How the ETH 50/50 Raffle Works
The 50/50 raffle is the simplest and most transparent fundraising model in existence. ETH5050 brings it fully on-chain with Ethereum smart contracts, eliminating every source of uncertainty and trust. Here's the complete mechanics:
Tickets Are Priced in ETH
Each ticket costs 0.0025 ETH. Every ticket purchase is a direct on-chain transaction. Your ticket is your immutable, verifiable entry into the draw.
Prize Pool = All Ticket Revenue
The prize pool grows with every ticket sold. 100% of ticket revenue enters the prize pool — there are no platform fees deducted from the pot.
Winner Gets Exactly 50%
When the raffle ends, a random winner is selected on-chain. They receive exactly 50% of the total ETH prize pool, automatically, in the same transaction.
Creator Gets Exactly 50%
The raffle creator simultaneously receives exactly 50% of the prize pool. Both payouts happen atomically — one cannot occur without the other.
