The chainstate db contains basically two parts, the UTXO set and the actual chain state. The stuff pertaining to the UTXO set is in txbd.{cpp, h}. The stuff related to the actual chain state can be found in validation.{cpp, h} (mostly things under the CChainState class).

i am interested in UTXO set .
