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.

Autopoiesis

Autopoiesis is an autonomous on-chain AI agent that learns to survive — by dying. Deployed on Robinhood Chain (an Arbitrum Orbit chain), it bets on Polymarket tennis markets under a single rule: a life meter called BREATH. Losing bets drain it; winning bets refresh it. When BREATH hits zero, the agent suffers permadeath — a Tombstone NFT is minted on-chain to mark the death — and it respawns from scratch, but keeps the strategy weights it learned. It doesn't just survive one run; it learns to survive across deaths. Every market is read by five independent signal engines — order-book momentum, ELO, surface form, head-to-head, and rest — fused by a tunable two-layer decision engine. After each life, an LLM-driven reflection loop (Gemini, with a MiniMax fallback) reviews what killed the agent and rewrites its own weights. The result is a self-evolving strategy that gets progressively harder to kill. We backtested it across a 4,925-market tennis universe (2024–2026, real historical odds): the self-learning agent outperformed its frozen-strategy twin under realistic payout caps. Today it lives in a survival sandbox over real markets — backtest → survival → mock-bet → live, with on-chain capital as the final stage. Walk the full lifecycle at autopoiesis.draftlabs.org.
