Polymarket Builder Program Guide

Polymarket Builder Program Guide is for people building analytics tools, routing interfaces, dashboards, or research workflows around prediction markets. The key idea is simple: if an application routes orders through Polymarket, Polymarket can attribute that routed volume to a builder code.

This page is educational. It explains builder concepts, attribution, fees, and product guardrails. It does not tell anyone to launch a bot, route orders, or trade a specific market.

Key concepts in plain English

• ▸Builder: A person, group, or organization that routes user orders to Polymarket through its own system.
• ▸Builder code: A public identifier attached to orders so routed volume can be attributed to a builder profile.
• ▸Order attribution: The process of tagging an order with a builder code for volume credit and monitoring.
• ▸Builder fee: A fee layer that builders may configure within enforced limits when orders route through their app.
• ▸Relayer access: Infrastructure that can support gas-free wallet deployment, approvals, order execution, and related operations for supported builder flows.

What Polymarket documents say

Polymarket describes builders as apps that let users trade on Polymarket through an external system. Documented benefits include relayer access, volume tracking, leaderboard visibility, and support at higher tiers. The docs also say builder fees are additive: they can stack on top of platform fees rather than replacing them.

Polymarket's order-attribution docs say the builder code is a bytes32 identifier tied to a builder profile and can be passed in the order struct. The code is public and appears onchain in the builder field of attributed orders.

Builder workflow at a high level

1. ▸Build a user-directed app or dashboard with clear research, source, and order-review steps.
2. ▸Obtain and manage a builder code according to Polymarket's current docs.
3. ▸Attach the builder code only to eligible flows you own and understand.
4. ▸Display costs clearly, including spreads, platform fees where applicable, and builder fees where applicable.
5. ▸Log routed volume, user-confirmed actions, errors, cancellations, and post-resolution outcomes.

Product guardrails builders should care about

A builder integration is not only an API exercise. It is a trust exercise. Users need to know what the tool does, what it does not do, what fees may apply, and where human confirmation is required.

A safer builder checklist includes:

User sees exact market question before action:
Resolution source visible:
Displayed price and executable bid/ask visible:
Spread and visible depth shown:
Fees and rebates explained:
Builder fee disclosed if used:
User-defined max-risk cap required:
Cancel path visible:
Order attribution logged:
Post-resolution review available:

Common mistakes

• ▸Treating builder attribution as a marketing badge instead of an operational responsibility.
• ▸Hiding fees, spreads, or routing assumptions from the user.
• ▸Using vague automation copy that sounds like the tool makes decisions for the user.
• ▸Forgetting that builder codes are public identifiers.
• ▸Measuring only routed volume instead of measuring support tickets, cancellations, slippage, stale data, and user review quality.

Bucko checklist

• ▸Builder code source and ownership documented.
• ▸Attribution is scoped only to the app's intended flows.
• ▸Fee language is clear and adjacent to action screens.
• ▸User-defined controls, daily caps, and kill switch rules are visible.
• ▸Every routed order has an audit trail.
• ▸Review dashboards separate education, monitoring, and user-authorized actions.

How Bucko fits

Bucko can help builders design the research and review layer around Polymarket: source checklists, market notes, order-review logs, fee notes, risk guardrails, audit trails, and post-resolution scorecards. The safe framing is user-directed research infrastructure, not a black-box profit machine.
