Net Delivery Obligation (NDO) Overview

Net Delivery Obligations (NDO) is a Zero Hash-specific term that we've coined to reference "amount owed". In other words, this is the net amount owed to settle all active and outstanding obligations. It is the summation of:

• NDO = (Payable + Collateral Payable Available) - (Collateral - Receivable)

For example, assume a participant has $100,000 USD in their Available account and $60,000 collateral for an open position. They owe $200k to fully close out the position. Their Net Delivery Obligation would equal:

• NDO = $200,000 + $0 - $100,000 - $60,000 - $0
• NDO = $40,000

Once the participant deposits $40,000, their position will fully settle.

Consuming the NDO over API

There are 2 ways you can do this:

1. GET /accounts/net_delivery_obligations
   1. This endpoint will provide all NDO's for your participant only
   2. The client has to make no calculations
   JSON

   {
     "message": [
       {
         "asset": "USD",
         "amount": "40000",
         "account_group": "ABC123",
         "account_label": "general"
       }
     ]
   }
   

2. GET /accounts
   1. A client can derive the NDO's for their participant + their customer
   2. The client has to make a simple calculation.
      1. (Payable + Collateral Payable Available) - (Collateral - Receivable)
