# Using Chainlink data feeds with Foundry
This project shows how to use Foundry to compile and deploy Smart contracts.
See the full tutorial on the Chainstack blog:
* [Using Chainlink data feeds with Foundry](https://chainstack.com/using-chainlink-data-feeds-with-foundry/)
## Project details
Foundry is one of the latest smart contract development tools currently in the market, and it allows users to compile contracts, write tests, deploy contracts, and much more through its command line interface. This project is already set up for you to deploy smart contracts and interact with Chainlink’s data feeds.

## Quick start
Clone this repository.
### Install Foundry
```sh
curl -L https://foundry.paradigm.xyz | bash
```
Then:
```sh
foundryup
```
### Compile smart contracts
```sh
forge build
```
### Create a .env file
In the root directory:
```sh
touch .env
```
This will create a new `.env` file, paste and edit the following in it:
```env
GOERLI_RPC_URL=CHAINSTACK_GOERLI_NODE_URL
PRIVATE_KEY=YOU_PRIVATE_KEY
ETHERSCAN_KEY=ETHERSCAN_API_KEY(to verify the smart contract)
```
### Deploy the smart contract
Run the following command:
```sh
forge script script/priceFeedsScript.s.sol:ChainlinkScript --rpc-url $GOERLI_RPC_URL --private-key $PRIVATE_KEY --broadcast --verify --etherscan-api-key $ETHERSCAN_KEY -vvvv
```
## Prerequisites
* Linux or MacOS
* A Goerli Chainstack endpoint
Deploy a Goerli node:
1. [Sign up with Chainstack](https://console.chainstack.com/user/account/create).
1. [Deploy a node](https://docs.chainstack.com/platform/join-a-public-network).
1. [View node access and credentials](https://docs.chainstack.com/platform/view-node-access-and-credentials).
## Dependencies
* [Foundry toolkit](https://github.com/foundry-rs/foundry)
## Install
Clone this repository.
Install Foundry
```sh
curl -L https://foundry.paradigm.xyz | bash
```
Then:
```sh
foundryup
```
## Example
Here is a link to a verified smart contract deployed to the Goerli testnet, and then verified using Foundry's command line.
