OpenOcean DCA API Integration Guide

OpenOcean provides an API interface for DCA (Dollar-Cost Averaging) trading, enabling developers to implement automated swaps. This guide will introduce how to use this feature's API.

Currently we only support the Base/Sonic chain, and will expand to other EVM chains in the near future. Below are the OpenOcean DCA contract addresses :

DCA V1 contract address(Base): 0x7F727EB80183D5dE9bdd11dF6b8C402bab1DF147

DCA V2 contract address(Base/Sonic): 0x6cBB2598881940D08d5Ea3fA8F557E02996e1031 *If you're the first time integrating our DCA, please use the V2 contract address. V1 will be deprecated soon.

DCA Overview

The DCA feature allows users to automatically invest fixed amounts at regular intervals on the OpenOcean.

Important Notes

a) All amounts must include token decimals

b) Use status parameters for efficient filtering

c) Verify minimum amounts before order creation

d) Monitor order execution progress
