Stablecoin Cards Enable Continuous Off Ramping
Why Kraken acquired Reap for $600M
Stablecoin cards matter because they turn stablecoins from an occasional treasury rail into an everyday spending rail. Instead of wiring funds out of crypto, waiting for a bank balance to update, and then spending, a business can hold USDC on chain, post it as collateral, swipe a card for software, travel, or taxis, and settle the bill later. That makes off ramping continuous, invisible, and frequent, which is exactly why card volume can ramp much faster than bank transfer volume.

Rain built this around a very concrete workflow. A customer deposits stablecoins into a smart contract it controls, Rain extends a matching credit line, merchants get paid in fiat over Visa or Mastercard, and the customer repays with tokens, ACH, wire, or collateral already posted. That removes the need to pre convert treasury into bank deposits before every expense.

The strongest early use case was not speculative consumer spending, it was crypto native businesses with real operating bills. Rain found the biggest dollar volume came from normal company purchases like Zoom, G Suite, Amazon, airfare, and conferences, while the highest transaction counts were everyday in person purchases. That pattern is what real product market fit looks like, repeated business spend, not one off crypto novelty.

This is also why Kraken wanted Reap. Kraken already has liquidity, custody, and on off ramp demand from its exchange. Reap adds the card and spend orchestration layer for businesses, while Kraken brings the stablecoin inventory and conversion engine underneath. Together they can capture more of the payment loop, from holding dollars on chain, to spending them through cards, to settling back into fiat or stablecoins.
The next phase is stablecoin cards becoming default financial plumbing for globally distributed businesses, then getting bundled into broader fintech stacks. As cards, accounts, payouts, custody, and exchange liquidity converge, the winner will be the platform that makes stablecoin money usable everywhere a normal business already spends, without forcing users to think about crypto at all.
