Cosmos developers bring IBC to Ethereum in landmark interoperability test

Cosmos developers are working to extend the Inter-Blockchain Communication (IBC) protocol to Ethereum.

According to Maghnus Mareneck, co-CEO of Interchain Labs, Cosmos developers have successfully tested IBC transactions between Cosmos Hub and Ethereum in an apparent effort to enhance native token interoperability.

The development is a component of the upcoming Eureka upgrade for IBC by teams, including Interchain Labs, and is planned for release as part of IBC-go v10 this year.

Cosmos developers aim to establish the IBC protocol as the global standard for blockchain communication

A standardized protocol, Inter-Blockchain Communication (IBC), allows separate blockchains to communicate with one another and exchange data and assets without any problems. Light clients and relayers are used to achieve this.

Notably, Cosmos developers have been attempting to integrate the IBC protocol into Ethereum, an essential part of the Cosmos ecosystem.

The inclusion of other major networks like Ethereum and Solana builds upon the developers’ vision of developing IBC into a universal standard for blockchain communication by expanding its reach beyond Cosmos.

Therefore, the first step would be linking Ethereum to the Cosmos’ central chain, Hub.

According to Cosmos developers, growing IBC could result in new opportunities for decentralized finance and cross-chain applications.

Other development initiatives are underway to incorporate IBC into Ethereum through specialized projects like Polymer, Picasso, and Union.

Cosmos positions itself as a coordinating layer amid optimistic investor sentiment

On March 13, 2025, the IBC Eureka Town Hall took place as prominent speakers discussed the future of Cosmos Hub and the Inter-Blockchain Communication (IBC) protocol.

The event aimed to draw investors hoping for growth because those subjects were set to provide crucial insights and advancements for Cosmos, which could raise the price of ATOM.

Moreover, new updates about Cosmos as a coordination layer may positively affect investor sentiment. 

However, the announcements’ final impact on price will rely on how well they meet or surpass expectations. Therefore, analysts advise investors to always look for important news.

EVM’s availability on several blockchains has led to its widespread adoption as a smart contract standard 

The Interchain Foundation helped make Evmos, a canonical EVM framework for Cosmos’ multi-chain ecosystem with more than 200 app chains, publicly available.

Originally created as part of the Evmos project, the foundation says that this framework will now be maintained as Cosmos EVM within the official Interchain software stack, which includes the Cosmos SDK.

The Cosmos ecosystem now offers a standardized version of Ethereum Virtual Machine (EVM).

To achieve full EVM compatibility, including support for JSON-RPC and Ethereum wallets, Cosmos blockchains can now integrate Cosmos EVM through a lightweight EVM configuration for native ERC-20 tokens.

Through the use of the Inter-Blockchain Communication protocol, the integration improves Cosmos’s compatibility with the wider EVM ecosystem across chains.

According to the project, co-founder Federico Kunze Küllmer will continue to advise the Interchain Foundation on the interoperability and modular architecture of Cosmos EVM. Still, he will no longer be a key contributor to Evmos.

Furthermore, Kunze Küllmer’s company, Altiplanic, the primary developer of the Evmos codebase, which earlier contributed to the project, will no longer do so.

Evmos, originally known as Ethermint, was first conceived in 2016 and launched as a Cosmos-based chain on the mainnet in 2022 to bring EVM to the Cosmos ecosystem. That same year, Polychain Capital led a token sale round in which its developers raised $27 million.

EVM has emerged as the most popular smart contract standard since the beginning of this decade and is currently present on several blockchains that seek to emulate Ethereum’s popularity.
