Overview: Zero Hash Liquidity Service

Zero Hash Liquidity Service (ZHLS)

ZHLS provides in-house liquidity to connected platforms. The product is convenient and API lift is minimal.

The liquidity pairs we support for Crypto-to-Fiat and Crypto-to-Crypto vary by environment. Please contact us if you have any questions.

Price Precision - The maximum number of decimals in the quote price returned.
Quantity Precision - The maximum number of decimals that can be submitted for quote retrieval. Any quantity submitted with higher precision will be rounded down.

Note: If the 'total' field is used instead of 'quantity' when retrieving quotes you will get price precision to 16 decimal places. The quantity returned will have the precision detailed below.

Any ending zeros will be dropped from the price and quantity precision.

The supported fiat currencies are USD, CAD, EUR and GBP. 

The supported fiat currencies must be in the account prior to exchange to prevent delayed settlement.

It's possible that some asset configurations must be made on a per-participant basis, so please communicate with a Zero Hash representative if you are getting a rejection message.

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 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

  • 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

  • Request examples with parameters (you must enter either a quantity or total figure):

Quantity

"side":"buy",
"underlying":"BTC",
"quoted_currency":"USD",
"quantity": 1

 

Total

"side":"buy",
"underlying":"BTC",
"quoted_currency":"USD",
"total": 65000

 

2. Receive response

  • Response example (applicable to both Quantity and Total example above)
{

"message": {
"request_id": "ce819fe8-b1d7-43bb-961c-e09ede0988d3",
"participant_code": "PLAT01",
"quoted_currency": "USD",
"side": "buy",

"account_group": "00SCXM",
"account_label": "general",
"underlying": "BTC"
}
}

 

3. Execute order

  • Send a POST /liquidity/execute request using the quote_id from the response in step 2.
  • The credit check is done on the PLAT01's USD balance, 00SCXM account group.
  • You will have 5 seconds before the quote expires.
  • Execution example:
{
“quote_id”: “5cd07738b861c31e3bd61467BTC1Buy1568311644602"
}

When your trade has completed, the asset that the platform purchased will be auto-allocated to the Zero Hash Liquidity Services (00SCXM) platform, or account group.
