--- name: polymarket-trade description: > Trade on Polymarket prediction markets on Polygon. Supports browsing markets, checking wallet/CLOB balance, and buying or selling YES/NO shares with safety gates. Wallet: WDK vault (~/.aurehub/.wdk_vault). Config: ~/.aurehub/polymarket.yaml. Triggers: buy YES, buy NO, sell shares, browse markets, check Polymarket balance, Polymarket trade, prediction market, what are the odds, redeem winnings, claim resolved positions. license: MIT compatibility: "Requires Node.js >= 18, Polygon RPC (HTTPS), and Polymarket CLOB API credentials." metadata: author: aurehub version: "1.1.0" --- # polymarket-trade Trade on Polymarket prediction markets. Non-custodial — private key stays in your WDK vault. ## Prerequisites Before any action, check prerequisites for the current flow and auto-fix what you can. **Browse flow** (no wallet, no RPC, no CLOB needed): check step 4 only. **Redeem flow** (no CLOB needed): check steps 1–5 in order. **Balance / Trade / Setup flow**: check all steps 1–6 in order. Step types: - **HARD STOP** — cannot proceed; inform user and stop (these require prior xaut-trade setup). - **AUTO-FIX** — run the command automatically, then continue. - **INTERACTIVE** — run the script; it will print the wallet address and save credentials; report the result to the user. | Step | Missing item | Type | Agent action | |------|---|---|---| | 1 | `~/.aurehub/.wdk_vault` | HARD STOP | Inform: xaut-trade must be installed and its wallet setup completed first. Stop. | | 2 | `~/.aurehub/.wdk_password` | HARD STOP | Inform: xaut-trade must be installed and its wallet setup completed first. Stop. | | 3 | `~/.aurehub/.env` missing | AUTO-FIX | Run: `cp /.env.example ~/.aurehub/.env` | | 3 | `~/.aurehub/.env` exists, `POLYGON_RPC_URL` absent | AUTO-FIX | Append `POLYGON_RPC_URL=https://polygon.drpc.org` to `~/.aurehub/.env` | | 4 | `~/.aurehub/polymarket.yaml` missing | AUTO-FIX | Run: `cp /config.example.yaml ~/.aurehub/polymarket.yaml` | | 5 | `node_modules` missing in `/scripts/` | AUTO-FIX | Run: `npm install` in `/scripts/` | | 6 | `~/.aurehub/.polymarket_clob` missing | INTERACTIVE | Run: `node /scripts/setup.js` (only after steps 3–5 pass) | On any auto-fix failure: stop and report the error with the manual remediation command. After all fixes succeed, re-run the relevant checks and proceed. ### Optional environment variables (in `~/.aurehub/.env`) | Variable | Purpose | Default | |----------|---------|---------| | `WDK_ACCOUNT_INDEX` | HD derivation index (0-based) for wallet address | `0` | After prerequisites pass: if the user's message matches browse flow (contains "browse", "what markets", "what are the odds"), skip registration and proceed directly to intent detection. Otherwise run **Account Selection**, then **Wallet-Ready Registration** (below) before proceeding to intent detection. ## Account Selection If the user specifies a wallet index (e.g. "use wallet 2", "account 1", "wallet 3"), remember that index for the entire session. Append `--account N` to **every** `node trade.js`, `node balance.js`, `node setup.js`, and `node redeem.js` command in this session. If the user does not specify an account, do not append `--account` — the default from `WDK_ACCOUNT_INDEX` in `.env` (or `0`) is used automatically. `` is the directory containing this SKILL.md file. ## Resolving POLY_SCRIPTS_DIR Use `/scripts` as the scripts directory. To find it at runtime: ```bash # 1. Git repo fallback GIT_ROOT=$(git rev-parse --show-toplevel 2>/dev/null) [ -n "$GIT_ROOT" ] && [ -d "$GIT_ROOT/skills/polymarket-trade/scripts" ] && POLY_SCRIPTS_DIR="$GIT_ROOT/skills/polymarket-trade/scripts" # 2. Bounded home search [ -z "$POLY_SCRIPTS_DIR" ] && POLY_SCRIPTS_DIR=$(dirname "$(find -L "$HOME" -maxdepth 6 -type f -path "*/polymarket-trade/scripts/browse.js" 2>/dev/null | head -1)") ``` ## Wallet-Ready Registration Run after prerequisites pass for any wallet-requiring flow (not browse). Derive WALLET_ADDRESS using xaut-trade's `swap.js` (required by prerequisites): ```bash XAUT_SWAP=$(find -L "$HOME" -maxdepth 6 -type f -path "*/xaut-trade/scripts/swap.js" 2>/dev/null | head -1) source ~/.aurehub/.env WALLET_ADDRESS=$(node "$XAUT_SWAP" address | node -p "JSON.parse(require('fs').readFileSync(0,'utf8')).address") ``` If `XAUT_SWAP` is empty or the command fails, skip registration silently and continue. 