Cosmos devs test IBC protocol between Hub and Ethereum to boost interoperability

Quick Take

  • Cosmos developers are working to extend the Inter-Blockchain Communication (IBC) protocol to Ethereum.
  • Interchain Labs tested an IBC transaction from Cosmos Hub to Ethereum, showing progress in native interoperability between the two chains.

Cosmos developers have been working to extend the Inter-Blockchain Communication (IBC) protocol, a cornerstone of the Cosmos ecosystem, to Ethereum.

On Wednesday, Maghnus Mareneck, co-CEO of Cosmos core contributor Interchain Labs, said the firm tested an IBC transaction from Cosmos Hub to Ethereum in what appears to be an effort to boost native interoperability of tokens between these two networks.

The move is part 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.

This upgrade builds on the developers' vision of making IBC a universal standard for blockchain communication, extending its reach beyond Cosmos to major networks like Ethereum and Solana. The first step would be connecting Ethereum to the Cosmos' central chain, Hub.

IBC is a standardized protocol that enables communication between independent blockchains, allowing them to transfer assets and data seamlessly. It does so using light clients and relayers.

According to Cosmos developers, expanding IBC could potentially open new opportunities in decentralized finance and cross-chain applications.

There are other development efforts to bring IBC to Ethereum through specific projects such as Picasso, Union, and Polymer.
