* NSDL and CSDL depositories keep records of various financial securities: Shares, Bonds, Mutual funds etc. in dematerialized (DEMAT) format, in other words in an electronic format. You cannot directly access these depositories, you need an intermediary and they are called Depository Participants (DP), these are the entities which transact on your behalf with the Depositories and make sure every time you buy or sell your shares, it’s recorded with the depository. Usually, the brokerage firm also happens to be a DP, if they are not, they may use the services of an existing DP. For instance, in the past Zerodha used to use the services of IL&FS which in turn was registered with both NSDL and CDSL the two depositories, now Zerodha is itself registered as Depository participants (DP) with CDSL and hence does not need an intermediary like IL&FS. - Capital Mind
