How to use the "Portfolio" view on MetaMask? (Asset Tracking)

Understanding the Portfolio View Interface

1. The Portfolio view in MetaMask displays all supported assets held across connected networks, including Ethereum, Polygon, Arbitrum, and others.

2. Assets are grouped by network and sorted by current market value in USD, with top holdings appearing first.

3. Each asset card shows token name, symbol, balance, price per unit, 24-hour change percentage, and total value.

4. A search bar at the top allows filtering tokens by name or symbol, useful when managing dozens of tokens.

5. Network toggle buttons let users switch between EVM-compatible chains without leaving the Portfolio screen.

Adding and Managing Custom Tokens

1. Users can manually add ERC-20, ERC-721, or ERC-1155 tokens by clicking “Add Token” and selecting “Custom Token”.

2. Entering a valid contract address triggers automatic detection of token standard, decimals, and symbol if the contract is verified on Etherscan or equivalent explorers.

3. Unverified tokens appear with a warning icon and require manual confirmation before display.

4. To remove a token, users long-press (on mobile) or hover and click the trash icon (on desktop), then confirm deletion from the Portfolio list.

5. Hidden tokens remain in wallet storage but do not appear in the Portfolio view unless explicitly unhidden via settings.

Tracking Real-Time Price Data

1. MetaMask pulls price feeds from CoinGecko for over 10,000 tokens, updating every 30 seconds during active sessions.

2. Price changes reflect live market conditions but may lag slightly during high volatility or low liquidity events.

3. Users can tap or click the “i” icon next to any token to see historical chart, market cap, and trading volume sourced directly from CoinGecko’s API.

4. Fiat denomination defaults to USD but supports EUR, GBP, JPY, and CAD through the Settings > Preferences > Currency menu.

5. Staking rewards, yield positions, and LP tokens are not auto-included unless integrated via third-party dApps that register balances using MetaMask’s Snap framework.

Exporting Portfolio Data

1. Desktop users can export a CSV file containing token name, symbol, balance, network, and USD value via the three-dot menu in the top-right corner.

2. Exported files include timestamps and UTC timezone metadata, aiding audit trail compliance for tax reporting tools.

3. Mobile exports require sharing to external apps like Google Sheets or Excel, with no native CSV generation on iOS or Android.

4. Historical portfolio snapshots are not stored locally; only the current state is exportable at any given moment.

5. Third-party portfolio aggregators such as Zapper or DeBank must be granted explicit read-only access to fetch balances — MetaMask does not share private keys or transaction history during this process.

Frequently Asked Questions

Q: Does the Portfolio view show NFTs from non-Ethereum chains?Yes, provided the chain is supported and the NFT collection has been indexed by MetaMask’s NFT detection service. Solana and Bitcoin Ordinals are excluded unless added via custom RPC and compatible NFT APIs.

Q: Why does my token balance appear as zero even though it shows on Etherscan?This occurs when the token contract uses a non-standard balanceOf implementation or when the wallet has not yet synced the latest block from that network. Switching networks or refreshing the page usually resolves it.

Q: Can I track wrapped tokens like wBTC or stETH alongside their native counterparts?Yes, both appear separately in the Portfolio list. MetaMask treats them as distinct assets based on contract addresses, even if they represent the same underlying value.

Q: Is portfolio data encrypted when synced across devices?All balance and asset metadata synced via MetaMask Sync is end-to-end encrypted using the user’s Secret Recovery Phrase as the encryption key. No plaintext asset data is stored on MetaMask servers.
