<p>Title..  Hoping to find out when a historical tx went into the mempool.  I'm aware this is transient data and not in the blockchain.  However i'm pretty sure I remember in the old days explorers used to log it.</p>
<p>edit:</p>
<p>i would like to find a block explorer that logs the first time its node saw particular transactions in the mempool, as opposed to the first time they were in a block.   ie:  I would like to look up a tx and see how long it sat in the mempool before it was mined.</p>

The closest thing i know of is https://mempool.observer/monitor/ but i don't think they store the first seen version of an RBFed tx.

From my recollection: For transaction in the mempool, a timestamp in a block explorer is set to when the transaction was first observed; once the transaction is mined, the timestamp is changed to the timestamp of the block.

Are there any Bitcoin block explorers still around that log First Seen by node data?
