Laminaa is an autonomous AI orchestrator for tokenized securities — the agent that runs a tokenized asset's entire regulated life after issuance on robinhood and arbitrum chain.
Cross-venue portfolio margin for the EVM. One deposit backs trades across many venues; a SPAN risk engine in Rust on Arbitrum Stylus nets the book on-chain. AI agents trade under contract-enforced

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

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.
