The first on-chain DEX incubated by Bybit, Byreal, founder emilyrealfreeman stated on social media that the Byreal Command Line Interface (CLI) has been open-sourced, marking its first protocol interface designed for AI agents.Unlike ordinary API wrappers or chatbot interfaces, Byreal CLI redefines the interaction between protocols and machines from an architectural level, providing deterministic execution, intent-constrained driven operations, and an Agent functionality focused on understanding users, making the system inherently safer and more reliable. Byreal CLI offers AI Agents a complete set of three primitives: identity, wallet (asset control), and a permissionless execution environment, which can only be supported simultaneously by cryptographic technology.Agents can freely discover, execute, and learn through a single command, including one-time liquidity pool analysis (APR estimation, risk scoring, LP range suggestions), with documentation and interfaces designed for AI execution. The new feature Copy Farmer allows Agents to automatically replicate top liquidity provision strategies. Byreal believes that within approximately two years, DeFi trading volume will flow more through AI Agents rather than front-end interfaces, and projects that optimize protocols for Agents in advance will win the routing layer, while those that do not keep up may become forgotten backend systems.
