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.

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

​
How It Works

1

User Places Order

User places an order through your application.
2

Attach Builder Code

Your app adds your builderCode to the order struct.
3

Submit to CLOB

Order is submitted to Polymarket’s CLOB — the builder code is serialized onchain as part of the signed order.
4

Trade Execution

Polymarket matches the order and covers gas fees for onchain operations.
5

Volume Attribution

Volume is credited to your builder account for every matched trade where your code is attached.

​
Getting Started

1

Create Builder Profile

Go to polymarket.com/settings?tab=builder and copy your builder code.
2

Attach Your Builder Code

Pass builderCode on every order you submit — see Order Attribution.
3

Enable Gasless Transactions

Use the Relayer Client for gas-free wallet deployment and onchain operations.
4
