Hello, I will soon buy a business related to crypto-currency. The business receives the money in ETH on an ERC-20 wallet, so the owner will give me the private keys to receive the money. The concern being: I can't change the private key...log into the wallet and take the money. I can't change the wallet to receive the money either, because it is written in the smart contract. In short, the only solution is that a script ? A program? A new smart contract? Could automatically transfer the ETH from the initial wallet to a new wallet that I would have created (which, this time, will belong to me entirely). I don't know if I need a solidity expert for this or if it's feasible in another way! Please contact me with an ETA, a fixed price and a explanation how you w...
