What's live on Arc· 121
As of 28 September 2026, Built on Arc tracks 121 projects observed working on mainnet on Circle's Arc. These projects were observed working on Arc for real customers on the dates shown. Each entry carries the source we checked and the day we checked it, so you can confirm the claim yourself rather than take ours. Statuses change in both directions — a project that goes quiet moves to Inactive, and we say when we last looked. If something on this page is out of date, tell us and we will re-check it.

Questions
What has to be true for a project to be Live?
We observed the product working on Arc mainnet for real customers, with a source we can link, on the date shown.
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.
Which Arc does this site cover?
Built on Arc covers Circle's Arc, the stablecoin-native Layer-1 blockchain (mainnet chain ID 5042; testnet 5042002) that launched mainnet on 16 September 2026. It does not cover the ARC token, Aave Arc (a 2022 permissioned lending pool), Arc Raiders, Azure Arc or the Arc web browser.
Is Arc mainnet live?
Yes. Circle's Arc mainnet launched on 16 September 2026 (chain ID 5042). Built on Arc tracks which projects are observed on mainnet, which are only on testnet, and which have only been announced.
