Today we are proud to publish the results of our 3rd party security audit

In the wake of The DAO and in following best practices for smart contract security, Etheroll contracted Piper Merriam for 3rd party independent security audits of the entire suite of our smart contracts. We are very proud to have had the opportunity to work with Piper for the purposes of securing our smart contracts. Piper Merriam is well known for his work on maintaining a lot of the Python tooling for Ethereum, working with Vitalik Buterin on PoC implementations of Casper, and of course the Ethereum Alarm Clock (among other things). Piper was a speaker at Devcon 1 and more recently, a speaker at Devcon 2. Piper is highly regarded within the Ethereum community, specifically in regards to smart-contract security, and we are most certainly very proud to announce that we have recently satisfied the requirements of his smart contract security audits. You can view the results of the crowdfund security audit below.

After reviewing the updated source all issues have been satisfactorily addressed.

You can also find the PGP signed version here. This is a major step forward for Etheroll and emphasizes how serious we are about building secure smart-contracts and implementing best practice development methodologies, meaning you can feel confident playing a part in the future of Ethereum dice gaming with Etheroll.

Many thanks to Piper Merriam for his work in ensuring the security of our smart contracts.

Our crowdfund opens February 13. To learn more and pre-register your interest visit, play our beta game or read our whitepaper. You can talk with us at r/etheroll and follow us @etheroll.

We are very proud today to announce our public beta and upcoming crowdfund

We have a completely new dice game that is in beta and available to play on Ropsten testnet. You can find it at Because we are currently in beta mode our smart contract is currently deployed only to the Ropsten network, so no real Ether is currently at stake.

Our new UI brings the full experience of traditional dice games to Ethereum.

Players can set their own odds using our slider which means they can set their own % chance of winning (adjustable odds) as low as 1%, or as high as 98%. This means players can adjust each bet they place to suit their own individual risk profile. Our house edge is a low 1% and there are no sign-ups or deposits required.

Our random number is sourced via via This is currently the safest way for us to generate random numbers. We will continue to develop our random number generation, and this is certainly not the final implementation, it will require a continually iterative approach.

To play, we currently recommend using the Mist browser. You can use Metamask (which we love) to place bets, but please note there is an issue that we have raised with Metamask here and as always, they are working on a fix, so we will update you as soon as that happens.

Ropsten testnet block times are slow, sometimes taking up to 1 minute for each block. Our bets are processed in ~3 blocks. We are restricted by block times, however, as Ethereum moves towards PoS block times will come down to < 3 seconds, which means our bet processing times will be much faster.

Announcing the Etheroll crowdfund

We now have a security audited dice game ready to roll on Ethereum, now all we need is a house bankroll in order to accept and payout winning bets. That is why we are inviting you to bet on the house.

Fuel the crowdfund with Ether during our token creation phase, and you become the holder of ÐICE (ROL) tokens which grants you rights to a share in the profits the house generates, as well as the right to vote on proposals (new games/features/house edge).

During the crowdfund, when our crowdfund address receives Ether, ÐICE (ROL) tokens are sent directly to the sender.

Each ÐICE token grants its owner the following rights and has the following characteristics:

Direct earnings – Proportional to the number of tokens they hold. Token holders as a collective receive 100% of the profits generated by the house every 12 weeks.

Tradeable – The ÐICE token will be tradeable on popular exchanges.

Voting rights – Token enable holders to vote on proposals. For example, lowering or raising the house edge, or, adding a new game to the suite.

Important Details

Start Date: The ÐICE (ROL) token creation phase begins at 10:00 UTC February 13th 2017
Duration: 14 days.
Conversion schedule:
Week 1: 1 Ether (Ξ) for 200 ÐICE (ROL) tokens
Week 2: 1 Ether (Ξ) for 100 ÐICE (ROL) tokens
# of tokens available: 25,000,000

Note: The founding team is pre-allocated 10%. Any tokens that may remain unsold after the token creation phase will be destroyed to rule out any possibility of dilution. There will never be another mintage of ÐICE tokens.

Use of funds
80% of Ether created during the crowdfund will go directly to the bankroll which forms the house bank in order to pay winning bets and generate Ether via the 1% house edge.

20% of Ether created during the crowdfund will go directly to Etheroll for continued development of the ecosystem.

Token holders as a collective receive 100% of all Ether the house generates. Rewards are available to token holders on a recurring 12 week cycle. The amount of rewards available to each token holder is proportional to the amount of tokens they hold in relation to the total supply. For example, if you own 10% of all tokens, you would be allocated 10% of all the rewards available, in perpetuity.
