PRBContracts

Off-the-shelf Solidity smart contracts.

• Designed for Solidity >=0.8.4
• Uses custom errors instead of revert reason strings
• Complementary to OpenZeppelin's library
• Well-documented via NatSpec comments
• Thoroughly tested with Foundry

I initially created this library to streamline my personal workflow, as I was tired of having to maintain identical contracts across multiple repositories. However, if you find this library beneficial to your own projects, that's a win-win situation for both of us.

Install

Foundry

First, run the install step:

forge install --no-commit PaulRBerg/prb-contracts@v5

Your .gitmodules file should now contain the following entry:

[submodule "lib/prb-contracts"]
  branch = "v5"
  path = "lib/prb-contracts"
  url = "https://github.com/PaulRBerg/prb-contracts"

Finally, add this to your remappings.txt file:

@prb/contracts/=lib/prb-contracts/src/

Hardhat

pnpm add @prb/contracts

Usage

Once installed, you can use the contracts like this:

// SPDX-License-Identifier: MIT
pragma solidity >=0.8.4;

import { ERC20 } from "@prb/contracts/token/erc20/ERC20.sol";
import { ERC20Permit } from "@prb/contracts/token/erc20/ERC20Permit.sol";

contract MyToken is ERC20, ERC20Permit {
  constructor(string memory name_, string memory symbol_, uint8 decimals_) ERC20Permit(name_, symbol_, decimals_) {}
}

Pre Requisites

You will need the following software on your machine:

• Git
• Foundry
• Node.Js
• Pnpm

In addition, familiarity with Solidity is requisite.

Set Up

Clone this repository including submodules:

$ git clone --recurse-submodules -j8 git@github.com:PaulRBerg/prb-contracts.git

Then, inside the project's directory, run this to install the Node.js dependencies:

$ pnpm install

Now you can start making changes.

Syntax Highlighting

You will need the following VSCode extensions:

• hardhat-solidity
• vscode-tree-language

Security

While I have strict standards for code quality and test coverage, it's important to note that this project may not be entirely risk-free. Although I have taken measures to ensure the security of the contracts, they have not yet been audited by a third-party security researcher.

Caveat Emptor

Please be aware that this software is experimental and is provided on an "as is" and "as available" basis. I do not offer any warranties, and I cannot be held responsible for any direct or indirect loss resulting from the continued use of this codebase.
