This podcast explores the concept of cross-chain interoperability through the introduction of Axelar, a decentralized blockchain network that enables communication and interaction between different software stacks, including EVM and Cosmos. It delves into Sommelier, a decentralized active strategy manager that combines Ethereum DeFi and Cosmos Tech to optimize yield across chains, revolutionizing cross-chain yield optimization. The discussion highlights the challenges of bridging assets and tokens across different blockchain ecosystems and introduces Axelar's General Message Passing (GMP) as a solution that facilitates data transfers over token transfers, enhancing security and user experience. The podcast also covers the integration between Axelar and Arbitrum, a layer two protocol, emphasizing the importance of interoperability between diverse ecosystems and the ability to bridge between EVM and non-EVM chains. Furthermore, it emphasizes the role of Axelar in the long-term vision of Cosmos and the Arbitrum ecosystem's decision to expand to Sommelier.
