Paste two or more addresses. Hopchain checks whether they share counterparties or a funding source — filtered so a common exchange or DEX (which almost any two active wallets would share) doesn't look like a meaningful link. Got a longer list? Check up to 50 at once and get clusters instead of one pairwise result.
Hopchain looks up the history of each address and compares two things: who first funded each wallet (where we can find it), and which counterparties the wallets have in common. Exchanges, DEX routers and large token contracts that almost every active wallet touches are filtered out, so they do not count as a link.
A shared funding source or a rare shared counterparty is a strong hint that two wallets belong to the same person or group. It is not proof: friends, a company paying several employees or a single exchange wallet can produce the same pattern. A result with no link only means that none was found in the history we can read.
Is the Sybil check free?
Yes. There is no signup and no wallet connection.
How many addresses can I compare?
Two to five at once. For a longer list use the bulk Sybil check,
which takes up to 50 addresses and groups them into clusters.
Does a shared link prove two wallets have the same owner?
No. It is evidence, not proof. See
how to tell if two crypto wallets are linked for what
counts and what does not.
