How DOLLA Works
From picking a lot to cashing out your winnings — everything is transparent, fast, and powered by blockchain technology.
4 Simple Steps
Getting started takes less than a minute. Here is how it works from start to finish.
Choose a Lot
Browse our marketplace of premium products. From the latest phones and laptops to luxury watches and gaming gear. Find what you want to win.
Buy DOLLA Tickets
Each DOLLA Ticket costs just 1.08 USDT/USDC. Buy one ticket or many to increase your chance of winning. Pay with crypto instantly.
Wait for Sellout
Once all tickets for a lot are sold, the draw happens automatically. Every ticket has an equal chance of winning. No manipulation possible.
Win & Cash Out
The winner receives DOLLA Tickets equal to the prize value directly to their balance. Withdraw anytime as USDT or USDC to your crypto wallet.
Why Crypto?
Traditional payment systems are slow, expensive, and restrictive. Cryptocurrency solves all of that. Here is why we built DOLLA on blockchain.
Lightning Speed
Transactions confirm in seconds on networks like Polygon, Arbitrum, and Base. No bank delays, no waiting days for clearance. Deposit and play instantly.
Unmatched Security
Blockchain transactions are immutable and cryptographically secured. No chargebacks, no fraud, no third-party interference with your funds.
Ultra-Low Fees
Network fees as low as $0.001 on L2 chains. Traditional payment processors charge 3-5% in fees. We pass those savings directly to you.
Global Access
Anyone with a crypto wallet can participate regardless of location. No bank account needed, no geographic restrictions, no currency conversion hassles.
True Ownership
Your funds are yours. No bank can freeze your account or block your transactions. You have full control of your assets at all times.
Full Transparency
Every transaction is recorded on a public blockchain. You can verify deposits, withdrawals, and prize distributions independently.
Supported Networks
Deposit and withdraw using any of these blockchain networks
100% Transparent & Fair
Every participant knows their exact chance of winning. Nothing is hidden. Everything is verifiable on the blockchain.
Exact Chance Per Ticket
Your chance = your tickets / total tickets. If a lot has 1000 tickets and you own 5, your chance is exactly 0.5%. Displayed openly on every lot page.
Equal Odds for Everyone
Every single ticket has the same weight. No hidden multipliers, no VIP advantages, no preferential treatment. 1 ticket = 1 equal chance.
Blockchain Verified
All ticket purchases, winner draws, and payouts are recorded on a public blockchain. Anyone can audit the entire history at any time.
Cancel & Refund Anytime
Changed your mind? Cancel your participation and get a full refund before the lot sells out. No questions asked, no fees, instant return.
Withdraw Anytime
Your DOLLA Tickets can be exchanged for USDT or USDC and withdrawn to your wallet at any moment. No lock-up periods, no restrictions.
Open Source Algorithm
Our winner selection formula is public. You can verify any past draw result yourself using freely available tools. We have nothing to hide.
Provably Fair
Our winner selection is mathematically verifiable. Nobody — not even us — can manipulate the outcome.
Server Seed Hash
Before the lot begins, we publish a SHA-256 hash of the server seed. This locks in our commitment.
Blockchain Hash
When the lot sells out, we use the block hash of the final transaction. This is unpredictable and public.
Winner Derived
The server seed + block hash are combined and hashed. The result modulo total tickets = winning ticket number.
winning_ticket = SHA256(server_seed + block_hash) % total_tickets
After the draw, the server seed is revealed so anyone can independently verify the calculation matches the pre-published hash.
Pre-Draw Verification
Hash is published before any tickets are sold. You can record it yourself.
Post-Draw Verification
Server seed is revealed. Compute SHA256 yourself to confirm the hash matches.
Block Hash is Public
The blockchain hash is visible to everyone on the public ledger. No one controls it.
Zero Manipulation
Neither DOLLA nor any participant can predict or influence the winning number.
