metamask close account: You can't "close" an on-chain address. You can remove the wallet from a device or uninstall the app, but the blockchain address (and private keys) still exist. If you want the device forgets the wallet, delete the extension/app and remove any exported private keys.
metamask delete wallet: Uninstalling the extension or app removes local data. To fully restore later you must keep your seed phrase. If you have no seed phrase, funds may be irrecoverable.
metamask deleted my wallet: Often the wallet looks "deleted" because of a missing seed phrase, wrong browser profile, or you switched to an empty account (different derived address). Check your address on a block explorer first.
metamask close connection: Use the Connected Sites view to disconnect a dApp. But disconnecting does not revoke token approvals — those must be checked separately.
metamask demo account: There isn't a one-click demo mode. Use a testnet (Goerli/Sepolia), faucet ETH, or run a local node (see local development) to simulate trades without real funds.
(Short answers above. Keep reading for step-by-step fixes and reproductions.)
Removing MetaMask from a device does not move funds. Funds remain on-chain tied to the private keys. See remove-uninstall for a deeper guide.
Common pitfall: the tokens are present but hidden because you’re on the wrong network. Check network selection and use add-custom-tokens-to-metamask.
But disconnecting doesn't remove existing token allowances. To revoke approvals, follow the steps at token-approvals-and-revoke.
Want to experiment without real ETH? Two options:
If you run a local node or Ganache, connect with a custom RPC. See local-development-ganache-geth.
A short checklist like this solves most common problems fast.

What I did (so you can repeat):
Results: seed phrase restores all derived accounts. Imported accounts require their private keys. Revoke tests: disconnecting a dApp removed site access but did not remove previously granted allowances (so I used the approvals tool to revoke). If you want to replicate: follow the steps in each section above.
| Feature | Extension (desktop) | Mobile app | Hardware (via MetaMask) |
|---|---|---|---|
| dApp browser / in-app browsing | Partial (injected provider) | Yes (in-app browser + WalletConnect) | No (transactions must be signed on device) |
| WalletConnect support | Yes | Yes | Yes |
| Built-in swap aggregator | Yes | Yes | Limited (signing via device) |
| Manage Connected Sites | Yes | Yes | Limited |
| Hardware wallet integration | Can connect | Can connect | Native (recommended for cold storage) |
Q: Is it safe to keep crypto in a hot wallet? A: Hot wallets are convenient for daily DeFi and small balances. For large holdings use a hardware wallet. Follow daily-security-practices and never expose your seed phrase.
Q: How do I revoke token approvals? A: Disconnect the dApp (Connected Sites) and use an approvals manager (see token-approvals-and-revoke). Revoking costs gas.
Q: What happens if I lose my phone? A: If you have your seed phrase you can restore on another device. If not, funds are likely lost. See lost-phone-reset-recovery.
If your immediate problem is a missing wallet, start by confirming on-chain balances and locating your seed phrase. But don't panic if things look wrong — most issues are recoverable with the right backup. For step-by-step walkthroughs, try the setup and recovery pages: create-metamask-wallet, recover-lost-wallets, and remove-uninstall.
Want hands-on guidance? Follow the step-by-step repair paths above and run the same quick tests I used (backup → uninstall → restore). If you'd like a specific checklist for your device or scenario, ask and I’ll walk you through it.
(And one last practical tip: keep a tiny amount of ETH in a secondary burner account for gas testing before moving larger balances.)
