Bitcoin BTC$62,499.20 mining company GoMining said it is making it easier for companies to accept bitcoin BTC$62,499.20 payments, bringing it into competition with companies including Block’s (XYZ) Square.

Where GoMining says it differs from incumbents is that the entire transaction is completed in bitcoin. Many competitors, including Square, allow customers to pay in bitcoin while delivering fiat currency to the retailer. GoMining retailers who want fiat will need to handle the conversion themselves.

“Our idea isn’t to squeeze bitcoin into the old fiat experience and lose what makes it bitcoin along the way,” CEO Mark Zalan said in an interview over Telegram. “It’s to solve the real problems with BTC payments the high and variable fees, the slow and unpredictable settlement, while preserving non-custody and onchain finality.”

GoMining’s software development kit (SDK) and application programming interfaces (API) for its BTC payment protocol GoBTC Pay, unveiled Friday, enable retailers to access its GoBTC Pay system. The company plans to recruit an initial 10 merchants as part of the rollout, it said.
