Free for everyone. All of Nefarious (data API, swap API, MCP server) is free to use, with no API fees and no swap fees. We plan to earn revenue through MEV-related mechanisms, such as capturing backrun opportunities created by the order flow we route, never at the expense of our users: no sandwiching, and no worse prices than the quote they signed.

The problem

Robinhood Chain moves fast: 100 ms blocks, thousands of new tokens launched every day, liquidity spread across Uniswap V2/V3/V4, Pools.Trade and Pons bonding curves. For an AI agent or a developer, there is no single place to read this market in real time and trade on it. Public RPCs are rate-limited, launchpad curves are invisible to standard DEX aggregators, and every user needs ETH for gas before making a first trade.

What Nefarious does

Nefarious is the AI-agent-ready data and trading layer for Robinhood Chain.

• MCP server for AI agents: one URL (https://api.nefariouslabs.dev/mcp), no API key. Any MCP client (Claude, Cursor or a custom agent) gets 12 tools to search tokens, read prices, candles, liquidity, holders, trades, trending tokens and fresh launches, then quote, send and track swaps.

• Market data API: real-time prices, OHLC candles, liquidity, holders, trades, trending tokens and new launches across all launchpads, live over REST and WebSocket.

• Swap API: best route across Uniswap V2/V3/V4 (direct or through ETH/USDG), Pools.Trade pools, and tokens still on their Pons bonding curve. Every quote is checked by simulating the real transaction from the user's own wallet, so the amount shown is what the user receives. The API returns an unsigned transaction: our servers never hold keys. The agent or the user signs, and we can relay it through our node.

• Trading without ETH, paid in USDG: a new user holding only USDG can trade right away. They sign one USDG authorization, we cover the gas and can top their wallet up with a little ETH, and they are charged only the gas cost, in USDG. No markup.

How it works

We run a real-time indexer written in Rust that decodes every trade, launch and liquidity change as blocks arrive, backed by a full history since genesis. Quotes are computed on in-memory pool state and confirmed by simulation on our node, so routes stay fast and accurate even on pools that changed a block ago.

Why it matters

AI agents are becoming a new kind of on-chain user. Nefarious gives them, and the developers building wallets, bots and dashboards, one reliable door to read and trade the whole chain, including launchpad tokens that other tools miss. USDG is at the center of the trading experience: it is enough to start trading on Robinhood Chain, with no need to bridge ETH first.

Status and next steps

Live in production: API, MCP server and gasless USDG swaps are running on Robinhood Chain mainnet, with a first real gasless swap completed by a wallet that started with 0 ETH. Our stack is chain-agnostic by design: next, we want to bring the same agent-ready layer to other chains, starting with Arbitrum One and other Arbitrum Orbit chains, so that any AI agent can read and trade across the Arbitrum ecosystem through a single API and MCP endpoint.

A note on maturity

Everything described here was built during the buildathon sprint. It runs in production and has been proven on mainnet, but making it fully robust will take more development: hardening the infrastructure and the relayer, an external security audit, broader test coverage on live traffic, and better monitoring. That is the work we want to do next, alongside the multi-chain expansion.
