“An open and interoperable bridge between Ethereum and Cosmos has long been a shared vision of a fully connected Interchain,” said Althea CEO Deborah Simpier.

On Wednesday, the Interchain Foundation, a Swiss non-profit serving as a steward of the Cosmos (ATOM) ecosystem, announced the launch of Gravity Bridge as built by decentralized internet service provider Althea. Gravity Bridge enables the transfer of ERC-20 tokens between the Ethereum (ETH) and Cosmos blockchains. During its initial stages, Gravity Bridge will operate as a standalone chain before migrating to Cosmos Hub early next year. Its key technical features include interchangeable token issuance across both chains and the support of Ethereum to Cosmos oracles.

Simpier issued the following statement regarding the launch:

In this interoperable ecosystem, Gravity Bridge’s place is a foundational piece of infrastructure, available to all Cosmos chains openly, purpose-built to update and iterate quickly, and facilitate the bridge needs of the chains that interact with it. Open markets and frictionless trading unlock liquidity for all. This is the future that uplifts all in the Cosmos network and supports the ATOM value and ecosystem for the Internet of Blockchains.

In March, the Inter-Blockchain Communication, or IBC, protocol launched on the Cosmos network, allowing for the communication and transfer of digital assets across different blockchains. There are now over 20 blockchains supporting IBC.

Billy Rennekamp, Cosmos Hub lead at the Interchain Foundation, added:

The Stargate upgrade and release of IBC was the dawn of interoperability, now the Gravity Bridge and our collaboration to ensure bridge safety with Interchain Security cement Cosmos Hub as the bedrock for the Internet of Blockchains.
