H33 SHIELD FOR SOLANA

Solana uses Ed25519.
Ed25519 is quantum-dead.
We fixed that.

The first post-quantum privacy layer for Solana. Dilithium-signed transactions that survive quantum computers. FHE-encrypted on-chain data that programs compute on without reading. ZK-STARK proofs verified in your program.

The problem

Every Solana transaction is quantum-vulnerable. Every account is plaintext.

SOLANA TODAY
Signatures: Ed25519 (quantum-dead)
Account data: Plaintext (readable by anyone)
Computation: On plaintext data
Privacy: Zero (full blockchain transparency)
Quantum timeline: 2030-2035 (Shor's algorithm)
Harvest now, decrypt later: Already happening
SOLANA + H33 SHIELD
Signatures: Ed25519 + Dilithium-5 (quantum-proof)
Account data: FHE ciphertext (unreadable noise)
Computation: On encrypted data (homomorphic)
Privacy: Full (data never exposed)
Quantum timeline: Irrelevant (lattice-based)
Harvest attack: Yields noise
Capabilities

Three layers. One SDK. Every Solana program.

🔒
Quantum-Proof Signatures
Nested hybrid: Ed25519 + Dilithium-5. Your transaction has two signatures — one classical (for Solana compatibility) and one post-quantum (for 30-year security). If quantum breaks Ed25519, Dilithium stands.
🧮
Encrypted Accounts (FHE)
Store account data as BFV ciphertext. Your Solana program computes on encrypted data — additions, multiplications, comparisons — without ever decrypting. A validator compromise yields noise.
✅
ZK-STARK On-Chain Verification
Prove computation correctness without revealing inputs. 192-byte proofs verified in your program at 0.2 microseconds. No trusted setup. Transparent arguments of knowledge.
💰
Private DeFi
Encrypted order books. Hidden swap amounts. Private lending positions. MEV-proof transactions. All the financial privacy that Solana DeFi is missing — without mixers, without regulatory risk.
🧬
Encrypted NFT Metadata
Store NFT attributes as ciphertext. Reveal selectively with ZK proofs. Prove ownership of a trait without revealing which trait. Private collections, verified on-chain.
⚡
Sub-Millisecond Performance
38.5µs per operation. 2.17M ops/sec. No GPU required. The FHE runs on standard ARM/x86 CPUs. Your Solana program doesn't slow down — it gets encrypted.

Type anything. Watch it encrypt. Compute without decrypting.

✓ Your plaintext never existed on the blockchain. The computation happened on ciphertext. The result is cryptographically correct.
Demo 3 — MEV protection

Live from Solana Mainnet

Real Solana accounts. Real balances. Right now.

These are real accounts pulled live from Solana mainnet via Helius. This is what a validator sees today — and what they'd see with H33 Shield.
