Is there a Bitcoin Core method that identify when a transaction in the mempool uses Replace-By-Fee (RBF)?

I am trying to track transactions in the mempool that utilize Replace-By-Fee (RBF). My approach involves saving the current transactions in the mempool and comparing them to newly added transactions. If a new transaction shares inputs with a previously saved transaction, I infer that it replaced the original transaction via RBF. In such cases, I save both the original and the replacement transactions for further analysis.

My question is, if instead of doing all this, is there any method in which the Bitcoin core to tell me when a transaction has used RBF.

Bitcoin mining may be providing incremental support to the Russian ruble, Central Bank Governor Elvira Nabiullina said, while cautioning that the effect is difficult to measure because much of the sector still operates in a legal and reporting gray zone. Bitcoin Mining May Support The Ruble Responding to a question at a press conference, Nabiullina said it is “probably difficult to quantify” mining’s influence “because a significant part of mining is still in a gray area.” Still, she added that mining is “indeed one of the additional factors contributing to the strong ruble exchange rate.” As Russian business news portal for RBC reported , her remarks come as Russian officials increasingly frame mining and crypto flows as macro-relevant, not just a niche tech or energy story. Earlier, Maxim Oreshkin, deputy head of the presidential administration, said ruble forecasts have been thrown off by the underestimation of financial flows tied to mining and cryptocurrency. In his view, the s...
