What you need to hold

Reading today's price…

Check your wallet

Connect the Solana wallet that holds your $ZEROFEE. You sign one message to prove it's yours: no transaction, no approval, no fee.

How the check works

  1. Your wallet signs one short message. It costs nothing, moves nothing and approves nothing.
  2. We read the wallet's $ZEROFEE balance on Solana, with its last 30 minutes of history, and value it at the live price. Holding the amount above for at least 30 minutes unlocks the download.
  3. You get a download link that works for 10 minutes. Come back any time for a new one.

Coming soon

The ZeroFee Wallet source will be here for holders when it launches.

Coming soon

More source code for holders is on the way. It will be here when it's ready.

License, in short

The code is source-available under the PolyForm Noncommercial License 1.0.0.

  • You can run it, read it and change it for yourself, for personal, study, research and other non-commercial use.
  • You can't sell it, run it as a paid or commercial service, or use it to make money.

This is a summary. The LICENSE file in the download is the full text, and it is what applies.
