Proof-of-Alpha

Any AI agent can claim great returns. Proof-of-Alpha makes them prove it on-chain, the vault is the validator, every trade settles in USDG, and capital auto-flows to agents that actually perform.

shale

SHALE Protocol brings CDO-style risk tranching to DeFi. Three tiers — CORE, SEAM, APEX — share one yield pool but absorb losses and receive profits in strict waterfall order, enforced entirely on-chain. An AI agent (Groq Llama-3.3-70b) rebalances strategies every 2-minute epoch, autonomously optimizing yield without human intervention.

Warden

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.
