The Walled Wallet: How Iran Built a Complete Payments System Alone

Go back to that coat someone bought on Instagram in our first piece. The seller sent a card number, the buyer transferred the money, a screenshot sealed the deal. That small, almost invisible act, money moving instantly from one Iranian bank card to another, is the thing this article is about. Because behind it sits a complete national payment system that almost nobody outside the country understands, and that quietly powers everything from the corner bakery to the super-apps.

Most stories about Iran’s economy fixate on what it lacks: no global cards, no SWIFT for most banks, no foreign payment apps. All true. But focus only on the absence and you miss the much stranger fact. In the vacuum, Iran built its own everything, and it works at enormous scale.

The rails nobody abroad sees

Two pieces of infrastructure carry the load. The first is Shetab, the interbank card network launched in 2002 that connects every Iranian bank into a single switching system. The second is Shaparak, the payment switch that sits on top and routes electronic card payments across the country. Together they are the plumbing of Iranian money. Shaparak processes well over fifty billion transactions a year. Digital payment penetration sits around eighty-five percent, remarkable for a country under heavy sanctions.

The cultural fingerprint of all this is card-to-card transfer. Where an American reaches for Venmo or an Indian for UPI, an Iranian simply moves money card to card, instantly and cheaply, between any two accounts in the country. It is so universal that it became the default settlement layer for the entire informal economy, the Instagram shops, the freelancers, the landlords. The card number is the checkout.

Why it exists: necessity, not choice

None of this was a grand strategy. It was survival. As sanctions cut Iran off from Visa, Mastercard, SWIFT, and every Western fintech, the country had two options: have no modern payments at all, or build the whole stack itself. It chose to build. The result is one of the most complete sanctions-proof financial systems anywhere. Every layer that elsewhere is provided by a global player, the card network, the switch, the gateways, the wallets, the credit products, has a domestic equivalent in Iran, often a mature one.

The layer cake of players

Sit above the rails and you find a crowded, competitive market. By recent counts Iran has on the order of 275 active fintech companies, the overwhelming majority clustered in Tehran, and in 2022 the Central Bank opened a regulatory sandbox to let some of them test digital-banking ideas under supervision, a sign the state increasingly sees fintech as something to channel and grow, not merely to contain.

The payment gateways are the workhorses. ZarinPal became the default checkout for a huge swath of online merchants and small businesses. Alongside it sit bank-backed processors like Saman Electronic Payment and FANAP, the technology arm of Bank Ayandeh, plus peer-to-peer and invoicing tools like Bahamta and PayPing. And then the giants’ financial arms, which is where this connects to everything else: Digipay belongs to Digikala, SnappPay belongs to Snapp. The two super-ecosystems are not just fighting over commerce and rides; they are fighting to be your wallet. Fintech is the prize at the center of the super-app war.

The boom: buy now, pay later in an inflation economy

If one category is on fire, it is credit. Buy-now-pay-later arrived around 2020, with SnappPay the first and biggest mover, followed by Digipay and a wave of others like Tara. And it makes poignant sense. In an economy where the currency loses value by the week, the ability to buy now and pay later in money that will be worth less by the time you repay is not a luxury. It is a rational hedge. Inflation, which breaks so much, turned out to be rocket fuel for consumer credit.

Neobanks and the first real funding rounds

Iran even has a neobank scene. Blu, launched by Saman Bank in 2021, became the country’s first true digital bank and now holds the majority of the neobank market. Two more names come with something rare in Iran: disclosed funding. Emofid, a stock-trading and robo-advisory platform, reported around 1.5 million users and raised a Series A of roughly five million dollars in 2024. BimeBazar, an insurance comparison platform, serves around two million users. In a market where funding figures are almost never public, these are real, citeable rounds, and they signal that even now, with the wall at its highest, money is being raised and companies are being built. Independent analysts size the Iranian fintech market at roughly seven hundred million dollars today and project it past two and a half billion within the decade, and that is the trajectory under sanctions, not after them.

The whole landscape, in numbers

Step back and the scale of what Iran built in isolation is the real surprise. This is a full-spectrum financial sector with a credible player in nearly every category a developed market would have. The figures here are for the Iranian year 1403, roughly 2024 to 2025. The consumer front doors are the financial super-apps (Ap, Iva, Hamrah Card, Digipay), with something like forty-five to fifty million registered users and three thousand trillion toman of transactions a year. Underneath them, payment facilitators cleared roughly one hundred and eighty-nine million internet-purchase transactions. BNPL providers extended around seventy-five trillion toman of credit across some forty million transactions. Neobanks serve twenty to twenty-three million people. And then the categories outsiders never expect Iran to have at all: a wealthtech layer overseeing more than six hundred trillion toman in assets, an insurtech layer that sold sixteen trillion toman of policies, crowdfunding that raised nearly thirteen trillion toman, and a thriving gold-tech category (Milli, Goldika, Daric) with around ten million users that lets people buy and store physical gold by the gram. Remember the gold-buying surge from our e-commerce piece? This is the machinery underneath it. Two corners matter most for where this is heading: a cluster of API and open-finance aggregators (Finotech, Faraboom, Jibit) turning Iran’s banks into programmable infrastructure, and a set of cross-border payment bridges that have reached around two million users by solving the one thing the domestic system cannot do alone, letting Iranians pay foreign websites. (Crypto is the other elephant in the room, with an estimated fifteen million Iranians holding digital assets; it is too big and too sensitive to wave at here, so it gets its own careful piece.)

The benchmark: a walled UPI

India built UPI, a government-owned, fully interoperable real-time system that processed around one hundred and seventy billion transactions in a single year and is now extending across borders. China took the private route, with Alipay and WeChat Pay embedding payments inside super-apps. The United States and Europe still lean on the card networks and only recently built true instant-payment systems. Iran’s stack sits somewhere fascinating in that picture. Like UPI, it is a near-universal domestic system the whole population uses. Like China’s, it is increasingly wrapped inside super-apps. But unlike any of them, it is walled in. UPI is going global; Iran’s rails stop at the border. That is the one thing the system cannot do on its own: cross over. Which is why the most interesting recent development is a small crack in that wall. In late 2024, Iran’s Shetab network was connected to Russia’s MIR system. It is a modest, non-Western link, but it proves the appetite and the technical capability are there. The wall is not load-bearing. It is a policy, and policies change.

The catch, and the optimistic read

The honest caveats are real. Iran’s headline payment growth is wildly distorted by inflation, a recent month showed transaction value up nearly sixty percent year on year in nominal terms but only around six percent adjusted for inflation. The rial’s volatility makes every figure provisional, the central bank keeps a tight hand on the sector, and the grey zones, particularly crypto, we treat in their own piece. But step back and the frictions look, once again, like the moat. A payment system this complete, this widely used, and this independent of Western infrastructure is a strategic asset that took two decades to build and cannot be replicated quickly.

Iran has already done the hard part: a full-stack, high-penetration, sanctions-proof payments system, a competitive fintech market on top, and a credit and neobanking scene serving tens of millions, all while cut off from the global financial system. The single thing it lacks is cross-border connectivity, and that is precisely the piece a thaw would deliver. The countries that win in fintech are the ones with deep adoption and strong local rails already in place when the doors open. Iran has both. A market of more than ninety million people with eighty-five percent digital-payment penetration and no incumbent foreign networks to dislodge is, for anyone who can eventually reach it, one of the most attractive untapped fintech opportunities left on the map. That is the layer Tehran Index exists to make legible: not just that Iran has digital payments, but that it built, in isolation, a complete financial operating system, and the day it connects to the world will matter far more than most people realize.
