What is Primary Network (Avalanche)?

The Primary Network is a special subnetwork (subnet) within the Avalanche blockchain ecosystem. All members of custom subnets — or blockchains that are created on the Avalanche platform — must also be a member of the Primary Network which requires them to stake 2000 AVAX coins. The Primary Network's main purpose is to validate, secure, and facilitate the different uses of the Exchange Chain (X-Chain), Platform Chain (P-Chain), and Contract Chain (C-Chain) of the Avalanche network — which are three independent networks responsible for different tasks on Avalanche.
