## Overview

Token-2022 confidential transfers are live on mainnet, using ElGamal encryption with an optional auditor key. Amounts are hidden while addresses stay public. Arcium's MPC network and the Umbra wallet built on it add shielded transfers on top. The gap is adoption: proof generation still needs Rust backends, which keeps the feature ahead of the wallets that would use it.
