// The confirmation screen's warning for a recipient that has never sent a
// transaction (https://git.eeqj.de/sneak/AutistMask/issues/528).

// The node's transaction count for an address is the number of transactions
// it has sent, so an address that only ever receives, such as a savings
// address or an exchange deposit address, has a count of zero. The warning
// used to fire on that count alone. It now also needs a zero balance: ETH an
// address received stays in its balance until it sends a transaction.
