Do I need to enter a tag/memo for transactions?
Tag/Memo is mostly used in sending cryptocurriencies to Centralized Exchanges.
Tag/Memo is not required for transactions between private wallets, such as CoolWallet. However, exchanges with a large client base may require destination tags/memos for payments to identify which customer the payment is for. If the exchange in which you are sending assets mandates a tag/memo for outgoing transactions, you can simply enter any number from 1-9 to your CoolWallet.
