Kismetic runs tamper-proof prize draws on the blockchain. Upload your list, we handle everything else, and every participant can verify the result themselves.
/ kis·met /
noun
"Fate determined by forces beyond human intervention."
The foundation
Fairness you can prove, not just promise
Traditional raffles rely on trust in the organiser. Kismetic removes that requirement entirely.
Cryptographically secure
Every draw uses Chainlink VRF, on-chain verifiable randomness that no one, including Kismetic, can predict or manipulate.
Publicly auditable
Each result is permanently recorded on the Polygon blockchain. Any participant can independently verify the draw was fair.
Tamper-proof record
Participant lists are committed via Merkle tree before the draw runs. The record cannot be altered after the fact.
How it works
Simple for you.
Verifiable for them.
Upload your list
Import a CSV with participant names and emails. Set your draw date, either immediate or scheduled.
We run the draw
Kismetic commits your list to the blockchain and requests randomness from Chainlink VRF. No human involvement.
Share the proof
Winners are announced with a public verification link. Every participant can confirm the result independently.
Participant view
Every participant can verify their own result
After each draw, participants receive a personal verification link. They can confirm their entry existed, the randomness was genuine, and the winner selection was mathematically correct, without trusting anyone.
