x402 is a payment standard and Virtuals ACP is a commerce protocol, so they measure different acts: x402 counts per-request stablecoin settlements, while ACP counts lifecycle memos inside agent-to-agent deals. As of August 12, 2026, x402 has recorded 162,161,335 settlements moving $41,284,271 across 12 chains, and Virtuals ACP has recorded 12,333,677 memos. The counts are not comparable one-to-one — a memo is a step in a deal, not a completed sale.

They answer different questions
x402 is a payment standard. It revives the dormant HTTP 402 status code so a server can demand payment for a single request and an agent can settle it in stablecoins without an account, a subscription, or a human. Its unit is a settlement, and because settlement happens in stablecoins, it carries a dollar figure that can be summed.
Virtuals ACP is a commerce protocol. It structures a deal between two agents into recorded lifecycle steps — request, negotiation, transaction, evaluation — so that agent-to-agent work has an auditable trail. Its unit is a memo, and a memo is a step in a deal, not a completed sale. Counting memos as transactions overstates completed commerce, which is why this site never blends the two totals.
What the comparison does and does not tell you
Because the units differ, the larger number is not the more successful protocol. A single ACP job can produce several memos, and a single x402 settlement can be a test call or infrastructure traffic rather than end-user demand. The useful reading is directional: which one is accelerating, and whether payment volume is growing faster than the count of payments, which would indicate larger individual transactions rather than merely more of them.
They are also not competitors in any strict sense. A job negotiated through ACP still has to be paid for, and x402 is one of the rails that could settle it. Treat them as adjacent layers — commerce coordination above, per-request payment below — rather than as rivals for the same slot.
Also asked
Does Virtuals ACP use x402?
They are adjacent layers rather than substitutes: ACP coordinates the deal between agents, and the payment still has to settle on some rail, of which x402 is one. This site measures each independently and does not assume any settlement path between them.
Which one is bigger?
By raw count x402 is larger — 162,161,335 settlements against 12,333,677 memos — but the units are not equivalent, so the comparison is directional, not a ranking. x402 is also the only one of the two with a measurable stablecoin volume, at $41,284,271.
