Guess WAVES/USD Rate Dapp

Published on 04/09/2019 staff recently completed a first simple Dapp, Guess The WAVES/USD Rate. In this DAPP you need guess WAVES rate against USD at a certain future blockchain height.

You can bet by specifying in this page how much WAVES/USD rate will be on a certain blockchain height. Each bet costs 5 WLT plus 0.005 WAVES , you can bet at most on 5 rates for each address. If you confirm with WAVES KEEPER your bet will be recorded in a Smart Contract.

Betting on a rate

You will be able to bet on the rate upto 2880 blocks before the final height. For example, if the contest is to guess the WAVES/USD rate at height 1002880 you will be able to bet upto height 1000000. If another player did already bet on a certain WAVES/USD rate, you won't be able to bet on that rate.

Finding the winner

A script, when the height of end contest is reached will call a function that will query the WAVES/USD Oracle and find if is there a winner.


Each week, half of WAVES fees that are generated by the WAVES granted by waves team will be added to the DAPP Jackpot.

If there is no winner, the prize will be brought forward to the next contest
