Tx-Trace

The Tx-Trace service allows traders to get an insight on transactions propagation by the BDN. 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.

The Tx-Trace utility has a built-in rate limiting defined by the account tier.

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"}
