//PRIVATE, GAS-FREE USDC VAULTS ON ETHEREUM

Your money, hushed. Deposit, earn yield, and withdraw without a trace.

USDC goes into Aave V3 and Morpho while it waits. A zero-knowledge proof made on your device lets you take it out, or borrow against it, with no link back to the wallet that put it in.

//HOW IT WORKS

In with one wallet. Out to another.

Every deposit becomes an anonymous leaf in a Merkle tree. To withdraw, you prove you own one of the leaves without saying which. A relayer submits it, so your wallet never shows up on the way out.

//YIELD SOURCES

Two of the deepest lending markets. Working for your note.

Every deposit is supplied to Aave V3 and a Morpho USDC vault on Ethereum. Your note tracks the blended growth of both, so a withdrawal pays out the deposit plus everything it earned.

//PRIVACY

One of many. Nobody knows which.

Every deposit in a vault is the same size. The chain sees that a note was withdrawn, never which one. Each deposit after yours makes the guess harder, and your yield keeps growing meanwhile.

PUBLIC

A deposit happened. Some note was withdrawn, to which address, for how much.

HIDDEN

Which deposit, who made it, and when, beyond a one-day window.

//WHY ETHEREUM

Settled on Ethereum. Nothing in between.

Hushfund runs directly on Ethereum mainnet, where USDC, Aave and Morpho are deepest. No bridge or extra chain sits between your deposit and your exit.

01 Deepest USDC liquidity Native USDC from Circle, and the largest Aave V3 and Morpho USDC markets. Yield is steady and withdrawals are not starved for liquidity.
02 Security of the base layer Deposits, proofs and payouts settle on Ethereum itself. No bridge, sequencer or sidechain stands between you and your funds.
03 Verified in the open Every proof is checked by an on-chain verifier contract, and every contract is published on Etherscan for anyone to read.
04 Gas-free on mainnet You sign, the Hushfund relayer submits and pays the Ethereum gas. Deposits, withdrawals, loans and repayments cost you no ETH.
05 Exit to any chain Ethereum is the hub. LI.FI bridges your withdrawal to Arbitrum, Optimism, Base and more, and ENS names resolve natively.
//SECURITY

Your exit can never be switched off.

01

Withdrawals cannot be paused

The owner can pause new deposits and loans in an emergency. Withdrawing and repaying always stay open.

02

Relayers cannot redirect funds

Recipient, relayer fee and loan amount are hashed into the proof. Change any of them and verification fails.

03

No front-running

Your USDC signature is bound to your own note, so nobody can reuse it for a deposit of theirs.

04

Always fully backed

Funds are split in the same ratio payouts use, and new notes start at the next yield bucket. The vault never owes more than it holds.

05

Time-locked strategy changes

Moving funds to another Aave or Morpho market needs two public days of notice, enough to leave first.

06

Multisig ownership, capped fees

Admin rights sit with a multisig and transfer in two steps. Protocol fees are capped at 1% in the contract.

//FAQ

Questions

What is a note?

A secret string your browser creates when you deposit. It is the only way to withdraw or borrow against that deposit. Hushfund never sees it and cannot recover it, so keep a copy somewhere safe.

How private is it?

The chain shows that a deposit happened and that some note was withdrawn, not which one. Privacy grows with the number of deposits after yours. Withdrawing straight away, or back to the wallet you deposited from, makes you easier to trace.

Where does the yield come from?

Your USDC is supplied to Aave V3 and a Morpho USDC vault on Ethereum. The rate floats with those markets.

What does it cost?

Gas is free: Hushfund pays the Ethereum gas for every deposit, withdrawal, loan and repayment. The only cost is a protocol fee of —% on withdrawals, shown before you confirm.

What happens when I borrow?

You receive up to 70% of your note’s value. The debt grows at the vault’s yield rate, the same as your collateral, so there are no liquidations. Repay any time to unlock the deposit and get a fresh note.
