(1)First, please confirm that the exchange has reviewed your request and issued the transaction. If the exchange did not issue a transaction, please contact the exchange to resolve the problem.
(2) It is recommended that you search the transaction information on the https://tokenview.com .
(3) Although some exchanges indicate the success of the transaction, it only means that the transaction information has been sent to the chain. The miners need to pack next and the transaction can be deemed to be successful only after miners have packed successfully and confirmed the transaction. If the exchange determines that the transaction has been typed, but no information about the transaction has been found on the Tokenview, then that means that the miners have not yet packaged the transaction.
(4) if it has been a long time since the exchange issued the currency and no information about the transaction can be found on the Tokenview, then it is possible that the transaction has been abandoned. Please contact the exchange or third-party issuer immediately to resend the transaction.
