How to use the MetaMask Portfolio feature?

Understanding MetaMask Portfolio Overview

1. The MetaMask Portfolio feature provides users with a comprehensive view of their cryptocurrency holdings across multiple networks. By linking wallets and accounts, individuals gain real-time insights into asset distribution, transaction history, and portfolio value.

2. Access to the Portfolio is available through the MetaMask browser extension or mobile app by navigating to the 'Portfolio' tab. This centralized dashboard eliminates the need to switch between block explorers or third-party trackers.

3. Users can view balances in both native tokens (like ETH) and ERC-20 or other compatible tokens. The interface automatically aggregates data from connected chains such as Ethereum, Polygon, Arbitrum, and others supported by MetaMask.

4. Real-time pricing is pulled from decentralized market feeds, ensuring accurate valuation without reliance on centralized exchanges. Exchange rate fluctuations are reflected instantly within the portfolio summary.

Connecting Multiple Wallets and Accounts

1. To expand visibility, users can link additional Ethereum-compatible wallets to their MetaMask Portfolio. This includes hardware wallets like Ledger or Trezor when connected via USB or Bluetooth.

2. Importing external addresses is possible by adding public keys manually. Once added, these addresses appear under the 'Connected Accounts' section and display token balances accordingly.

3. Multi-chain support allows each imported wallet to show activity across various EVM-based networks. Switching between chains does not require re-importing accounts.

4. Permissions are strictly controlled—MetaMask never accesses private keys during this process. Data retrieval occurs through read-only blockchain queries using public node infrastructure.

Tracking Transactions and Performance Metrics

1. Each transaction associated with connected addresses appears chronologically in the Portfolio feed. Details include timestamp, network fee, sender/receiver addresses, and involved assets.

2. Token swaps executed via MetaMask Swap are labeled clearly, showing input and output amounts along with routing paths used by aggregators like 1inch or 0x.

3. NFTs held in linked wallets are displayed under a dedicated tab, showing previews, collection names, and current floor prices if listed on major marketplaces like OpenSea.

4. Historical performance charts illustrate net worth changes over time based on daily snapshots of total holdings. These visuals help identify trends tied to market movements or personal trading behavior.

Frequently Asked Questions

Can I track tokens on non-EVM blockchains using MetaMask Portfolio?Currently, MetaMask Portfolio only supports blockchains compatible with the Ethereum Virtual Machine. Networks like Bitcoin, Solana, or Cosmos cannot be directly monitored unless wrapped versions exist on an EVM chain.

Is there a cost to use the Portfolio feature?No fees are charged by MetaMask for accessing or using the Portfolio dashboard. However, on-chain transactions required to move assets will incur standard gas fees paid to miners or validators.

Does MetaMask store my transaction history centrally?Transaction data is fetched live from blockchain nodes rather than stored on MetaMask servers. Local device storage may cache recent records for faster loading, but no persistent cloud backup occurs without user initiation.

How often is portfolio value updated?Valuation updates occur dynamically as new blocks are confirmed on respective networks. Price feeds refresh approximately every 30 seconds, aligning with decentralized oracle update intervals.
