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.
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:
- Polymarket Builders — Introduction: https://docs.polymarket.com/developers/builders/builder-intro
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 clientpy-builder-relayer-client >= 0.0.1- Builder Relayer clientweb3 == 6.8- Web3.py libraryeth-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: ReturnsTrueif the condition is resolved, otherwiseFalse
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 IDowner(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 IDneg_risk(bool): Whether it's a negative risk redeem, defaults toFalseredeem_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, orNoneif no redeemable positions
Examples:
# Redeem all positions that can be redeemed
service.redeem_all()

Notes
- Environment Variable Security: Make sure
.envfile is added to.gitignore, do not commit sensitive information to the code repository - Network Support: Currently mainly supports Polygon mainnet (chain_id: 137), Amoy testnet may have limited functionality
- Wallet Type: Currently only Proxy wallet is supported (signature_type: 1), Safe and EOA wallet redeem functionality is under development
- Gas Fees: Transactions are executed through Relayer, gas fees are handled by the Relayer
Development
Install Development Dependencies
uv pip install -e ".[dev]"
