Getting Started

​

Prerequisites

Before you begin, ensure you have the following:

• Treasury Prime Account: Sign up for a Developer Sandbox account to access API keys and testing environments.
• API Credentials: Obtain your API Key ID and API Secret Key from the Treasury Prime Developer Sandbox.
• Bank Partnership: Establish a relationship with a partner bank that offers IntraFi or R&T services through Treasury Prime.

​

Bank Enablement Steps

Prior to enrolling in Enhanced FDIC Insurance, a Due Diligence process on the fintech between the bank and sweeps provider is required. The enablement timeline may vary depending on the bank’s sweeps provider.

1. Ensure your bank or TP contract has been updated to enable Enhanced FDIC access. Your sponsor bank must have previously completed onboarding with their choice of Depository Network provider.
2. Ensure you’ve worked with your bank and/or the Depository Network directly (if needed) to execute any necessary agreements. Be aware that you may need to incorporate additional language into your end-user terms of service.
3. Your sponsor bank will complete some setup for your program with the Depository Network and Treasury Prime, like defining the deposit interest rate associated with your program to ensure your end users accrue the appropriate interest. Treasury Prime or your sponsor bank will notify you when those steps are completed
4. Once your program configuration is complete, you’re ready to begin API development

Frequently Asked Questions

​

If my end user withdraws funds that triggers a withdrawal from the depository network, are those funds subject to availability delays?

No, in the case of a depositor withdrawing funds from their account when some of those funds are in the depository network, the bank makes the funds available upon request from the customer.

​

Do balance details available via Treasury Prime’s API reflect deposits that sit in the Depository Network?

Yes, the ledger balance always shows the sum of funds that exist on the bank’s balance sheet directly + funds that may sit outside of the bank in IntraFI.

​

How does interest payout work when a fintech has an interest rate in ICS?

This may vary by Bank and IntraFi agreement. It is encouraged for Banks to work directly with IntraFi on this.

​

How do thresholds work?

When processing sweeps to IntraFi, we calculate the transaction amount (delta) based on the current balance of the account at the time the file is generated. The balance used for this calculation is pulled from the current_balance field of the account.

The formula used to determine the transaction value (delta) is:

delta = max((current_balance - threshold_balance - sweep_balance), -sweep_balance)

​

Example Calculation -

Day 1: Initial Deposit
Current Balance: $400,000 Threshold Balance:$250,000 Sweep Balance: $0

Calculation:

delta = max((400,000 - 250,000 - 0), -0)  
       = max(150,000, 0)  
       = 150,000

📌 Result: We sent a transaction of $150,000 to IntraFi.

Day 2: Balance Reduction
Current Balance: $200,000 Threshold Balance:$250,000 Sweep Balance: $150,000

Calculation:

delta = max((200,000 - 250,000 - 150,000), -150,000)  
       = max(-200,000, -150,000)  
       = -150,000

📌 Result: We sent a transaction of -$150,000 to IntraFi to bring the sweep balance back to$0
