Polymarket Auto-Redeem Script in Python (The SDK Can’t Do This)

Polymarket Auto-Redeem Script in Python (The SDK Can’t Do This)

More

Descriptions:

The Robot Traders channel publishes a Python solution to a long-standing gap in the official Polymarket SDK: the absence of automatic position redemption. When a Polymarket prediction market resolves, winnings remain locked as shares until a user manually clicks “Redeem” — a minor annoyance for casual users but a material problem for automated trading bots, where unredeemed positions tie up portfolio capital. A GitHub issue requesting an official fix has accumulated 32 upvotes without resolution.

The video walks through a self-contained Python function that handles redemption directly at the blockchain layer, bypassing the SDK limitation. Because Polymarket uses two different smart contract architectures — one for binary (yes/no) markets and one for multi-outcome markets — the function detects market type and routes accordingly. The author also addresses a key edge case discovered during development: redeemed positions remain on-chain and would trigger redundant redemption attempts without an explicit filter, which the script includes.

A notable design decision is portability: all constants and credentials are defined inside the function rather than as module-level variables, so developers can copy the function directly into an existing trading bot without refactoring. The function requires builder API keys (obtained from Polymarket account settings) in addition to standard wallet credentials, and supports both email-linked accounts and external wallet connections. The author credits community members from a Discord server for collaborating on edge cases during the trial-and-error development phase, and invites further feedback if undiscovered conditions surface.
