Stablecoin cards safer than banks and exchanges
Farooq Malik and Charles Naut, co-founders of Rain, on stablecoin-backed credit cards
The core advantage is that Rain turns stablecoin spending into a visible collateral workflow instead of a trust me deposit relationship. A customer keeps control of its own wallet and smart contract, posts USDC as collateral, receives a matching credit line, and can verify on chain that funds are segregated rather than pooled or lent out. That is why the product can feel safer than both an exchange account and a bank balance for crypto native treasury teams.

The practical difference from a bank is legal and operational. Rain is not taking a deposit and then deciding how to manage a pooled balance sheet. It issues a credit card against customer controlled collateral, so the customer can withdraw tokens, transfer contract ownership, or use posted collateral to repay the monthly statement.
-
The practical difference from a centralized exchange is inspection. On an exchange, a business usually sees an account balance on a dashboard and must trust the operator. Here, each customer has segregated collateral that can be checked on chain, which matters to teams still shaped by the failures of SVB, Silvergate, Signature, and exchange custody blowups.

This is also why Rain looks less like Brex or Ramp at the plumbing layer. Brex and Ramp use cards to pull companies into broader CFO software built around bank accounts, while Rain starts from the opposite problem, businesses with treasury already on chain that need cards, reimbursements, payroll, and accounting workflows without first moving money back into fiat banking.
The next step is for this model to fade into infrastructure. As more companies hold part of treasury in stablecoins and want to spend, reimburse, and pay vendors from the same balance, the winning platforms will be the ones that make self custodial money work everywhere a normal finance team already operates.
