Liquid Connector

About Liquid

Liquid is a centralized exchange based in Tokyo, Japan launched by Quione in 2017. It also has offices in Singapore but is regulated and licensed by the Financial Services Agency of Japan. Over the past 12 months (as at May 2019) it has more than USD 50 billion in transactions on their exchanges.

Using the Connector

The connector is for Liquid based in Singapore (i.e. not for the local Japanese Liquid exchange). Because it is a centralized exchange, you will need to generate and provide your API key in order to trade using Hummingbot.

Enter your Liquid API key >>>
Enter your Liquid secret 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.

Copying and pasting into Hummingbot
