The TRONZ privacy protocol uses a Bitcoin-like UTXO model. The balance of the shielded address exists in the note. Each transaction consumes the note generated by the previous transaction, and then generates a new note. The balance of the shielded address is all the unspent note collections belonging to the address. .
Due to the current restrictions of the TRONZ privacy agreement, only one note can be transferred in a transaction, which also limits the maximum number of single transfers you can make, that is, the single limit = the maximum denomination of the note you hold - fee . If you want to transfer more tokens, you need to make multiple transfers. If the denomination of note is too small (less than single transfer fee), it may not be possible to transfer.
You can click on the token in your shielded address and click on the details under the balance to enter the note details to see the notes you have and their denomination.
Shielded transactions are currently only available on the Nile Testnet. You can connect to the Nile Testnet by selecting the Nile version in the Settings - Switch between versions or adding the Nile Test Node in Settings - Node Settings.
