Does releasing a testnet mean the mainnet is live? No. Generally, a testnet is a separate environment for development, integration testing, and trial use. Its tokens and state are usually not equivalent to those on the mainnet; the mainnet is where real assets and production deployments reside. “Testnet released” only proves that a test environment is available; it does not automatically mean that the “mainnet is live.”

Suppose a project opens its testnet, and you can claim test tokens and see the contract in a testnet block explorer. This only shows that the testing process is working; it does not prove that the same functionality has been deployed to the mainnet. If the official team later explicitly identifies the mainnet and provides the corresponding deployment address and a working entry point, then you should update your assessment. Otherwise, treat it as a testnet.

To check in practice, open the official documentation and a block explorer, verify that both the network name and deployment address point to the mainnet, and then check which network your wallet is currently connected to. If anything doesn’t match, don’t treat it as a mainnet launch.
