Several cannabis retailers in Seattle have begun accepting Bitcoin after Washington state regulators approved the use of digital currencies by marijuana merchants and payment processors. The rollout is being driven by fintech startup Posabit, which offers a system that lets consumers buy bitcoin with a credit card and then use that bitcoin to pay at participating dispensaries.
Bitcoin Expands Into Seattle Dispensaries
According to the report, Posabit is working with four Seattle cannabis merchants, including Queen Anne Cannabis Company, Herb’s House, Greener Today, and three Uncle Ike’s locations. The company says its platform gives cannabis businesses and other brick-and-mortar stores an easier way to accept both credit cards and bitcoin at the point of sale, while also reducing dependence on cash.
That matters in the cannabis sector, where cash-heavy operations have long created security concerns. Keeping large amounts of money on site or transporting it to banks can expose dispensaries to robbery and other forms of loss. Posabit argues that software-based payment infrastructure can help remove some of that friction and make transactions safer for employees and merchants.
A Workaround to Credit Card Restrictions
Posabit’s model is designed around a legal distinction: customers are not using credit cards to buy cannabis directly. Instead, they first purchase bitcoin with a card and then spend that bitcoin at a dispensary using a Posabit kiosk. Co-founder Ryan Hamlin said federal law clearly prohibits using credit cards to purchase cannabis, and emphasized that Posabit is not doing that.
In effect, the company is using cryptocurrency as a bridge between consumer payment preferences and a sector that remains restricted under traditional card rails. That makes Bitcoin not just a branding tool, but a functional payment mechanism in a business category where conventional finance still has major limits.
Compliance and Auditability at the Center
Posabit also says its system is aligned with KYC, AML, and OFAC guidelines and provides real-time transaction histories for transparent reporting and auditing. The startup identifies three merchant categories that may benefit from its infrastructure: cash-only businesses seeking another payment method, tech-savvy merchants looking to differentiate themselves with Bitcoin, and micro-merchants aiming to lower transaction costs on small purchases.
More broadly, the Seattle rollout shows how cryptocurrency can gain traction in industries where payment friction is unusually high. For cannabis retailers operating under banking and card constraints, Bitcoin is being positioned as a practical tool to reduce cash exposure and expand payment flexibility within an approved regulatory framework.