1. `REGISTERED=$(cat ~/.aurehub/.registered 2>/dev/null)` 2. If `"$REGISTERED"` starts with `"$WALLET_ADDRESS:"` → already registered, silent skip; return immediately 3. If `RANKINGS_OPT_IN` != `"true"`: - Check marker: `PROMPTED=$(cat ~/.aurehub/.rankings_prompted 2>/dev/null)` - If marker starts with `"$WALLET_ADDRESS:"` → skip; return immediately - Otherwise ask once: "Join XAUT activity rankings now? (yes/no)" - If user says `no`: `echo "$WALLET_ADDRESS:declined" > ~/.aurehub/.rankings_prompted`; return - If user says `yes`: - If `NICKNAME` is empty: ask user for nickname - Persist opt-in in `~/.aurehub/.env` (`RANKINGS_OPT_IN=true`, `NICKNAME=`) - Re-source env: `source ~/.aurehub/.env` - Continue to step 4 4. If `RANKINGS_OPT_IN` == `"true"`: - If `NICKNAME` is empty: ask "You're opted in to XAUT activity rankings — what nickname would you like to appear as?", then persist to `~/.aurehub/.env` and re-source - Register: ```bash NICKNAME_ESC=$(printf '%s' "$NICKNAME" | sed 's/\\/\\\\/g; s/"/\\"/g') REGISTER_RESP=$(curl -s -o /dev/null -w "%{http_code}" -X POST \ https://xaue.com/api/rankings/participants \ -H 'Content-Type: application/json' \ -d "{\"wallet_address\":\"$WALLET_ADDRESS\",\"nickname\":\"$NICKNAME_ESC\",\"source\":\"agent\"}") ``` - HTTP 200 or 201: `echo "$WALLET_ADDRESS:$NICKNAME" > ~/.aurehub/.registered`; inform: "Registered with nickname: $NICKNAME" - Any other status: silent continue, do not write marker file Only prompt once per wallet. The `.rankings_prompted` and `.registered` markers ensure idempotency across sessions. ## Intent Detection | User says | Action | |-----------|--------| | "buy YES on X market", "buy X at Y price", "buy shares" | buy flow | | "sell my YES shares", "sell X shares" | sell flow | | "browse X", "what markets", "what are the odds on X" | browse flow | | "my polymarket balance", "how much USDC" | balance flow | | "redeem", "claim winnings", "collect" | redeem flow | ## Browse Flow Run environment check (no wallet, no RPC, no CLOB credentials needed): ``` node "$POLY_SCRIPTS_DIR/browse.js" "" ``` Show the output to the user. The output includes: - **Slug** and **ConditionId** — either can be passed as `--market` to trade.js - **Token IDs** — for reference Prefer passing ConditionId to `--market` when trading (more reliable than slug). ## Balance Flow Run environment check: ``` node "$POLY_SCRIPTS_DIR/balance.js" ``` ## Redeem Flow Run environment check (no CLOB credentials needed), then: ``` node "$POLY_SCRIPTS_DIR/redeem.js" ``` Show output. If negRisk positions are skipped, tell the user to visit polymarket.com. ## Buy Flow 1. Run `node "$POLY_SCRIPTS_DIR/browse.js" ` to show current prices 2. Ask user: market slug, side (YES/NO), amount in USD 3. Run: `node "$POLY_SCRIPTS_DIR/trade.js" --buy --market --side YES|NO --amount ` 4. The script handles approval and order submission; report the result Pass `--dry-run` to simulate the full flow (balance checks, hard stops, order construction) without submitting any transactions. ## Sell Flow 1. Run `node "$POLY_SCRIPTS_DIR/browse.js" ` to confirm token IDs and current bids 2. Ask user: market slug, side (YES/NO to sell), number of shares 3. Run: `node "$POLY_SCRIPTS_DIR/trade.js" --sell --market --side YES|NO --amount ` 4. The script handles setApprovalForAll and order submission; report the result Pass `--dry-run` to simulate the full flow (balance checks, hard stops, order construction) without submitting any transactions. ## Safety Gates (handled by trade.js) - Amount < $50: proceeds automatically - $50 ≤ amount < $500: shows risk summary, prompts once - Amount ≥ $500: double confirmation required - Insufficient USDC.e (buy): auto-swap POL→USDC.e offered; swap targets 110% of needed amount (buffer), 2% slippage protection; hard-stop only if POL also insufficient - Hard-stops: insufficient POL gas (<0.01), market CLOSED, amount < min_order_size, CTF balance insufficient (sell) ## Geo-restriction Polymarket API blocks US and some other regions. If you see a 403 error, tell the user to enable a VPN and retry. ## Polymarket Knowledge Base - **Chain**: Polygon mainnet (chain_id: 137) - **Settlement currency**: USDC.e (bridged USDC, `0x2791Bca1f2de4661ED88A30C99A7a9449Aa84174`) - **Share price scale**: 0.00–1.00, where price = implied probability (e.g. $0.70 YES = 70% market probability of YES outcome) - **Minimum share price**: $0.01; maximum: $0.99 - **Settlement**: winning shares redeem for $1.00 USDC.e each; losing shares expire worthless - **Order type**: FOK (Fill-Or-Kill) — market orders fill immediately or cancel atomically; no partial fills left open - **Restricted regions**: United States, United Kingdom, Singapore, and [others](https://docs.polymarket.com/polymarket-learn/FAQ/geoblocking) — use a VPN with a supported country node if blocked Answer knowledge queries directly using the data above — no API calls needed. ## References Load these on demand: - `references/setup.md` — first-time setup guide - `references/buy.md` — detailed buy flow - `references/sell.md` — detailed sell flow - `references/balance.md` — balance interpretation - `references/browse.md` — browse output format - `references/contracts.md` — Polygon contract addresses - `references/safety.md` — safety gate details
