forge-slots-inspect

Contains forge helper scripts to read onchain state variables by inspecting contract slots via foundry.

It allows to inspect (private) contract variables such as

• Arrays
• Mappings
• String

Examples / Usage

Arrays

function run(address targetContract, uint256 startSlot)

forge script script/Array.s.sol --sig "run(address,uint256)" 0xae33C49279cf0848dde5f92A2784a0aBA9395FA0 24 --rpc-url https://rpc.esync.network

Mappings

Load a value from a mapping for a particular key (e.g. ERC 20 token balance for an address).

function run(address targetContract, uint256 startSlot, address key)

forge script script/Mapping.s.sol:MappingScript --sig "run(address,uint256,address)" 0xae33C49279cf0848dde5f92A2784a0aBA9395FA0 11 0x1D64ec1f5b1fdC4373C3322394cf623C86792Ac7 --rpc-url https://rpc.esync.network

Strings

function run(address targetContract, uint256 startSlot)

forge script script/String.s.sol --sig "run(address,uint256)" 0xae33C49279cf0848dde5f92A2784a0aBA9395FA0 6 --rpc-url https://rpc.esync.network
