# Every project building on Arc

Registrai's Arc ecosystem directory lists 261 projects on Circle's Arc blockchain with their status and evidence: 112 live on mainnet, 20 deployed, 129 announced. Last reviewed 2026-10-25.

## What counts as on Arc

Every project with a public Arc link: contracts on Arc mainnet, a live integration, or an official announcement. Each status links to its evidence on the project page.

## How a status is decided

- Live: running on Arc mainnet, shown by mainnet evidence (contracts on Arc mainnet, an index id, an explorer link, the project's own mainnet support page, or an official Arc or Circle post saying it is live).
- Deployed: built on Arc but not yet open for use on mainnet, per its own docs or contracts.
- Announced: an announcement only, with no deployment we can show.

Launch dates come only from a source dated that day. [Method](https://builder.registrai.cc/methodology/)
