Fixed-rate USDG lending against tokenized stocks on Robinhood Chain 24/7
Nefarious is the AI-agent-ready data and trading layer for Robinhood Chain. We run our own Nitro node and a real-time Rust indexer that decodes every trade on the chain, from Uniswap V2/V3/V4 pools to Pools.Trade and Pons bonding curves. Through a public MCP server, any AI agent (Claude, Cursor or a custom agent) can plug into Robinhood Chain in one line, with no API key. It can search tokens, read prices, candles, liquidity, holders, trending tokens and fresh launches, then quote and execute swaps. Every quote is checked by simulating it from the user's own wallet, and our servers never hold keys: the agent or the user signs, and we relay. Swaps are paid in USDG, Robinhood Chain's dollar, and users don't need ETH to trade: they sign a USDG authorization and we cover the gas, charging only its cost in USDG. The same data and swap APIs are open to developers building wallets, bots and dashboards. Nefarious turns Robinhood Chain into a market that agents can read and trade on their own.
Everyone is building AI agents that can trade. Almost nobody is building the part that stops them. AgentVault is agent permission and risk infrastructure on Robinhood Chain. A Genesis Agent NFT owns an isolated smart account governed by a deterministic risk engine the agent cannot override — the AI proposes, code decides. Live on testnet: five verified contracts, 126 tests, and no admin key anywhere in the system.
A PvP trading arena in the browser, on Robinhood Chain. Your leveraged position is a cell in a pit; its size telegraphs your collateral, a stock token, and every other trader in the arena is trying to take it.
An onchain permission check for Robinhood Chain: before value moves, a contract can refuse a token whose verdict is missing, unknown, stale or unsafe.
Deterministic option pricing on Arbitrum Stylus. Black-Scholes, five Greeks, CRR lattices and implied volatility in integer fixed point, with no floating point in the deployed artifact.
Crash insurance for your coins and stocks, and a weekly income for cash. Every price comes from a small AI model that runs on-chain on Arbitrum Stylus, so anyone can check it.
Lifelong USDG income for migrant workers' parents. A Stylus actuary prices each pension on-chain from UN life tables in one call; savings earn in S&P 500 and T-bills on Robinhood Chain.
An agent harvests tax losses on Robinhood tokenized stocks, bounded by an onchain mandate it can't exceed. Stylus HIFO ledger, contract-enforced wash-sale wall, slashable bond. Robinhood Chain.
Tokenized stocks on Robinhood Chain at the best single pool's price or better, floored against Chainlink, and no ETH needed to trade.
Egress protects people who lend money against tokenized stocks. It checks onchain how much of a stock could actually be sold in a crash. If loans grow bigger than the market can absorb, it automatically stops new lending on that stock before lenders are left with losses.
