What's New in Modern Treasury’s PSP: Faster Onboarding, Checks, and Broader Stablecoin Support
We've made Modern Treasury’s PSP easier to get started with and more powerful as you grow. Recent updates include faster onboarding, support for checks and ACH debits, simpler stablecoin transfers, and more flexibility between PSP and BYOB models, all designed to help teams move money with less friction.

Explore With AI
Over the past several weeks, we've continued to invest in making Modern Treasury’s PSP easier to adopt, more flexible to operate, and more capable across payment rails. Here's what's new.
More Flexibility Between PSP and BYOB Models
Flexibility and the ability to grow with us over time are critical. That’s why our customers can choose the operating model that fits their business today while preserving flexibility for the future.
We're making it easier to move between PSP and Bring Your Own Bank (BYOB) configurations - teams can expand into either model from a single implementation as their needs evolve.
Explore PSP in the Sandbox
We've upgraded the PSP sandbox to more closely mirror production. Customers who click "Start Building" enter a pre-configured environment with PSP account setup already in place, allowing them to explore workflows and begin testing immediately.
The sandbox can also be reset to its initial state after testing rounds, making it easier to evaluate PSP functionality and accelerate implementation.
Expanded Payment Coverage
We've continued to broaden support across payment rails.
Physical and Digital Checks
Customers can now originate and mail physical checks, including support for custom logos and attachment pages. Controls are built into the experience, including the ability to stop a check via API or directly in the Modern Treasury application.
Soon, customers can also issue digital checks, generating a check image that can be delivered electronically to recipients for immediate deposit and cashing.
Received ACH Debits
Payment Accounts can now be enabled to receive ACH debits, unlocking use cases such as bill payment and account funding.
Accounts remain protected by a default debit block unless explicitly enabled for incoming debits.
These capabilities are in active use and will continue to be refined.
Expanded Stablecoin Capabilities
Simpler On-Ramp and Off-Ramp
Moving value on and off stablecoin rails now takes a single API call. Customers can move funds directly between fiat and stablecoin rails for their end customers without standing up intermediary payment flows, reducing implementation complexity and operational overhead
A Fiat-Grade Stablecoin Experience
We've reworked the stablecoin experience, so it behaves like the rest of the platform. Balances are displayed in dollars rather than stablecoin denominations, non-significant decimals are hidden, and wallet addresses stay out of the way unless needed.
Managing stablecoin balances now feels consistent with managing every other account in Modern Treasury.
More Reliable Data and Account Management
Prior-Day Balances
Customers can now view historical closing and available balances, providing greater visibility for reconciliation and cash management workflows.
Update legal entities in place.
A new PATCH /legal_entities endpoint allows you to re-submit updated Legal Entity information in response to requests for more information or entity updates. Fixing a typo in an EIN or updating a registered address no longer means starting over.
Looking Ahead
Digital check support is on track for July.
We're also bringing Push-to-Card online in July. Push-to-Card is an instant payment rail that sends funds directly to a recipient's debit or prepaid card. It works for anyone with a card and removes the need for bank account and routing numbers, enabling faster disbursements to a much wider set of recipients.
We’ll also be building out features like Account Statements to make data management easier.
As always, we'll keep sharing updates as new functionality becomes available.
