On January 21, Noble announced that the team will officially launch an all-new EVM Layer 1 mainnet on March 18, 2026. This new network, built on the Commonware architecture, will no longer rely on the existing Cosmos SDK chain—marking a pivotal shift in Noble’s core technology strategy.

The new mainnet signals Noble’s transition from a Cosmos ecosystem application chain to a public chain architecture with an independent execution layer and greater scalability.

Core Features of the Next-Generation Layer 1

Noble’s new EVM Layer 1 mainnet is designed for high efficiency and financial-grade applications, with several key features highlighted by the team:

​​

• Sub-second transaction finality: Boosts real-time trading and settlement efficiency
• Open smart contract deployment: Full support for EVM ecosystem developers
• Dedicated payment channel mechanism: Delivers lower latency for payment and settlement scenarios

These features are tailored for high-frequency financial trading and stablecoin settlement—rather than functioning as a generic public chain.

USDN: The Core Asset of the New Network

Within the new mainnet framework, the native yield-bearing stablecoin USDN will serve as the ecosystem’s central asset. Noble plans to build out diverse financial use cases around USDN, including:

• Foreign exchange (FX) transactions
• Decentralized yield strategies (DeFi yield)
• Payment and settlement infrastructure

This approach shows Noble’s intent to position its stablecoin not just as a payment tool, but as a yield-generating, composable financial building block.

Plans for the Legacy Cosmos Chain

With the new EVM Layer 1 coming online, Noble’s current Cosmos SDK-based chain will gradually enter maintenance mode. The team has stated:

• IBC connections will remain active, ensuring uninterrupted cross-chain interoperability
• A comprehensive asset migration plan will be provided
• Existing users and partners can transition smoothly to the new architecture as planned

This plan aims to minimize ecosystem transition costs while preserving Noble’s established advantages within the IBC network.

Noble’s Original Role and Positioning

Before this transformation, Noble served as the stablecoin issuance infrastructure chain in the Cosmos and IBC ecosystem, focusing on helping issuers manage native assets—including minting, burning, and blacklist functions. Noble also acted as a distribution hub, enabling issuers to efficiently deploy assets across more than 50 blockchains and providing developers with easy-to-integrate application interfaces.

Summary

Noble’s launch of its new EVM Layer 1 mainnet is not just a technical upgrade—it’s a strategic repositioning. By making USDN the core asset, integrating rapid transaction finality, payment-focused architecture, and targeting DeFi, FX, and settlement applications, Noble is evolving from a stablecoin distribution hub to on-chain infrastructure for financial-grade applications. With continued IBC interoperability and a seamless migration path, whether this new chain can successfully integrate with the EVM ecosystem and drive real-world adoption will be a key market focus going forward.
