Our decentralized bankroll has temporarily shut down on 31th August 2020. We have payed out all PINK holders and we are working on version 2.0 and hope to restart this project soon.


Create the backend of a gambling application within an hour with our powerful API. (See Documentation)
Provide users a 100% provably fair gambling experience with WAX blockchain technology
Never worry about having too little money to start a gambling site because the dapp will manage the risk and sends you payments each time a user wagers.
Invest in the bankroll and earn WAX passively, even if you're not a developer

Example Application

The first site built on top of our bankroll service

betpink.gg implements all of the awesome things that our bankroll service offers. The main game mode is a 40 second cycle roll with 4 different outcomes to bet on. The bets of all players are shown, as well as a history of the past results. A secondary game mode "Dice" offers players instant bets with customaizable odds / multipliers. The bets of all players are shown, as well as a history of the past results. There also is a chat for everyone to use, which runs completely over the pink.network API. The entire site is 100% front-end only, which would be unthinkable without the powerful API that pink.network offers.

How does it work?

Instead of having to fund an own bankroll, developers are able to directly use the bankroll of our smart contract. Both the odds of winning as well as the payout of a bet are completely customizable, and even linking multiple bets of various users to a single outcome is possible. The 3rd party developer is paid completely indifferent from the outcome of the bets. For example, lets assume a bet of 100 WAX with a 50% chance of winning and a 1.9x payout was created.

Statistical House edge = 1 - 0.5 * 1.9 = 1 - 0.95 = 5%
Bankroll fee = 1%
3rd party edge = 5% - 1% = 4%
3rd party payout = 100 WAX * 4% = 4 WAX

Regardless of whether the user wins the bet or not, the developer utilizing our bankroll will always be paid exactly 4 WAX. This shifts the risk completely away from the developer, and allows for a stable income without any risks.

The core of our system is a smart contract, allowing anyone to place bets on outcomes of their choosing. The randomness for these bets is provided by the WAX Random Number Generator, which can guarantee unpredictable randomness to all parties involved. The contract will also allow anyone interested to contribute to the bankroll by staking their own WAX tokens. This will allow the contract to accept higher bets, benefiting the ecosystem directly. Because of the guaranteed house edge of 1% in every bet, this will allow for a relatively low risk investment over medium to long timespans.

Gambling Site

betpink.gg became the first gambling site implementing our bankroll service. It provides a useful example for 3rd party developers (available here).

What is pink?

Just like the bankroll itself, the PINK token runs as a smart contract on the WAX blockchain and follows the eosio.token standard. They are not meant to be traded speculatively, but rather are to be seen as shares in the bankroll. If you own 20% of all PINK tokens, you can exchange those for 20% of the WAX in the bankroll. That means that the PINK price is directly linked to the development of the bankroll, and to nothing else.

1 PINK = 0 WAX

From a technical perspective this means that when somebody deposits WAX into the bankroll, new PINK tokens are issued proportionally. The only exception is for the first ever deposit, where the exchange rate was set to 1 WAX : 10 PINK.

Issued PINK = (Deposited WAX) / (WAX in bankroll) * (PINK supply)

When you want to exchange your PINK back to the proportional share of the bankroll, those PINK tokens are burned, and the WAX from the bankroll are paid out.

WAX paid out = (PINK burned) / (PINK supply) * (WAX in bankroll)

What this means is that the PINK/WAX exchange rate will only ever change when the bankroll wins or loses WAX. Deposits to or withdrawals from the bankroll have no effect on the exchange rate. In other words, the price at which you invest into PINK shouldn't influence your decision at all. If you deposit 1,000 WAX today and the bankroll makes a 10% profit, then your PINK tokens will now be worth 1,100 WAX, no matter at which exchange rate you invested.

New PINK tokens are only ever issued when the corresponding amount of WAX is deposited in the bankroll. They are never just created out of thin air, not by us and not by anyone else.


You can invest your WAX tokens into the bankroll and profit from the guaranteed house edge that every bet has. This also helps grow the ecosystem as a whole, by enabling players to place higher max bets. Interested in learning more?

Become an investor


In order to simplify the process for 3rd party developers, we have built a HTTP + Websocket API that almost entirely abstract the interaction with the blockchain. Dealing with any blockchain directly can be quite tricky. By giving developers access to a simple to use API, we significantly lower the burden of entry and make it possible to run gambling services without any backend whatsoever. On top of that, we also have released a NPM module, which makes our service very easy to use for javascript developers
