Stablecoins Powering Embedded Bank Payouts
Stablecoins and fintech infrastructure
This shows stablecoins crossing the line from crypto product to invisible back end for mainstream finance. Rain began as a corporate card company, but the demand now is from platforms, processors, and traditional financial firms that need to let users earn money in one place and spend it globally. In practice, they are buying a card and payout workflow, not a crypto product, with stablecoins simply replacing slower SWIFT, ACH, and prefunded treasury hops underneath.

Rain’s shift explains why traditional firms show up in the pipeline. The company built a card and expense product first, then expanded into infrastructure that lets other platforms issue payment instruments against stablecoin balances, including custodial and non-custodial flows.

The closest tradfi analogue is Lithic or modern issuer processing, but with blockchain as the settlement layer. A platform can give workers, sellers, or creators a card to spend earnings worldwide, while Rain monetizes through interchange and subscription fees much like Brex or Ramp.

This is happening because cross border money movement is where stablecoins are already better than legacy rails. Stablecoin payment volume rose from $26B in January 2020 to $1.4T in April 2024, driven by faster settlement, always on availability, and near zero transaction costs.
The next phase is distribution through existing financial brands. As banks, fintechs, and payment processors adopt stablecoin rails behind the scenes, companies like Rain move from selling a standalone card to powering embedded global payouts, treasury movement, and card issuing for much larger incumbents.
