Answer: If Kukai and tzkt.io both show that the transaction is confirmed, then the issue likely lies with Binance. It is possible that Binance has not yet updated their system to reflect the transaction, and so it is not showing up in your account. To ensure that the transaction goes through, you should contact Binance customer support to ask them to check their system and confirm the transaction. If the transaction is confirmed, they should be able to update their system to reflect this.
