You now need to add all your XRP wallet addresses to each of your exchange accounts to allow sends/withdrawals of crypto from and to your wallets.
For example, if you have accounts with Xago, VALR, LUNO, and Kraken, you will need to enter three XRP wallet addresses into each of these exchange accounts.
To further illustrate this, in Xago, you will add your VALR, Luno and Kraken XRP wallet addresses as beneficiaries.
This setup enables automated trading, seamless fund transfers/withdrawals, and the ability to send XRP between all your exchange accounts efficiently.
