cast storage [options] address slot


Get the raw value of a contract’s storage slot. (Slot locations greater than 18446744073709551615 (u64::MAX) should be given as hex. Use cast index to compute mapping slots.)

Emit the slot number to get the full storage layout (requires contract to be verified on Etherscan with a Solidity version > 0.6.5 or you must be in a Forge project with a local contract matching the deployed bytecode).

The address (address) can be an ENS name or an address.
