Treasury Prime plugs cash deposits into BaaS with Green Dot retail network

The last decade of fintech largely wrote cash out of the story, building deposit flows around cards, ACH and instant transfers while leaving cash-reliant customers without a clean route into a digital balance. Treasury Prime is moving to close that gap. On 20 May 2026 the banking-as-a-service platform launched Prime Cash, a service that lets its fintech clients accept physical cash deposits at more than 90,000 retail locations across the United States, including Walmart, CVS, Walgreens and 7-Eleven, with no branch visit required.

The mechanics are deliberately simple. A customer generates a unique, time-sensitive barcode inside the fintech's app, presents it at a participating retailer and hands over paper bills. Funds are typically credited to the account within minutes. The network behind it is the Green Dot Network, reached through a single API integration, with Treasury Prime managing the underlying network rules and compliance workflows on behalf of its clients.

Why a cash rail matters for BaaS

Building a physical cash-in capability has historically meant bespoke deals with armoured transport networks or accepting tight geographic limits, putting it out of reach for most digital-first programmes. By turning that infrastructure into a turnkey API, Treasury Prime lowers the barrier for neobanks and embedded-finance providers to serve underbanked and cash-dependent users, a segment many fintechs have effectively excluded by design.

The timing is pointed. With competition for deposits still fierce, a friction-free route from paper currency to a digital ledger gives Treasury Prime's bank partners a fresh funding channel rather than relying solely on transfers from rival institutions.

"Financial access shouldn't depend on whether a customer uses cash or digital rails," said Chris Dean, CEO of Treasury Prime. "With Prime Cash, fintechs can meet customers where they are, unlocking new growth opportunities while expanding access to essential financial services. Our platform also ensures financial institutions retain visibility and governance over transactions as they scale."

Prime Cash is available now through Treasury Prime bank partners that have enabled the Green Dot integration.
