Hydex — Privacy Suite for Crypto on Solana

Hydex Router — Private Withdrawals for SOL & SPL Tokens

Privacy-preserving router that lets users deposit into vaults and withdraw privately through a global pool system using Arcium MPC.

• Amount unlinkability — PRF-driven output shaping toward canonical k-values makes outputs statistically indistinguishable
• Destination privacy — withdrawal destinations are stored encrypted and revealed only within confidential compute
• Timing decorrelation — minimum residence time and epoch-batched withdrawals disrupt timing correlation
• Anonymity sets — shaping and sampling increase lookalike withdrawals and reduce unique fingerprints

Users cannot weaken their own privacy because privacy decisions are pushed into protocol logic rather than optional settings.

Hydex Bridge — Shielded Zcash to Solana Transfers

Converts Zcash shielded notes into wrapped sZEC on Solana while maintaining unlinkability, and supports shielded withdrawals back to Zcash.

• UFVK Enclave (TEE) — holds the Unified Full Viewing Key, generates unique Orchard Unified Addresses, and signs deposit attestations
• Arcium confidential compute — verifies enclave attestations and maintains encrypted burn intent state
• 2-of-3 FROST MPC quorum — threshold Orchard spending capability for withdrawals; full spending key is never reconstructed
• No single operator can unilaterally authorize a withdrawal — threshold security across enclave, MPC nodes, and on-chain program

hySOL — Encrypted Rewards on Solana

On-chain rewards program that manages epochs, snapshots user balances, harvests protocol fees, swaps assets, and finalizes epoch rewards for users to claim.

• Per-epoch state and ring buffer for efficient claims
• Permissionless harvest, swap, snapshot, and finalize instructions
• DEX routing through Meteora DLMM with Jupiter fallback
• Arcium-based VRF and mid-snapshot window support

Hydentity — Encrypted .sol Domain Identity

Vault identity and control system that pairs human-readable .sol domain identity and policy enforcement with encrypted configuration via Arcium MPC.

• Create vaults with explicit privacy and authorization policies
• Delegate operations without exposing sensitive configuration
• Encrypted policy enforcement via Arcium circuits — never plaintext on-chain
• TypeScript SDK for client abstraction and transaction building

What Hydex Delivers

• Default privacy — privacy is enforced at the protocol level, not optional per-transaction
• Separation of trust — compromising any single layer does not break privacy or correctness
• Arcium MPC — multi-party computation handles sensitive operations without exposing private data
• Solana-native — all products are built for Solana's on-chain architecture

Frequently Asked Questions

What is Hydex?

Hydex is a privacy suite for Solana that provides default, protocol-level privacy for token transfers, cross-chain bridging, staking rewards, and identity management using Arcium MPC confidential compute.

What data is public vs encrypted?

On-chain program state and transaction structure are public. Withdrawal destinations, policy configurations, bridge attestation details, and reward snapshots are encrypted via Arcium MPC. Users never need to expose private data to use Hydex protocols.

How does Hydex Router differ from a mixer?

Hydex Router is not a mixer. It is a protocol-level privacy layer that shapes outputs into canonical values, batches withdrawals by epoch, and encrypts destinations — making privacy the default rather than an opt-in feature.
