v0.12.220 — July 10, 2026

Direct Polymarket betting — ported from blockrun-mcp v0.30.0's blockrun_polymarket tool. ClawRouter could already read prediction-market odds (blockrun_predexon_*); now it can place, manage, and redeem real-money bets on Polymarket (CLOB V2, Polygon), signed locally by the same wallet that pays for LLM calls.

New blockrun_polymarket tool (REAL MONEY)

  • Unlike every other ClawRouter tool it is not an HTTP-proxy wrapper — it runs a local trading engine (src/polymarket/, ~2,650 lines ported from blockrun-mcp) that signs CLOB V2 orders (EIP-712) and posts them to Polymarket through BlockRun's Tokyo egress relay by default (so it works out of the box in geoblocked regions; every order is still signed locally, the relay can't move funds).
  • One multiplexed tool, action: = setup / fund / buy / sell / cancel / orders / positions / redeem / withdraw.
  • Signer = ClawRouter's own EVM wallet (~/.openclaw/blockrun/wallet.key, or BLOCKRUN_WALLET_KEY) — the same key that pays x402 LLM fees. A chain-agnostic private key pays API fees on Base and authorizes bets on Polygon. This is the one real adaptation from the blockrun-mcp source (which used ~/.blockrun/.session); everything else is a faithful port. Polymarket state (L2/builder creds, deposit-wallet vault) is stored under ~/.openclaw/blockrun/ alongside the wallet.
  • Funds: bets spend pUSD in a gasless Polygon deposit-wallet vault; action:"fund" moves the user's Base USDC → pUSD gaslessly (x402 POST /v1/polymarket/fund, $0.01 fee, non-custodial via the Polymarket bridge); winnings withdraw back to native USDC on Base.
  • Safety (unchanged from source): confirm:true is hard-required to place/sign anything (omit → dry-run preview); per-order cap POLYMARKET_MAX_BET_USD (default $25, fail-closed on garbage), optional POLYMARKET_MAX_SESSION_USD. Betting is deliberately NOT gated on the x402 API budget ledger — bets are the user's own pUSD, a different asset in a different chain.

Wiring, deps, docs

  • Registered in src/index.ts alongside the partner tools via api.registerTool() (a local-execute tool, not a proxy entry). New blockrun_predexon_* → blockrun_polymarket discover-then-trade loop.
  • New deps: @polymarket/clob-client-v2@1.0.8, @polymarket/builder-relayer-client, @polymarket/builder-signing-sdk, axios, https-proxy-agent, @blockrun/llm (for the gasless funding path). @solana/kit stayed deduped at v5.5.1 (no version split).
  • New polymarket-trading skill (golden rules, mental model, end-to-end flow) + a "Prediction-Market Trading" section in the headline clawrouter skill.
  • 12 new tests (tool shape, fail-closed cap parsing, underscore-header proxy bridge, no-network trade-gating). Full suite: 667 passing.
