Rent a trading agent. Never hand it the keys WARDEN is a trust layer for AI-managed tokenized stock portfolios. A user can rent a bonded trading agent from a marketplace, sign one plain policy, and let the agent operate only inside a vault that enforces the rules on-chain. If the agent tries to trade outside the policy, the vault reverts before funds move. If a monitor proves the violation, the agent's bond can be slashed and the violation is recorded on its portable reputation.
AI agents are starting to manage real financial assets, but most agentic finance products still enforce user limits in the application layer. That means the agent’s own software decides whether it is allowed to trade
WARDEN moves that rulebook on-chain
WARDEN is a trustless vault and bonded agent marketplace for tokenized stocks.
A user can rent an AI trading agent, deposit tokenized stocks into an ERC-4626 vault, and sign one policy: allowed asset, max trade size, delegated agent, expiry, and blocked trading hours. The agent can act freely inside those limits.
If it breaks them, the vault reverts before any stock tokens move. In the demo, Sarah holds tokenized TSLA on Robinhood Chain testnet. She allows YieldAgent to trade TSLA only, max 50 EUR per trade, with no trades between 22:00 and 06:00 CET. YieldAgent tries to trade at 01:30 CET. WARDEN rejects the transaction with TradingWindowClosed(). No TSLA leaves the vault. A monitor submits the proof, agent collateral is slashed, and the agent’s reputation updates on-chain. V2 adds the marketplace layer: YieldAgent is listed in AgentMarketplace with official TSLA asset scope, official USDG fee token, a 50 bps usage fee, and a minimum bond requirement. Good agents can earn fees after allowed execution. Bad agents lose bond and reputation.
WARDEN turns AI-agent trust into contract-enforced policy and market-priced accountability.
