Builder Program

Build applications that route orders through Polymarket

A builder is a person, group, or organization that routes orders from users to Polymarket. If you've created a platform that allows users to trade on Polymarket through your system, this program is for you.

Program Benefits

All onchain operations are gas-free through our relayer Get credit for orders and compete for grants on the Builder Leaderboard

What You Get

Benefit	Description
Relayer Access	Gas-free wallet deployment, approvals, order execution and CTF operations
Volume Tracking	All orders attributed to your builder profile
Leaderboard	Public visibility on builders.polymarket.com
Support	Telegram channel and engineering support (Verified+)

EOA wallets do not have relayer access. Users trading directly from an EOA pay their own gas fees.

How It Works

User places an order through your application. Your app adds your `builderCode` to the order struct. Order is submitted to Polymarket's CLOB — the builder code is serialized onchain as part of the signed order. Polymarket matches the order and covers gas fees for onchain operations. Volume is credited to your builder account for every matched trade where your code is attached.

Getting Started

Go to [polymarket.com/settings?tab=builder](https://polymarket.com/settings?tab=builder) and copy your builder code. Pass `builderCode` on every order you submit — see [Order Attribution](/trading/orders/attribution). Use the Relayer Client for gas-free wallet deployment and onchain operations. Monitor your volume on the [Builder Leaderboard](https://builders.polymarket.com). Bridging user funds in or out via the Bridge API? Also pass your code via the optional `X-Builder-Code` header on [`/deposit`](/trading/bridge/deposit) and [`/withdraw`](/trading/bridge/withdraw) so bridge traffic is attributed to your integration.
