β½ Gas Fees for External Wallets
If using an external wallet like MetaMask or Coinbase Wallet, you'll need a small amount of POL (Polygon's native token) to pay for gas fees. Transactions typically cost less than $0.01. InApp wallets (social login, email, phone) have free gas fees sponsored by JackpotChain.
It depends on your wallet type:
π Traditional Wallets (MetaMask, Coinbase, Trust Wallet)
You'll need to complete a two-step process:
Approve DAI Spending
First click approves the JackpotChain contract to spend the required amount of DAI from your wallet. This is a standard security feature for all ERC20 tokens.
Purchase Tickets
After approval is confirmed, the purchase button becomes available. Click it to complete your ticket purchase.
π± Social Login & Smart Wallets
β¨ One-click purchase! Both transactions (approval and purchase) are batched together automatically. No need for two separate confirmations.
βΉοΈ Why is approval needed? This security mechanism prevents unauthorized contracts from accessing your tokens. You explicitly grant permission for specific amounts.
DAI is a stablecoin issued by MakerDAO, a decentralized autonomous organization on the blockchain.
Key Features:
- Value Stability: DAI is pegged to the US Dollar (1 DAI β $1 USD)
- Decentralized: Not controlled by any single company or government
- Blockchain-Based: Transparent and verifiable on-chain
- Widely Accepted: Used across DeFi platforms and applications
Why we use DAI:
DAI's price stability ensures predictable ticket pricing - 1 ticket always costs 1 DAI (β$1), making budgeting easy and transparent.
There are several convenient ways to purchase DAI:
π³ Buy Directly on JackpotChain (Recommended)
The easiest way to get DAI for tickets:
- Click your DAI balance in the top menu anytime
- Or use the "Add DAI to Wallet" button when you have insufficient funds
- Pay with credit/debit card or Apple Pay
- DAI arrives directly in your wallet
Our integrated payment solution supports multiple convenient payment methods:
Note: Apple Pay and Google Pay availability depends on your region and the payment provider (Coinbase, Stripe, or Transak).
βΉοΈ Limit Increases: Your weekly purchase limit can increase from $1,500 to $10,000 over time as you build transaction history and complete verification.
Minimal KYC is required for your first purchase to comply with regulations and ensure user safety.
β One-Time Verification
After completing KYC for your first purchase, no further verification is needed for future purchases on the same platform.
π‘ Special Case: Coinbase
If using Coinbase as your payment provider: No KYC required for purchases below $500 with a debit card.

The winner is chosen using Chainlink VRF (Verifiable Random Function), which provides a provably fair and tamper-proof source of randomness directly on the blockchain.
π² Why VRF?
- Cryptographically secure randomness
- Verifiable on-chain
- Impossible to manipulate or predict
- Trusted by leading blockchain projects
This ensures that the selection process is completely transparent and fair for all participants.
Absolutely! β
Since JackpotChain operates on a public blockchain, all transactions are recorded on-chain and fully transparent.
What you can verify:
- All ticket purchases
- Total jackpot amount
- Winner selection process
- Chainlink VRF randomness proofs
- Prize distribution transactions
You can independently verify the fairness of each draw by reviewing the smart contract interactions and cryptographic proofs on the blockchain.
π No One Controls It
The jackpot funds are held within an autonomous smart contract on the blockchain. No single entity or individual has control over the funds.
Think of it this way:
The smart contract is like a perfectly neutral robot that:
- Only executes the rules written in its code
- Holds the funds securely until the draw occurs
- Automatically transfers the prize to the winner
- Cannot be controlled or manipulated by anyone
This ensures complete transparency and security for all participants. There is no company or person who could misuse the money.
β Absolutely Not!
The rules of the lottery and the handling of funds are governed by the immutable smart contract code, which cannot be changed once deployed on the blockchain.
What this means:
- No one can alter the lottery rules
- No one can access or steal the funds
- No one can manipulate the draw results
- No one can prevent prize distribution
You can view all transactions on the blockchain explorer for complete transparency.
π What you can track:
- All ticket purchases
- Jackpot distributions to winners
- Smart contract interactions
- Complete lottery history
- Prize amounts and recipients
View on Polygonscan:
JackpotChain ContractThis transparency allows you to independently verify all activities and ensure the lottery operates fairly.
Your chances of winning depend on the total number of tickets sold for that particular draw.
How it works:
Since each ticket has an equal chance of winning, the more tickets you buy, the higher your probability of winning.
Scenario:
- Total tickets sold: 100
- Your tickets: 10
- Your winning chance: 10%
Formula: (Your Tickets Γ· Total Tickets) Γ 100
The only way to improve your odds is by purchasing more tickets. Each additional ticket increases your chances proportionally.
