ERC-8004 registered agents, by chain
The number of agent ids the ERC-8004 Identity Registry holds on each chain where the singleton is deployed, read weekly from the contract itself — latest week starting 2026-09-07, read 2026-09-07. One row per chain. There is no total on this page, on purpose: a registration on one chain and a registration on another are different objects on different contracts, and the registrations counted here include test, duplicate and abandoned ids.

- Method
- lastAgentId (_lastId, ERC-7201 namespaced storage slot) on the singleton Identity Registry The Identity Registry is one contract deployed at the same address on every listed chain; the counter is read directly, so the count is exact for that chain on that day (evidence tier 1).
- Unit
- registered agent id. An id is minted by any call to register(); it says nothing about whether the agent is funded, active or real. The funnel after registration is on the venue page.
- Cadence
- Weekly (Monday run). Series start 2026-08-31; this page refreshes with the weekly job.
- Reproduce
- GET /api/export/adoption.json → rows where venue="erc8004" and stage="registered" · MCP onchain_agent_get_trend(venue="erc8004", stage="registered", chain=…)
