The infuraProvider configures the chains with Infura RPC URLs and also provides an ethers.js InfuraProvider.

If no Infura ID is provided, it will use the public Infura ID. It is recommended to provide your own Infura ID to prevent being rate-limited.

Lower-value priorities are favoured over higher-value priorities. If multiple providers share the same priority, they are chosen at random.

This can be used if a given provider is more trusted.
