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.
