Stablecoins settled roughly $390 billion in genuine payments during 2025, according to McKinsey. That is about 0.02 percent of global payments volume.
Hold both figures at once before you decide to accept crypto payments. The first is large enough that ignoring the rail is a decision rather than an oversight. The second is small enough that most checkout buttons installed this year will sit unused.
BCG’s January 2026 white paper reaches the same place from the other direction, finding that only about 7 percent of the roughly $62 trillion in gross stablecoin transfers during 2025 tied to real economic activity. Card-linked spending, the slice that looks most like a retail checkout, came to $4.5 billion on McKinsey’s numbers, up 673 percent in a year. Small and compounding, not small and flat.
The generic advice is to pick a gateway and paste the checkout code. That skips the two decisions that decide whether this works. What happens to the money the second it arrives, and whether anyone was going to pay you this way at all.
Surgence Labs is a crypto marketing agency that supports funded Web3 teams through launch and growth windows, including stablecoin issuers, exchanges, and payment protocols that sit on this rail.
This guide covers what acceptance means, the true all-in cost, the four integration models, the demand test to run first, the week-by-week setup, and the obligations that decide whether the project survives its first month-end.
