RTP Support for Platforms

Release Details

Release Date: October 17, 2025

Release Type

Informational, no action required from platforms

Summary

Platforms can now fund their various USD accounts for the following products, via the RTP (Real Time Payments) Network:

Product	Purpose
Buy/Sell	Fund a float account for subsequent customer buys
Payins	Fund a refund float account for subsequent shopper refunds
Payouts	Fund a float account for subsequent payout transactions
On and Off Ramp	Fund a float account for subsequent on ramp transactions
Remittances	Fund a float account for subsequent remittance transactions

How it works

When initiating an RTP transfer to fund your account with zerohash, please ensure the remittance information field (also known as "memo" or "remittance note") is populated with your unique platform_code, hyphonated with the word "FLOAT". For example, PLAT01-FLOAT (PLAT01 is a hypothetical participant_code for the Platform).

This ensures funds are correctly and automatically applied to your account. Please note that the very first deposit sent from a unique account and routing number combination will need to be manually credited to your account and mapped to your participant_code, however subsequent ones are automatically and immediately applied.

Note: Most banking portals or APIs label this field as:

"Memo"
"Message to Recipient"
"Remittance Info"
"Note"
"Addenda"

If you don’t see this field or are unsure where to enter this info, please contact your bank’s support team for help with RTP formatting.

Getting Started

zerohash supports RTP through select banking partners only. Please consult your zerohash representative to confirm that RTP is enabled for the specific bank account selected for your integration.

New tier for business customer submission

Release date

September 12th, 2025

Release Type:

Informational, no action required from platforms

Summary

zeroHash now allows approved Platforms to onboard business customers with reduced API field requirements, requiring fewer data points and less information than traditional full KYB onboarding.

NOTE: These entities are considered non-customers of zerohash, do not hold accounts with us or take ownership of the funds at any point in the flow. However, zerohash still needs basic information in order to carry out our own diligence requirements.

Your Platform must be approved by our Legal and Compliance department before using this new feature. Get in touch with your zerohash rep to begin this process, if interested.

Example POST /participants/entity/new request with reduced API field requirements:

{
    "platform_code": "PLAT01",
    "legal_name": "Freelancer Platform XYZ Inc.",
    "contact_number": "15553765432",

Ability to invalidate a JWT token

Release date

September 5th, 2025

Release Type:

Informational, no action required from platforms

Summary

A new API endpoint has been introduced, allowing Platforms to programmatically invalidate JWT tokens. JWT tokens are used to invoke our SDK's, for context.

This enhancement provides greater control over session management and improves overall security.

How to invalidate a JWT token

Make a request to our new endpoint: POST /revoke_auth_token
Pass a body like so:

{
  "token": "${jwt}"
}

The response will be a "204 no context" on successful revoking of the JWT token.

Account Funding: deposit expiration webhook

Release date

Aug 13th, 2025

Release Type:

Informational, no action required from platforms

Summary

Applicable to the Account Funding product, ZeroHash has added a new webhook event to notify your platform when an End Customer’s fund transaction does not complete successfully - that is, when no deposit or fiat conversion has occurred. This event serves as a clear signal that no balance updates or account changes should be made, helping prevent discrepancies and ensuring accurate account state management.

The webhook will fire 30 minutes after the JWT token is generated and no fund activity is detected.

Example payload (see reason field):

 	
{
  "participant_code": "XXC653",
  "fund_asset": "ETH",
  "quoted_currency": "USD",
  "source_address": "-",
  "deposit_address": "0x30E76aDa6a159D742a33Ec1aF6Bd58FeB666145E",
