-Devnet is the network for early involvement and functionality testing before a
-release candidate is mature. It is meant for projects such as DApps that wish to
-explore new features as soon as they are available.

-(SPOs), and exchanges who wish to test mature release candidates.

-### Late-stage testing networks

-**Pre-production**
-
-Pre-production is the most mature network for testing purposes, which resembles
-a production (mainnet) environment. It is meant for exchanges, SPOs,
-pre-deployment DApps, and wallets that wish to test release functionality before
-deploying on mainnet.
