The Problem It Solves

🎯 Core Problem: Traditional Lotteries Are Risky & Unfair

Traditional lotteries require users to give up their money with only a small chance of winning. If you don't win, your money is gone forever. This creates a fundamental problem:

• High Risk: You lose 100% of your deposit if you don't win
• No Transparency: You can't verify if the draw was fair
• Centralized Control: Operators control the funds and results

✨ AveLot's Solution: No-Loss Lottery

AveLot revolutionizes lotteries by making them completely risk-free:

1. Your Principal is Always Safe 🔒

• Deposit USDC to enter the lottery
• Your deposit is automatically returned after the round ends
• Only the interest earned becomes the prize pool
• You can't lose your original deposit - withdraw anytime after round ends

2. Powered by Aave Protocol 💰

• Your deposits are sent to Aave, a battle-tested DeFi lending protocol
• Aave generates yield on your USDC (currently ~3-5% APY)
• The accumulated interest becomes the prize pool
• Winner takes all the interest, everyone else gets their deposit back

3. Completely Transparent & Fair 🎲

• All lottery logic runs on smart contracts (Base blockchain)
• Winner selection is verifiable on-chain
• No central authority can manipulate results
• Anyone can audit the code and verify fairness

4. Instant Withdrawals ⚡

• Exit anytime after the round ends
• Get your full deposit back immediately
• No waiting periods or approval processes
• Your funds, your control

Challenges I Ran Into

🔥 Major Technical Challenges

1. Smart Contract Integration with Viem v2

The Problem:

• Viem v2 has breaking changes from v1, and most tutorials use v1
• Type safety issues with contract function calls
• Confusing error messages like "Contract function reverted"

The Hurdle:

// This would fail silently or give cryptic errors
const result = await publicClient.readContract({
  address: CONTRACT_ADDRESS,
  abi: ABI,
  functionName: 'currentId'
});

The Solution:

Created a custom 
useViemWithPrivy
 hook that properly initializes Viem clients
Implemented proper type casting for BigInt values
Added comprehensive error handling with user-friendly messages
Used Viem's built-in formatUnits and parseUnits for USDC (6 decimals)
2. USDC Token Approval Flow
The Problem:

Users need to approve USDC spending BEFORE entering the lottery
Two-step transaction process is confusing for users
Need to check allowance and only approve if necessary
Managing loading states across multiple transactions
The Hurdle:

User clicks "Enter Lottery" 
→ Transaction fails because USDC not approved
→ User confused, doesn't know what went wrong
The Solution:

Built automatic approval detection and handling
Created seamless UX with clear status messages
