Open Interest Exceeds $1.5 Billion, Variational's Omni Opens Public Mainnet

Odaily reports that Variational, a derivatives protocol on Arbitrum, has announced that its trading platform Omni is ending its private beta and opening its public mainnet starting today, with no invitation code required for registration. Omni's private beta launched in January 2025, initially opening only to a small number of whitelisted addresses from the testnet and Discord waitlist. According to the team, after roughly 20 months of development, Omni's open interest has surpassed $1.5 billion, with cumulative trading volume exceeding $450 billion. During the private beta, Variational established zero fees as a long-term arrangement and launched a referral program and points program, redesigned its interface twice, introduced its first TradFi markets outside of crypto, and recently brought TradFi liquidity on-chain through swaps. Currently, all users can trade more than 550 listed traditional assets and crypto instruments on Omni.
