The Arsenal
SEALED BY DESIGN
Every transaction remains invisible on-chain. Your strategy, your secret.
SHIELDED DEPOSITS
Deposit ETH or USDC and receive an encrypted note. Your balance is committed to a Merkle tree — invisible to on-chain observers.
PRIVATE BORROWING
Prove collateral adequacy without revealing how much you hold. Borrow against your hidden assets with a Groth16 ZK proof.
TIMELOCK PROTECTION
A 300-block timelock on borrows defends against flash-loan attacks. Health proofs auto-submitted by the keeper before every deadline.
VEIL STRENGTH SCORE
A real-time privacy score that grades your on-chain obscurity — factoring in note count, age, and health factor diversity.
AAVE V4 YIELD
Collateral is deployed into Aave v4's Hub+Spoke model. You silently earn yield while your positions remain sealed.
POSEIDON MERKLE TREE
A depth-20 Poseidon hash Merkle tree stores all note commitments. Inclusion proofs are generated client-side and never leave your browser.
The Ritual
HOW THE VEIL WORKS
Connect your wallet
Connect your Ethereum wallet on Sepolia. No account required — all state is stored locally and encrypted client-side.
Deposit & mint a note
Send ETH or USDC to the PrivacyPool contract. A cryptographic note is generated in your browser and stored encrypted in localStorage. Your balance is now invisible on-chain.
Borrow against your hidden collateral
Generate a Groth16 ZK proof of collateral adequacy without revealing amounts. Submit via the relayer — your borrow opens privately.
Maintain your health factor silently
The keeper service monitors your health factor and auto-submits health proofs on-chain before the 300-block deadline. If needed, repay or top up.
Withdraw to any address
Prove note ownership with a Merkle inclusion proof and spend your note. Withdraw to any address — severing any on-chain link to your original deposit.
The Lore
DECENTRALIZED.
PRIVATE.
NON-CUSTODIAL.
Occult Finance is a privacy middleware layer built on top of Aave v4. Users interact through shielded notes — cryptographic commitments that hide amounts and identity. All proofs are generated in your browser using Circom 2.0 circuits and verified on-chain by Groth16 verifiers.
No KYC. No registration. No compromise.
