Role

Serving the Arc ecosystem· 60

As of 28 September 2026, Built on Arc tracks 60 services other projects depend on on Circle's Arc. These are the services other Arc projects depend on: RPC endpoints, oracles, indexers and explorers, custody and key management, compliance tooling, account abstraction, automation. Live means the service is usable against Arc today by anyone who signs up — an endpoint that answers, an explorer that resolves, a feed that updates. Service providers deploy little or nothing themselves, so on-chain checks generally do not apply. The evidence that matters is whether the thing works, and the entry links what we checked.

Questions

What makes a service entry Live?

The service is publicly usable against Arc on the date we checked, with a linkable source such as documentation, a status page or the endpoint itself.

How is status decided?

Status reflects what we observed on the date shown, not what a project announced. Every entry carries a dated source you can open and check yourself. Live can become Inactive if activity stops.

Does paying change where a project appears?

No. Paid entries are labelled Listing, sit in the same ranked order as everything else, and use rel="sponsored". Payment never affects status, flags, evidence or the Editor's Index.
