We have a centralized wallet. How is it possible to send from one wallet to several others, in one transaction, that is, using one commission.
Question about ETH.
Here's the answer
https://multisender.app/https://bulksender.app/that platform will let you to send from one address to the a lot of address at the same time used one commission but you must remember that if the commission or fees will be combined by all of transactions that happened.
Like when you will be doing 20 transactions and the fees that you must paid need to cover all of transactions. Using this kind of platform will not make you pay less fees but it will help you to send to the a lot of addreses at the same time.
