Wagyu

Self-custodial Monero and Zcash wallet with private swaps and a Hyperliquid bridge.

Wagyu is a self-custodial Monero and Zcash wallet for Chrome. Send, receive and store XMR and ZEC from your browser, swap supported assets without an account, bridge XMR to and from Hyperliquid, and pay on websites that accept Monero or Zcash. Your private keys are generated on your device, encrypted with your password, and never leave it. There is no account to create and no server that can spend your funds. WALLET FEATURES • Send and receive XMR. Every payment gets a fresh Monero subaddress, so incoming transfers cannot be trivially linked to each other. • Send and receive ZEC. Receive shielded Zcash on a unified address and rotate it when you choose, accept transparent deposits from exchanges, and shield them in one click with the fee shown first. • Know the real network fee before you commit. Wagyu builds and signs the transaction first, shows you exactly what it will cost, and only broadcasts once you confirm. An unusually high fee is flagged and needs your explicit acknowledgement. • Swap XMR or ZEC for other cryptocurrencies without creating an account. Before any funds leave your wallet, the order is checked against the quote you accepted and the payout address is shown to you. • Bridge XMR to and from Hyperliquid. • Manage several wallets: several accounts inside each Monero wallet, one account per Zcash wallet, each with its own card colour. • Track your transaction history: transfers, swaps and bridges in one list, filterable and exportable to CSV. • Light and dark themes. PAY ON WEBSITES, YOU APPROVE EVERYTHING Websites that accept Monero or Zcash can ask to connect to Wagyu, much like connecting a wallet to any web app. Nothing is shared until you approve it in a Wagyu window that shows the site's real address, as verified by the browser. Connecting gives that site one wallet address you pick. Every payment a site requests shows the recipient, the amount and the fee, and nothing is sent unless you confirm. Sites never see your balance, your other wallets or your wallet names. To make this possible, a small script runs on web pages; it does not read page content, forms or cookies. You can see and disconnect connected sites at any time in Settings. NON-CUSTODIAL BY DESIGN: HOW YOUR KEYS ARE PROTECTED Your recovery phrase (25 words for Monero, 24 for Zcash) is sealed with AES-GCM under a key derived from your password (PBKDF2-SHA256, 600,000 iterations) and stored only in this browser's extension storage. The password itself is never kept, and the derived key is non-extractable. The wallet locks itself after an idle timeout you choose, and shortly after you close the popup. Your scan progress is saved when it locks, so a long wallet restore picks up where it left off. Revealing your recovery phrase or private keys always asks for your password again, even when the wallet is already unlocked. Repeated wrong passwords are slowed down. When you create a wallet, Wagyu asks you to write the recovery phrase down and then type three of the words back before the wallet becomes usable. It is a small friction that prevents the one mistake you cannot undo. If you ever forget your password, the wallet can be removed from the device and restored from that phrase. REAL WALLETS, NOT WATCH-ONLY VIEWS Wagyu runs a full Monero wallet in WebAssembly and scans the blockchain itself. It is not a watch-only view of someone else's node. You can connect it to your own Monero node (monerod) in Settings, including a node running on your own machine. Zcash scans in your browser too, with a Rust/WebAssembly wallet engine. XMR and ZEC amounts are handled as exact integers from the field you type to the transaction that is signed; a value that cannot be represented is refused rather than rounded. Fiat and other-asset figures shown alongside are estimates. This release does not support Sapling-only or TEX Zcash recipients, spending legacy Orchard notes, automatic shielding, multiple Zcash accounts, or choosing a custom Zcash server. An incoming Zcash payment appears once its block is scanned, then stays pending until enough confirmations arrive. COMPATIBLE WITH FEATHER AND THE OFFICIAL MONERO WALLET Export your Monero wallet as a standard .keys file and open it in Feather Wallet, the official Monero wallet, or any wallet2-compatible client. Import one the same way. You are never locked in. PRIVACY: WHAT LEAVES YOUR DEVICE Like any Monero wallet, Wagyu syncs from a Monero node (node.wagyu.xyz by default, or one you choose in Settings), so that node sees your IP address and the transactions you broadcast. Zcash syncs from ChainSafe's public lightwalletd server (zcash-mainnet.chainsafe.dev). That server sees your IP address, the block range scanned, the transactions requested in full and the wallet's transparent address set, including unused and change addresses, even if you never use a transparent address. It is never sent your shielded addresses or keys and cannot read shielded amounts or memos. If you use swaps or the bridge, the amounts, the destination address you enter and an order identifier are sent to the Wagyu API so the order can be created and tracked; token logos are loaded from the same API. Opening Points sends your primary Monero address to the Wagyu API to look up your points. A website you connect receives only the address you approved and, for a payment you confirmed, its transaction id. Nothing else is transmitted: not your recovery phrase, not your private keys, not your password, and no analytics. Full privacy policy: https://docs.wagyu.xyz/privacy-policy SELF-CUSTODY, STATED PLAINLY Wagyu is self-custodial. If you lose both your recovery phrase and this browser profile, nobody, including us, can recover your funds. Write the phrase down and keep it offline. Requires Chrome 111 or newer.
