Digital Public Infrastructure

The shared rails a digital economy runs on.

Digital public infrastructure (DPI) is the small set of systems that every other digital service depends on: a way to prove who you are, a way to pay anyone, and a way to share data safely. Built once, openly, it lets governments, banks and fintechs serve a whole population instead of a lucky few.

Three pillars

Identity, payments, data exchange.

Each pillar is useful alone. Together they compound: an ID that can open an account, an account that can receive a payment instantly, and a consented record that proves eligibility without a queue. We go deepest on payments, and design identity and data exchange so they connect to it cleanly.

Pillar 01

Payments

Inclusive instant payment systems: interoperable rails every bank, wallet and agent can reach.

Pillar 02

Digital identity

Foundational ID that lets people prove who they are, and lets services onboard them remotely.

Pillar 03

Data exchange

Secure, consented exchange between registries and services, so citizens stop being the courier.

How the layers fit

One stack, five layers.

DPI works as a stack. Open standards at the bottom keep it replaceable; services at the top are where people feel it. Our work sits in the middle: we build payment rails and the tools that keep them running, and we integrate identity and data exchange so the layers work as one.

  1. 01

    Open standards and digital public goods

    ISO 20022, open APIs, and open-source platforms such as Mojaloop, MOSIP and X-Road. The layer that keeps a country free to change vendors.
  2. 02

    Digital identity

    A foundational ID that anyone can use to prove who they are, and that services can verify remotely.
  3. 03

    Payment rails

    An instant, interoperable payment system that every bank, wallet and agent can join on fair terms.
  4. 04

    Data exchange

    Consented, secure flows between registries and services, so data moves instead of people.
  5. 05

    Services

    What citizens actually see: social transfers, merchant payments, account opening, public services.
Principles

How we build it.

Open by default

We build on digital public goods and open standards, so the country owns the stack and can change suppliers without starting over.

Interoperable from day one

Every participant connects through the same published interfaces. No bilateral integrations, no closed loops.

Inclusive by design

Feature phones, agents and low-connectivity areas are the design target, not an afterthought added after launch.

Governed by its users

Scheme rules, participation tiers and oversight are designed alongside the technology, with the institutions that will run it.

Secure and sovereign

On-premise or in-country cloud, an operating ISMS, and data that stays where the law says it must.
We don't build systems for partners. We build them with partners.
