Polymarket Proxy wallet redeem SDK - Execute redeem operations on Polymarket using proxy wallets

Project description

poly-web3

Python SDK for Polymarket Proxy wallet redeem operations. Supports executing Conditional Token Fund (CTF) redeem operations on Polymarket through proxy wallets, Free gas.

English | 中文

About the Project

This project is a Python rewrite of Polymarket's official TypeScript implementation of builder-relayer-client, designed to provide Python developers with a convenient tool for executing proxy wallet redeem operations on Polymarket.

Important Notes:

  • This project only implements the official redeem functionality, focusing on Conditional Token Fund (CTF) redeem operations
  • Other features (such as trading, order placement, etc.) are not within the scope of this project

Some Polymarket-related redeem or write operations implemented in this project depend on access granted through Polymarket's Builder program. To perform real redeem operations against Polymarket, you must apply for and obtain a Builder key/credentials via Polymarket's official Builder application process. After approval you will receive the credentials required to use the Builder API—only then will the redeem flows in this repository work against the live service. For local development or automated tests, use mocks or testnet setups instead of real keys to avoid exposing production credentials.

Reference:

Current Status:

  • Proxy Wallet - Fully supported for redeem functionality
  • 🚧 Safe Wallet - Under development
  • 🚧 EOA Wallet - Under development

We welcome community contributions! If you'd like to help implement Safe or EOA wallet redeem functionality, or have other improvement suggestions, please feel free to submit a Pull Request.

Features

  • ✅ Support for Polymarket Proxy wallet redeem operations (currently only Proxy wallet is supported)
  • ✅ Check if conditions are resolved
  • ✅ Get redeemable indexes and balances
  • ✅ Support for standard CTF redeem and negative risk (neg_risk) redeem
  • ✅ Automatic transaction execution through Relayer service

Installation

pip install poly-web3

Or using uv:

uv add poly-web3

Requirements

  • Python >= 3.11

Dependencies

  • py-clob-client >= 0.25.0 - Polymarket CLOB client
  • py-builder-relayer-client >= 0.0.1 - Builder Relayer client
  • web3 == 6.8 - Web3.py library
  • eth-utils == 5.3.1 - Ethereum utilities library

Quick Start

Basic Usage - Execute Redeem

import os
import dotenv
from py_builder_relayer_client.client import RelayClient
from py_builder_signing_sdk.config import BuilderConfig
from py_builder_signing_sdk.sdk_types import BuilderApiKeyCreds
from py_clob_client.client import ClobClient
from poly_web3 import RELAYER_URL, PolyWeb3Service

dotenv.load_dotenv()

# Initialize ClobClient
host = "https://clob.polymarket.com"
chain_id = 137  # Polygon mainnet
client = ClobClient(
    host,
    key=os.getenv("POLY_API_KEY"),
    chain_id=chain_id,
    signature_type=1,  # Proxy wallet type
    funder=os.getenv("POLYMARKET_PROXY_ADDRESS"),
)

client.set_api_creds(client.create_or_derive_api_creds())

# Initialize RelayerClient
relayer_client = RelayClient(
    RELAYER_URL,
    chain_id,
    os.getenv("POLY_API_KEY"),
    BuilderConfig(
        local_builder_creds=BuilderApiKeyCreds(
            key=os.getenv("BUILDER_KEY"),
            secret=os.getenv("BUILDER_SECRET"),
            passphrase=os.getenv("BUILDER_PASSPHRASE"),
        )
    ),
)

# Create service instance
service = PolyWeb3Service(
    clob_client=client,
    relayer_client=relayer_client,
    rpc_url="https://polygon-bor.publicnode.com",  # optional
)

# Execute redeem operation
condition_id = "0xc3df016175463c44f9c9f98bddaa3bf3daaabb14b069fb7869621cffe73ddd1c"
redeem_result = service.redeem(condition_id=condition_id)
print(f"Redeem result: {redeem_result}")

# Redeem all positions that are currently redeemable
redeem_all_result = service.redeem_all()
print(f"Redeem all result: {redeem_all_result}")

Optional - Query Operations

Before executing redeem, you can optionally check the condition status and query redeemable balances:

# Check if condition is resolved
condition_id = "0xc3df016175463c44f9c9f98bddaa3bf3daaabb14b069fb7869621cffe73ddd1c"
can_redeem = service.is_condition_resolved(condition_id)

# Get redeemable indexes and balances
redeem_balance = service.get_redeemable_index_and_balance(
    condition_id, owner=client.builder.funder
)

print(f"Can redeem: {can_redeem}")
print(f"Redeemable balance: {redeem_balance}")

API Documentation

PolyWeb3Service

The main service class that automatically selects the appropriate service implementation based on wallet type.

Methods

is_condition_resolved(condition_id: str) -> bool

Check if the specified condition is resolved.

Parameters:

  • condition_id (str): Condition ID (32-byte hexadecimal string)

Returns:

  • bool: Returns True if the condition is resolved, otherwise False
get_winning_indexes(condition_id: str) -> list[int]

Get the list of winning indexes.

Parameters:

  • condition_id (str): Condition ID

Returns:

  • list[int]: List of winning indexes
get_redeemable_index_and_balance(condition_id: str, owner: str) -> list[tuple]

Get redeemable indexes and balances for the specified address.

Parameters:

  • condition_id (str): Condition ID
  • owner (str): Wallet address

Returns:

  • list[tuple]: List of tuples containing (index, balance), balance is in USDC units
redeem(condition_id: str, neg_risk: bool = False, redeem_amounts: list[int] | None = None)

Execute redeem operation.

Parameters:

  • condition_id (str): Condition ID
  • neg_risk (bool): Whether it's a negative risk redeem, defaults to False
  • redeem_amounts (list[int] | None): Amount list for negative risk redeem, must contain 2 elements

Returns:

  • dict: Transaction result containing transaction status and related information

Examples:

# Standard CTF redeem
result = service.redeem(condition_id="0x...")

# Negative risk redeem
result = service.redeem(
    condition_id="0x...",
    neg_risk=True,
    redeem_amounts=[1000000, 2000000]  # Amounts in smallest unit (6 decimal places)
)
redeem_all() -> list[dict] | None

Redeem all positions that are currently redeemable for the authenticated account.

Returns:

  • list[dict] | None: List of redeem results, or None if no redeemable positions

Examples:

# Redeem all positions that can be redeemed
service.redeem_all()

Notes

  1. Environment Variable Security: Make sure .env file is added to .gitignore, do not commit sensitive information to the code repository
  2. Network Support: Currently mainly supports Polygon mainnet (chain_id: 137), Amoy testnet may have limited functionality
  3. Wallet Type: Currently only Proxy wallet is supported (signature_type: 1), Safe and EOA wallet redeem functionality is under development
  4. Gas Fees: Transactions are executed through Relayer, gas fees are handled by the Relayer
