 Some common actions you can perform using a provider include:
 
-* Getting the current block number
-* Getting the balance of an Ethereum address
-* Sending a transaction to the blockchain
-* Calling a smart contract function
-* Subscribe logs and smart contract events

 It is very common to wrap a provider in an `Arc` to share the provider across threads. Let's look at another example where the provider is used asynchronously across two tokio threads. In the next example, a new provider is initialized and used to asynchronously fetch the number of Ommer blocks from the most recent block, as well as the previous block.
