Provably Fair
Every draw is mathematically verifiable. We cannot cheat — and you can prove it.
Why is DOLLA fair?
Before any tickets are sold, the system locks a secret number (server seed) and publishes its encrypted fingerprint (hash) on the Polygon blockchain. Nobody — including us — can change this number after it's locked. When all tickets sell out, the winner is calculated using this locked number combined with the exact moments each ticket was purchased. You can verify everything yourself below.
How it works (4 steps)
Seed locked
A random secret is created and its hash is recorded on Polygon blockchain — before anyone buys.
You buy tickets
Every purchase time is recorded. These timestamps create a second number that nobody can predict.
Winner calculated
Locked secret + purchase timestamps = winner ticket number. Pure math, no human decision.
You verify
After the draw, we reveal the secret. You can check that it matches the blockchain hash and recalculate the winner yourself.
