A $6.2 million seed round wasn’t enough to keep Kulipa afloat. Barely four months after the Paris-based stablecoin card issuer closed a high-profile funding co-led by Flourish Ventures and 1kx, the company abruptly halted operations. The shutdown, first detailed in the original report , immediately rendered U cards unusable for an estimated twenty wallets and crypto firms—including Solflare and Ready. Users who had come to rely on the physical spending channels now face a void, even though their actual stablecoin balances remain untouched.
The roster of investors in that April round—White Star Capital and Fabric Ventures also participated—suggested serious backing. Yet the speed of the collapse has caught partners off guard. Solflare had previously told its community that the card-issuing partner had ceased operations because of solvency issues, a detail Kulipa itself has not publicly addressed. The gap between the glowing funding announcement and a quiet operational halt is unnervingly short.
Why User Funds Stayed Safe
Kulipa operated on a self-custody model. That means the company never held customer deposits. Funds were only pulled when a cardholder made a transaction, with the stablecoin converted and routed in real time. Because no balances sat on Kulipa’s own rails, the shutdown didn’t trap user money. This is a structural feature that more crypto card programs are adopting—partly to sidestep the custodial headaches that sank projects like the original Wavebridge—but it also means the service stops working the moment the issuer pulls the plug.
For end users, the protection is genuine. No funds are missing. But for the partner wallets and DeFi platforms that white-labeled Kulipa’s card infrastructure, the damage is reputational. Solflare and others now have to explain why a physical spending channel they promoted has gone dark. The operational reliability that users expect from a card program—especially one tied to stablecoins like USDC or USDT—depends on the issuer’s viability, and that viability just evaporated.
The Solvency Question and What It Means
Solflare’s mention of solvency issues shifts the narrative from a simple business failure to something potentially more troubling. A seed-stage startup typically isn’t carrying heavy debt, so insolvency this early hints at either a legal liability, a regulatory action that froze assets, or a cash burn rate that devoured the $6.2 million far faster than planned. Without audited financials or a statement from Kulipa’s leadership, the exact trigger remains unclear.
What is known is that the crypto card sector has seen a pattern of expensive but short-lived launches. The unit economics of issuing cards—partnering with legacy networks, managing compliance across jurisdictions, covering chargeback risks—drain capital fast. Even well-funded ventures like Kulipa can get caught between the licensing demands of Mastercard or Visa and the thin margins of crypto-native consumers. Other recent shifts in the space, including a U.S. legislative push that could reshape the stablecoin landscape, add yet more uncertainty. As we’ve noted in coverage of banks scrambling to influence pending crypto legislation , the regulatory ground is shifting precisely when card issuers need stability.
What Partners and Users Should Watch Next
The immediate effect is that around twenty wallet providers must scramble for alternative card-issuing partners or leave their users without a physical spending option. Solflare has not yet announced a replacement, and the gap underscores how concentrated the infrastructure layer can be. Projects that relied on Kulipa for a key consumer touchpoint are now looking at competitors such as crypto-native card platforms that have managed longer runways, though integration timelines are not trivial.
Meanwhile, the case adds a cautionary data point for allocators examining the stablecoin payments vertical. A $6.2 million raise from reputable funds does not guarantee survival—even in a bull cycle where stablecoin adoption numbers keep climbing. Some of that capital may have been earmarked for expansion plans that were, in retrospect, too ambitious. The failure also raises questions about whether self-custody card models can achieve enough transaction volume to cover their fixed costs before venture funding runs out.
For users, the shutdown is an inconvenience rather than a loss. But the real cost may show up in the willingness of wallet teams to push card products aggressively in the near term. Each high-profile closure makes the next partnership harder to sell, no matter how many safeguards are built into the architecture. The stablecoin card thesis isn’t broken, but Kulipa’s short flight is a reminder that even well-funded infrastructure bets can run out of oxygen fast.
