About 120,000 payment cards went dead almost at once at the end of July 2026, when Kulipa, a Paris startup that ran stablecoin card issuing behind the scenes for some 20 fintechs and crypto wallets, abruptly shut down. The company closed on July 29, citing solvency problems, less than four months after announcing a seed round.
Few consumers noticed, because Kulipa was never a consumer brand. Its failure still exposes a dependency the industry rarely discusses: behind every “crypto” card sits a chain of specialist providers, and one weak link can cut off tens of thousands of cardholders overnight.
Kulipa ran the invisible layer behind stablecoin cards
Kulipa sold card-issuing-as-a-service. Its customers were businesses that wanted to offer a card without building their own connection to the networks. Through a single API, it issued white-label Visa and Mastercard cards funded by stablecoins such as USDC and accepted at more than 150 million merchants in about 100 countries.
The infrastructure went live in February 2025 and signed up well-known names in crypto and fintech: the Solflare wallet, Ready (formerly Argent), Africa’s Flutterwave, nSave, and Privy. A team of about 20 people, working from Paris, London, New York, Buenos Aires and Lagos, covered the European Union, Argentina and Nigeria, with a US rollout under way. The API bundled three layers:
- Connection to the Visa and Mastercard networks and issuance of card numbers
- Real-time conversion between the stablecoin and the merchant’s currency
- Compliance and card lifecycle management
The shutdown came four months after a $6.2 million seed round
The timing made the fall all the more striking. In early April 2026, Kulipa announced a $6.2 million seed round co-led by Flourish Ventures and 1kx, with White Star Capital and Fabric Ventures also taking part, bringing its total funding to about $9.2 million. Less than four months later, on July 29, it shut down.
Self-custody kept user funds out of the wreck
Despite the abrupt shutdown, user funds were preserved in most cases, thanks to a design choice. Kulipa favored a self-custody model: the money stayed in the user’s own wallet and was debited only at the moment of payment, through a co-signer with limited rights. Kulipa held no customer balances.
That design made all the difference. An issuer that holds customer balances, as in a classic prepaid program, exposes that money to its own bankruptcy risk. An issuer that only triggers a debit from a self-custodied wallet cannot, by design, take the money down with it.
| Issuer holds the balance | Self-custody (Kulipa) | |
|---|---|---|
| Where the funds sit | In an account at the issuer | In the user’s own wallet |
| When the debit happens | In advance (prefunding) | At the moment of payment |
| If the issuer fails | Funds may be frozen | Funds safe, card inactive |
Every link in the issuing chain is a point of failure
Beyond Kulipa, the case shows that the stablecoin card boom rests on a handful of thinly capitalized infrastructure providers. A fintech that launches “its own” card nearly always relies on a program manager, a processor, and a BIN sponsor bank. If one of them fails, the card fails with it, however solid the wallet on the front end looks.
The stablecoin industry likes to present the card as its bridge to everyday payments. The warning is plain: the promise of settlement in digital assets holds only if the plumbing underneath is bankruptcy-proof too. By failing, Kulipa has at least shown what really protects cardholders.
