A Ripple (XRP) "account delete" transactions transfer the native balance (the whole amount of XRP an account holds) to another account and removes the source account from the ledger.
Operations such as "account delete" are not considered as deposits. We only support "Payment operation" for XRM deposits.
To avoid unsupported "account delete" transactions, we recommend leaving min of 5 XRP in your sending account.
Please note that using this option to transfer XRP to your Nexo account might result in your funds being unrecoverable.
