x402 payments on Base — week 33, 2026
Every week we publish the same numbers from our index of x402 / EIP-3009 USDC transfers on Base: no estimates, no third-party feeds, just what the chain shows. How we classify and score is described in the methodology.
This report covers 2026-08-10 to 2026-08-16 (UTC). The one number to take away: new addresses were up 75% on the week, and nearly half of them arrived in batches.
The index this week
| Metric | This week | vs previous week |
|---|---|---|
| Addresses in the index, total | 1,419,172 | — |
| New addresses first seen | 14,888 | up 75.1% |
| Transfers observed | 2,565,538 | up 56.1% |
| Volume moved | $7,204,944 | down 9.6% |
| Median transfer | $0.0060 | — |
| Distinct payers active | 17,573 | — |
| Distinct recipients active | 14,105 | — |
More transfers, less money: the count rose by half while volume fell, which is what a week of many very small payments looks like. Of the transfers we classified, 96.3% settled through a facilitator we track (confirmed); the rest match the x402 payment pattern without one (probable). 4,709 EIP-3009 transfers looked like something else entirely and are excluded from the x402 picture.
Payment behavior
Among recipients active this week with at least ten distinct payers in their history (629 addresses), the median share of one-off counterparties, payers who paid exactly once and never returned, was 45.2%. For 44 of them (7.0%), more than nine out of ten counterparties never came back. A high one-off share is not a verdict; it is one of the patterns we explain in every score, and on its own it is common among honest services with many one-time buyers.
Risk picture
This week 6,708 newly funded addresses arrived in 119 groups that share a single first funding source (counting only groups of ten or more). The largest such group holds 1,375 addresses. Shared funding is not proof of anything by itself, but it is exactly the pattern that batch-created address farms leave behind, and we watch it. Why it matters for anyone paying these addresses is in the x402 economy runs on disposable addresses.
Across the 187,567 addresses our nightly batch currently scores (the active set, not the whole index), the verdicts stand at:
| Verdict | Addresses |
|---|---|
| ok | 6,034 |
| caution | 39,412 |
| avoid | 142,121 |
