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

Optional address analysis is available for trading fee impact and PnL curves. See Address Analysis (Optional).

# required 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)
service.redeem(condition_ids=["0x..."])

# Split/Merge for binary markets (amount in human pUSD units).
service.split("0x...", 10)
service.merge("0x...", 10)
service.merge_all(min_usdc=1, batch_size=10)

# batch Split/Merge
service.split_batch([{"condition_id": "", "amount": 10}])
service.merge_batch([{"condition_id": "", "amount": 10}])

Redeem Behavior Notes

• Redeemable positions are fetched via the official Positions API, which typically has ~1 minute latency.
• redeem and redeem_all return a RedeemResult pydantic object with success_list and error_list.
• success_list keeps the raw relayer execute result structure; error_list exposes condition_id, market_slug, and error for retry/backfill.
• error_condition_ids is a shortcut list derived from error_list, so you can directly retry with service.redeem(result.error_condition_ids).

Split/Merge Notes

• split/merge are designed for binary markets (Yes/No) and use the default partition internally.
• Negative-risk markets are detected via the official Gamma markets API and are routed to the NegRisk Adapter.
• split/merge route through Polymarket's v2 CTF collateral adapter: pUSD is used as exchange collateral, while the resulting CTF token IDs match the market clobTokenIds.

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.

Reference：

• Polymarket Builders — Introduction: https://docs.polymarket.com/developers/builders/builder-intro

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.

API Documentation

PolyWeb3Service

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

Methods

redeem(condition_ids: str | list[str], batch_size: int = 20, collateral_token: str = CTF_COLLATERAL_TOKEN, wrap_redeemed_collateral: bool = True) -> RedeemResult

Execute redeem operation. When Polymarket's Positions API does not return positions for explicit condition_ids, the service falls back to on-chain CTF balance checks for non-negative-risk markets. By default, redeemed USDC.e is wrapped back into pUSD in the same relayed transaction when the payout can be computed on-chain.

Parameters:

• condition_ids (str | list[str]): Condition ID or list of condition IDs
• batch_size (int): Batch size for redeem requests
• collateral_token (str): CTF collateral token used for on-chain fallback, defaults to USDC.e
• wrap_redeemed_collateral (bool): Wrap redeemed USDC.e back to pUSD when possible

Returns:

• RedeemResult: A pydantic object with:
• success_list: Raw relayer execute result payloads for successful batches
• error_list: Failed condition entries with condition_id, market_slug, and error
• error_condition_ids: Shortcut list for retry, derived from error_list

Examples:

# Single condition redeem
result = service.redeem("0x...")

# Batch redeem
result = service.redeem(["0x...", "0x..."], batch_size=10)

redeem_all(batch_size: int = 20) -> RedeemResult

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

Returns:

• RedeemResult: Empty success_list and error_list if no redeemable positions. Partial failures are surfaced in error_list instead of returning None.

Examples:

# Redeem all positions that can be redeemed
service.redeem_all(batch_size=10)

See examples/example_redeem.py for a complete redeem example.

split(condition_id: str, amount: int | float | str, negative_risk: bool | None = None)

Split a binary (Yes/No) position. amount is in human pUSD units.

Parameters:

• condition_id (str): Condition ID
• amount (int | float | str): Amount in pUSD
• negative_risk (bool | None): Optional explicit market-type hint. When None, the SDK auto-detects via the official Gamma markets API and routes neg-risk markets to the NegRisk Adapter.

Returns:

• dict | None: Transaction result

Examples:

result = service.split("0x...", 1.25)

merge(condition_id: str, amount: int | float | str, negative_risk: bool | None = None)

Merge a binary (Yes/No) position. amount is in human pUSD units.

Parameters:

• condition_id (str): Condition ID
• amount (int | float | str): Amount in pUSD
• negative_risk (bool | None): Optional explicit market-type hint. When None, the SDK auto-detects via the official Gamma markets API and routes neg-risk markets to the NegRisk Adapter.

Returns:

• dict | None: Transaction result

Examples:

result = service.merge("0x...", 1.25)

plan_merge_all(min_usdc: int | float | str = 5, exclude_neg_risk: bool = True) -> list[MergePlanItem]

Scan all current positions and compute merge opportunities without submitting transactions.

Returns:

• list[MergePlanItem]: Each item includes condition_id, market_slug, yes_balance, no_balance, mergeable, negative_risk, and reason

Examples:

plan = service.plan_merge_all(min_usdc=5, exclude_neg_risk=True)

merge_all(min_usdc: int | float | str = 5, exclude_neg_risk: bool = True, max_markets: int = 20, batch_size: int = 10) -> MergeAllResult

Plan and optionally execute merge operations for current positions.

Parameters:

• min_usdc (int | float | str): Skip mergeable amounts below this threshold
• exclude_neg_risk (bool): Skip neg-risk markets in this first-pass bulk merge flow
• max_markets (int): Maximum number of mergeable markets to execute in one call
• batch_size (int): Maximum transactions submitted per grouped merge batch

Returns:

• MergeAllResult: Contains plan_list, success_list, error_list, and error_condition_ids

Examples:

result = service.merge_all(
    min_usdc=5,
    exclude_neg_risk=True,
    max_markets=20,
    batch_size=10,
)

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: Proxy (signature_type: 1) and Safe (signature_type: 2) are supported; EOA wallet operations are under development
4. Gas Fees: Transactions are executed through Relayer, gas fees are handled by the Relayer
