polymarket-trading

name	polymarket-trading
description	Use when the user wants to actually PLACE, manage, or redeem bets on Polymarket (not just read odds — that's the blockrun_predexon_* data tools). Covers setup (deposit wallet, funding, approvals), buy/sell with confirm gating, positions, redeeming winnings, geoblock handling, and the end-to-end flow.

Polymarket Trading (blockrun_polymarket)

Real-money trading on Polymarket's CLOB V2 (Polygon), signed locally by the user's ClawRouter wallet key. Data discovery stays on the blockrun_predexon_* tools — blockrun_polymarket only trades.

Mental model

• Signer = the ClawRouter wallet key (~/.openclaw/blockrun/wallet.key, or BLOCKRUN_WALLET_KEY) — the SAME wallet that pays for LLM calls. Never leaves the machine.
• Deposit wallet = a Polygon vault contract derived from that key (POLY_1271). It holds the betting funds in pUSD and only honors the signer's EIP-712 signatures. Deploy/approve/redeem are gasless (relayer).
• Money separation: bets spend pUSD on Polygon; x402 API fees spend USDC on Base — but both come from the ONE ClawRouter wallet. The x402 budget ledger does NOT cover bets — confirm:true + caps do.
• Zero setup: no Polymarket account, no API keys, no gas token. On first setup ClawRouter bootstraps a builder key from the user's OWN wallet, then derives + deploys the vault (all gasless). Geoblock is handled by default — CLOB traffic routes through BlockRun's Tokyo egress out of the box.

Golden rules for agents

1. Never pass confirm:true unless the user explicitly approved that exact trade. Call once WITHOUT confirm → show the dry-run preview → ask → re-call with confirm:true.
2. Per-order cap POLYMARKET_MAX_BET_USD (default $25) and optional session cap are enforced locally; don't try to split orders to sneak past them.
3. On ANY error, read the message — it says exactly what to do next (fund, approve, region, re-run setup). Don't retry blindly.

End-to-end flow

# 0. No Polymarket account or API keys needed — ClawRouter bootstraps everything
#    from the user's own wallet on first setup. (Set POLYMARKET_CLOB_HOST to a
#    permitted-region egress only if the user is in a geoblocked region.)

# 1. Provision + inspect (idempotent, safe to re-run any time)
blockrun_polymarket action:"setup"
# → deposit wallet address + funding instructions + region status

# 2. Fund the vault from the user's Base USDC — gasless x402, one call ($0.01 fee,
#    non-custodial). pUSD credit is ASYNC (minutes) — re-run setup to watch it. Min $2.
blockrun_polymarket action:"fund" amount_usd:5             # dry-run preview
blockrun_polymarket action:"fund" amount_usd:5 confirm:true

# 3. Sign the one-time gasless approval batch (after user consent)
blockrun_polymarket action:"setup" confirm:true

# 4. Find a market + token (data tool, paid data)
blockrun_predexon_markets ...   # → clobTokenIds, conditionId (Polymarket /v1/pm data)

# 5. Preview, then place
blockrun_polymarket action:"buy" token_id:"..." amount_usd:2            # dry-run
blockrun_polymarket action:"buy" token_id:"..." amount_usd:2 confirm:true  # market FOK
#   or limit: price:0.45 size:10 (GTC; order_type:"GTD" + expires_at for expiry)
#   or via condition: condition_id:"0x..." outcome:"Yes"

# 6. Manage
blockrun_polymarket action:"orders"                     # open orders
blockrun_polymarket action:"cancel" order_id:"..."      # or all:true
blockrun_polymarket action:"positions"                  # holdings + PnL + redeemable

# 7. Claim winnings after resolution (gasless)
blockrun_polymarket action:"redeem" condition_id:"0x..."             # preview
blockrun_polymarket action:"redeem" condition_id:"0x..." confirm:true

# 8. Cash out — pUSD → native USDC on Base, back to the user's agent wallet
blockrun_polymarket action:"withdraw"                                # dry-run (full balance)
blockrun_polymarket action:"withdraw" confirm:true                   # (partial: amount_usd:5)

Order semantics

• Prices are probabilities 0–1, auto-rounded to the market's tick grid.
• Market buy = amount_usd (dollars). Market sell = size (shares).
• Limit orders: price + size; default GTC; post_only:true for maker-only.
• FOK fails whole-or-nothing; FAK fills what it can. On "FOK not filled", offer FAK or a limit at the shown book price.

Regions / geoblock

Order placement is IP-geoblocked (US/UK/EU + many regions). Handled by default — CLOB traffic routes through BlockRun's Tokyo egress, so setup reports ✅ Region: order placement permitted out of the box; you don't need to do anything. A user can override with POLYMARKET_CLOB_HOST (their own relay), or POLYMARKET_CLOB_PROXY / HTTPS_PROXY. Respecting Polymarket's ToS for the user's jurisdiction is the user's responsibility — never suggest evading it.

Troubleshooting

• "No deposit wallet configured" → run action:"setup".
• "No ClawRouter wallet found" → generate one via the /wallet command (or set BLOCKRUN_WALLET_KEY) before trading.
• No manual creds are ever needed — ClawRouter bootstraps its builder key from the user's own wallet on first setup. (Advanced: POLYMARKET_SIG_TYPE=0 = plain EOA mode; needs POL gas + pUSD in the EOA, and is read-only for orders.)
• Balance/allowance errors right after funding → setup again (refreshes the CLOB's balance cache).
• 403 → region issue; see setup's region line.
• "order signer address has to be the address of the API KEY" → auto-recovered once (creds re-derived); if persistent, setup, then consider POLYMARKET_SIG_TYPE=0 (upstream clob-client-v2 issue #65).
