I started my first blockchain tuto which is:

I am trying to deploy a NFT in the Rinkeby testnet with hardhat. Here are the steps I have done to config my environment:

  • Installed Hardhat

  • add the following env variable in my .zshrc (RINKEBY_RPC_URL, PRIVATE_KEY, MAINNET_RPC_URL)

  • Created a account with infuria to get my RINKEBY_RPC_URL:'https://rinkeby.infura.io/v3/My_Project_Id'

  • Add my PRIVATE_KEY from my Metamask

  • Create an account on https://www.alchemy.com/ to get my MAINNET_RPC_URL: 'https://eth-mainnet.alchemyapi.io/v2/My_Project_Id'

  • I used https://faucet.rinkeby.io/ to get Ether on my metamask (Rinkeby testnet). Same thing with LINK

Then when I want to deploy my first NFT using hardhat -> hh deploy --network rinkeby

I have this error:

Error message says:

insufficient funds for intrinsic transaction cost

Which is weird as I have added few Eth and link on the Rinkeby testnet. Did I missed something?
