Justin Sun: Crypto Cards Will Put Stablecoins at Checkout

Justin Sun, founder of Tron, wrote on X that crypto cards will embed stablecoins into everyday merchant payments, noting stablecoins processed about $33 trillion in 2025 and that Tron holds more USDT in circulation than other blockchains.

Industry data show the stablecoin market opened 2026 with roughly $310 billion in total supply. Transaction volumes expanded in 2025 across crypto-native networks and traditional payment rails.

Much of the $33 trillion reflected trading and liquidity flows rather than consumer spending. Still, consumer-facing crypto card transactions grew in 2025 to levels that rivaled direct peer-to-peer stablecoin transfers, moving more on-chain value into merchant and cross-border payments.

Major card networks added support for stablecoins. Mastercard enabled stablecoin acceptance at more than 150 million merchants through a partnership with Moonpay. Visa expanded stablecoin settlement to nine networks and supports over 130 card programs across more than 50 countries. Those programs connect stablecoin settlement rails to existing merchant acceptance.

On-chain data show Tron holds a larger share of USDT than other blockchains. Tron developers have rolled out gasless transaction options to reduce frictions for users moving stablecoins and are testing payments driven by agentic artificial intelligence.

In a post on X, Sun described crypto cards as the ‘next evolution’ for digital assets and linked Tron’s existing stablecoin traffic and payment-focused features to broader merchant use. Industry participants continue to deploy card programs and settlement rails that route stablecoins to point-of-sale networks.
