 _section: Example: ERC-20 Contract

+The concept of Meta-Classes is somewhat confusing, so we will go
+over a short example.
+
+A meta-class is a class which is defined at run-time. A Contract
+is specified by an //Application Binary Interface// (ABI), which describes
+the methods and events it has. This description is passed the the
+[[Contract]] object at run-time, and it creates a new Class, adding
+all the methods defined in the ABI at run-time.
+

+be deployed to the blockchain, but for this example will will first

+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.
