The Arc Ecosystem Map: Every Live App, Updated Weekly

This is the living directory of what actually runs on Arc — every named app, categorized, one line each, maintained as the ecosystem grows. Circle reports 100+ builders were on Arc's private mainnet before launch; this page lists what's publicly named and live, and adds entries weekly as they ship.

How to read this map

Two honest notes. First, "named in the day-one cohort" means Circle publicly named the participant at launch; the depth of each integration varies and deepens at its own pace — this page tracks liveness, not endorsement. Second, the list is deliberately conservative: 100+ builders were on private mainnet, and entries appear here as they publicly ship, not before. A young ecosystem's map should undersell rather than pad — check back weekly as it fills in, and see the timeline for how fast the network got here.

How do I get my Arc project listed here? Be live on Arc mainnet with a verifiable deployment. Projects with on-chain trust signals — locked liquidity, published vesting — are annotated as such.

Where do I check whether an app is really on Arc? On-chain, via Arcscan — a deployment either exists at a verified address or it doesn't. Take contract addresses from the project's official channels only.
