Monero vs Zcash: privacy models, wallets, and how to swap between them

Two answers to the same question

Bitcoin's ledger is public, so anyone can follow coins from address to address. Monero and Zcash both fix that, but they made opposite design decisions.

Monero makes every transaction private and gives users no way to opt out. Ring signatures hide which output is being spent among 16 candidates, stealth addresses give every payment a one-time destination, and RingCT hides the amount. The result is one uniform anonymity set: every Monero transaction looks like every other.

Zcash offers privacy as a mode. Transparent addresses (t-addresses) work exactly like Bitcoin; shielded addresses use zero-knowledge proofs (zk-SNARKs, today in the Orchard pool) to hide sender, receiver and amount completely. Historically most Zcash activity was transparent; since wallets such as Zashi began shielding by default in 2024–2025, the shielded share has grown, but the two pools still coexist.

What "private by default" changes in practice

With Monero you do not have to think about pools. Whatever you receive is private, whatever you send is private, and the only thing that can leak is metadata outside the chain — your IP address if you use a remote node, or the transparent chain on the other side of a swap.

With Zcash you have to manage two states. Coins at a t-address are as public as Bitcoin. Shielding them costs one transaction; spending from the shielded pool then reveals nothing. When you receive ZEC from a swap it arrives at a transparent or unified address, and you decide whether to shield it. If privacy is the reason you hold ZEC, shielding immediately after receipt is the habit to build.

Receiving each coin from a swap

• XMR: paste your wallet's primary address or, better, a fresh subaddress. No payment ID. Payout appears after one Monero block, spendable after about 10.
• ZEC: paste a unified address (u1…) from a modern wallet or a t-address. Legacy shielded-only z-addresses are not accepted by swap services, including this one. Payout is visible after one 75-second block.

Wallets

• Monero: Monero GUI/CLI, Feather (desktop), Cake Wallet, Monerujo (mobile). Running your own node is the strongest setup; remote nodes see your IP.
• Zcash: Zashi (mobile, shielded by default), Ywallet, Zingo, Zcash full node. Hardware wallets support transparent ZEC; shielded support is limited.

Fees and speed when swapping

Both coins have negligible network fees; the cost of a swap is dominated by the exchange spread and the fee of the other side of the pair. Timing is set by confirmations: 5 Monero confirmations take about 10 minutes, 6 Zcash confirmations about 8 minutes. The pair pages show the current all-in cost live for a sample amount.

Moving between the two, and to the rest of the market

There is no direct XMR ↔ ZEC pair on SyntheticSwap at the moment; the practical routes go through a major asset or a stablecoin:

• XMR → BTC → ZEC: XMR → BTC, then BTC → ZEC.
• ZEC → USDT (ERC-20) → XMR: ZEC → USDT, then USDT (ERC-20) → XMR.

Each hop is a separate swap with its own deposit and payout; the intermediate asset is transparent, so use a fresh address for it.

Into and out of the market:

• BTC → XMR, ETH → XMR, USDT TRC-20 → XMR and back.
• BTC → ZEC, ZEC → USDT ERC-20.

Which one?

• You want privacy without managing it, and you accept that some exchanges will not touch the coin: Monero.
• You want a coin that regulated venues still list, a fixed supply, and are willing to shield actively: Zcash.
• Many people hold both: XMR for private spending, ZEC as a shielded store of value with broader on-ramps.
