Integration Flows

Choose the integration flow that best fits your use case:

Direct Swaps

Best for: Cross-chain swaps and controlled rates

  • Swap a predefined number of pairs (belonging to the same or different chains)
  • The swap is as easy as a “send” transaction
  • Get multiple rates or quotes for a pair
V3 endpoint map: discover assets and pairs, get rates or quotes, create an order, then monitor its status
The endpoint families below follow this path. Resources provide network, terminology, and version context alongside it.

Endpoints

  • Assets - Get information about supported assets
  • Pairs - Get available trading pairs and limits
  • Rates - Get exchange rates for pairs
  • Quotes - Get quotes for swaps
  • Orders - Create and manage orders
