Introduction to ZHLS

Similar to how “Banking as a Service” enabled FinTechs to focus on building products, Zero Hash provides the infrastructure to clear and settle digital assets in a completely automated and regulated way. Zero Hash provides liquidity as a service, providing a “one stop shop” for settlement and liquidity services through API that enables best execution and customization.

This FAQ outlines how to incorporate ZHLS execution streamline to the Zero Hash settlement workflow.

Benefits of Using the ZHLS

Zero Hash’s liquidity provides clients the ability to source liquidity across assets through a couple of lines of code. This provides a building block to innovate and develop products within the digital asset eco-system.

In addition, since liquidity is sourced directly from Zero hash as opposed to an external party, settlement occurs instantaneously improving speed and cost since there are no network fees or on-chain confirms.

Technology

General Guidelines

All quotes expire after 5 seconds.
Certain configurations need to be made by the Zero Hash Client Services team. Please reach out to support@seedcx.com or via a shared Slack or Telegram channel to enquire about using the product.
We currently support 3 different models (See below sections for details). Work directly with a Zero Hash representative to learn which suits your platform best:

Model	Platform a counterparty to trades?	Credit Check	Notes
Standard	Yes	Platform's Account	Preferred if the platform is indifferent to taking on a crypto side of the trade
Novated Deferred	No	Float Account	Preferred if the platform does not wish to touch crypto in any trade Cash leg is settled on T+X
Platform Direct	No	Platform Customer Account	Useful for platforms that wish to ledger the customer's fiat balance at Zero Hash Platforms can show a "Available" versus "Pending" balance on their front end
