Block Monitor crawls the blockchain on a scheduled interval, which is based on the blocktime of the particular blockchain it is crawling at the time. As a result, users can expect to receive a push notification within the time it would take for one or two confirmations, accounting for potential overlap and blockchain variances.

Every blockchain is different, and there may be times where a transaction is delayed, or an upstream API is outdated, which could result in further notifcation delays.
