Nomina launches interop layer

Nomina has launched a network meant to make trading across Ethereum rollups feel like one market instead of several separate chains. (nomina.io) To follow the launch, it helps to start with the problem: Ethereum scaling now happens on many Layer 2 networks, and users often have to bridge assets, switch networks, and hold different gas tokens just to move between them. Nomina’s own documentation says that fragmentation splits users and capital across chains and forces people to manage bridging and gas on each destination network. (docs.omni.network) Nomina says its network is built for “sub-second cross-rollup verification,” which means it is trying to confirm messages between rollups in under a second rather than making users wait through slower bridge flows. The company says that design is based on CometBFT, a consensus engine used to order and finalize transactions quickly. (nomina.io, nomina.io) The launch also includes what Nomina calls a Universal Gas Marketplace. In its whitepaper post, the company says users will be able to pay gas on a destination rollup with the native asset of the chain they start from, or with the NOM token directly. (nomina.io) The project did not start as Nomina. It operated as Omni, announced its rebrand on August 12, 2025, and said the network upgrade on September 23, 2025 automatically migrated OMNI held on the Omni EVM to NOM; the published swap ratio was 1 OMNI to 75 NOM. (nomina.io) That rebrand kept the same basic pitch: one interoperability layer connecting Ethereum rollups. Nomina’s whitepaper says the underlying protocol remained the same after the name change, while the older Omni docs still describe the product as a “chain abstraction layer” that lets developers deploy once and reach users across supported chains. (nomina.io, docs.omni.network) The first networks in focus are the biggest Ethereum rollups. Nomina and Omni materials say support starts with Arbitrum, Base, and Optimism, and an Omega testnet update said those three rollups were connected alongside Ethereum Layer 1 for cross-network communication. (nomina.io, nomina.io) Those chains are where much of Ethereum’s off-mainnet activity already sits. L2BEAT’s data page, crawled April 11, 2026, showed about $15.75 billion in total value secured on Arbitrum One, $11.44 billion on Base, and $1.49 billion on OP Mainnet. (l2beat.com) Nomina is also still tying its security story to Ethereum restaking. Omni said in March 2024 that Ether.Fi committed $600 million in staked Ether to help secure the network through EigenLayer, and Nomina’s current whitepaper says the network derives its cryptoeconomic security from Ethereum Layer 1 and plans to reinforce that model as the ecosystem grows. (cointelegraph.com, nomina.io) The open question is whether traders and developers will trust one more coordination layer in an already crowded market for bridges, intents systems, and rollup tooling. Nomina’s bet is that if cross-rollup trades really settle in under a second and gas handling disappears into the background, users will notice the speed and not the plumbing.
