How to see my portfolio's total value across different networks in MetaMask?

Understanding Portfolio Aggregation in MetaMask

1. MetaMask does not natively aggregate portfolio values across multiple networks within its standard interface. The wallet displays balances separately per network — Ethereum, Polygon, Arbitrum, BSC, and others — without summing them into a single USD-equivalent total.

2. Users must manually switch between networks using the network selector located at the top-right corner of the interface to view token balances on each chain individually.

3. Native asset balances like ETH, MATIC, or BNB appear directly under the “Assets” tab when the corresponding network is active, but wrapped tokens or bridged assets may not auto-appear unless added manually.

4. Token detection relies on contract address recognition; if a token exists on multiple chains with different addresses, MetaMask treats them as distinct assets unless explicitly imported on each network.

5. Historical transaction data remains isolated per network — no cross-chain balance history or cumulative profit/loss calculation is available inside the base wallet.

Using Built-in Portfolio Tracking Features

1. Enabling the “Portfolio” toggle in Settings > Advanced activates a simplified value summary visible on the main Assets screen, showing approximate USD values for supported tokens on the currently selected network.

2. This feature pulls price data from CoinGecko and applies it to on-chain balances, but only for tokens listed in MetaMask’s default token list or those manually added with correct decimals and contract address.

3. Multi-chain portfolio totals do not appear even when Portfolio mode is enabled — users still need to navigate each network and mentally sum displayed values.

4. The Portfolio view excludes non-standard tokens, governance tokens with low liquidity, and tokens deployed on testnets or unsupported EVM-compatible chains.

5. Currency display preferences (USD, EUR, BTC) affect only the unit shown — they do not alter how balances are fetched or aggregated across networks.

Leveraging Third-Party Portfolio Trackers

1. Platforms like Zapper, DeBank, and CoinGecko Portfolio allow users to connect their MetaMask wallet via WalletConnect or API key to pull real-time balances across dozens of EVM-compatible chains.

2. These services scan known contract addresses on each network and reconcile duplicate tokens — such as USDC on Ethereum and USDC.e on Avalanche — using standardized identifiers like Coingecko IDs.

3. Cross-chain NFT holdings also appear in consolidated views, though some trackers exclude certain marketplaces or layer-2-specific collections unless manually synced.

4. Portfolio trackers often support historical net worth charts, asset allocation breakdowns, and yield farming position tracking — features absent in MetaMask’s native UI.

5. Security considerations include granting read-only access; however, private keys remain untouched as connections rely on signature-based wallet authorization rather than seed phrase exposure.

Manual Calculation Methods

1. Exporting wallet addresses and querying blockchain explorers like Etherscan, Polygonscan, or BscScan provides raw token balances, which can then be converted using live price APIs or spreadsheet formulas.

2. Browser extensions like Chainlist or DefiLlama Token Lists help identify correct contract addresses for tokens duplicated across chains, reducing misidentification errors during manual entry.

3. Spreadsheets with dynamic price feeds (via Google Sheets IMPORTXML or custom scripts) enable semi-automated aggregation when paired with exported balance data from each network’s explorer.

4. Some developers maintain open-source CLI tools that accept a list of wallet addresses and target networks, returning JSON-formatted totals with USD conversion based on decentralized oracle inputs.

5. Manual reconciliation becomes increasingly error-prone beyond five networks due to inconsistent decimal handling, token name collisions, and missing metadata for newly deployed tokens.

Frequently Asked Questions

Q: Does MetaMask support importing wallets from non-Ethereum-compatible chains like Solana or Cosmos?A: No. MetaMask only supports EVM-compatible networks. Solana, Cosmos, and other non-EVM blockchains require dedicated wallets like Phantom or Keplr.

Q: Why does my USDT balance show zero on Arbitrum even though I bridged it from Ethereum?A: You likely hold USDT on Ethereum but have not bridged it to Arbitrum or added the correct Arbitrum USDT contract address to your MetaMask token list.

Q: Can I see staking rewards earned across multiple networks in one place inside MetaMask?A: No. Staking positions and accrued rewards are not tracked by MetaMask. External dashboards like Lido Dashboard or Rocket Pool Explorer are required.

Q: Is there a way to auto-refresh portfolio values without switching networks manually?A: Not natively. Third-party trackers offer automatic refreshes across all connected networks, while MetaMask requires manual network selection to update displayed values.
