Shielded transactions are fully shielded using zero-knowledge proofs or zk-SNARK ( Zero-Knowledge Succinct Non-Interactive Argument of Knowledge ).
Shielded transactions completely hide and encrypt transaction information - the receiver, the sender, the amount, or any other data - and the encryption is off-chain so no one can find or analyse the transaction.
Shielded transactions are :
Safe and Reliable, Instant Transfer, Total Privacy Control and Untraceable
