I may have to update changeset as the checks do not recognize any changeset, also I may have to cross-verify the code and add or updates test suites for the proposed changes @Legend101Zz .

Hi @Legend101Zz please review the changes made to the files - utxoReconstruction.ts and utxo.ts , I have not made any changes to the tests as I did not fully understood the explanation for creating an actual RBF transaction locally.

Thanks for the PR , I'll start looking into it in depth once you move from draft PR , I'll wait for that , until then I'd say that package-lock.json changes should not happen here as there was no package changes involved :)

Sorry sir changes made to the package-lock.json file went unnoticed, it will lead to major problems later on if left unchecked, let me take care of them first.

Sir @Legend101Zz please review the changes now, I am more confident now and so converting draft to PR.
