ChatAndBuild

ChatAndBuild is a no-code application builder on BNB Chain: users describe what they want in natural language and models produce the front-end interface, contract logic and deployment scripts, with prompts accepted in more than 40 languages. What sets it apart is how output is owned. Each generated app maps to an NFA, a non-fungible agent, where the prompt hash, model version and artifact fingerprint are written onchain through Proof-of-Prompt to form a traceable record of generation.

Its users are independent developers and small teams without contract or front-end capacity, facing outputs that are hard to verify, price or inherit. BAP-578 defines the agent asset structure at the application layer and runs alongside ERC-8004, which governs cross-protocol registration and reputation interfaces. After the standard text was published in February 2026, the project shipped a commercial skill package in March that bakes payment, subscription and permission templates into the build flow.
