How to use Zapper with MetaMask? (Portfolio tracking)

Connecting MetaMask to Zapper

1. Open the Zapper website in a desktop browser compatible with MetaMask, such as Chrome or Brave.

2. Click the “Connect Wallet” button located in the top-right corner of the homepage.
3. Select MetaMask from the list of available wallet options.
4. Confirm the connection request in your MetaMask extension popup.
5. Ensure you are on the correct network—Zapper supports Ethereum, Polygon, Arbitrum, Optimism, and others—but defaults to Ethereum mainnet unless manually switched.

Viewing Your Portfolio Overview

1. Once connected, Zapper automatically scans your wallet address across supported chains for tokens, LP positions, staked assets, and protocol integrations.

2. The dashboard displays total portfolio value, asset allocation breakdown, and 24-hour change percentage.
3. Each token appears with its name, symbol, balance, current USD value, and percentage of total holdings.
4. Hover over any token to see its contract address, chain origin, and underlying protocol if applicable.
5. Assets held across multiple chains are grouped by network, with toggle switches allowing quick filtering.

Tracking Yield Positions and Liquidity Pools

1. Navigate to the “Yield” tab to view all active staking, liquidity provision, and farming positions.

2. Zapper identifies protocols like Aave, Compound, Uniswap V3, Curve, Balancer, and SushiSwap without manual input.
3. For each position, it shows deposited assets, pool composition, APR estimates, and claimable rewards.
4. Clicking into a specific position reveals historical performance, impermanent loss metrics, and withdrawal instructions.
5. Some positions include one-click “Harvest” or “Claim” buttons that trigger MetaMask transaction confirmations.

Managing Multiple Wallets and Networks

1. Use the wallet selector in the top navigation bar to add or switch between different MetaMask accounts.

2. Toggle between chains using the network dropdown next to the wallet icon—each selection reloads portfolio data for that chain.
3. Zapper caches balances per address per chain, so switching networks does not reset tracked data.
4. Imported wallets retain historical transaction parsing, including bridged assets and cross-chain swaps.
5. Disconnecting a wallet removes its balance display but preserves cached metadata until manually cleared.

Frequently Asked Questions

Q: Does Zapper store my private keys?A: No. Zapper never accesses or stores private keys. It only reads public blockchain data and relies on MetaMask to sign transactions locally.

Q: Why are some of my tokens missing from the portfolio summary?A: Tokens may be absent if they reside on an unsupported chain, lack verified contract metadata, or are held in non-standard ERC-20 contracts without proper decimals or symbol implementation.

Q: Can I track NFTs with Zapper?A: Yes. Zapper displays eligible NFTs held in your connected wallet under the “NFTs” section, including collection name, token ID, floor price, and marketplace links where available.

Q: Is Zapper safe to use with MetaMask?A: Zapper is a non-custodial interface. It requires read-only access to your wallet address. Never approve any transaction that requests unlimited token allowances unless explicitly intended for a known DeFi interaction.
