Foundry

Foundry is a blazing fast, portable and modular toolkit for Ethereum application development written in Rust.

Foundry consists of:

• Forge: Ethereum testing framework (like Truffle, Hardhat and DappTools).
• Cast: Swiss army knife for interacting with EVM smart contracts, sending transactions and getting chain data.
• Anvil: Local Ethereum node, akin to Ganache, Hardhat Network.
• Chisel: Fast, utilitarian, and verbose solidity REPL.

Install OpenZepplin's upgraddeable contracts

$ forge install OpenZeppelin/openzeppelin-contracts-upgradeable --no-commit

Install OpenZepplin's contracts

$ forge install OpenZeppelin/openzeppelin-contracts --no-commit

The --no-commit flag prevents the following error:

Error:
The target directory is a part of or on its own an already initialized git repository,
and it requires clean working and staging areas, including no untracked files.

Check the current git repository's status with `git status`.
Then, you can track files with `git add ...` and then commit them with `git commit`,
ignore them in the `.gitignore` file, or run this command again with the `--no-commit` flag.

If none of the previous steps worked, please open an issue at:
