There exists a smart contract on xDai, a side-chain of Ethereum, that allows speculators to buy and sell emojis. These 💩coins fluctuate in value based on the hashes of mined blocks. Participants can earn a profit buying low and selling high.

This experiment is at an intersection of usability and onboarding with simple games that reflect the nature of our ecosystem. It’s really more of a bounty than an economically sound product. The goal of the player is to drain the bank of xDai which can be exchanged for real cash.

Participants will receive a paper wallet containing a private key:

After scanning this private key with their camera phone, users will have a wallet that is preloaded with $5 of 🤑emojicoin. This coin can be used to buy and sell emojis as they fluctuate in price.

If you have followed along with our Cypherpunk Speakeasy events, you know that the Burner wallet was built to run on top of an ERC20 token deployed to xDai. This helps us control the custom logic of the token and how it can be withdrawn:

Each account also has an allowance to offramp up to $100 in 🤑emojicoin from the bank to xDai. They can choose to immediately offramp their $5 to fiat or continue playing the game by investing in 💩coins:

The bank holds all the xDai that can be exploited, keep an eye on the prize:

To win, players must buy and sell coins as prices fluctuate. With a single tap of a finger they interact with the smart contract without even knowing it.

Participants can use the “Exchange” button to move between currencies and trade their 🤑emojicoin for real value:

Exchange ETH<->DAI with uniswap.exchange or DAI<->xDai with the POA bridge.

You can see in the contract that the prices of the 💩coins are based purely on the average of random hashes coming from mined blocks. This system is meant to be gamed and that is part of the fun.
