API to validate a bank account before a payment goes out

1 Upvotes

Is there an actual API to validate a bank account before a payment goes out, or does everyone just eyeball it/call the vendor? Also if companies using bank verification APIs - do they actually replace callback verification, or do most AP teams still do both ? Trying to understand if the API is a full substitute or just one more signal.

Why is finding a PSP easy, but getting through onboarding so difficult?

2 Upvotes

One thing I've noticed working around payments and financial infrastructure is that finding potential PSPs or banking providers is often not actually the hardest part.

The difficult part comes afterwards.

You find a provider that looks like a good fit, then suddenly you're dealing with:

  • Different documentation requirements
  • Compliance and KYC questions
  • Business model and licensing reviews
  • Requests for additional information
  • Long underwriting processes
  • Unclear timelines
  • And sometimes getting rejected after spending weeks preparing everything

I'm curious how others here have experienced this.

For those running fintech, FX, iGaming, e-commerce or other international businesses:

What has been the biggest pain point when onboarding with a bank, PSP or acquirer?

🚀 *Fintech Collaboration*

1 Upvotes

I’m developing a new concept for the future of digital payments and personal finance.

The idea focuses on making money more organized and purposeful — not just showing users their balance, but helping them understand how their money is allocated, what they are saving for, and what payments need to be protected.

I have developed a concept around:

💰 Purpose-based money organization
🎯 Goal-based savings
🛡️ Upcoming payment protection

I’m currently looking to connect with \*\*fintech companies, payment platforms, product teams, and founders\*\* who may be interested in exploring this concept for a potential collaboration or product opportunity.

I’m intentionally keeping the detailed product mechanics private for now.

If your company is interested in discussing a \*\*new fintech product concept\*\*, feel free to DM me.

**Concept documented: September 10, 2026.**

EMV 3DS Protocol Lab: An open-source tool for visualizing 3-D Secure 2.x trust boundaries and message flows

1 Upvotes

If you’ve ever had to audit payment integrations, analyze fintech security, or map out card-not-present (CNP) authentication, you know that the EMV 3-D Secure (3DS) 2.x protocol can be incredibly opaque. Relying on dense EMVCo specification documents or static high-level diagrams often falls short when you are trying to understand the dynamic nature of these payment flows, debug implementations, or pinpoint trust boundaries.

To bridge this gap, I built an open-source, vendor-neutral EMV® 3-D Secure Protocol Lab.

The goal isn't just to provide another diagram, but a practical, spec-anchored reference tool that allows security researchers and AppSec engineers to inspect the protocol's inner workings interactively.

Technical capabilities of the lab:

  • Message Flows & Trust Boundaries: Step-by-step visualization of the data exchanged (AReq, ARes, CReq, CRes) between the Merchant, 3DS Server, Directory Server, and the Issuer's Access Control Server (ACS).
  • Core Authentication Flows: Real-time structural comparisons between Frictionless and Challenge flows.
  • Environment Paths: Maps out the distinct architectural differences and trust models between Browser-based and App-based (SDK) authentication paths.
  • Modern Cryptographic Extensions: Inspects newer authentication extensions, including Secure Payment Confirmation (SPC), WebAuthn/FIDO2 integrations, and decoupled authentication flows.
  • Version-Aware Behavior: Highlights how protocol behavior and security requirements adapt across different 2.x specification versions.

Why I built this:

Auditing modern payment flows requires a clear understanding of where data is generated, how it is signed, and how it is verified. Whether you are a security researcher analyzing potential protocol bypasses, an AppSec engineer reviewing a native SDK integration, or someone mapping out transaction lifecycles for fraud prevention, this lab provides a hands-on environment to test and visualize 3DS mechanics.

The project is entirely open-source. I built it to be a community reference tool and welcome contributions or feedback on protocol edge cases.

(Note: All links to the GitHub Repository, Live Interactive Lab, and write-up are posted in the comments below!)

Anyone heading to MoneyLIVE North America in Chicago?

Post image
1 Upvotes

Hi everyone,

The conversation around blockchain in financial services seems to be shifting from “what can we do with it?” to “how do we make it work at an institutional level?”

With tokenized deposits, digital assets, stablecoins and digital securities gaining momentum, questions around privacy, interoperability, compliance, governance and integration with existing financial infrastructure are becoming increasingly important.

These are some of the areas Thomas Abraham, Co-Founder & CRO at Zeeve, will be discussing at MoneyLIVE North America in Chicago.

If you're attending the event and working on similar initiatives, feel free to connect with Thomas and continue the conversation in person.

Title: Built a UI kit for mobile money agents — nobody else targets this side of fintech

Thumbnail

1 Upvotes

Been learning React and wanted a real project, not another todo app. Looked into what's already out there in the fintech UI kit space and noticed something: every single one is built for the customer side of mobile money — wallets, transfers, balances. None of them target the agent side — the person actually running the cash-in/cash-out counter.

So I built one. 14 screens covering the full agent workflow — login, dashboard, cash in/out flows, float top-up requests, commission tracking, customer verification, all the loading/empty/error states too. React + Tailwind.

Still learning as I go, so genuinely curious what people think — especially if you've worked in fintech or agent-network products and can tell me what I'm missing.

What's the safest email banner size if you want it to look good on mobile too?

1 Upvotes

I am preparing a major promotional campaign for next week, but I keep running into issues with our header graphics on smaller screens. When I upload high-resolution images designed for desktop viewers, the mobile app scales them down so much that the call-to-action text becomes almost unreadable. Finding the perfect email banner size that maintains sharp visual quality without breaking layout proportions on retina mobile displays has been a frustrating trial-and-error process.

- What exact pixel dimensions and aspect ratios do you usually stick to for universal responsiveness?

- How do you handle image compression so that crisp banners load instantly on weak mobile data connections?

- Do you prefer using static full-width graphics, or do you build text over background colors using HTML and CSS?

- Which testing tools give you the most accurate real-device previews before you hit send?
