The debug_storageRangeAt method returns the contract storage range for a given block and address on the Optimism network. This method retrieves a specified range of storage keys and their corresponding values from a contract's storage at a particular block height. It's particularly useful for debugging smart contracts and analyzing storage layouts, as it allows developers to inspect the state of contract storage at any point in blockchain history.

Parameters

parameter	type	description
blockHash	string (required)	The hash of the block to query storage from

startKey	string (required)	The starting storage key (32-byte hex string)
maxResult	integer (required)	Maximum number of storage entries to return
