Independent Software Vendors (ISVs) provide the software experience for retail traders on Polymarket US. ISVs are not brokers and carry no broker registration. You integrate using the same workflow as Introducing Brokers — see Your Role for what that involves and the Integration Journey for the end-to-end build path.
Audience: business and onboarding leads. This page covers ISV eligibility and agreements. Developers can go straight to the Integration Journey.
