Off-the-shelf Solidity smart contracts.
- Designed for Solidity >=0.8.4
- Uses custom errors instead of revert reason strings
- Complementary to OpenZeppelin Contracts
- Promotes PRBMath as a fixed-point math library for Solidity
- Well-documented via NatSpec comments
- Thoroughly tested with Foundry
I created this library for my own use, to avoid having to maintain the same contracts in different repositories. If you find it useful too, that's a win-win.
First, run the install step:
forge install --no-commit paulrberg/prb-contractsThen, add the following line to your remappings.txt file:
@prb/contracts/=lib/prb-contracts/src/
yarn add @prb/contractsOnce installed, you can use the contracts like this:
// SPDX-License-Identifier: Unlicense
pragma solidity >=0.8.4;
import "@prb/contracts/token/erc20/ERC20.sol";
import "@prb/contracts/token/erc20/ERC20Permit.sol";
contract MyToken is ERC20, ERC20Permit {
constructor(
string memory name_,
string memory symbol_,
uint8 decimals_
) ERC20Permit(name_, symbol_, decimals_) {}
}
Feel free to dive in! Open an issue, start a discussion or submit a PR.
You will need the following software on your machine:
In addition, familiarity with Solidity is requisite.
Clone this repository including submodules:
$ git clone --recurse-submodules -j8 git@github.com:paulrberg/prb-contracts.gitThen, inside the project's directory, run this to install the Node.js dependencies:
$ yarn installNow you can start making changes.
You will need the following VSCode extensions:
While I set a high bar for code quality and test coverage, you shouldn't assume that this project is completely safe to use. The contracts have not been audited by a security researcher.
This is experimental software and is provided on an "as is" and "as available" basis. I do not give any warranties and will not be liable for any loss, direct or indirect through continued use of this codebase.
If you discover any security issues, please contact me via Keybase.
