DON’T TRUST. CHECK.

Fairness, in your hands.

Recalculate a draw right here in your browser. Nothing is uploaded. Change even one winning ticket and the check will catch it.

Bring the evidence.

Every result has a reason.

Load a proof and run the check.
You’ll see what matches, and what doesn’t.

This is a calculation verifier: it checks the math inside the proof file. It does not independently authenticate the external entropy source, prove publication timing, or confirm real transfers.

Take our website out of the equation.

Download standalone verifier

The open-source verifier is a single file with no extra packages. Download a proof from any result page and run it independently with Node.js 22 or later.
