Important
The cast index-erc7201 feature has been integrated into Foundry. Please make use of this feature.
This utility repository provides tools for calculating storage locations according to the ERC-7201 standard for Ethereum smart contracts.
This ERC is proposed to enable developers to efficiently manage storage conflict risks during upgrades and other changes by calculating storage slots themselves, rather than relying on the compiler to determine them.
The utility facilitates easy and accurate storage location calculations, streamlining the development process for Ethereum blockchain applications.
-
Open your terminal.
-
Navigate to the directory where the
calc-storage-location.shscript is located. -
Run the script by entering the following command, replacing with the seed name for your storage location:
sh calc-storage-location.sh <name>
For example, if your seed name is "example.main", you would enter:
sh calc-storage-location.sh example.main
The script will calculate and output the corresponding storage location, which you can then use in your smart contract development to explicitly define storage slots, helping to manage storage conflict risks efficiently.
