BasedApp: The First Noncustodial Visa Debit Card in Singapore
BasedApp bridges traditional banking and crypto with a wallet and the first non-custodial Visa debit card in Singapore. By tapping into Visa terminals, users can directly spend tokens stored in their BasedApp Wallet, transforming how crypto is used in daily life. More countries will be supported soon.
The BasedApp Ecosystem: Wallet & Card
The BasedApp Wallet is a secure, non-custodial crypto wallet that goes beyond storage. It enables:
Social logins via Google and Email for secure wallet access
1-click transactions with batched signings
Instant token transfers to friends
Gasless Transactions: Powered by Gelato Relay, removing the need for native gas tokens
The BasedApp Card lets users spend directly from their wallets at any Visa merchant, eliminating intermediaries. Users simply top up their card from the wallet and begin spending.
Account Abstraction & Gelato Relay in BasedApp
BasedApp is built on Safe Core, an advanced account abstraction framework that simplifies complex interactions. With login via email or Google and 1-click transactions, onboarding becomes as smooth as Web2.
By integrating the Safe Core AA SDK Relay Kit powered by Gelato Relay, BasedApp enables gasless transactions. Developers gain secure, efficient validation infrastructure while users enjoy effortless, fee-free blockchain interactions.
Comparing Payment Flows
Traditional Card Payment Flow

Steps:
User initiates payment
Merchant submits transaction
Acquirer forwards request
Card networks facilitate messaging
Issuer approves or declines transaction
BasedApp Card Payment Flow

Steps:
User pays with BasedApp card linked to their wallet
Merchant POS requests payment
Acquirer forwards details to Visa
Visa routes to Fazz Financial Group (issuer for BasedApp)
Fazz ensures regulatory and banking compliance
BasedApp checks user vault contract on Polygon for sufficient funds
Vault contract confirms balance in real-time
Gelato Relay covers gas fees and processes the on-chain payment gaslessly
Once verified, approval flows back through Fazz, Visa, and the acquirer to the merchant. Settlement occurs in fiat, while Gelato Relay handles the crypto side, moving stablecoins from the vault contract to BasedApp.
The result: users pay with crypto, merchants receive fiat—seamlessly bridging traditional and decentralized finance.
Conclusion
BasedApp is redefining crypto payments with a wallet and Visa card backed by Gelato Relay. By eliminating blockchain complexity and gas fees, it sets a new standard for mainstream crypto adoption and paves the way for the democratization of DeFi.
