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

poly-web3

Python SDK for redeeming and splitting/merging Polymarket positions via Proxy/Safe wallets (gas-free).

English | 中文

Python >= 3.11
pip install poly-web3

from poly_web3 import PolyWeb3Service

service = PolyWeb3Service(
    clob_client=client,
    relayer_client=relayer_client,
)

# Redeem all redeemable positions for the current account.
service.redeem_all(batch_size=10)

# Split/Merge for binary markets (amount in human USDC units).
service.split("0x...", 10)
service.merge("0x...", 10)

Redeem Behavior Notes

• Redeemable positions are fetched via the official Positions API, which typically has ~1 minute latency.
• redeem_all returns an empty list if there are no redeemable positions. If the returned list contains None, the redeem failed and should be retried.

Split/Merge Notes

• split/merge are designed for binary markets (Yes/No) and use the default partition internally.
• amount is in human units (USDC), and is converted to base units internally.

FAQ

1. UI shows redeemable, but redeem_all returns []: The official Positions API can be delayed by 1–3 minutes. Wait a bit and retry.
2. RPC error during redeem: Switch RPC endpoints by setting rpc_url when instantiating PolyWeb3Service.
3. Redeem stuck in execute: The official relayer may be congested. Stop redeeming for 1 hour to avoid nonce looping from repeated submissions.
4. Relayer client returns 403: You need to apply for Builder API access and use a valid key. Reference: Polymarket Builders — Introduction: https://docs.polymarket.com/developers/builders/builder-intro
5. Relayer daily limit: The official relayer typically limits to 100 requests per day. Prefer batch redeem (batch_size) to reduce the number of requests and avoid hitting the limit.

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 and Safe wallet redeem operations on Polymarket.

Important Notes:

• This project implements official CTF redeem plus binary split/merge 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.

Current Status:

• ✅ Proxy Wallet - Fully supported for redeem/split/merge
• ✅ Safe Wallet - Fully supported for redeem/split/merge
• 🚧 EOA Wallet - Under development

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

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

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 (signature_type=2 for Safe)
    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
)


# Redeem all positions that are currently redeemable
redeem_all_result = service.redeem_all(batch_size=10)
print(f"Redeem all result: {redeem_all_result}")
# If redeem_all_result contains None, refer to README FAQ and retry.
if redeem_all_result and any(item is None for item in redeem_all_result):
    print("Redeem failed for some items; please retry.")

# Execute redeem operation (batch)
condition_ids = [
    "0xc3df016175463c44f9c9f98bddaa3bf3daaabb14b069fb7869621cffe73ddd1c",
    "0x31fb435a9506d14f00b9de5e5e4491cf2223b6d40a2525d9afa8b620b61b50e2",
]
redeem_batch_result = service.redeem(condition_ids, batch_size=10)
print(f"Redeem batch result: {redeem_batch_result}")
if redeem_all_result and any(item is None for item in redeem_all_result):
    print("Redeem failed for some items; please retry.")

Basic Usage - Split/Merge (Binary Markets)

# amount is in human units (USDC)
split_result = service.split(
    "0x31fb435a9506d14f00b9de5e5e4491cf2223b6d40a2525d9afa8b620b61b50e2",
    1.5,
)
print(f"Split result: {split_result}")

merge_result = service.merge(
    "0x31fb435a9506d14f00b9de5e5e4491cf2223b6d40a2525d9afa8b620b61b50e2",
    1.5,
)
print(f"Merge result: {merge_result}")

API Documentation

PolyWeb3Service

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

Methods

redeem(condition_ids: list[str], batch_size: int = 20)

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"

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}")
