Noble to Migrate From Cosmos SDK to EVM Layer-1, Mainnet Set for March 2026

• Noble is migrating from the Cosmos SDK to an EVM-compatible Layer 1 chain focused on stablecoin applications and plans to go live on March 18, 2026.
• The new EVM chain should support stablecoin apps, currency payment rails, and DeFi applications with sub-second finality.

Noble, a blockchain protocol initially developed on the Cosmos blockchain, has announced that it will discontinue its Cosmos SDK-based blockchain and develop an Ethereum Virtual Machine (EVM)-based Layer 1 blockchain, which will be deployed on the Mainnet on March 18, 2026.

The move is quite significant from a tech shift standpoint for Noble. Since its launch in 2023, the solution has enabled stablecoin liquidity and interoperability for over different blockchains using the IBC provided by the Cosmos ecosystem for asset transfer/transactions. 

As per the announcements, the EVM Layer 1 will be designed specifically to support the function of stablecoins, foreign exchange (FX), and payments, and will be more performant and accommodating of developers compared to the original chain. As revealed by the team at Noble, during the transition, the original chain would be kept in maintenance mode.

The migration of an EVM-compatible architecture is designed to be a response to the shortcomings of the former Cosmos infrastructure, specifically with regard to programmability and the development of the ecosystem. EVM-compatibility, which has become a standard procedure on most blockchain platforms, will facilitate the development of applications on the chain, thereby expanding the ecosystem.

The newly formed Noble EVM chain is envisioned to provide sub-second finality for transactions, enabling a quick user experience for transfer, swap, and other types of transactions that are essential for payment system functionality. The addition of efficient consensus layers, such as Commonware primitives, enables the protocol to achieve synchronization between the need for security and the requirements of stablecoin-friendly workloads.

This follows industry trends where projects that started as experiments in developer frameworks like Cosmos are now moving towards EVM compatibility to benefit from larger developer bases and tooling ecosystems. 

The migration of the Noble network from being developed in the Cosmos SDK to being an independent EVM Layer-1 blockchain is a major shift in the alignment of the network’s infrastructure to meet the growing demand in the market for a scalable and programmatic space for stable and financial dApps. With the planned mainnet launch set for March 2026, Noble’s EVM seeks to ensure constant interoperability with the established infrastructure within the Cosmos ecosystem.
