Getting started with hardhat and react

1. start react app: cd client npm start

2. start local test bc from hardhat (use another terminal) cd blockchain (maybe you need to install hardhat ethers and waffle beforehand) npx hardhat node

3. deploy greeter to your local bc (use another terminal) npx hardhat run scripts/deploy.js --network localhost

4. install MetaMask (please use a chromium browser) and import an Account from your local bc -> use a copy of one of the private keys from your local test blockchain to

1. Nonce too high. Expected nonce to be 0 but got 19. Note that transactions can't be queued when automining. -> Maybe you restarted your Blockchain? In this case, your Blockchain expect that the nonce is 0 -> go to metamask settings and change manual the nonce

2. Calling an Account which is not a contract -> Could be false contract address in component -> redeploy the contract -> npx hardhat run scripts/deploy.js --network localhost -> double check the contract address
