Primary Lottery Mechanics

Participation:

• Entry Requirements: Users must have 10 USDC to participate.

• Approval Process: Users need to approve the lottery contract to access their USDC.

• Lottery Entry: After approval, users click the "Enter with 10 USDC" button. This sends 10 USDC to the lottery contract, increasing the number of participants in the lottery.

Winner Selection:

• ChainLink VRF Integration: Once the final participant enters the lottery, the ChainLink VRF (Verifiable Random Function) is triggered to select the winner randomly.

• Settlement: The settleLottery() function is automatically called by an in-house bot. This function finalizes the lottery and transfers the winnings to the winner's wallet. - Manual Settlement: If the bot fails to execute the settlement, any user can manually settle the lottery by invoking the settleLottery() function through the smart contract interface on PolygonScan.

Rewards Distribution:

• Winners: The selected winner receives the total prize in USDC.

• Losers: Participants who do not win are minted loserUSDC tokens, which are non-transferable and can only be used for entry into the Second Chance Lottery.
