Not listing counts, not press releases — actual stablecoin settled to the wallets that agent services get paid at. We count every payment we can verify at the settlement layer and tell you exactly what we can’t yet see.
Snapshot 2026-09-05. Tracking since 2026-07-11 (58 daily points).
Every stablecoin payment we can verify at the settlement layer, wash included.
of all settlement goes to a single counterparty (Bitrefill). Most of what looks like an economy is one participant.
of the remaining $1,149,685.84 — agents actually paying agents — is wash by our published rules.
We lead with this rather than bury it. The concentration is visible in our own Gini (0.996275) and top-wallet share, so anyone checking would find it in a minute; a number quoted without it is misleading even when it is arithmetically correct. The step-2 figure is pure arithmetic and needs no interpretation. We additionally classify Bitrefill as consumer commerce rather than agent-to-agent settlement — a documented judgement, not a heuristic, recorded with its reasoning and versioned by wash_rule_version. That classification is supporting detail: step 2 holds whether or not you accept it. Both views are sealed into the integrity chain, so neither can be quietly revised later.
Directories advertise 72,159 listings. But only 2,095 wallets have ever been paid — about one real earner for every 34 listings. We lead with what got paid, and treat the listing count as context, never the headline.
Of $4,534,114.09 in gross on-chain settlement, $648,271.62 (14.3%) across 171 wallets is single-payer self-funding or non-production traffic — e.g. one wallet takes tens of thousands from a single payer. We report the validated floor of $3,885,842.47 and show the raw number beside it, never instead of it. How we adjust →
| Chain | Settled volume | Share | Real providers | Active (24h) |
|---|---|---|---|---|
| base | $1,650,377.80 | 36.4% | 1,765 | 440 |
| arbitrum | $1,299,502.85 | 28.7% | 12 | 4 |
| polygon | $1,242,271.64 | 27.4% | 20 | 3 |
Base, Polygon, Arbitrum, Ethereum and Solana measured directly via on-chain USDC/USDT/PYUSD Transfer logs. Other non-EVM rails (Stellar, Noble/Cosmos) are not yet in these totals — see coverage below.
Today the economy is heavily concentrated — a single wallet accounts for 74.6% of measured volume. Early markets look like this; we’ll track whether it decentralizes over time.
Different populations (all quoted services vs. wallets that actually earned), shown side by side so you can judge whether listed prices reflect real demand.
Asset mix: USDC 99.6% · USDT 0.3% · USDC.e 0.0% · 0x0b2c639c 0.0%
Uptime, size distribution, asset mix and payer retention are captured forward-only from on-chain settlement and live endpoint probes.

Everything above is measured on-chain. But most of the world’s agent payments happen off-chain, inside Asian super-apps and card networks — walls we can’t see behind. We track what they report so you get the whole board; these figures are operator-reported, not verified by us, and never mixed into our measured numbers.

Reported by the named operators via public announcements. The on-chain economy we measure is a fraction of this; the two rails may converge at cross-border stablecoin settlement.
