Hardhat Dependency Injector

Copy compiled Solidity bytecode directly from the NPM dependencies.

Based on the Hardhat Dependency Compiler by Nick Barry

Problem / Motivation

Some Solidity npm packages provide already compiled smart contracts; some of these packages don't provide Solidity sources (for example Uniswap smart contracts); in many cases sources are not required, compiled versions are enough (for example in tests); in some cases already compiled contracts are required (for example when deploying Uniswap v2 infrastructure for testing purposes the exact match of the bytecode is required, which is possible to achieve only when using already compiled contracts)

Installation

npm install --save-dev hardhat-dependency-injector
# or
yarn add --dev hardhat-dependency-injector

Usage

Load plugin in the Hardhat config:

require("hardhat-dependency-injector");

Add configuration under the dependencyInjector key:

option	description	default
paths	Array of compiled dependency paths to copy	[]

dependencyInjector: {
    paths: [
        "@uniswap/v3-core/artifacts/contracts",
        "@uniswap/v3-periphery/artifacts/contracts",
    ],
}
