Variational’s Omni Opens Public Mainnet: Protocol Open Interest Exceeds $1.5 Billion

Variational—a derivatives protocol on Arbitrum—has officially announced that its trading platform, Omni, has concluded its private beta phase and is now fully open to the public on mainnet, with no invite code required for user registration. The private beta began in January 2025 and was initially limited to whitelisted addresses connected to the testnet and those on the Discord waitlist. According to official disclosures, after approximately 20 months of development, the protocol’s total open interest has surpassed $1.5 billion, and its cumulative trading volume has exceeded $450 billion. During the private beta, Variational established a zero-fee policy as a long-term mechanism and simultaneously launched a referral program and points system; the platform completed two major UI overhauls; it became the first crypto-native platform to integrate TradFi markets beyond the crypto space; and most recently, successfully bridged TradFi liquidity onchain via token swaps. Omni now supports all markets.
