A screenshot of a random number isn’t proof
Certify every draw
Prove every winner
VeriDraw replaces free random number generators with cryptographic proof, an auditable certificate, and public verifiability.
Built for Commercial draw operators·Brand campaigns·Charities & fundraisers·PTAs & schools
Your entrants see the proof. Your regulators see the audit trail.
Run certified draws. Build trust.
Not just a random number generator
A complete draw management platform
Draw Dashboard
Create, schedule, and manage every draw from a single command centre. See what’s upcoming, what’s live, and what’s completed — with every certificate, result, and audit trail one click away.
Every Draw Type
Single-winner, multi-winner, instant wins, and combined competitions — all cryptographically certified. Every winner gets their own verifiable proof.
Live Draw Reveals
Run your draw live with animated reveal templates. Choose which prize to reveal next with the prize picker. Build excitement, stream it, make it an event.
Cryptographic Certificates
Every draw produces a permanent, public certificate at a unique URL. The winning number is locked with a commitment hash before tickets go on sale and combined with a Bitcoin block hash no one can predict. Entrants click “Verify” and their browser proves it’s fair — no trust required.
Certificate Analytics
Track certificate views, verification clicks, and verify rate. Turn proof-of-fairness into a marketing metric worth sharing.
Template Builder
Brand your live draw — accent colours, animations, ticker messages, and your logo. Save templates and reuse them across every draw.
Simple by design
Set up in minutes, certify in seconds
Create your draw & lock it in
Set up your draw on VeriDraw — name, prizes, close date. We generate a commitment hash that mathematically locks in the draw method before a single ticket is sold. Paste the hash on your draw page so entrants can see it from day one.
Run the draw on draw day
Enter tickets sold, click "Run draw." VeriDraw fetches the latest Bitcoin block hash from three independent block explorers — entropy no one could have predicted or influenced. The winning ticket is calculated instantly.
Share the certificate
A permanent, public certificate is issued at a unique URL. Share it with your entrants, post it on social media, embed it on your site. Anyone can click "Verify" and independently confirm the draw was fair — no trust required.
Locked before a single ticket is sold
Trust through transparency
VeriDraw’s cryptographic method means no one — not the operator, not VeriDraw, not anyone — can influence or predict the winning number.
Verification runs in your browser — no VeriDraw servers involved
Secret key published after draw — full independent audit possible
Permanent certificate URL — proof that never expires
There’s a difference between “verified for you”
and verifiable by you
Most “blockchain-verified” draws still generate the winning number on their own server, then simply record it on-chain. You have to trust their server was honest. VeriDraw is the only platform where the entropy, the method, and the result are all independently verifiable.
