While most users will only ever interact with the TON mainnet, Tonkeeper for Android offers advanced users and developers the flexibility to connect to different networks. Through its settings, the wallet typically allows selection between the mainnet, testnet, and possibly other development networks. This is crucial for developers who need to test their smart contracts and dApps in a risk-free environment where tokens have no real value. Furthermore, advanced settings might allow users to connect to a custom RPC (Remote Procedure Call) endpoint. This could be useful for accessing a private TON network or for using a specific node provider for enhanced privacy or reliability. The ability to configure these settings demonstrates the versatility of the tonkeeper application. It caters not only to the end-user but also to the builders of the ecosystem, providing them with the necessary tools to develop, test, and deploy applications on the TON blockchain directly from their Android device.
