I have a simple web3.js based app and like to call a method from an contract.
For this method an authenticaten is needed. I found some examples in the web using web3.eth.accounts.signTransaction
But in this case, I need the private key.
Waht I need is something like web3.eth.personal.unlockAccount
, which unlock the account not for an time range, but for the transaction only.
Is this possible?
