      About the catalog

      How we build and grow the catalog

      Cryptofix is a living catalog, and we keep developing it: we look for new projects, add the ones that genuinely help, and update the lists regularly so they stay current.

      What “vetted” means

      We look at the official site, check that the project is live, and that the description matches what the service actually does. This is an editorial selection, not user reviews. We do not audit the code and we do not guarantee that a service is safe — before you send money to a third-party project, verify it yourself.

      How we score

      A score is our view of a service’s reliability, ease of use, usefulness and reputation. It is not a user rating and not a guarantee of quality — just a short guide to why one service sits above another.

      The catalog stays current

      Crypto moves fast: services appear, shut down or change their terms. We keep looking for new projects and update the catalog regularly — adding ones worth listing, removing what no longer works, and fixing descriptions.

      One payment · forever

      Unlock all 33 categories for 1 USDT

      One payment gives lifetime access. After the first unlock you get a recovery code. On a new device or after clearing your browser, enter the same TxID and that code. Access is always confirmed by our server, not by your browser.

      1. 1

        Send USDT

        Send 1 USDT on the Polygon network to this address:

        0x204321f650f30724CaAf3Caa2ffAF83Ac54338eF
        Network Polygon Token USDT Amount 1 USDT

        In your wallet, pick the official USDT on Polygon: it may appear as USDT or as USDT0, which is the same token. A different token with a similar name will not reach us.

        Contract on Polygonscan
        A different network or a different token will not work: the funds will not arrive, and we cannot refund them.
      2. 2

        Paste the TxID

        Paste the transaction hash (TxID):

      3. 3

        Check the payment

        We look up the transaction on Polygon and unlock every category on this page.

      • Payment is checked by our server: it reads the transaction on the public Polygon network — the address, the 1 USDT amount, and the confirmations. The browser alone never unlocks access.
      • We never ask for a seed phrase and we do not connect to your wallet. You send 1 USDT yourself, from your wallet, to the published address.
      • Questions about payment or access — write to Cryptofixbtr@yahoo.com, and we’ll reply.

      About the author

      I am an entrepreneur who studies crypto and builds projects with the help of AI. Cryptofix grew out of a simple idea: when you run into a crypto problem, you don’t want to dig through dozens of websites looking for a tool that actually works. So I collect the best ones in one place and update the catalog regularly.
