risk data for machine payments
Measured directly
Market overview
Base blocks are read in full; Solana is read from known facilitators. Every row maps to a specific transaction — nothing is extrapolated or filled in. Window: 30 days.
Why the mean ticket is useless here
There are 1,022 such payments — 0.4% of the count. These are ordinary gasless stablecoin transfers, not API calls: a few hundred dollars has nothing to do with machine commerce.
So our headline figure is the median, $0.00549. The mean ($7.14) sits beside it for completeness. Any market estimate built on the mean ticket is off by orders of magnitude.
Ticket size distribution
| Ticket | Payments | Share of count | Share of volume |
|---|---|---|---|
| ≤ $0.01 | 159,763 | 64% | <0.1% |
| $0.01–0.10 | 73,382 | 29% | 0.1% |
| $0.10–1 | 8,054 | 3% | 0.3% |
| $1–100 | 7,280 | 3% | 5% |
| > $100 | 1,022 | 0.4% | 95% |
The two right-hand columns tell the whole story: nearly every payment is tiny, while nearly all the volume sits in a handful of large transfers.

A one-off wallet is a test or a demo. Only someone who pays regularly can become a customer. Payers with scores →

By network
| Network | Payments | Median | Volume | Payers | Recipients |
|---|---|---|---|---|---|
| Base | 239,534 | $0.00500 | $1.8M | 9,554 | 9,717 |
| Solana | 9,967 | $0.01 | $371.97 | 110 | 101 |
Polygon and Arbitrum are excluded on purpose: a full block census found four payments in two hours on Polygon (mean ticket $33, so not x402) and none at all on Arbitrum.
