Answers to the most common questions about ZEC-backed loans and Zcash DeFi.
Yes. You can wrap ZEC as WZEC (ERC-20) and use it as collateral on Ethereum-based lending protocols like Aave or MakerDAO if the protocol supports WZEC. You can also use centralized lending platforms that accept ZEC directly.
Typical loan-to-value ratios for ZEC collateral range from 50% to 70%. At 50% LTV, $1,000 of ZEC collateral lets you borrow $500 in stablecoins. Higher volatility assets tend to get lower LTV ratios to provide a liquidation buffer.
If ZEC price falls and your collateral value drops below the liquidation threshold (typically 80–85% LTV), your position may be partially or fully liquidated. You can avoid this by adding more collateral or repaying part of the loan before reaching the threshold.
You can use cross-chain bridges like RenBridge to wrap ZEC into WZEC (ERC-20) on Ethereum. The process involves sending ZEC to the bridge contract and receiving WZEC in your Ethereum wallet. Note that bridging requires using a transparent Zcash t-address.
As of 2025, Zcash does not have native smart contract programmability. DeFi with ZEC currently requires bridging to Ethereum. Zcash Shielded Assets (ZSAs) are in development and could enable future native private DeFi on the Zcash protocol.
WZEC is Wrapped Zcash - an ERC-20 token on Ethereum that represents ZEC locked in a bridge contract. 1 WZEC = 1 ZEC at peg. WZEC lets ZEC holders participate in Ethereum DeFi while maintaining ZEC exposure.
Yes, partially. Bridging ZEC to Ethereum requires a transparent t-address transaction, which is public. All Ethereum DeFi activity is also fully public. To minimize privacy exposure, shield the ZEC you're not bridging, and re-shield after unwinding DeFi positions.
Impermanent loss occurs when you provide liquidity to a ZEC/ETH or ZEC/USDC pool and the price ratio changes. If ZEC rises 2x, you lose approximately 5.7% compared to just holding the tokens. Trading fees can partially or fully offset this loss.
Decentralized lending protocols are non-custodial in that funds are held in smart contracts, not by a company. However, smart contract risk still exists - bugs can result in loss of funds. Centralized lending services are custodial and carry counterparty risk.
Common ZEC yield strategies include: providing WZEC/ETH liquidity on Uniswap for trading fees, lending WZEC on Aave for interest, using WZEC as collateral to borrow stablecoins for further yield farming, and mining ZEC directly. Each has different risk profiles.
