Older networks

These are Arkiv testnets that have been retired.

Looking for a network to build on?

There isn’t a public one right now. A public testnet opens in September 2026, and an experimental devnet is running until then with limited access. Ask in Discord and we’ll get you set up.

Moving an old app forward

Entities don’t carry over between networks. Testnet state isn’t ported, so anything you wrote to Kaolin stayed on Kaolin, and anything you wrote to Braga stayed on Braga.

The next public testnet runs on a newer SDK version with breaking changes, so pointing your app at a new chain won’t be enough on its own. Full details follow once that testnet is live.
