Ethereum: mismatch of Foundry library dependencies

As a developer working on custom decentralized applications (dApps), you often run into library dependency issues. One common problem that can arise is a mismatch between the Foundry libraries and the dependencies required by your dApp.

In this article, we’ll look at a problem you encountered with OpenZeppelin v4 and the UniswapV3 peripheral/core, two critical components of your project. We’ll also discuss how to resolve this dependency mismatch using Foundry’s library management tools.

Problem

Ethereum: Foundry library dependency mismatch

When you installed the UniswapV3 peripheral/core in your project, it introduced a new library dependency on OpenZeppelin v4. However, OpenZeppelin v4 is no longer supported by the project developers due to security vulnerabilities and changes in its core functions.

As a result, when you try to import the OpenZeppelin v4 libraries into your dApp, you encounter errors and warnings from the Foundry tools. This mismatch can cause your code to fail to compile or run in an unstable state.

Solution

To resolve this dependency mismatch, follow these steps:

  • Check your dependencies

    : run npm ls or yarn list to make sure all required libraries are installed correctly.

  • Update OpenZeppelin v4: If the developers have released a new version of OpenZeppelin v4, update your project by installing the latest version using npm or yarn:

npm install --save @openzeppelin/contracts

Alternatively, you can use yarn add with the --force-standard option to force the latest version:

yarn add @openzeppelin/contracts --force-standard

  • Update UniswapV3 peripheral/kernel: Run npm uninstall or yarn remove to remove the outdated UniswapV3 peripheral/kernel dependency, then install the new version using npm or yarn:

npm uninstall uniswap-v3-periphery/core
npm install --save @uniswap/v3-periphery

As alternatively you can use yarn add with the --force-standard option:

yarn add @uniswap/v3-periphery --force-standard

  • Update OpenZeppelin v4 Libraries: After updating dependencies to include OpenZeppelin v4, run npm install or yarn install to update all affected libraries.

Recommendations

To prevent this problem in the future:

  • Check regularly for library updates and companion releases.
  • Use Foundry’s built-in dependency management tools to ensure library version accuracy.
  • Thoroughly test your dApp after updating dependencies to catch any issues early.

By following these steps, you will be able to resolve the Foundry library dependency mismatch caused by the OpenZeppelin v4 and UniswapV3 peripherals/core. Happy coding!
