I'm creating a tipping type app where I issue unique monero private keys for all my users like how an exchange has a different monero address for each user. I'm sure they are just using a payment id for each user while all funds goto the same wallet.
But in my case, I'm not using a payment ID. How can I sweep all coins from these addresses to my own without a rescan of the blockchain for each address? FYI, I also have a copy of the private keys for my users.
- Scanning for an updated balance takes awhile. Can this be skipped?
