Non-custodial lending infrastructure for tokenized real-world assets, built on Robinhood Chain Testnet and Arbitrum.
Prediction market but everyone is winner.
Agentic invoice escrow on Arbitrum with x402 payments, AP2-style mandates, ERC-8004-style reputation, TEE validation, service bonds, dispute evidence, and settlement receipts.
Grant a budget once in MetaMask — hire an autonomous AI research team that buys its own intelligence, data, and gas.
The first permission-based AI yield optimizer using Smart Accounts, ERC-7710 sub-delegations, and x402 micropayments
Pay-per-prompt AI marketplace: connect your wallet, grant one spend permission, then pay only for the prompts you send via automatic on-chain micro-payments.
ArbiCycle is a trustless rotating savings circle (Ajo / Chama / Stokvel) on Arbitrum. 500M people worldwide save this way through one coordinator who can disappear with the pot — ArbiCycle replaces that coordinator with smart contracts. Chainlink VRF picks the payout order provably fairly, Chainlink Automation triggers rotations and penalties autonomously, and idle contributions earn yield on Aave v3. Defaulters are auto-kicked and their on-chain reputation drops. Live on Arbitrum Sepolia, deployable to Robinhood Chain. The tradition stays — the single point of failure goes
The world's first DeFi on-chain Credit Default Swap for RWA tokens.

ArbiGuard is an autonomous risk firewall for tokenized-asset protocols. It scores live transactions on-chain in a Stylus risk engine, enforces protocol-signed risk policies, and trips a hysteresis circuit breaker the moment an exploit pattern crosses a blocking threshold — then writes the threat signature to a shared registry so every other protected pool is immunized against the same attack. Built for the capital coming to Arbitrum and Robinhood Chain, where a single exploit on tokenized equities is a regulatory event, not just a TVL loss.
Autonomous AI-managed tokenized-stock index fund on Robinhood Chain. ERC-4626 vault with an LLM portfolio manager bounded by on-chain guardrails.
DelegaPay gives AI agents a bounded USDC budget using MetaMask EIP-7715, simulated x402 risk gates, and 1Shot relayer execution, ensuring AI transacts safely without private keys.
