ape-hardhat: Ape network provider for Hardhat

Quick Start

Hardhat network provider plugin for Ape. Hardhat is a development framework written in Node.js for Ethereum that includes a local network implementation.

Dependencies

• python3 version 3.8 or greater, python3-dev
• Node.js, NPM, and Hardhat 2.12.0 or greater. See Hardhat's Installation documentation for steps.

Installation

via pip

You can install the latest release via pip:

pip install ape-hardhat

via setuptools

You can clone the repository and use setuptools for the most up-to-date version:

git clone https://github.com/ApeWorX/ape-hardhat.git
cd ape-hardhat
python3 setup.py install

Quick Usage

To use the plugin, first install Hardhat locally into your Ape project directory:

cd your-ape-project
npm install --save-dev hardhat

After that, you can use the --network ethereum:local:hardhat command line flag to use the hardhat network (if it's not already configured as the default).

This network provider takes additional Hardhat-specific configuration options. To use them, add these configs in your project's ape-config.yaml:

hardhat:
  port: 8555

To select a random port, use a value of "auto":

hardhat:
  port: auto

This is useful for multiprocessing and starting up multiple providers.

You can also adjust the request timeout setting:

hardhat:
  request_timeout: 20  # Defaults to 30
  fork_request_timeout: 600  # Defaults to 300

Mainnet Fork

The ape-hardhat plugin also includes a mainnet fork provider. It requires using another provider that has access to mainnet.

Use it in most commands like this:

ape console --network :mainnet-fork:hardhat

Specify the upstream archive-data provider in your ape-config.yaml:

hardhat:
  fork:
    ethereum:
      mainnet:
        upstream_provider: alchemy

Otherwise, it defaults to the default mainnet provider plugin. You can also specify a block_number.

NOTE: Make sure you have the upstream provider plugin installed for ape.

Hardhat deployments are disabled for forks for performance reasons. If you want your contract deployments to run on your fork, you can set enable_hardhat_deployments to true in your config:

hardhat:
  fork:
    ethereum:
      mainnet:
        upstream_provider: alchemy
        enable_hardhat_deployments: true

ape plugins install alchemy
