CoinShadowwallet alerts on Base

What is a free alternative to Arkham Intelligence?

Arkham’s distinguishing feature is attaching real-world identities to addresses. No free tool replaces that. If what you need is an alert when specific addresses move, a block explorer watch list or a Telegram bot covers it at no cost.

Arkham Intelligence describes itself, on its own site read on 4 September 2026, as deanonymizing the blockchain, and offers a multi-chain explorer alongside an intel marketplace. The identity layer is the point of the product.

As with any comparison, treat specifics as dated. I did not verify Arkham’s current plans or limits while writing this, so this page does not quote them; check their site if pricing matters to your decision.

Why de-anonymisation is hard to replace

Linking an address to a person or company means combining on-chain clustering with off-chain sources and keeping the result current as entities change wallets. It is continuous work rather than a one-off computation, which is why it is sold rather than given away, and why free equivalents do not appear.

If your question is genuinely "who owns this address", no free alerting tool answers it, and you should not expect one to.

What free tools do cover

The other direction: you already know the address, and you want to know when it moves. That needs no identity layer at all. A block explorer watch list will email you, and a Telegram bot will message you, both free.

This covers more real use than it sounds. Watching your own cold storage, a treasury whose address is published, a counterparty you were given the address for, or a wallet from a public leaderboard are all cases where identity is either already known or beside the point.

Getting some identity for free

Block explorers label large exchanges and many well-known contracts, which resolves a good share of the addresses you will actually encounter. Projects frequently publish their own treasury and multisig addresses in their documentation. Public dashboards name the big movers. None of it is comprehensive, and all of it is free.

What you cannot do for free is go from an arbitrary unlabelled address to a name. Be honest with yourself about how often you actually need that, as against how often it is simply interesting.

Do it in CoinShadow

Paste an address into the bot with Add wallet and you will be told when it moves, with a Basescan link on every alert so you can check the detail yourself.

Three addresses free, twenty-five on the paid plan with a dollar threshold on each. No account, no wallet connection, and no key at any point.

Questions

Is there a free Arkham alternative?

Not for identifying who owns an address. For alerting on addresses you already know, explorer watch lists and Telegram bots are free.

Can I find out who owns a wallet for free?

Sometimes. Explorers label major exchanges and contracts, and projects often publish their own addresses. Going from an arbitrary address to a name generally is not free.

Does CoinShadow label addresses?

No. You can give a wallet your own name so alerts are readable, but nothing is inferred about who owns it.

Which chains does CoinShadow cover?

Base only. Multi-chain explorers cover far more ground; this covers one chain and sends a message when something happens on it.
