How ETH5050 V3 Works
ETH5050 V3 is a Web3 50/50 raffle system built on Ethereum Layer 2 networks. RandProofRNG powers verifiable winner randomness, and RandProofAutomation helps trigger finalization when raffles end or sell out.

FAQ
Frequently Asked Questions
Does ETH5050 V3 use RandProofRNG?
Yes. ETH5050 V3 uses RandProofRNG direct funding for verifiable winner randomness on Base, Optimism, and Arbitrum.
What does RandProofAutomation do?
RandProofAutomation can trigger raffle finalization when a raffle reaches its end time or sells out, helping the draw move from ticket sales to winner selection without manual operation.
What is the 0.0001 ETH reserve for?
The V3 creation payment includes a 0.0001 ETH decentralized finalization reserve that helps fund RandProofRNG, RandProofAutomation, and fallback settlement.
Can the contract owner manipulate results?
No. Winner selection uses RandProofRNG randomness fulfilled on-chain. No admin can choose the winner or replace the random result.
Can I verify the winner myself?
Yes. The raffle contract events, RandProofRNG request, fulfillment, finalization, and payout history are visible on-chain.
What if someone controls multiple wallets?
Each ticket has an equal chance regardless of who owns it. Multiple wallets do not affect randomness; they only mean that person owns more tickets.
Why did my ticket purchase fail or revert?
Most failed buys come from MetaMask Smart Account mode (EIP-7702): the wallet wraps the purchase in a delegation batch that roughly doubles gas usage, so larger buys can exceed the gas estimate and revert. Open MetaMask → account settings → turn off Smart Account for that account (or use a regular account), keep a little extra ETH for gas, and retry.
