How it works

  1. 01

    We watch known wallets

    Exchange hot wallets and large whale addresses on Ethereum — listed publicly for transparency.

  2. 02

    Big moves are filtered

    Transfers are priced in USD. Internal exchange shuffles between the same entity are hidden.

  3. 03

    Telegram, your minimum

    Pick the wallets you care about and your own minimum ($1M–$25M). You get a Telegram alert only for those. The dashboard still shows every move over $1M.

Read-only by design

We never hold, touch or ask for your funds or exchange keys. We only read public blockchain data.

Optional two-factor login (authenticator app) to protect your account.
