Tx-Trace

The Tx-Trace service allows users to check the status of a submitted transaction — whether it was included on-chain, or how it behaved within bloXroute’s internal system.

With the Tx-Trace utility you can know if a transaction was private or public, what region received it first, and the timestamp each region saw it. Traders can optimize their trading bot and infrastructure to minimize latency and processing time.

For each region, Tx-Trace will return the timestamp the transaction was processed and the time difference from the first region to process it.

Tx-Trace data is available only for a few hours. In case the data has been purged, the following will be displayed (this message will also be displayed for private transactions):

{"message":"received no info about transaction <TX hash> from relays"}

This endpoint is available with a limit of 20 requests per day.

Purchase the Tx Trace Add-on to increase the limit to 500 requests per day.
