Track an Ethereum wallet by its address or ENS name

An Ethereum address rarely holds coins on Ethereum alone. The same address can have ETH on Base, USDC on Arbitrum and a governance token on Optimism, and every network's explorer shows only its own slice. Sonar reads one address across 26 EVM networks and shows each network as its own account in one portfolio, with no wallet connection and nothing to sign.

One address, 26 networks

Sonar checks your address on Ethereum, Base, Arbitrum, Optimism, Polygon, BNB Chain, Linea, Avalanche C-Chain, Ethereum Classic, ZKsync, Scroll, Mantle, Gnosis, Celo, Sonic, Cronos, Berachain, Blast, Unichain, World Chain, Ink, Soneium, Abstract, ApeChain, Monad and HyperEVM. Networks where the address holds nothing and has no history are left out, so your list stays short. The same address is also checked on VeChain and Hedera.

Paste an ENS name such as yourname.eth instead of the address if you like; Sonar resolves it to the address it points to.

All of it counts as one connected account, so the Free plan's single wallet can cover every EVM network your address uses.

What Sonar reads

• ETH and each network's native coin, such as POL on Polygon or BNB on BNB Chain.
• ERC-20 tokens, matched to assets by contract address, never by ticker. A copycat token with a familiar symbol isn't mistaken for the real one.
• Transfers in and out, so your history, cost basis and performance reflect what happened. On Mantle, Sonic and Cronos only balances are read.

Spam stays out

Ethereum addresses collect airdropped junk tokens. Sonar keeps only tokens that have a market price and a contract it recognizes, and skips positions worth less than $1. What you see is what you'd count.

What it doesn't value

NFTs aren't valued, and positions inside DeFi protocols, such as lending deposits or liquidity pools, aren't broken out. A receipt token Sonar can't match is left out rather than given a made-up price.

What you see

• Each network as its own account, so you can see what sits on Base versus mainnet, or filter to one network.
• Net worth with your stocks, exchanges and other wallets, and the change over any period.
• Holdings with price, 24-hour change, value, profit or loss and weight.
• Time-weighted performance next to Bitcoin and the S&P 500.

On Starter, every token you hold shows social data: mentions, engagement, sentiment, top creators and news. On Standard, coins also show onchain data such as holder counts, supply concentration and the largest recent transfers. Both cover only what you hold.

Wallets sync on their own: daily on Free, every 6 hours on Starter, Standard and Premium.

Safe by design

Sonar never asks for a seed phrase, a private key or a signature, and there's no "connect wallet" pop-up. It stores your public address, which anyone can already look up, and reads the chain. Nothing Sonar holds could move your funds. The guide to tracking a wallet by address covers what an address reveals and the scams to avoid.

More than one wallet

Add a hardware wallet, a MetaMask address and a Solana wallet side by side; each is one connected account. Free includes one, Starter three, Standard five and Premium ten. Wallets on other networks are on the crypto wallet tracker page, and exchanges such as Coinbase connect through Plaid on paid plans.

FAQ

Do I need to connect MetaMask?

No. Copy your address from MetaMask, Rabby, Ledger Live or any other wallet and paste it. Nothing is installed or signed.

Does it track Layer 2 networks?

Yes. Base, Arbitrum, Optimism, ZKsync, Scroll, Linea, Blast and the other networks listed above are read from the same address.

Can I track someone else's address?

Any public address can be read, but Sonar is built for your own holdings: it's added to your portfolio and counts toward your net worth.

Why is a token missing?

It may have no market price, a contract Sonar doesn't recognize, or a value under $1. Tokens that look like spam are skipped on purpose.
