Herd provides an AI-enabled "coterminal" platform that allows users—both human and AI—to search, compose, and interact with smart contracts across the blockchain ecosystem. It introduces "trails," a no-code abstraction layer that simplifies composing sequences of contract functions into reusable flows, enabling users to build apps, automations, and sandboxed experiences without coding. Each trail can integrate with on-chain contracts instantly, remain version-aware, and be shared or forked freely. The platform’s conversational interface connects powerful on-chain search with LLM assistance, intended to unlock deeper engagement with composable crypto protocols.
