Prerequisites

Before you start monitoring transactions, make sure you have:
  • Created an Account
  • Created a Project
  • Access to the Transactions page on your Maestro dashboard.

​
Overview

The Transaction Manager & Monitoring System enables you to track the entire lifecycle of all transactions submitted via the Maestro API. Stay updated on each transaction’s status—from pending in the mempool, to being accepted on-chain, rejected by a node, or rolled back by the network. Real-time state change notifications are available via Webhooks created on the platform Transaction page.
