# Ethereum Chains

API Miner can interact with any arbitrary Ethereum network as long as a connection to it has been made. This means that sometimes a request needs to specify which network it's operating on.

When a network needs to be specified, it's typically specified using the system name for that network, although chain ID is also accepted. For example, to use the main Ethereum network, you'd specify either "main" or 1 - the two are equivalent.
