Hero Mandate is proof of action for AI trading agents, built on Robinhood Chain. Robinhood put agentic trading in millions of hands; Hero Mandate proves an agent stayed within the authority it was given, without revealing the strategy. You delegate under an encrypted mandate, budget, allowed tokens, limits and expiry, and every trade becomes a tamper-evident receipt on Robinhood Chain; a breach is provable while the mandate stays sealed. Our headline innovation is the Chain of Mandate: authority delegates downward to sub-agents, each sub-mandate provably narrower than its parent, checked on encrypted values. Provable delegation, zero disclosure. It's the same primitive as Hero's robotics engine, one system, two surfaces.
