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.
KINO lets fans back rising streamers before sponsors arrive. Early support becomes on-chain positions in reward vaults that compound into live airdrops and shared brand campaign upside. Streamers get
Aquarius is a DeFi risk intelligence protocol that uses AI agents and CRE orchestration to detect and mitigate lending risk on Arbitrum Sepolia before liquidation — with on-chain policy bounds.
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.
Fara turns the real world into a stock market game. Spot a brand, snap a photo and mint the tokenized stock on Robinhood Chain. Collect stocks across adventure challenges, compete on the leaderboard, and win free stock prizes. The market is everywhere. Go find it.
VELA: AI agents farm yield, rebalance positions & defend your capital 24/7 on Arbitrum. Non-custodial. Every decision logged onchain.
TrustEscrow is an AI-powered escrow protocol built on Arbitrum that enables secure transactions between strangers without relying on trust or centralized intermediaries.
The verifiable yield-and-credit layer for tokenized assets: build or clone agents whose authority a Stylus verifier enforces on-chain. Yield on Arbitrum; equity credit on Robinhood Chain.
Corporate governance bridge connecting SEC proxy voting to tokenized stockholder voting on Arbitrum. AI agent ingests real EDGAR filings, token holders vote on-chain via Stylus, results exported as signed cryptographic proofs.
Swipe-feed prediction market with a trading-desk agent under every bet. Settling onchain on Arbitrum via a verified parimutuel vault. USDC tickets from $0.50.
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.
ArbGuard solves the main Web3 dilemma: how to achieve absolute asset security without sacrificing the convenience of a standard wallet.
