Release Notes - Version 3.36.0
Release Date: 03/11/2026


Summary

In the 03/11/2026 release, we are introducing a new stage in the platform’s evolution, focused on:

  • External wallet monitoring

  • A new ledger type for end-user accounts

  • Improvements to the crypto transfers report

What's New

1. External Wallets

The platform now supports the management of external wallets, including:

  • Registration, transfer monitoring, querying, listing, and removal of external wallets

  • External wallet transfers now appear in:

    • Activity > Crypto Transfers

    • Transaction Details

    • Reports related to crypto transfers

  • Association of external wallets as deposit addresses for end customers, enabling automatic deposit identification

Important Notes

  • Monitoring only considers transactions captured from the date the wallet is registered onward.

  • Support is restricted to assets on the Ethereum and Bitcoin networks already supported by the platform.


2. Ledger Type for End-Customer Accounts

This release also introduces the concept of Ledger Type, allowing differentiation between end-customer users associated with Virtual Ledger and On-chain Ledger.

The new ledger type introduced enables the creation of end-customer accounts whose balance is 1:1 with the wallet balance on the blockchain.

This change is reflected in:

  • API integrations

  • The platform user experience, with the inclusion of this information on the user creation, view, edit, and filter screens (CaaS Manager > Users)

  • The Whitelabel experience for end customers associated with On-chain Ledger, with a view aligned to this operating model, including balance position and on-chain transaction context


3. Crypto Transfers

The Crypto Transfers report export has been expanded to include the following new fields at the end of the exported file:

  • fromAddress — transaction source address

  • toAddress — transaction destination address

  • fee — fee amount paid

  • feeCurrency — asset used to pay the fee

When this information is not available, the returned value will be N/A.

Integration Impact

External Wallets

New API capabilities have been made available to support the External Wallets lifecycle, including:

  • wallet registration

  • listing of registered wallets

  • wallet removal

  • transfer listing

In addition:

  • external wallet registration and status update events will now be reflected in the existing wallet webhook;

  • transfers identified on monitored external addresses will now be reflected in the transaction custody webhook.

There have been no structural changes to the existing webhooks.


Ledger Type for End-Customer Accounts

The ledger type attribute is now available in the user endpoints of CaaS Manager (Crypto as a Service) in the following operations:

  • Get User

  • Create User

In Create User, the parameter is optional.

When not informed, the system assumes virtual.

It will also be possible to define the value as on-chain.


Crypto Transfers

Clients consuming the Crypto Transfers report export should consider the inclusion of the new fields fromAddress, toAddress, fee, and feeCurrency at the end of the exported file.
