IDEX Connector

About IDEX

IDEX is an Ethereum based decentralized smart contract exchange that allows for real-time trading. By combining aspects of centralized exchanges, it is able to enable real-time trading while maintaining blockchain settlement security protocols.

Using the Connector

Because IDEX is a decentralized exchange, you will need an independent cryptocurrency wallet and an ethereum node in order to use Hummingbot. See below for information on how to create these:


IDEX requires an API key authentication to access API endpoints required for Hummingbot use.

Enter your IDEX API key >>>

Private keys and API keys are stored locally for the operation of the Hummingbot client only. At no point will private or API keys be shared to CoinAlpha or be used in any way other than to authorize transactions required for the operation of Hummingbot.
