Does a wholesale transaction get recorded on the registry?

Hello all,

Random questions. If I research an investment company, or even an individual. If they perform a transaction involving a wholesale where they are the one who "got the property under contract" then reassigned the sale to another purchaser, is there anything that I will see resulting in the wholesaler's name in the registry of deeds? For instance if John Smith had a direct mailing campaign and put a property under contract from Jane, then assigned the contract to an investor Tom. If I searched John smith's name in the registry of deeds, would I see any type of entrance or proof of this wholesale that ties his name in the recordings?

Thank you in advance.
