Solidity Setup
For existing projects, detect the framework by looking for hardhat.config.* (Hardhat) or foundry.toml (Foundry). For new projects, ask the user which framework they prefer.
Hardhat Setup
- Initialize project (only if starting a new project)
npx hardhat init # Hardhat v2
npx hardhat --init # Hardhat v3
- Install OpenZeppelin Contracts:
npm install @openzeppelin/contracts
- If using upgradeable contracts, also install the upgradeable variant:
npm install @openzeppelin/contracts-upgradeable
Foundry Setup
- Install Foundry
curl -L https://foundry.paradigm.xyz | bash
foundryup
- Initialize project (only if starting a new project)
forge init my-project
cd my-project
- Add OpenZeppelin Contracts:
forge install OpenZeppelin/openzeppelin-contracts@v<VERSION>
- If using upgradeable contracts, also add the upgradeable variant:
forge install OpenZeppelin/openzeppelin-contracts-upgradeable@v<VERSION>
Look up the current version from https://github.com/OpenZeppelin/openzeppelin-contracts/releases. Pin to a release tag — without one,
forge installpulls the default branch, which may be unstable.
remappings.txt(if not using upgradeable contracts)
@openzeppelin/contracts/=lib/openzeppelin-contracts/contracts/
remappings.txt(if using upgradeable contracts)
@openzeppelin/contracts/=lib/openzeppelin-contracts-upgradeable/lib/openzeppelin-contracts/contracts/
@openzeppelin/contracts-upgradeable/=lib/openzeppelin-contracts-upgradeable/contracts/
Note The above remappings mean that both
@openzeppelin/contracts/(including proxy contracts) and@openzeppelin/contracts-upgradeable/come from theopenzeppelin-contracts-upgradeablesubmodule and its subdirectories, which includes its own transitive copy ofopenzeppelin-contractsof the same release version number. This format is needed for Etherscan verification to work. Particularly, any copies ofopenzeppelin-contractsthat are installed separately are NOT used.
Import Conventions
- Standard:
@openzeppelin/contracts/token/ERC20/ERC20.sol - Upgradeable:
@openzeppelin/contracts-upgradeable/token/ERC20/ERC20Upgradeable.sol - Use upgradeable variants only when deploying behind proxies; otherwise use standard contracts.
