Solana Pay Targets 330,000 Merchants in South Korea

Distribution Is the Hard Part, and This Is Distribution

KSNET, one of South Korea's largest payment processors, signed a memorandum of understanding with the Solana Foundation on July 30, 2026 to integrate Solana Pay across its merchant network. The scale is what makes this notable: more than 330,000 merchants, roughly 130 million transactions a month, and about $4 billion in monthly payment volume already flowing through the network that would be receiving the integration.

• More than 330,000 merchants in KSNET's network, covering both online and offline payments
• Around 130 million transactions monthly, representing approximately $4 billion in monthly volume
• A joint proof of concept using x402, an emerging payment standard designed for AI agents to initiate and settle payments
• Currently an MOU rather than a commercial rollout, with integration into existing merchant infrastructure planned

Why Merchant Acceptance Is the Metric That Matters

Crypto payments have never had a technology problem. Settlement is fast, fees are low, and the rails have worked for years. What they have had is an acceptance problem: consumers do not use a payment method their local shop does not take, and shops do not integrate a payment method their customers do not ask for. It is a coordination deadlock, and most attempts to break it have started from the consumer side, which is the harder end.

Going through an established processor inverts that. KSNET merchants do not need to evaluate blockchain payments, negotiate a contract, or install new hardware — the capability arrives through infrastructure they already run. That is how card networks, mobile wallets, and QR payments all achieved scale, and it is a considerably more realistic path than persuading 330,000 businesses one at a time. Our crypto coverage saw the same structural logic behind Circle's USDC payment rails deal in South Korea earlier this month.

What Is x402, and Why Include It Here?

x402 is an emerging standard for machine-initiated payments — the plumbing that would let an autonomous software agent pay for something on its own behalf, with settlement and authorization handled programmatically rather than through a checkout page built for human hands and eyes.

Including a proof of concept for it in a merchant-acceptance agreement is forward-looking in a way most payment partnerships are not. If AI agents are going to transact — buying compute, paying for data, settling small amounts between services — they need rails that clear in seconds, work without a card-present flow, and support amounts too small for interchange fees to make sense. That description fits blockchain settlement considerably better than it fits the card system, and it is the same convergence we tracked in Samsung Wallet's move to native stablecoin support.

How Much Should an MOU Count For?

Less than a launch, more than nothing, and the distinction is worth respecting. A memorandum of understanding establishes intent and a working relationship; it does not commit either party to a shipping date, a transaction volume, or a specific technical integration. Plenty of them quietly expire.

What gives this one weight is that KSNET is not a startup testing a thesis. It is an incumbent processor with a live merchant base and real volume, and incumbents generally do not put their name to exploratory agreements in payments unless there is internal appetite behind it. The signal is that a major Korean processor now views blockchain settlement as part of its roadmap rather than a competing category — and South Korea, with its unusually high crypto participation rate and dense card infrastructure, is a sensible place to test that.

What to Watch Next

Two things will tell you whether this becomes infrastructure. First, whether the integration reaches point-of-sale terminals rather than only online checkout — offline acceptance is where the 330,000 number actually lives. Second, whether the x402 proof of concept produces anything shippable, because agent-initiated payments are still an idea in search of a production deployment.

Either way, the direction is consistent with everything else happening in payments this year: settlement rails are being chosen on technical merit, and the distribution partners deciding it are the ones who already own the terminals.
