Key Takeaways
Omni Network was a cross-rollup interoperability protocol built on Ethereum that allowed decentralized apps and users to interact across multiple Layer 2 rollups.
The network used EigenLayer restaking for economic security, where validators restaked ETH or liquid staking tokens to secure cross-rollup messaging.
In December 2024, Omni launched its Core mainnet, introducing the Omni Orderflow Engine and SolverNet to help unify the fragmented Ethereum rollup ecosystem.
In September 2025, Omni Network rebranded to Nomina (NOM) with a 1:75 token swap. The project pivoted from cross-rollup developer infrastructure to a unified trading terminal for perpetual futures DEXs. Omni Core was sunset, and assets migrated to Ethereum in February 2026.
The OMNI token is now defunct. The NOM token serves as the native asset for the Nomina ecosystem.
Introduction
The Ethereum rollup ecosystem has grown rapidly, with dozens of Layer 2 networks processing transactions at lower costs than the Ethereum mainnet. While this scaling approach has expanded capacity, it has also fragmented liquidity and user experience across separate networks. Omni Network was a blockchain protocol designed to address this by providing a cross-rollup communication layer.
This article explains what Omni Network was, how it worked, the milestones it reached, and the September 2025 rebrand to Nomina that transformed the project.
What Was the Omni Network?
Omni was a protocol built on top of Ethereum that enabled cross-chain interoperability between different Ethereum Layer 2 rollups. Rather than operating as a standalone competing network, Omni functioned as a coordination layer, allowing smart contracts and assets on separate rollups to interact with each other.
The protocol was secured by EigenLayer restaking. This means validators secured the Omni network by restaking assets they had already staked on Ethereum, allowing Omni to inherit Ethereum's economic security without requiring validators to set aside entirely separate capital.
The OMNI token was the native asset of the network. It was used to pay for cross-rollup transaction fees, participate in on-chain governance, and delegate to validators. Omni was included as the 52nd project on the Binance Launchpool in April 2024, where users could stake BNB and FDUSD to earn OMNI tokens.
How Did Omni Network Work?
EigenLayer security
Omni operated as an Actively Validated Service (AVS) on EigenLayer. Validators registered with OmniAVS, a smart contract deployed on Ethereum that managed their participation. These validators restaked ETH or liquid staking tokens as collateral. If validators acted dishonestly, their staked assets could be slashed as a penalty. This approach let Omni benefit from Ethereum's economic security model. Following the September 2025 rebrand and the sunset of Omni Core, this AVS architecture is no longer the primary operating model for the Nomina ecosystem.
Cross-rollup messaging
At the protocol's core was a cross-rollup messaging system. When an application on one rollup wanted to trigger an action on another, it submitted a message to Omni Core. Validators attested to the message, and it was relayed to the destination rollup. This mechanism allowed decentralized applications to span multiple networks without relying on traditional bridges.
The Omni Orderflow Engine and SolverNet
Launched with the Core mainnet in December 2024, the Orderflow Engine was Omni's higher-level system for cross-rollup user interactions. SolverNet was one component: a network of solvers that competed to fulfill cross-rollup user intents. For example, a user who wanted to swap a token on one rollup using liquidity from another could do so through SolverNet without manually bridging assets first.
Following the rebrand to Nomina, the SolverNet SDK remains available for teams that relied on it, though the primary product focus has shifted to the trading terminal.
Key Milestones
Omni Armageddon mainnet (April 2024)
In April 2024, Omni launched its first mainnet phase, known as Omni Armageddon. This phase focused on enabling restaking through EigenLayer, allowing users to stake ETH and liquid staking tokens to contribute to network security. The OMNI token was also launched during this period.
Omni Core mainnet (December 2024)
In December 2024, Omni launched Omni Core, its full cross-rollup communication protocol. This was considered the first complete version of the network's core infrastructure. It targeted the more than $58 billion in total value locked (TVL) spread across over 40 Ethereum rollups at the time.
