We have built a fast and reliable way to double your ETH, our powerful verified randomization comes from the Oraclize API - and we provide better odds than a roulette wheel at a 49.21% win rate. We are also doing a non-traditional ICO where any losing bet will earn FLIP Tokens just by playing EtherFlip (They will automatically be sent as they are built into the contract). For more information on FLIP Tokens (or to simply say hi), check out our Subreddit. We plan to distribute earnings to FLIP Token holders in the future.

There is also a small chance to earn MDT (Million Dollar Tokens) everytime you play. We plan on running interesting concepts with MDT, with the first being able to spend MDT to capture all earnings of the EtherFlip contract for a given period of time (i.e. for a 6 hour time block).

Randomization has always been an incredibly difficult feat to accomplish on the blockchain. The random byte we use is created by a verifiable proof housed on a Ledger Nano S via the Oraclize team. To learn more, we encourage you to read up about this API and how it works here. Each transaction will consume gas in order to ensure the round trip verification of the random byte. This gas will come out of the initial amount of ETH sent to the contract. As we scale, we will increase the amount that can be sent from 0.1 to 10+ ETH, perform enhancements on gas pricing, and build fun and interesting features into our product.

Why use EtherFlip? Our odds are among the best in the industry, and we are using a method that is not exposed to a 4th party (such as We are also doing a unique ICO by giving away FLIP Tokens and MDT just for playing EtherFlip.

In the instance that you win, the smart contract will automatically send back the (amount*2) - (transCost*2) to the same address the initial ETH came from.

**When using EtherFlip, do not use exchange based wallets or you will not be able to earn FLIP or MDT.
