplace outside the crypto market, and recently brought TradFi liquidity onto the blockchain through exchanges. Currently, Omni supports all users trading over 550 listed traditional assets and cryptocurrencies. [Original Link]
