The Ekiden API provides REST endpoints and WebSocket streams for interacting with both the off-chain central limit order book (CLOB), where matching and execution take place, and the on-chain settlement layer on Canton. While most interactions happen off-chain, some workflows also involve on-chain actions on Canton. All trading actions require digital signature authentication. Orders are matched off-chain for speed, but are cryptographically verified and settled on-chain using Merkle proofs.

​
Connectivity & Integration

Ekiden’s API is built for low-latency, high-throughput trading infrastructure:
  • REST endpoints handle order execution, cancellation, market data, and account management.
  • WebSocket streams provide real-time updates, including trade events, order book changes, and fills.

​
TypeScript SDK

The official TypeScript SDK simplifies integration with the Ekiden API by providing typed REST and WebSocket clients, authentication helpers, and ready-to-use examples for Node.js and browser applications.
  • ekiden-ts-sdk — Official TypeScript SDK for the Ekiden API.
