Arbitrum-based derivatives protocol Variational opened its Omni trading platform to the public on November 11, 2026, ending its private test and removing the invitation-code requirement, according to BlockBeats. Omni’s private test began in January 2025 with a small group of allowlisted addresses drawn from its testnet and Discord waitlist.
Variational said the protocol had surpassed $1.5 billion in open interest and $450 billion in cumulative trading volume after approximately 20 months of development. Open interest measures outstanding contracts, while cumulative volume measures trading activity over time. Neither figure establishes protocol revenue or value accruing to token holders.
During the private test, Variational made zero trading fees a long-term arrangement, introduced referral and points programs, revised Omni’s interface twice, and added its first traditional-finance markets. It also recently brought traditional-finance liquidity on-chain through swaps. At the time of the report, Omni supported trading in more than 550 listed traditional and crypto assets.
