Simple NFT Auction

Setup

Install foundryup if you don't already have it:

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

Restart terminal or reload PATH env variable. Where this is stored will depend on your machine. The installation above will show your correct path. E.g:

source ~/.bashrc

run foundryup. This will install forge, cast, and other related binaries:

foundryup

More information on can be found in the Foundry Book: https://book.getfoundry.sh/getting-started/installation

Clone repo:

git clone https://github.com/lukmaan-k/simple-nft-auction.git

cd into the newly cloned directory and install dependencies:

forge install

Tests

Run unit tests with:

forge test

Deployment

First rename .env.example to .env and use this to store your environment vars. The existing PRIVATE_KEY is a test account loaded with some SepoliaETH. PRIVATE_KEY_ANVIL is the first local test account provided by anvil (the local blockchain). You will need to fill in your own endpoint for Sepolia and an etherscan key if you also want to verify the contract (see below).

To deploy locally, first start a local node by running:

anvil

Run deployment script with:

forge script script/Deploy.s.sol:Deploy --rpc-url http://localhost:8545 --broadcast

To deploy to a testnet, change line 10 in script/Deploy.s.sol to use PRIVATE_KEY instead of PRIVATE_KEY_ANVIL

Now load the variables in the .env file with:

source .env

Deploy with with:

forge script script/Deploy.s.sol:Deploy --rpc-url $SEPOLIA_RPC_URL --broadcast

Or to also verify contracts when deploying, run:

forge script script/Deploy.s.sol:Deploy --rpc-url $SEPOLIA_RPC_URL --broadcast --verify --etherscan-api-key $ETHERSCAN_KEY

All of the forge commands above (except forge install) can have a -vvvv flag added at the end for a more verbose output
