You'll want to set your SEPOLIA_RPC_URL
and PRIVATE_KEY
as environment variables. You can add them to a .env
file.
PRIVATE_KEY
: The private key of your account (like from metamask). NOTE: FOR DEVELOPMENT, PLEASE USE A KEY THAT DOESN'T HAVE ANY REAL FUNDS ASSOCIATED WITH IT.- You can learn how to export it here.
SEPOLIA_RPC_URL
: This is url of the sepolia testnet node you're working with. You can get setup with one for free from Alchemy
Optionally, add your ETHERSCAN_API_KEY
if you want to verify your contract on Etherscan.
Head over to faucets.chain.link and get some testnet ETH. You should see the ETH show up in your metamask.
make deploy ARGS="--network sepolia"
make fund ARGS="--network sepolia"
make withdraw ARGS="--network sepolia"
