# What is Hydex?

Hydex is a non‑custodial, privacy‑preserving bridge connecting the Zcash Orchard shielded pool to the Solana blockchain. It enables:

* Shielded ZEC deposits → Shielded Wrapped ZEC (sZEC) on Solana
* sZEC burns → Shielded ZEC withdrawals

Hydex ensures:

* No deposit/withdrawal linkage
* No leakage of Zcash metadata
* No requirement to reveal view keys or spending keys
