Interoperability protocol Axelar has enabled Sommelier, a yield optimization protocol on Cosmos, to become a cross-chain application by connecting it with Ethereum Layer 2 network Arbitrum One.

Sommelier’s DeFi vaults operate on Sommelier’s own blockchain in the Cosmos ecosystem and Ethereum, and now they will be available on Arbitrum.

Sommelier will utilize Axelar’s General Message Passing (GMP) protocol, which facilitates communication between the Cosmos ecosystem and blockchains that support Ethereum-based smart contracts, like Arbitrum.

The communication protocol enables data and assets to move between the two ecosystems, making it possible for cross-chain apps to operate.
