This code connects to a "dice game" that exists on the polygon mumbai ethereum testnet

This code creates an ethers ContractFactory using an abi and bytecode. The ContractFactory can then be used to deploy the contract to target EVM blockchain or create an instance of an already existing contract to be used as an interface.

from node.js REPL, use .load dice.js to create a connection to the blockchain and make available game functions.

once dice.js is loaded, the following commands are available.
