Stablecoin-backed Credit for Businesses
Rain
Rain is turning crypto treasury into spendable working capital without forcing customers to park cash at a bank. The key move is legal and architectural. Customers keep control of stablecoins in smart contracts they own, Rain treats those assets as collateral for a credit line, and the actual card spend runs through standard card rails. That lets crypto native businesses buy software, travel, and everyday operating needs while avoiding the bank deposit model that blocks many of them.

The practical flow is simple. A company posts USDC or similar stablecoins into a contract owned by its wallet, Rain extends a matching credit line, employees spend on Visa cards, and the company can repay by ACH, wire, check, wallet payment, or by releasing posted collateral. Rain never has to hold customer deposits to make the system work.

That is the core difference versus Brex and Ramp. Those products start with a bank linked business account and use cards as the wedge into expense software for CFO teams. Rain starts with customers whose revenue and treasury already live on chain, especially firms with on chain fee revenue that struggle to open or maintain ordinary bank relationships.

Compliance comes from staying out of the gray zone that triggers the hardest banking issues. Rain structured the product as asset backed credit, not a deposit account, does not custody or convert customer tokens, and built more of the stack in house to reduce reliance on bank and BaaS partners whose policies can change quickly.
If this model keeps working, stablecoin treasury stops being trapped balance sheet value and becomes a direct input into mainstream finance workflows. That pushes the market toward a hybrid stack where card networks and expense software stay familiar on the surface, while the funding layer underneath shifts from bank deposits to self custodied digital dollars.
