Role

Serving the Arc ecosystem · 60

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.
