Breaking: Variational’s Omni opens public mainnet; protocol open interest exceeds $1.5 billion

BlockBeats news, November 11: Arbitrum-based derivatives protocol Variational announced that private testing of its trading platform Omni has ended, and its public mainnet is now open. Registration no longer requires an invitation code. Omni’s private test began in January 2025, initially opening to a small number of whitelisted addresses from its testnet and Discord waitlist. The team says that after about 20 months of development, the protocol’s open interest has exceeded $1.5 billion, with cumulative trading volume surpassing $450 billion. During private testing, Variational made zero fees a long-term policy, launched referral and points programs, redesigned the interface twice, and introduced its first TradFi markets beyond crypto. More recently, it brought TradFi liquidity on-chain through swaps. Omni now supports all users trading more than 550 listed traditional assets and crypto markets.
