    Not just that it moved. Where it surfaced.

    A transfer is half the story. Spout follows the funds hop by hop until they come up: at an exchange deposit, a bridge or a fresh wallet. The alert carries the whole trail.

      Public chains and public tags. Nothing else.

      Spout reads what a block explorer shows to anyone. It needs no exchange account, no login and nobody’s keys.

      How a wallet gets its label

      Sample wallet
      Public tag
      johndoe.eth is a name the owner published on the chain. Spout shows it as written.
      Heuristic
      Early holder comes from behaviour: funded years ago, quiet since. It is a guess, and it is marked as one.
      Never
      Who a private person is. Spout labels wallets, not people: no legal names, no faces, no home addresses.

      Before you download Spout

      What does it read?
      Public blockchains such as Bitcoin, Ethereum and Tron, and wallet tags that are already public. The same data any block explorer shows.
      Can it see private things?
      No. It cannot see inside an exchange, a private chain or anyone’s account. A label such as “Early holder” is a public tag or a guess from on-chain behaviour, not the identity of a private person.
      Where do my watch lists and alerts go?
      They stay on your PC. Spout fetches public chain data and shows the alert on your desktop. There is no account to create.
      Is this allowed?
      Reading a public blockchain is what anyone can do by hand. Follow each data source’s terms and your local law, and do not use Spout to harass anyone. It is not investment advice: it says what moved, never what to buy or sell.

      Be there when it surfaces.

      For investigators, journalists, security and due-diligence teams.
