Variational's Omni opens its public mainnet, with protocol open interest exceeding $1.5 billion.

November 11: Arbitrum on-chain derivatives protocol Variational announced that the private beta of its trading platform Omni has concluded, and the public mainnet is now open, with registration no longer requiring an invite code. The Omni 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 official statement, after approximately 20 months of development, the protocol's open interest has exceeded $1.5 billion, with cumulative trading volume surpassing $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 the crypto market, and recently brought TradFi liquidity on-chain through swaps. Currently, all users are supported in trading over 550 listed traditional assets and crypto instruments on Omni.
