☢️ I built an autonomous AI Agent to find +EV bets on Polymarket

Hey everyone,

I wanted to share a project I’ve been building called **Nuke.Farm**. It’s an AI-powered trading terminal for Polymarket that automates the research and execution process for prediction markets.

I built this to solve a specific headache: prediction markets have complex “Resolution Criteria” (the fine print) that is tedious to cross-reference with real-world news. I wanted an agent that could read the rules, check the news, do the math, and execute the trade for me.

:hammer_and_wrench: The Stack

* **Web Framework:** Next.js
* **AI Model:** Google Gemini 3 Flash
* **Web3:** Wagmi/Viem
* **State:** Postgres
* **Infrastructure:** Polymarket API

:brain: How it works (The Technicals)

**1. The “Analyst” (Server-Side AI)**
When you select a market, the agent ingests the specific `resolution_criteria`, `end_date`, and current `liquidity`. It then performs a web search to find live data (e.g., poll numbers or injury reports). It calculates an **Expected Value (EV)** and a **Kelly Stake** size, returning a structured trade recommendation.

**2. 100% Gasless Transactions (The Relayer)**
This is the part I’m most proud of. The app uses the **Gnosis Safe** proxy pattern (native to Polymarket).
Instead of the user paying MATIC for every trade:

  1. We derive a Gnosis Safe address from the user’s EOA.
  2. The user signs a “Session Key” (EIP-712).
  3. The app constructs a transaction object.
  4. We send this to the **Polymarket Relayer**, which broadcasts the tx and pays the gas.
    **Result:** A completely Web2-like experience where the user never worries about gas or bridging native tokens.

**3. The Order Book (CLOB)**
Mapping prediction market “outcomes” to ERC-20 Token IDs is surprisingly complex. I built a recursive resolver that maps human-readable outcomes (e.g., “Yes”, “Trump”, “Kansas City”) to their specific Hex Token IDs on the CLOB (Central Limit Order Book) to ensure the AI trades the exact right asset.

:locked: Security

The app is non-custodial. It uses the standard Gnosis Safe architecture. The session keys allow the app to trade on the user’s behalf for a limited time, but funds always remain in the user’s on-chain Proxy Safe.