Magellan upgrade (February 2025)
In February 2025, Omni released version 0.13.0, the Magellan network upgrade. This introduced permissionless OMNI delegation, allowing token holders to delegate their OMNI to validators without restrictions. It also included consensus improvements to the network's finalization process.
Rebrand to Nomina (September 2025)
In September 2025, Omni Network rebranded to Nomina. The rebrand included a 1:75 token swap, where 1 OMNI was converted to 75 NOM. Binance completed the token swap and removed all OMNI spot pairs by October 1, 2025. The OMNI token is now defunct.
The rebrand also marked a strategic pivot. Rather than continuing as a cross-rollup developer infrastructure protocol, Nomina positioned itself as a unified trading terminal for perpetual futures DEXs. The first prototype of the trading terminal was released in August 2025 for selected testers. Nomina has since integrated with multiple perp DEXs, including Gearbox, Cygnus Finance, and Extended, enabling cross-chain lending and trading without leaving the user's application.
Omni Core sunset and Ethereum migration (February 2026)
In February 2026, Omni Core was officially sunset, and all assets migrated to Ethereum. The SolverNet SDK remains available for teams that built on the original infrastructure, but the Nomina ecosystem now operates primarily as an Ethereum-native trading protocol. The NOM token serves as the native asset for the network.
FAQ
What was Omni Network used for?
Omni Network was used to connect separate Ethereum Layer 2 rollups, allowing decentralized applications, tokens, and user actions to move between rollups without manual bridging. Its Orderflow Engine and SolverNet were designed to make this process seamless for users. Following the September 2025 rebrand to Nomina, the project pivoted to a trading terminal model for perpetual futures DEXs.
How did Omni Network achieve security?
Omni used EigenLayer's restaking infrastructure. Validators staked ETH or liquid staking tokens as collateral. If they behaved dishonestly, their staked assets could be slashed. This meant Omni could achieve Ethereum-level economic security without building a fully independent validator set. Following the rebrand and Omni Core sunset, this architecture is no longer the primary operating model.
What happened to the OMNI token?
The OMNI token was swapped to NOM (Nomina) at a 1:75 ratio in September 2025. Binance completed the swap and removed all OMNI spot pairs by October 1, 2025. The OMNI token is now defunct. NOM serves as the native token for the Nomina ecosystem.
What is the Omni Orderflow Engine?
The Orderflow Engine was Omni's product layer that allowed users to perform cross-rollup actions with a single transaction. SolverNet, one part of the engine, routed user intents across rollups by having competing solvers fulfill actions. Following the rebrand, the SolverNet SDK remains available, though Nomina's primary focus is now the trading terminal.
What is Nomina?
Nomina is the rebranded version of Omni Network, launched in September 2025. It operates as a unified trading terminal for perpetual futures DEXs, integrating with multiple protocols including Gearbox, Cygnus Finance, and Extended. The NOM token is the native asset, swapped from OMNI at a 1:75 ratio. Omni Core was sunset in February 2026, and the ecosystem now operates primarily as an Ethereum-native trading protocol.
When did Omni Network launch?
Omni launched its first mainnet phase, Omni Armageddon, in April 2024. Its Core mainnet followed in December 2024. The Magellan consensus upgrade was released in February 2025. The project rebranded to Nomina in September 2025, and Omni Core was sunset in February 2026.
Closing Thoughts
Omni Network took a specific approach to addressing Ethereum's rollup fragmentation problem. By building a cross-rollup communication layer secured by EigenLayer restaking, it aimed to make decentralized applications and user interactions work seamlessly across multiple networks. The project reached several milestones, including its Core mainnet and Magellan upgrade.
However, the September 2025 rebrand to Nomina marked a significant pivot. The project shifted from cross-rollup developer infrastructure to a trading terminal for perpetual futures DEXs, and the OMNI token was replaced by NOM. As with any protocol that undergoes a major transformation, users should research the current state of the project independently before engaging with any related assets or applications.
