I'm making a Dapp for users who don't have a wallet installed and have no ETH address. I would like users to use my account for all transactions.
I'd like to sign my transactions with the contract owner address using his private key.
But I can't find a way to doing that. Please gimme some help
I'm using firstname.lastname@example.org (web3.js) For the moment, my contract is deployed throw the Ropsten Testnet
