pendingin a mempool, onchainin a block, or rolledback from a block. Capturing these state transitions in real-time is challenging and can lead to corrupted data in your application.

Transaction Monitoring & Webhook Notification System
Maestro’s Transaction Manager is a state-of-the-art tool that abstracts away the complexity of managing blockchain transaction states. It provides a transaction monitoring dashboard and webhook notification system to track all transactions submitted with Maestro. This provides applications with the following benefits:1. On-submit transaction information
- Automatic Retries: Transactions that fail due to network issues are automatically resubmitted.
- Rejection Error Parsing: Transactions rejected by the node will return specific error messages, such as missing UTxOs or malformed transaction bodies.
- Pending Transaction State: Successfully submitted transactions are classified as
Pendingwhen entered into the mempool.
2. On-chain webhook notifications
- Onchain: Once a
Pendingtransaction is included in a block, an Onchain webhook notification is sent. - Rolledback: If an
Onchaintransaction is dropped due to a rollback, aRollbackwebhook notification is sent. - Timeouts: [Coming Soon] A transaction that remains in the mempool beyond its time-to-live will be marked as timed out and rejected.
Transaction State Machine
Transaction state transitions can best be understood with a state machine diagram.
Note: The state machine contains loops, meaning a transaction can transition through the same state multiple times before reaching an end state.
Onchain -> Rollback -> Onchain
Transaction Submission
All transactions submitted via Maestro’s specialized endpoint are recorded and tracked by the Transaction Manager. Below are the possible response codes:| Response Code | Description | State Transition |
|---|---|---|
| 200 | Valid submission | Start —> Pending |
| 400 | Invalid submission | Start —> Rejected |
| 500 | Network failure | Start —> Start (retry) —> Failed |
Common Use Cases
Webhooks are ideal for tracking continuously changing states of data, such as blockchain transactions. Maestro’s transaction notification system provides an efficient way for applications to react to on-chain events, enhancing user experience—particularly for time-sensitive applications.Examples of time-sensitive Web3 applications
- Submitting a trade on a DEX
- Placing a bid for an NFT auction
