Presenting you the new cryptocurrency raffle project -
With Dextera it's possible to earn money by selling goods, and also it is possible to win something very valuable for a fraction of a price. is based on the Blockchain technology and particularly on Ethereum smart-contracts.

Anyone can create a new raffle and earn by selling tickets.

The raffle algorithm is very simple, absolutely honest and completely transparent.

For an example:
Mac Book Air is on sale with the following conditions:
number of tickets: 150,
ticket price: 0.017 ETH,
sale period: 55 days.

The real price of a laptop in stores is approximately $1200
The sale price is: 150 tickets x 0.017 = 2.55 ETH, which at the current exchange rate (February 1, 2018) equals to $2,850

A profitable transaction for both the seller and the buyer.
The buyer risks $20 with a chance of 1/150 to win a cool laptop.
And the seller sells his goods at about a double price.

How does it work?
- When creating a raffle a new Ethereum smart-contract is generated with the specified parameters, which can not be changed later.
- Tickets are purchased by sending a price of 0.017 ETH to the address of a smart-contract (one person can buy as many tickets as he or she wants).
- The winner is determined randomly after the last ticket is sold.
- The seller passes the prize to the winner, and the winner confirms the receipt of the prize by sending 0 ETH to the smart-contract.
- The smart-contract sends the collected funds to the seller, minus 10% commission of the
- If the winner does not confirm receipt of the prize within 30 days, the smart-contract makes a refund to all ticket buyers.
- If not all the tickets are sold within the specified period (55 days in our example) the smart-contract will return the funds to all ticket buyers.

Absolutely fair raffle, which is ensured by the transparency of the Ethereum smart-contract.
Everyone can see their chances of winning and know the risks.

The only thing is required from the seller is to attract the attention to the sale.

You can sell anything you like: a phone, a laptop, a concert ticket, a travel certificate, a certificate to a beauty salon, a subscription to a sports club, collectables and so on.

You can also earn the Ethereum cryptocurrency through a referral program to attract buyers to any product.
We are ready to pay up to 50% from the sale of each ticket to your Ethereum wallet.
