Where can I get a list of stale RBF'd transactions? I would like to prove that a certain transaction was in the mempool on a certain date before it got replaced via RBF with another transaction. Is there any service that provides this data?
I would like to prove that a certain transaction was in the mempool on a certain date before it got replaced via RBF with another transaction.

Consider Tx de8ba282831c6d645aa777a35a5b9f2107cbd96913a9cd4c5880420db092e399 as an example.

I am not sure but maybe this information is only available for transactions that belong to your wallet.

Is there any service that provides this data?

Couldn't find such information in any of the famous bitcoin explorers. Best I could find was one explorer that shows invalid type for tx which got replaced:
