_subsection: StaticJsonRpcProvider @<StaticJsonRpcProvider> @INHERIT<[[JsonRpcProvider]]> @SRC<providers:class.StaticJsonRpcProvider>
An ethers Provider will execute frequent ``getNetwork`` calls to ensure
the network calls and network being communicated with are consistent.
In the case of a client like MetaMask, this is desired as the network
may be changed by the user at any time, in such cases the cost of
checking the chainId is local and therefore cheap.
However, there are also many times where it is known the network cannot
change, such as when connecting to an INFURA endpoint, in which case,
the **StaticJsonRpcProvider** can be used which will indefinitely cache
the chain ID, which can reduce network traffic and reduce round-trip
queries for the chain ID.
This [[Provider]] should **only** be used when it is known the network
cannot change.
