Tuyo’s ‘buy now, pay maybe’ DeFi card turns everyday spending into a gamble

At a glance:

• Tuyo launches a DeFi Visa card on Coinbase’s Base chain with yield-earning features and a ‘buy now, pay maybe’ model.
• The card randomly waives transaction fees, with over 1,700 waived on launch day—no odds or transparency provided.
• Critics warn the model mimics gambling mechanics, exploiting behavioral psychology to drive engagement.

A new frontier in gamified finance

Tuyo has introduced a DeFi-powered Visa debit card that introduces a radical twist on everyday spending: “buy now, pay maybe.” Built on Coinbase’s Base blockchain and using USDC stablecoin, the card allows users to hold funds in self-custodied wallets and earn yields through integrated DeFi protocols. Standard transactions deduct from available balances, but a key feature enables Tuyo to waive select transaction fees at random—effectively offering free purchases with no user control or predictability.

The fintech product supports deposits and withdrawals across Ethereum, Arbitrum, Optimism, and Polygon. Fiat on-ramps and off-ramps are handled through regulated partners, with foreign exchange fees kept under 1%, plus standard network charges. While Tuyo describes the fee-waiver mechanism as an algorithm designed to enhance customer satisfaction—not as gambling—it does not publish any statistical data on how often transactions are waived. This opacity raises red flags among financial watchdogs and legal experts.

Critics decry engineered addiction

Critics argue that the unpredictability of the card’s core feature closely resembles gambling mechanics, exploiting psychological triggers similar to those found in casinos and video game loot boxes. Fintech attorney Ariel Givner described the model as “engineered addiction” on social media, suggesting the waived transactions—1,700 on launch day—were a marketing ploy to generate buzz and FOMO. Most users, she noted, would likely never see a waived transaction again.

This criticism fits into a broader pattern of financial platforms adopting gamification to drive engagement. Examples include the Fold app, which offers bitcoin cashback and a spin-the-wheel bonus feature, and McDonald’s Monopoly promotions that turn food purchases into prize-based games. However, Tuyo’s model introduces a more direct financial incentive—actual monetary waivers—without offering users any insight into how or when they might benefit.

The rise of financial gamification

Gamified reward systems have long been part of consumer finance, but the trend has accelerated in the crypto and fintech sectors. Coinbase, once a simple platform for buying Bitcoin, now offers a wide array of speculative assets and prediction markets. Similarly, Robinhood has expanded from stock trading to crypto and event-based betting contracts. These platforms increasingly blur the line between investing and gambling.

This shift reflects not just a change in product design but also a deeper economic anxiety. As inflation pressures ease, structural inequalities persist. Federal Reserve data from Q3 2025 shows the top 1% of U.S. households control 31.7% of national wealth—a record high since tracking began in 1989. With $55 trillion in assets, that cohort holds as much as the bottom 90% combined. In such an environment, speculative financial tools may seem like the only way for average users to gain ground.

Gambling as economic survival tactic

The rise of gambling-like financial behavior echoes historical patterns seen in economies on the brink. Investment researcher Luke Gromen has drawn parallels between current trends and the Weimar Republic’s hyperinflation era, where gambling became a perceived necessity to protect and grow wealth. A 1975 book, When Money Dies, quotes from that period highlight how gambling on the stock exchange was seen as the only way to avoid financial ruin.

In 2025, the U.S. sports betting industry posted a record $16.96 billion in revenue, up 11% from the previous year, on a total betting handle of $166.94 billion. The Trump family’s net worth reportedly rose $1.4 billion due to crypto ventures, including DeFi platforms and memecoins, now accounting for 20% of their $6.8 billion fortune. These ventures have faced scrutiny for alleged conflicts of interest and opacity, further eroding trust in self-regulated crypto markets.

Tuyo and the casino economy

Tuyo’s card is the latest entrant in what critics call a “casino economy,” where speculative financial products and everyday spending tools are increasingly intertwined. While the company insists its model isn’t gambling, the lack of transparency about how often fees are waived undermines that claim. Users have no way to predict or influence the outcome, making each transaction a potential lottery ticket.

As more fintech companies adopt these psychological hooks, regulators may need to step in. Without oversight, products like Tuyo’s risk normalizing gambling behaviors and deepening financial inequality. The promise of yield and free transactions may attract users, but the long-term cost could be a more fragile and exploitative financial ecosystem.
