You have 3 options.
- Create your own bitcoin client that connects to peers and monitors all transactions and blocks to notify you of any new UTXO
- Use an existing bitcoin client (such as Bitcoin Core) to connect to peers and monitor all transactions and blocks to notify you of any new UTXO
- Use a service (such as blockchain.info) that that connects to peers and monitors all transactions and blocks and which provides an API for you to be notified of any new UTXO

I plan to monitor the mempool by bitcoin-core to get new incoming tx of my addresses set
