No, the transactional metadata are not part of the ledger state.

Thanks for the reply. Then, is there a way to scan the ledger directly? Are any of the db-* binaries in the tarball able to this? I need something that doesn't require 40GB of RAM, so db-sync is not an option. And it also needs to be able to run independently, without external services. My last resort would be Carp.

Sadly, I do not think that information is stored anywhere by the cardano-node. Cardano-db-sync or tools like Blockfrost actually has to reply all the blocks to extract it. Try maybe looking at Kupo.

I didn't know Kupo, looks great. That could be a useful tool. In the meantime, I've been considering other approaches to make it work with db-sync and even Blockfrost. Thanks again!
