How Hopchain works

1. Paste an address

Drop any EVM wallet or contract address (or an .eth name) into the box on the home page and hit Check Wallet. Hopchain checks which chains that address has actually been active on — currently Ethereum, Polygon and Arbitrum, with more networks planned — and pulls its transaction history from every chain where it finds activity.

2. See who it's transacted with

Every address your wallet has directly sent to or received from becomes a node in the graph, sized by how many transactions connect the two of you. The All Connections list below the graph shows the same data as plain text — useful for scanning quickly or for connections too small to stand out visually.

3. Known entity vs. unknown address

Some addresses belong to things Hopchain can identify — exchanges, DeFi protocols, token contracts, bridges — and those show up amber, labeled by name. Everything else is an ordinary wallet or unlabeled contract Hopchain has no name for, shown in grey as "unknown." Unknown doesn't mean suspicious — most wallets simply aren't publicly labeled anywhere.

4. Click a wallet to explore its own network

Click any node — or any row in the connections list — and Hopchain "hops" to that address, showing its own connections in turn. This is how you trace a chain of wallets: where did this address's funds ultimately come from, or where did they end up? Each hop is a real, shareable URL, so you can send someone directly to a specific wallet's page.

5. Expand a connection to see exactly what moved

Click the small arrow (▸) next to any connection in the list to load the actual transactions between your wallet and that address — token amounts, which direction they moved, and when. Amounts sent from your wallet are shown in red, amounts received are shown in green.

6. What "Approval" means

An Approval isn't a transfer — it's a permission. When you interact with a DeFi app (a DEX, a lending protocol), you typically have to approve its contract to move a certain amount of a token on your behalf before it can actually do so. Hopchain shows these separately from real transfers, with the amount approved (or "Unlimited" if the app requested no cap — very common, but worth being aware of) and which contract received the approval. Read more about unlimited approvals and how to revoke them.

7. Flagged addresses get their own explainer

When a connection is flagged red as a known scam, exploit or phishing address, its badge links to a short guide page explaining why — what it's flagged as, and what to do about it.

8. It's free, and there's nothing to connect

Hopchain never asks you to connect a wallet or sign anything — it only reads public on-chain data for whatever address you type in. There's no account, no signup, and no limit on which addresses you can look up (reasonable rate limits just keep the tool available for everyone).
