Foundry Starter Kit

Foundry Starter Kit is a repo that shows developers how to quickly build, test, and deploy smart contracts with one of the fastest frameworks out there, foundry!

This repo is based on the femplate

You can also check out the similar dapptools-starter-kit

Installation

Requirements

• Git (version 2.36.1 or above)
• Foundry / Foundryup
• Nix

And you probably already have make installed... but if not try looking here.

Getting Started / Quickstart

git clone https://github.com/smartcontractkit/foundry-starter-kit.git
cd foundry-starter-kit
make # This installs the project's dependencies.
make test

Testing

make test

or

forge test

Deploying to a network

Deploying is done by a prompt system rather than a flexible single command to run at this time. If you'd like to contribute by writing some scripts to make deploying easier, please do!

Setup

You'll need the following:

• RPC URL: A URL to connect to the blockchain. You can get one for free from Alchemy.
• Private Key: A private key from your wallet. You can get a private key from a new Metamask account
  • Additionally, if you want to deploy to a testnet, you'll need test ETH and/or LINK. You can get them from faucets.chain.link.
• Constructor Arguments: These are the arguments that you pass to your smart contract on deployment. If you look at the constructor function in each contract, those are the values that they need. If you want some examples, we've provided some in our scripts/helper-config.sh file.
• Contract: The name of the contract you want to deploy, ie PriceFeedConsumer.

Deploying

bash scripts/deploy_<NETWORK>.sh

You'll be prompted for the following:

Enter Your Rinkeby RPC URL:
Example: https://eth-mainnet.alchemyapi.io/v2/XXXXXXXXXX

Which contract do you want to deploy (eg Greeter)?
Enter constructor arguments separated by spaces (eg 1 2 3):

compiling...
success.
Insert private key:
0x<PRIVATE_KEY_HERE>

Full Example:

bash scripts/deploy_rinkeby.sh

Enter Your Rinkeby RPC URL:
https://eth-rinkeby.alchemyapi.io/v2/XXXXXX

Which contract do you want to deploy (eg Greeter)?
PriceFeedConsumer

Enter constructor arguments separated by spaces (eg 1 2 3):
0x8A753747A1Fa494EC906cE90E9f37563A8AF630e

Insert private key:
0xXXXXXXX
