-In the example above, the `ERC20.poolInfo` is declared `eth_call`. The text before colon(`ERC20.poolInfo`) is the label for this `eth_call` which is used when logging errors. The text after colon(`ERC20[event.address].getPoolInfo(event.params.to)`) is the actual `eth_call` that will be executed which is in the form of `Contract[address].function(arguments)`. The `address` and `arguments` can be replaced with actual values or variables which will be available when executing the handler.

 When declared `eth_calls` are used, `graph-node` caches the results in the memory and when the `eth_call` is triggered inside handlers, it fetches the result from the cache instead of making an actual RPC call.
