BUSINESS IMPLEMENTATION GUIDE
Crypto-Backed Debit-Cards
Offer your users the ability to spend their crypto assets in real time via physical or virtual debit cards, without relying on centralized custodians. Hybrid-Chain makes it easy to connect self-custody Hybrid-Vaults to merchant payment rails, automating token-to-fiat conversion at the moment of purchase.
By leveraging Hybrid-Chain’s abstraction layer and transaction routing, your users maintain full control of their funds while enjoying seamless usability. Crypto is converted just-in-time, transactions are confirmed within milliseconds, and detailed records are retained on-chain for full transparency and accounting.
