I have a requirement where the bal. hold in customer wallet need to transfer to some cold wallet address. So far what I know i can do this in two ways.
Loop through customer address and transfer to cold wallet. This will charge me every time i do transfer
Transfer the despot amount from customer wallet to admin hot wallet address and the end of the day transfer from admin hot wallet to cold wallet. Again this will charge me every time I do transfer from the customer to admin hot waller address and then to cold wallet.
Please suggest how to solve this in an efficient way?
