Stablecoins were supposed to kill the credit card companies. But, like much of the crypto economy, they have found a symbiotic relationship with their supposed victims. 

“We’re seeing [that] stablecoin-linked cards are in hyper-growth-mode,” Cuy Sheffield, Visa’s head of crypto, said on CNBC last month. “There are new issuers coming into our network, launching stablecoin-linked cards every week.”

The data supports his claim. Once a niche product for true believers, crypto cards have seen tremendous growth over the past year. In September 2025, crypto cards saw $265 million in payment volume, according to DefiLlama data. That figure has grown more than threefold — last month saw $894 million in crypto card payment volume.

September didn’t just set a record in payment volume. It also set records in the number of transactions as well as the number of transacting crypto addresses. 

Entrepreneurs follow opportunity. Card providers are also multiplying, and our latest Spotlight details a new tool that helps users sift through the various cards on offer: DefiLlama’s Card Compare.

If you want to transact in crypto, you have a daunting amount of research to conduct. Which cards are available in your region? What are their fees? What kind of rewards do they offer?

Once you’ve found the right card, you might want to know what its requirements are, or the kind of information you need to furnish in order to sign up. 

Card Compare collects all that information, and more, into one easy-to-scan dashboard. 

The tool has its origins in DefiLlama’s MiCA dashboard, released earlier this year. Its unexpected success suggested people weren’t just seeking information that could help them invest — they also wanted information that could help them choose between myriad crypto applications, according to Patrick Scott, DefiLlama’s chief revenue officer.

The Card Compare dashboard includes cards’ issuers, the regions in which they’re available, the cash back they offer, the annual fees they charge, their foreign exchange fees, and their requirements. It also tracks the perks that cards offer, such as airport lounge access; the ATM fees they charge; the cryptocurrencies they let users spend; their integrations with Apple and Google Pay; and spending limits. 

Take MetaMask. It offers two debit cards: a “default” card and a higher-tier “metal” card. Both are available in 45 countries and offer 1% cash back, according to the dashboard. But the latter also eliminates the default card’s 1% foreign-exchange fee, a perk that’s gated behind a $199 annual fee. 

The tool also notes the MetaMask cards belong to the Mastercard network, and details their daily spending limits and ATM withdrawal terms. 

Providers that want their card to stand out can become sponsors; their cards are featured above the dashboard, allowing providers to display the cards’ key features. Plasma, a featured provider, highlights its Platinum card’s 10% cashback on AI and flights and 4% cashback on all other purchases.

Don’t cry for me, Argentina’s bank

Earlier this week, Argentina's central bank denied any crypto integrations with banking platforms for the foreseeable future.

News like this hasn't stopped its citizens from using crypto. In 2024, 20% of Argentines, about 8.6 million people, used crypto. Further, 12.5% of them used it every month.

The peso has gone from about 377 to 1,535 per dollar at the official rate since December 2023, and stablecoins became the way to hold dollars onchain. Stablecoins made up 62% of Argentine crypto transactions between 2023 and 2024, against a global average of 45%. On peso-denominated exchanges, more than 85% of assets bought in 2024 and 2025 were stablecoins.

Take a look back at our State of Argentina report, in collaboration with Crecimiento, to learn more about crypto adoption across The Land of Silver.

Adding a network to a wallet takes a chain ID, an RPC URL, and a currency symbol. Chainlist keeps all three in one place and fills them in when you connect your wallet. During a rather inconvenient Infura outage in early 2022, DeFi users pointed to it as the place to find alternative endpoints.

It’s open source and maintained by DefiLlama, and developers can pull the full dataset through the API. Today it lists 2,982 chains: new, old, and dead. Pick one and Chainlist fills in your wallet’s network details.
