How it works

Scan. Pay. Done.

1

User scans QR

A user on your platform scans any local merchant QR code — PromptPay, VietQR, KHQR, LaoQR — through your app via Mekong's API.

2

We bridge the payment

Mekong debits the user's linked card, bank account, or stablecoin wallet. Converts currency instantly. Routes through fully regulated local rails.

3

Merchant gets paid

The merchant receives funds in their local currency, instantly. From their side, it looks like a normal domestic QR payment. Zero friction.

The API

Why us

We spent years on the ground so you don't have to.

Accessing domestic payment rails in Southeast Asia means navigating central banks, local banking partnerships, and regulatory frameworks across multiple jurisdictions. We've already done all of it — the relationships, the infrastructure, the compliance. You just plug in.

Full regulatory compliance

Built from the ground up to meet international KYC/AML standards across every market we operate in.

Direct banking partnerships

Not a workaround. Not a grey area. Direct integrations with local banking infrastructure and national payment networks.

Multi-jurisdiction, one integration

We hold the relationships across multiple countries so your single API call routes through the right rails automatically.

The vision

Southeast Asia is the starting point.

Every country has domestic QR rails — Pix in Brazil, UPI in India, M-Pesa in Kenya. None of them talk to each other. We're building the universal API to connect all of them.

Now Mekong corridor
Next Wider ASEAN
Then Global

We're just getting started.

Mekong is building the payment infrastructure layer that connects local QR rails globally. Register your interest to be among the first to integrate.
