pmwallets — Python SDK for PMWallets

Official Python client for PMWallets: the Polymarket smart-money leaderboard computed from the Polygon chain, and the real-time fills of the Polymarket wallets you follow — delivered in order, exactly once, with every gap replayed.

中文说明 · Node.js SDK: pmwallets-node · Ready-to-run copy-trading bot built on it: polymarket-copy-trading-bot-python

Install

pip install pmwallets     # Python ≥ 3.10

Create an API key on pmwallets.com/keys.

Usage

import asyncio
from pmwallets import AsyncClient, Client, FillStream, FileStateStore

# synchronous REST
with Client(api_key="pmw_...") as pmw:
    board = pmw.leaderboard(minWinLo=0.55, minEligible=30, style="taker", status="active", limit=50)
    pmw.subscribe(board["rows"][0]["entityId"], channels=["ws"])   # billed per entity per hour

# every fill of every entity you follow
async def main():
    async with AsyncClient(api_key="pmw_...") as pmw:
        stream = FillStream(
            client=pmw,
            store=FileStateStore("stream.json"),     # a restart resumes exactly where it stopped
            on_fill=lambda fill, meta: print(meta.source, fill["side"], fill["price"], fill["tokenId"]),
        )
        await stream.run()

asyncio.run(main())

What is in it

One stream per account. An API-key connection takes priority over the pmwallets.com feed page (the page never takes the stream from it); between two API connections the newest wins, so run one consumer per account. HTTPS_PROXY is honoured.

PMWallets' servers are in the United Kingdom: a consumer hosted in the UK or elsewhere in Europe receives fills soonest.
