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.
The verifiable crisis-response guardian for DeFi & RWA. Risk scoring and exit decisions run on-chain in Arbitrum Stylus — execution is bounded, non-custodial, and reproducibly verifiable.
CanHav uses AI agents to analyze on-chain and off-chain DeFi signals, helping users understand protocol risk in real time. The platform integrates blockchain to improve collaboration between agents.
Sigma is an on-chain portfolio risk engine — written in Stylus, verified against a Solidity baseline, and wired into a vault that lets tokenized equities behave as composable DeFi collateral on Robinhood Chain.
SAGE is a Claude-powered DeFi agent in WhatsApp. Text it to trade tokenized stocks on-chain - no app, no wallet, no gas. Funds live in a smart account you can self-custody. Built on Robinhood Chain.
Etesia Research is building institutional-grade portfolio construction infrastructure for digital assets. Our platform enables users to access systematic investment frameworks through non-custodial tokenized vaults, bringing diversification, risk management, and quantitative portfolio construction on-chain. We believe the next phase of DeFi will be defined not by access to more assets, but by better tools for allocating capital across them.
