MetaMask Zcash Snap Integration Guide

For a full walkthrough and visual explanation, watch this YouTube guide :

MetaMask now supports shielded Zcash (ZEC) via the ChainSafe-developed Zcash Snap, allowing you to send, receive, and manage private ZEC directly in your browser wallet. Audited by Hacken and listed in the official MetaMask Snaps Directory, it requires no separate Zcash software - only MetaMask and the Snap.

Prerequisites

MetaMask Extension (desktop only) - Chrome, Edge, or Firefox. MetaMask Account - Seed phrase secured; Snap derives Zcash keys from it.
Stable Internet Connection - For syncing with the Zcash network.
Funds - ETH to swap for ZEC or ZEC from an exchange.

Tip: Protect your MetaMask recovery phrase - it controls both ETH and ZEC.

Additional Notes

Use the latest MetaMask version - public release supports Snaps.
Shielded proofs may take time, WebAssembly handles computation in-browser.
Recovery is simple,install MetaMask and the Snap, then import your existing seed.
The Snap defaults to shielded ZEC, transparent addresses are not the focus.
Use zcashblockexplorer.com for transaction confirmations.
