web3_clientVersion code examples

Use case

A use case for the web3_clientVersion method can be to verify which client is running to then decide which method to run.

Let’s say you have a DApp that needs to retrieve all of the transaction receipts in a block; the Erigon client has a method for this, eth_getBlockReceipts, but with Geth, this method is only available starting from V1.13.0. You can use the web3_clientVersion method in your logic to identify which client you are using to see if you have the method available.
