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 from discovery through status tracking.

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
