Im looking to make a small website with some different actions in a "company". This is based on a blockchain and at the moment you can enter an address and then do the action. I would like to do it such that you not only have to enter your address but also the secret key belonging to that address or something similar, is there a way to do that? Thank you in advance

You can create a login based on a Ethereum wallet signing a message.

See the tutorial One-click Login with Blockchain: A MetaMask Tutorial.

  • But using this would result in everybody on my private chain needing the metamask extension right? Commented Mar 24, 2021 at 9:15
  • You can do a eth_sign JSON-RPC with any wallet. You need to have a wallet for your blockchain in the first place. Commented Mar 24, 2021 at 12:07
