Monthly spending on cryptocurrency-linked cards reached US$600 million in March 2026, more than tripling the US$187 million recorded the previous year – a 211% year-over-year increase that indicates structural rather than cyclical adoption across point-of-sale payment infrastructure.
Cumulative card volume during the period reached $6.5 billion across 21.4 million transactions, with Visa processing $581.8 million, or approximately 97% of the March total. The numbers point to the emergence of cryptocurrency debit and prepaid cards as a meaningful payment channel in the real world, not just a retail novelty.
The structural significance of this $600 million figure lies as much in its absolute scope as in what it represents architecturally: a reduction in the frictional cost of converting onchain balances into daily purchasing power, without routing through the cumbersome out-of-the-way infrastructure – token withdrawals, bank transfers, and settlement delays – that has historically made spending on cryptocurrencies impractical at the point of sale.

We believe the sustained growth rate, which has averaged upward over six consecutive quarters, reflects a user base that has graduated from speculative retention to an active payment instrument.

Crypto Card Size Mechanics: What $600 Million Per Month Represents Structurally
The mechanism works as follows: Crypto-linked debit and prepaid cards allow users to denominate balances in stablecoins or other digital assets, which are then converted at the point of sale through the rails of the card network – in the first place – into local fiat currency before settlement with the merchant.
The user experiences a standard card transaction; The leveling layer is entirely on the chain. This architecture eliminates the outright derailment step while maintaining compatibility with existing merchant acceptance infrastructure, which is why Visa’s 97% share of trading volume in March is less a story of market concentration than a reflection of how deeply Visa’s network has been integrated into global point-of-sale acceptance.
TRON accounted for 35% of March’s payment volume via blockchain, with BNB Chain accounting for 15% — a distribution that reflects the economics of fees that drive issuer and user choices rather than any ideological preference for those networks over Ethereum.

Southeast Asia accounted for nearly 60% of the global stablecoin payment volume in this period, and domestic card issuance grew 83-fold between 2024 and 2025, according to the context of the research compiled alongside it.
This geographic focus is important to explain the volume figure: A significant portion of the $600 million monthly total reflects users in markets where crypto cards serve not as a comfort layer on top of traditional banking but as a primary financial access mechanism.
Emerging issuers — including KAST, Tria, and Solana-based Pengu Card, which enables USDC and USDT spending at an estimated 150 million merchants globally — have expanded the competitive playing field beyond previous market leaders.
US merchant adoption reached 39% during this period, indicating that the local market is absorbing cryptocurrency card infrastructure at a pace not seen in previous years. The monthly figure of $600 million, combined with the cumulative amount of $6.5 billion in transaction history, represents a payments channel with enough transaction depth to attract serious issuers and invest in the networks – a threshold that POS crypto spending has never crossed before.
