It provides both a CLI interface for quick deployment and a framework API for custom implementations. By leveraging AI-powered agents and swarm optimization, JuliaOS enables sophisticated strategies across multiple blockchains. +**๐Ÿ†• New Storage Enhancements**: JuliaOS now supports decentralized storage backends including IPFS and Arweave, enabling agents to store and share data across distributed networks.
