A successful simulation is a result for a chosen state and execution environment, not a reservation in the next block. Keeping those two distinctions in your logs makes a missing bundle much easier to investigate.</p> <p>The <a href="https://docs.flashbots.net/flashbots-auction/advanced/troubleshooting">Flashbots troubleshooting guide</a> identifies several common causes: a transaction reverts, the incentive is insufficient, a competing bundle changes the opportunity, delivery is late, or the block producer does not use the relevant builder path. More than one can apply to the same attempt.</p> https://blazed.sh/blog/posts/missing-pending-transactions/ Sat, 05 Sep 2026 08:00:00 +0000 https://blazed.sh/blog/posts/missing-pending-transactions/ <p>Your subscription emits a transaction hash. You immediately request the transaction and get <code>null</code>. Or a transaction lands in a block, but its hash never appeared in your pending feed.</p> <p>Those symptoms are different. The first proves that your subscription delivered a particular hash but a later lookup could not resolve it. The second only proves that you did not record a pending notification. Neither, by itself, identifies replacement, eviction or private submission.</p>
