The State of Agent Payment Data
Reported figures for agent-to-agent payment volume diverge by orders of magnitude, and the divergence itself is evidence that no shared system of record exists.

The claims
| Figure | Measures | Source | Period | Why it differs |
|---|---|---|---|---|
| ~$73M settled across ~176M agent transactions | On-chain settled agent payment volume and count | Nevermined on-chain analytics (market-update release) | May 2025–Apr 2026 | On-chain settlement definition; includes counted agent tx set |
| ~$600M annualized x402 payment volume | Annualized x402 payment volume estimate | BlockEden analysis (via Nevermined stats roundup) | as reported mid-2026 | Annualized / issuer-ecosystem framing vs raw on-chain sample |
| Solana ≈49% of x402 volume; Base the remainder | Chain share of x402 volume | BlockEden / Nevermined | Apr 2026 | Volume-share window and chain classification |
| Base ≈85% of x402 transaction volume | Chain share of x402 transactions | Base Foundation-cited data via RZLT | Apr 2026 | Transaction-count share vs dollar volume; different source set |
| 100M+ agentic payments on Base | Cumulative agentic payment count on Base | Chainalysis via DropsTab research | by mid-2026 | Count of payments, not dollar volume; Base-only |
| ≈$28K/day independently verifiable on-chain x402 usage | Independently verifiable daily on-chain x402 usage | DropsTab research | as reported mid-2026 | Strict verifiable on-chain sample vs issuer-reported aggregates |
| XRPL agentic tx: 1M (Jul 8) → 1.43M (Jul 22) → ~2M (Aug 2026) | XRPL agentic transaction counts | t54.ai / XRPL validator reports via Finbold & Coinpaper | Jul–Aug 2026 | Ledger-specific facilitator counts; not global x402 volume |
| x402 Foundation member tiers $25K / $50K / $75K; Premier $200K | Governance membership fee tiers (not payment volume) | x402.org/members | 2026 | Institutional membership economics, not agent transaction volume |
Why the numbers disagree
There is no shared definition of an agentic transaction. Free-tier pings, test traffic, mint-and-burn flows, and paid settlement can all be counted or excluded depending on who is measuring. Issuer-reported aggregates and independently verifiable on-chain samples answer different questions. Chain-share figures are measured over different windows and sometimes confuse transaction count with dollar volume.
In a mature market, disagreement this wide usually means fraud or error. Here it usually means the category has rails and invoices before it has a system of record. Until attribution joins telemetry, billing, and settlement under common keys, every headline number remains a local definition dressed as a global fact.
That is why this page exists: not to pick a winner, but to keep the conflict visible and sourced — so enterprises do not mistake a payment-volume headline for a closeable ledger.
Methodology note
Onaro reports figures as published by their sources and does not independently verify on-chain data — yet.
