WalletConnect lets mobile software wallets interact with desktop and mobile dApps without a browser extension. That matters because most users spend their day on phones. I use MetaMask Mobile for daily swaps, staking and dApp auth. But the UX differences between using the in-app browser and WalletConnect can be subtle. This guide explains the flows, shows how to fix the common "deep link not supported metamask" error, and gives concrete steps you can copy.
WalletConnect creates a secure session between a dApp and a mobile wallet using a URI or QR code. The session authorizes the dApp to request transactions, signatures, and chain changes. With MetaMask Mobile the flow becomes:
Why is this better than a browser extension? You can sign transactions from a phone while browsing on desktop. But there are trade-offs. WalletConnect sessions persist until you explicitly disconnect. And long sessions are a potential attack surface if you forget to revoke them.
Below are the practical steps I follow. Try them yourself.
(And yes — sometimes opening the dApp inside MetaMask Mobile's built-in browser avoids WalletConnect entirely because the wallet becomes the injected provider.)
That error is common when the dApp tries to call a URI scheme that the OS or app won't open. Here are reproducible fixes I used.
How to fix deep link not supported metamask — short checklist:
If none of this works, try the dApp's support channel or test the connection with a different wallet to confirm the problem is a link, not the dApp.
Step-by-step:
Why do this? WalletConnect sessions can remain active for weeks. If you granted approvals to a dApp, disconnecting the session does not automatically revoke token allowances.
Want to know if a MetaMask Snap is active (developer or power-user question)? Here are reliable checks I use:
Note: Snap support on mobile has historically been limited compared with the extension. If you rely on a Snap, verify compatibility before depending on it for signing or special transactions.
| Method | Best for | Pros | Cons |
|---|---|---|---|
| In-app browser (MetaMask Mobile) | Mobile-first dApps, quick swaps | Injected provider, fewer steps, single-app flow | Limited to what the in-app browser supports |
| WalletConnect (v2) | Desktop-to-mobile workflows | Cross-wallet, QR/URI, multi-chain sessions | Sessions persist; deep-link issues can occur |
| Browser extension (desktop) | Heavy DeFi users, hardware wallets | Full dApp UX, hardware integrations | Not available on phone (requires extension) |
What I ran and how you can reproduce it:
To repeat: pick a reputable dApp (try a read-only sandbox first), trigger Connect → WalletConnect on desktop, scan the QR with MetaMask Mobile, then approve a test signature. Watch the mobile prompts and then disconnect via Settings → Connected Sites.
Q: Is it safe to keep crypto in a hot wallet? A: Hot wallets are convenient for daily DeFi. But convenience trades off with risk. I treat hot wallets like my daily cash: useful for frequent activity, not for long-term storage of large amounts. Hardware for cold storage is better for large balances.
Q: How do I revoke token approvals? A: Use the token approvals UI in MetaMask or visit the dedicated revocation page. See token-approvals-and-revoke for step-by-step instructions.
Q: What happens if I lose my phone? A: You need your seed phrase to recover on a new device. If you used cloud backups for the seed phrase, consider the trade-offs. See backup-and-recovery-seed-phrase.
Q: how to disconnect metamask mobile from website? A: See the earlier section or follow disconnect-and-remove-connected-sites.
Q: how to determine if metamask snap is connected? A: Check the Snaps page in MetaMask (extension), the dApp's permission UI, or the developer-level RPC call if you're building a dApp.
WalletConnect plus MetaMask Mobile gives you real flexibility: sign desktop transactions on your phone, use mobile-only features, and avoid installing an extension. But sessions persist, and deep link issues happen. My practical tip? Use QR or the in-app browser when possible, and routinely clean up Connected Sites and token approvals.

If you want a tailored troubleshooting checklist for your specific device and dApp, I can walk through it with you — tell me your OS and whether you saw a QR code or a mobile link.
