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

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.

Clone this repository.

curl -L https://foundry.paradigm.xyz | bash

Then:

foundryup

forge build

In the root directory:

touch .env

This will create a new .env file, paste and edit the following in it:

GOERLI_RPC_URL=CHAINSTACK_GOERLI_NODE_URL
PRIVATE_KEY=YOU_PRIVATE_KEY
ETHERSCAN_KEY=ETHERSCAN_API_KEY(to verify the smart contract)

Run the following command:

forge script script/priceFeedsScript.s.sol:ChainlinkScript --rpc-url $GOERLI_RPC_URL  --private-key $PRIVATE_KEY --broadcast --verify --etherscan-api-key $ETHERSCAN_KEY -vvvv
