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.
