Transparency Dashboard
Every number is verifiable on-chain. Here's how the protocol works under the hood.
Open-Source Smart Contract
The 1DollarMillion V2.1.1 contract is fully open-source and verified on Etherscan. Anyone can read the source code, audit the logic, and verify that the prize distribution (995,350 / 3,650 / 1,000 split) is hardcoded and cannot be changed. The contract inherits OpenZeppelin's ReentrancyGuard, SafeERC20, and Ownable — the gold standard for secure DeFi code. The owner can only pause the contract in emergencies and claim accumulated fees; they cannot access user deposits or alter the draw mechanism.
The Solvency Invariant
The protocol maintains a strict solvency invariant: total assets (raw USDT + aUSDT) must always be greater than or equal to total principal (user balances + pool + locked amounts + fees). This is enforced by the contract's accounting logic and a post-draw fix-up block that reclassifies phantom yield as principal if needed. You can verify this at any time by calling the accountingSummary() function — if the solvencyGap is green, the protocol is healthy.
How Aave Yield Funds Bonus Draws
When you deposit USDT, the contract keeps a 5% liquidity buffer in raw USDT (for instant withdrawals) and supplies the rest to Aave V3. Aave mints interest-bearing aUSDT to the contract, which accrues yield 24/7. The contract tracks 'principal supplied' separately from 'yield earned' (yield = aUSDT balance − principal supplied). When yield alone reaches $1,000,000, a bonus draw fires automatically — same Chainlink VRF selection, same $995,350 prize. Your principal is never at risk; only the interest is paid out.
