@thesatoshicompany/optimism-openzeppelin-compat v1.0.3

optimism-openzeppelin-compat

This repo contains patches needed to use the OpenZeppelin contracts with Optimism L2.

Example: When using Optimism ETH is not supported and instead WETH must be used. When using OpenZeppelin Address contract via ERC20, there are balance checks for ETH and thus the compilation fails due to an unsupported OPCODE. This patches these issues and allows for seamless development.

Installation

Use the following command to install:

npm i --save @thesatoshicompany/optimism-openzeppelin-compat

Add the following to the package.json scripts section:

"scripts": {
+ "postinstall": "patch-package --patch-dir node_modules/@thesatoshicompany/optimism-openzeppelin-compat/patches"
},

Note: Post install script is needed because this package does not patch files on install automatically. It only provides the appropriate patches and the needed module to apply them.

This was a design choice so full control is left to the consumer of the module for if and when they are applied.

Supported OpenZeppelin Versions
