On Friday, GoMining pushed GoBTC Pay from protocol pitch into merchant tooling, unveiling an SDK and API access for retailers that want to accept bitcoin directly at checkout.
The move puts GoMining in a sharper fight with Jack Dorsey’s Square, because the company’s core claim is not just that shoppers can pay in BTC. It’s that merchants receive BTC by default, according to CoinDesk.
Friday’s GoBTC Pay SDK puts bitcoin-native settlement at the center
GoMining said the new software development kit and application programming interfaces give retailers access to GoBTC Pay, its bitcoin payment protocol for everyday purchases.
That matters because GoMining is not copying the common crypto checkout model, where the customer pays in bitcoin but the merchant receives fiat. CoinDesk reports that GoMining’s system completes the transaction in bitcoin. Retailers that want fiat have to handle 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.”
The first rollout target is modest. GoMining plans to recruit an initial 10 merchants, CoinDesk reported. That makes this less a mass-market deployment than a controlled test of whether a bitcoin-first payment rail can work in live commerce.
GoBTC Pay’s primary search relevance is clear: GoBTC Pay is being positioned as merchant bitcoin payments infrastructure, not just another wallet feature.
GoBTC Pay differs from Square by making BTC the default outcome
The key distinction is settlement. GoMining says merchants receive bitcoin by default. Square’s bitcoin payments service, by contrast, converts the bitcoin amount into U.S. dollars by default unless the merchant chooses to receive BTC, according to CoinDesk.
That difference creates two very different merchant propositions.
| Feature | GoMining GoBTC Pay | Square bitcoin payments |
|---|---|---|
| Merchant default | Receives bitcoin | Receives U.S. dollars by default |
| Fiat conversion | Merchant handles it | Square can convert by default |
| Network approach | Settles on Bitcoin network using GoMining’s Stratum V2 mining protocol | Uses Bitcoin Lightning |
| Reported merchant fee | 0.2% | Forbes reported zero processing fees until 2027 |
| Initial rollout | 10 merchants planned | Forbes reported Square products are used by over 4 million merchants |
GoMining’s system uses its Stratum V2 mining protocol and has an average settlement time of around 12 hours, CoinDesk reported. Merchants pay 0.2% in transaction fees, split 50-50 between wallet providers and miners.
Square has a distribution advantage. Forbes reported that more than 4 million merchants use Square’s products, and that Square Bitcoin lets merchants accept bitcoin and keep it, convert it to fiat, accept fiat, or convert fiat to bitcoin. That scale is the wall GoMining is trying to climb.
XOOMAR analysis: GoMining is making a purity bet. Square is reducing merchant friction by letting bitcoin enter the checkout flow without forcing the merchant to hold BTC. GoMining is betting some merchants want the opposite: direct bitcoin receipt, non-custody, and onchain finality, even if fiat conversion becomes their own problem.
That split mirrors a broader payments debate we’ve tracked in fintech. Visa is pushing machine-driven commerce through AI agent payments, while crypto-native firms are still trying to make digital assets practical at checkout. We also covered how Alchemy AgentCard connects AI shoppers to Visa payments, a very different path from GoMining’s bitcoin-first design.
The 12-hour settlement claim is the pressure point
GoMining says GoBTC Pay is built to address “high and variable fees” and “slow and unpredictable settlement,” while keeping non-custody and onchain finality. The company’s reported average settlement time of around 12 hours gives merchants a concrete benchmark to judge.
That benchmark cuts both ways. It may appeal to merchants that care more about bitcoin-native settlement than instant finality. But it also raises a practical question: can GoBTC Pay feel natural at checkout if the final settlement clock is measured in hours?
Square’s use of Lightning points to the opposite design choice. Lightning is built for faster, lower-cost bitcoin payments, and Square’s default fiat receipt reduces the accounting and treasury burden for merchants that don’t want BTC exposure.
GoMining’s answer is narrower and more ideological: preserve bitcoin’s properties rather than wrap BTC in a fiat checkout experience. That could appeal to bitcoin-aligned merchants. It could also limit adoption if businesses mainly want lower fees without managing conversion.
The timing lands while bitcoin remains under pressure in markets. We recently covered how Bitcoin broke below $63K as a peace-deal bounce unraveled fast, and CoinDesk’s page data listed BTC at $62,439.20. Price action does not determine whether GoBTC Pay works, but it does shape how comfortable merchants feel holding bitcoin after checkout.
The first 10 merchants will decide whether this is infrastructure or announcement
GoMining’s next test is not technical language. It’s merchant use.
The company has disclosed the SDK, API access, fee model, settlement design, and initial recruitment target. It has not yet shown broad adoption, named the first merchants in the supplied material, or provided transaction volume.
The near-term proof points are specific:
- Merchant signups: Whether GoMining reaches and expands beyond the initial 10 merchants.
- Developer adoption: Whether builders actually integrate the GoBTC Pay SDK into checkout products.
- Settlement performance: Whether the reported average of around 12 hours holds in live use.
- Fee economics: Whether the 0.2% fee split between wallet providers and miners is attractive enough for merchants.
- Conversion behavior: Whether merchants choose to keep BTC or regularly move into fiat on their own.
Challenging Square requires more than a bitcoin-native architecture. GoMining needs distribution, merchant trust, and evidence that everyday BTC payments can survive real checkout demands.
The next decision point is the initial merchant rollout. If GoBTC Pay moves from SDK access to visible transaction activity, GoMining will have a real case that bitcoin-native settlement has a merchant audience. If adoption stalls at the first 10, Square’s easier default-to-fiat model will look less like compromise and more like product discipline.

The Bottom Line
- GoBTC Pay tests whether merchants will accept bitcoin directly instead of treating it as a fiat-converted payment option.
- The launch creates a clearer competitive challenge to Jack Dorsey’s Square in bitcoin payments.
- The initial 10-merchant rollout will show whether bitcoin-native settlement can work in real commerce.
