Unblock
Global payments and card issuing infrastructure powered by stablecoins.
Unblock is a Swiss-regulated fintech and Mastercard principal member enabling global payment and card issuing programs powered by stablecoins.
We provide infrastructure for fintechs, platforms, and merchants to launch and scale embedded financial products, including crypto-backed debit cards, cross-border payments, and on/off-ramp solutions.
Our platform bridges traditional finance and blockchain by combining regulated fiat rails with digital asset infrastructure. We leverage stablecoins as core settlement and treasury currencies, enabling faster, more transparent, and capital-efficient payment flows.
Key capabilities include:
- White-label Mastercard debit card issuing (crypto-backed and fiat)
- Stablecoin-based settlement for card programs and merchant payouts
- On/off-ramp infrastructure via global acquiring partners (including Worldpay)
- Safeguarded client funds with segregated accounts and wallets (Bank Frick + Fireblocks)
- Full compliance stack (KYC, AML, transaction monitoring, risk scoring)
Unblock supports high-growth fintechs, program managers, and global merchants - particularly those in complex or high-risk industries - providing compliant access to global payment rails.
Use Cases
Crypto-Backed Debit Cards
Stablecoins enable the real-time funding and settlement of card balances without relying on traditional banking delays, supporting reduced liquidity needs, improved authorization speeds, and global card usage backed by digital assets.
Cross-Border Payments
Stablecoins eliminate intermediaries from international transfers - reducing costs, FX friction, and settlement times - enabling near-instant cross-border transactions compared to traditional SWIFT rails.
On/Off-Ramp (Fiat ↔ Crypto)
Stablecoins provide a seamless bridge between fiat and crypto. Users can enter and exit the digital asset ecosystem efficiently with faster processing and improved transparency versus legacy methods.
Merchant Acquiring
Stablecoins allow merchants to accept card payments while settling in digital assets, improving cash flow, reducing chargeback exposure in some models, and enabling access to global customers without banking limitations.
