Shield has introduced the first confidential onchain trading pair for Zcash (ZEC), enabling users to trade and provide liquidity without making their wallet activity public. The new market is built on Shield's concentrated-liquidity automated market maker (AMM) running on the Aleo blockchain, and it is now accessible through Shield's non-custodial wallet.
This launch expands Shield's supported markets by adding ZEC to its platform. Users can now manage ZEC alongside other assets in the wallet, and a one-click banner prompt moves funds into a shielded balance, making them ready for trading. The wallet maintains encrypted records, and users retain full control of their private keys and funds.
How Zcash Protects Transaction Data
Zcash, which launched in October 2016, supports both transparent and shielded transactions. Transparent addresses operate similarly to Bitcoin addresses, with balances and transaction histories visible to anyone. Shielded transactions, however, encrypt the sender, recipient, and amount while still allowing the network to verify that each transaction complies with its rules. Zcash was the first widespread implementation of zkSNARKs, demonstrating that a decentralized network can validate transactions without revealing underlying financial details.
ZEC on Shield
On Shield, ZEC trades against USDCx in a concentrated-liquidity pool. Traders can move between ZEC and a dollar-pegged asset, while liquidity providers can allocate capital within their chosen price ranges. Shield Swap operates on Aleo, combining publicly verifiable market state with encrypted wallet records. Zero-knowledge proofs allow the network to verify transactions without exposing confidential wallet data.
Traders can inspect prices and available liquidity before confirming a swap, and liquidity providers can evaluate the pool before deciding where to allocate capital. Pool reserves, prices, trade sizes, and fees remain publicly verifiable, but wallet balances, portfolio composition, and links between trades stay confidential.
Protecting ZEC Portfolios
Trading on a transparent chain creates a permanent history tied to wallet addresses. Once an address is linked to a trader, its balances and transaction history become visible to anyone following the market. While fresh addresses can complicate analysis, trade sizes, timing, and repeated behavior can still reveal connections. Over time, these patterns can expose how a trader builds positions, rebalances, or moves capital between assets.
Shield Swap addresses this exposure by ensuring that public market data does not provide a direct view into each participant's wallet and broader portfolio. For ZEC holders, this means access to onchain trading without making their wallet history part of the market information available to competitors.
Providing Liquidity for ZEC/USDCx
The ZEC/USDCx pool allows traders to switch between ZEC and a dollar-denominated asset. Liquidity providers choose the price ranges where their capital is active and earn fees when their liquidity is used. A narrower range concentrates capital around selected prices, while a wider range makes liquidity available across more prices. Providers can adjust their positions as market conditions and their objectives change.
ZEC in Your Shield Wallet
Shield's non-custodial wallet now supports ZEC, allowing users to manage the asset alongside other supported holdings. Users can connect their wallet to Shield to trade or provide liquidity. Shield currently covers Aleo network fees for swaps, and the liquidity-provider fee is included in the quote before the user approves the trade.
ZEC/USDCx trading is now available on Shield, with early access open to eligible organizations and individual market participants. Interested parties can visit swap.shield.fi to access the market or shield.fi/docs for documentation.
