OpenDEX prediction infrastructure
Backend services for branded apps with Polymarket account and order workflows
OpenDEX offers backend services for teams building trading applications and names Polymarket among its integrations. The platform combines account and wallet workflows, execution state, live events and operator reporting behind APIs. Its own FAQ says custody, execution and compliance responsibilities must be agreed before a production launch. This profile therefore describes the documented integration surface without treating every broader crypto feature as an implemented prediction capability.[1]

Overview
- Trading mode
- Execution and automation infrastructure is advertised; the integrating application determines user authority and workflow. The homepage does not establish that all generic bot features operate on Polymarket.[1]
- Funding and prerequisites
- An eligible developer organization and API access, plus agreed responsibilities for the actual account and execution model. No API key was created and no financial endpoint was called.[1]
What it offers
Application backend
The provider describes supplying user accounts, wallet workflows and execution state so an integrator can build its own product interface.[1]
Page data and live updates
Screen-oriented API responses are paired with sockets that update account and position state, with snapshot reload after disconnect.[1]
Execution visibility
The platform describes order, position, fee-estimate and transaction-error records rather than only a submitted-request response.[1]
Operator reporting
An organization dashboard brings together users, keys, fees and operational reporting.[1]
Controlled agent integration
Structured endpoints can support external agents, while the provider says financial actions still require product-level permissions, limits and monitoring.[1]

Getting started
- What you need first
- An eligible developer organization and API access, plus agreed responsibilities for the actual account and execution model. No API key was created and no financial endpoint was called.[1]
Safety and terms
- Custody and keys
- The provider advertises managed-wallet workflows but says final agreements must define custody, security and execution responsibilities. A specific Polymarket key-storage or withdrawal authority model was not established.[1]
- Access conditions
- The provider distinguishes a prototype/free tier from production and enterprise agreements. Public product wording alone does not establish a complete geographic or financial-authorization scope.[1]
