Base Calls for LatAm Builders to Drive Onchain Impact

**Tuyo**, a new money app built on Base, has introduced a payment card with an unusual twist: **every purchase you make might cost you nothing**. The concept is simple but intriguing - when you swipe the card, there's a chance your transaction will be free. The app markets this as "buy now, pay maybe," turning everyday purchases into a potential lottery. **Key features:** - Built on Base blockchain infrastructure - Payment card with randomized free transactions - Gamifies everyday spending The app represents another step in bringing crypto-native financial products into daily use, though questions remain about the economic model and how the "free" purchases are subsidized. No details have been released about the odds of receiving a free transaction or the mechanics behind the system.
