New ERC-8004 agent identities. Registrations on 2026-10-15, per chain — top 4 of 26 chains read. Chains are never added together.
x402 facilitator throughput. Transactions sent by known facilitator keys — an upper bound, not screened for self-payments. Not every such transaction is an agent paying for something. Held from these figures: Pieverse on BNB Chain; Polygon Facilitator on Polygon; Figment on Solana; FluxA on Base; three.ws on Solana — the readings are exact but are not shown as x402 activity while the evidence behind each hold stands. Some shown readings carry a note about what the sample could not see. An operator is held for a day automatically when, on at least 50 sampled settlements, we are 95% confident that 90% or more of them paid one address — and when a new or sudden reading of 50 or more transactions could not be sampled at all, until it is checked. Reasons and evidence are on /numbers/x402-facilitator-throughput.
Listed x402 resources that answer HTTP 402. A sample of Bazaar listings probed that day; answering 402 means the endpoint asks for payment, not that anyone paid.
A day counts once it is over in UTC and our daily read has finished it; today's partial readings never appear here. Each figure is one chain or one operator. None is a total.

Each registry or rail counts a different thing. Open one for its full numbers.
Can't be read onchain
These providers mint ordinary EOAs from a TEE or MPC ceremony — a Privy wallet is indistinguishable from a MetaMask wallet by construction.
Each registry or rail counts a different object and charges a different price of entry. Free and permissionless is not the same market as bonded, and a launchpad is not a registry. Each card shows the largest single chain; open it for every chain and step.
How measured · RedeemedDelegation events on the singleton DelegationManager over the trailing window, read with eth_getLogs and no sampling; a grant emits nothing, so this is a floor on permissions granted. The trailing window, read once a week.
How measured · The ERC-8004 Identity Registry's own agent-id counter (`_lastId`, one storage read at the chain head) on that chain, covering the whole registry with no sampling. The latest daily reading.
How measured · totalSupply() on the confirmed Olas service registry contract on that chain. The latest weekly reading.
How measured · The length of the public tokenInfos array on Virtuals' BondingV5 contract on Base, found by binary search for the first index that reverts. The latest weekly reading.
How measured · For every catalogued x402 facilitator key, the transactions it sent in the last complete UTC day (on EVM chains its nonce at the last block before each UTC midnight, end minus start; on Solana its fee-payer signatures in that day), summed per chain over the operators not held from public figures — an upper bound on settlements, not screened for self-payments. The last complete UTC day.
Registries that can't be read onchain are listed with the reason, because a missing fingerprint is itself a finding.
Sato Hub measures 12 of 13 agent platforms from public chain data on 13 chains, each reported on its own, as of 2026-10-16.
13 of 46 confirmed smart-account contracts have no directory listing to attribute them to. Privy (server and embedded), Turnkey, Coinbase CDP Server Wallets, Dynamic and Fireblocks can't be measured from chain data at all: they mint ordinary EOAs, and when their user deploys a smart account the factory belongs to a different company. So the Wallet providers view covers account-abstraction vendors well and wallet-infrastructure vendors not at all. That follows from how these wallets are built; more effort would not close it.
