For contract addresses, you can look up the contents of an arbitrary storage location.
Usage:
> ethContractStorageLookup <contract-address-hex-alias-or-ens> <storage-slot> [optional-blocknumber-decimal-hex-or-earliest|latest|pending]
Looks up the value at a slot in a deployed contract’s storage.
Storage slots can be specified as ints (decimal or hex), but there are some special named storage slots. Use tab completion to check those out.
If no block number is explicitly supplied, storage as of the latest block will be checked.
Example:
> ethContractStorageLookup AaveLendingPoolV2-Proxy <tab>
; eip-1967:admin eip-1967:beacon eip-1967:logic
> ethContractStorageLookup AaveLendingPoolV2-Proxy eip-1967:logic
