How many x402 settlements do facilitators send per day?

On 2026-11-08, known facilitator keys sent Base 89,721, Solana 29,571, Avalanche 2, Sei 2, Arbitrum 1, Robinhood Chain 1, Abstract 0, Ethereum 0, Monad 0, Optimism 0, SKALE Base 0, World Chain 0, X Layer 0 transactions, one figure per chain. That is transactions sent by known facilitator keys — an upper bound, not screened for self-payments; never summed across chains.

Why is this an upper bound on settlements?

A facilitator is the service that submits the payment transaction on a buyer's behalf, so its keys send settlements — but the same keys can also send other transactions (funding, approvals, retries). Counting every transaction a known key sent can only overstate settlements, never understate the ones those keys made.

What does 'not screened for self-payments' mean here?

The count keeps every transaction those keys sent. Nothing removes payments where the buyer and the seller are the same party, test traffic, or payments that circle back between the same wallets. It is what the chain shows those keys sending, with no reading of what each payment was for.

Which facilitators are counted?

Only keys attributed to a named operator on Sato Hub's facilitator map. Latest per-operator readings: Coinbase CDP on Base 87,517 (2026-11-08), FluxA on Base 27,706 (2026-11-07), PayAI on Solana 20,760 (2026-11-08), Coinbase CDP on Solana 7,778 (2026-11-08), PayAI on Base 1,306 (2026-11-08). A facilitator we cannot attribute is missing from every figure, which is one more reason the per-chain number is not the whole of x402.

Why is a facilitator missing from these figures?

Pieverse on BNB Chain is held from these figures since 2026-09-26: The first non-zero reading (2,210 transactions from key 0x1234…c78b, banked 2026-09-27 for the reading that ended 13:58 UTC that day) was not x402 settlements: every sampled transaction was an agent-identity mint on the operator's own registry contract 0xebf9…0c11, each to a different owner. The count is exact; it is not payment traffic. It returns when a sample of the keys' BNB Chain transactions shows EIP-3009 / x402 settlements rather than registrations. Polygon Facilitator on Polygon is held from these figures since 2026-09-26: One closed loop: every sampled settlement these keys sent pays $0.01 USDC to one address (0x66fa4d79ca84016b42352be33c908dd812952ec8) whose balance is swept to 0x897720c5b19f93f3194990d0121d3a64783bbab8, which tops the same 30 payers back up. The count is exact; the traffic is not independent commerce. It returns when a daily payee-concentration check shows these keys settling to more than one independent payee. Daydreams on Base is held from these figures for 2026-10-30, 2026-11-02, 2026-11-03: 60 of 60 settlements sampled from its keys on 2026-11-03 (100%) ended at one address, 0x3c08…83d8, from 43 payers. The count is exact and still stored; it is not shown as x402 activity while one recipient accounts for nearly all of it, because a single recipient cannot tell apart many buyers from one flow of payments. It returns when a day's sample no longer shows, with 95% confidence, one recipient taking 90% or more of its settlements. Dexter on Base is held from these figures for 2026-10-26: its keys sent 104 transactions on 2026-10-26, up from 0 in the previous reading, and we could not sample what they were (0 resolved EIP-3009 settlements, under the 50-settlement floor — decides nothing; nonce-targeted sample not taken: sample time budget reached after 54 of 60 blo). The count is exact and still stored; a new or sudden series nobody has checked is not shown as x402 activity. It returns when a sample of at least 50 of its transactions is read, or a person has checked the day. FluxA on Base is held from these figures for 2026-10-26, 2026-10-27, 2026-10-28, 2026-10-29, 2026-10-30, 2026-10-31, 2026-11-01, 2026-11-02, 2026-11-03, 2026-11-04, 2026-11-08: 60 of 60 settlements sampled from its keys on 2026-11-08 (100%) ended at one address, 0xfe80…47ee, from 57 payers. The count is exact and still stored; it is not shown as x402 activity while one recipient accounts for nearly all of it, because a single recipient cannot tell apart many buyers from one flow of payments. It returns when a day's sample no longer shows, with 95% confidence, one recipient taking 90% or more of its settlements. FluxA on Base is held from these figures for 2026-11-05: 60 of 60 settlements sampled ended at one address (100%, lower bound 94%). It returns when a later day's screen no longer holds it. OpenFacilitator on Base is held from these figures for 2026-10-31: its keys sent 57 transactions on 2026-10-31, up from 1 in the previous reading, and we could not sample what they were (0 resolved EIP-3009 settlements, under the 50-settlement floor — decides nothing; sample time budget reached before a nonce-targeted sample). The count is exact and still stored; a new or sudden series nobody has checked is not shown as x402 activity. It returns when a sample of at least 50 of its transactions is read, or a person has checked the day. Coinbase CDP on Base is shown, with a note for 2026-10-27, 2026-10-28, 2026-10-29, 2026-10-30, 2026-10-31, 2026-11-01, 2026-11-02, 2026-11-03, 2026-11-04, 2026-11-05, 2026-11-06, 2026-11-09: Only 15 settlements were sampled, below the 50 needed to screen on these shares; the largest share was 53%. Funding was not read, so returned-funds, common-funder and self-pay shares were not screened. Coinbase CDP on Solana is shown, with a note for 2026-10-27, 2026-10-28, 2026-10-29, 2026-10-30, 2026-10-31, 2026-11-01, 2026-11-03, 2026-11-05, 2026-11-06, 2026-11-07, 2026-11-08, 2026-11-09: 30 of 50 settlements sampled ended at one address (60%).

Tempo MPP (memo-tagged transfers) on Tempo is shown, with a note for 2026-10-27, 2026-10-28, 2026-10-29, 2026-10-30, 2026-11-01, 2026-11-02, 2026-11-03, 2026-11-04, 2026-11-05, 2026-11-06, 2026-11-07, 2026-11-08, 2026-11-09: 45 of 120 settlements sampled ended at one address (38%). 27 of 61 payers were funded from the payee's sweep destination or the payee itself. 27 of 61 payers were first funded by the same address. three.ws on Solana is shown, with a note for 2026-10-27, 2026-11-01, 2026-11-02, 2026-11-03, 2026-11-07, 2026-11-08, 2026-11-09: 27 of 50 settlements sampled ended at one address (54%). 50 settlements came from only 2 payers, below the 50 needed to screen on payer shares; the largest payer share was 100% (2 of 2).

Why is there no total across chains?

A transaction on Base and one on Solana are settled on different ledgers by different keys under different fee regimes, and the attributed key set differs per chain. Adding them would produce a number that describes no chain.
