Why my TRX transaction failed?
Note that addresses on TRON Blockchain are categorized into "Active" & "Inactive" addresses. Activating an address may require an additional fee.
Dear CoolWallet Users,
On the TRON network, an account creation fee" (1.1 TRX for now) is required when users transfer TRX to a newly-created account. If this scenario applies to you, kindly reserve 1.1 TRX in your wallet instead of sending the maximum amount.
