MetaMask — Token Management & Portfolio Tracking
Overview
This page explains how to manage tokens inside MetaMask, and how to use its built-in portfolio features. The focus is practical: how to add custom tokens, hide the spam, fix common display problems, and keep your token approvals tidy. I use MetaMask daily across desktop and mobile, so these notes come from hands-on testing and a few mistakes I learned from (yes, I once approved a contract I should not have). What I have found is that small habits—checking a contract address or limiting allowances—save a lot of hassle.
If you are new, start with the extension or mobile install guides: install-metamask-extension and install-metamask-mobile-app.
Where tokens live: extension vs mobile
Short answer: both the extension and the mobile app show tokens, but the experience differs.
Mobile: Includes a Portfolio view that aggregates balances and shows basic charts. The mobile dApp browser makes adding tokens on the go easier. If you mostly use a phone, this is where you will check balances most often.

How to add a custom token (step by step)
This covers common searches like add custom token metamask and add token metamask. Follow these steps before pasting any contract address.
- Confirm the chain. Switch MetaMask to the network where the token lives (Ethereum, BSC, Avalanche, Polygon, etc.). If the network is missing, add it first via the relevant guide, e.g. add-bsc-network, add-avalanche, add-polygon.
- Find the token contract on the chain's block explorer (for example, Etherscan for Ethereum). Verify the address, decimals, and symbol.
- In MetaMask extension: Assets > Import tokens > Custom Token. Paste contract address. Symbol and decimals should auto-populate. Click Add Token, then Import Tokens.
- In MetaMask mobile: Wallet > Tokens > Add token or + > Import token. Paste contract address, confirm details, add.
And yes: you can add most ERC-20 style tokens the same way on any EVM-compatible network.
Add BEP20, AVAX, Polygon tokens quickly
Want to add a BEP-20 token on BSC? Switch to BSC first, then follow the same import steps. For AVAX tokens use the Avalanche network and the same import flow (search for add avax token metamask if you need a checklist). For Polygon, switch to Polygon and then add the token (search add polygon token metamask). If a token is legitimate but not auto-detected, the contract method always works.
Token not showing? Troubleshooting checklist
Search queries like token not showing metamask are common. Try this checklist in order:
- Am I on the correct network? Wrong chain is the most common cause.
- Is the address correct? Copy it from the project website or block explorer. Beware impersonator tokens with similar names.
- Does the block explorer show the balance for your address? If not, the token balance is zero on-chain.
- Did you add the token to the correct account? Check multiple accounts in MetaMask.
- Try Reset Account (Settings > Advanced > Reset Account). This clears local transaction history but not balances. Use with care.
- If the network uses a custom RPC, the node may be behind. Switch RPC or re-add the chain.
If none of that helps, check out advanced connectivity guides like add-custom-network and mobile-desktop-sync.
Hide spam tokens and tune token detection
Spam tokens are annoying. MetaMask lets you hide individual tokens, and adjust automatic token detection.
- To hide a token: open the token detail and choose Hide or Remove (wording can vary between extension and mobile). Hiding only affects your local view; the token still exists on-chain.
- To stop automatic discovery: Settings > Security & Privacy > Token detection. Turning off detection prevents unknown tokens from appearing automatically, which helps if you see many dust tokens.
But remember: hiding tokens only removes visual clutter. It does not revoke approvals or stop contracts from interacting with your address.
Portfolio tracking: what to expect and common issues
MetaMask mobile provides a portfolio view that sums balances and shows recent performance. The extension offers asset balances per account and price indicators for recognized tokens.
Common portfolio issues (metamask portfolio issue):
- Missing USD value: price feeds are aggregated; new or illiquid tokens may not have a price listed.
- Incorrect totals: if you have tokens on multiple networks that are not added to MetaMask, those balances will not show.
If accuracy matters, cross-check with a block explorer or a dedicated portfolio tracker. For deeper tracking, see token-management and tokens-portfolio.
Token approvals and security: practical steps
Token allowance is one of those features that gives DeFi power and also risk. Approving a contract allows it to spend tokens on your behalf. Unlimited allowances are convenient for frequent swaps but increase exposure.
Practical steps I follow:
- Only approve specific amounts when possible. If a dApp asks for unlimited allowance, consider setting a custom, smaller approval.
- After a risky interaction, revoke token approvals. You can use the in-wallet connected sites list to disconnect dApps, and external tools to revoke approvals. See token-approvals-revoke.
- Regularly check connected sites. A long-unused dApp should be disconnected.
I once left an unlimited approval for a small token and regretted it. Lesson learned: review approvals after trades.
NFTs and token visibility
NFTs are treated separately from fungible tokens. MetaMask can display NFTs on supported networks; if a questionable collection appears, hide it using the NFT or collection settings. For more on handling collectibles see nft-management.
Who this setup is best for (and who should look elsewhere)
Who this works for:
- Active DeFi users who want a flexible software wallet for swaps, staking, and dApp interactions.
- People who use multiple EVM-compatible chains and need to add custom tokens.
Who should consider other options:
- Large-balance holders who need stronger protection. A hardware wallet or multisig is better for high-value custody. See hardware-wallets-overview.
- Users who want automatic, multi-chain portfolio aggregation across non-EVM chains (solana limitations apply; see solana-limitations).
FAQ
Q: Is it safe to keep crypto in a hot wallet?
A: Hot wallets are convenient for daily DeFi activity. They are inherently less secure than cold storage. Use small operational balances for swaps and a hardware wallet for long-term holdings.
Q: How do I revoke token approvals?
A: Disconnect the dApp in MetaMask and use a revoke tool or the blockchain explorer to revoke allowances. Walkthrough: token-approvals-revoke.
Q: What happens if I lose my phone?
A: If you have your seed phrase, restore your wallet on another device using create-restore-wallet. Without the seed phrase or private keys, you cannot recover the funds. Read more on backup options: backup-cloud-vs-paper.
Conclusion and next steps
Managing tokens and your in-wallet portfolio is mostly about attention to detail: confirm contract addresses, stay on the correct network, and keep approvals tight. If you want a step-by-step setup walkthrough for desktop or mobile, check these guides: install-metamask-extension, install-metamask-mobile-app, and create-restore-wallet. And if you handle larger sums, consider combining MetaMask with a hardware wallet; see connect-ledger for integration notes.
If you ran into a specific metamask portfolio tracking problem, try the troubleshooting checklist above and follow the network-specific guides like add-bsc-network or add-polygon.
