To monitor MATIC’s live price feed, Dfyn will use the MATIC oracle provided by ChainLink. We decided to go with ChainLink’s oracle since it is fully decentralized, provides reliable data and has a robust security mechanism. Furthermore, the ChainLink team has agreed to accommodate our request for a faster price feed by providing a custom feed that allows Dfyn to query the most recent MATIC price every 5 seconds.
No, once you enter a position, you can not make any changes to it since the funds are locked in the contract.
Yes, 3% of each round’s total pool will be credited to the Dfyn treasury. This fee will later be used to buy back DFYN.
Note: The fee percentage is subject to change.
For each round, the payout is calculated using the following formulas:
Payout Ratio for the BULL Pool = Prize Pool ÷ TVL in the BULL Pool
Payout Ratio for the BEAR Pool = Prize Pool ÷ TVL in the BEAR Pool
For example, if 1500 MATIC is locked in the BEAR pool, and the overall prize pool is 4500 MATIC, the BEAR payout ratio will be (4500÷1500)=3x, and the BULL payout ratio will be (4500÷3000)=1.5x. The following formula gives the payout received by each winner:
Payout Amount = Payout Ratio × Value Locked× (1 — Treasury Fee)
In the above case, if you entered a BEAR position with 200 MATIC, and the round ends in a BEAR result, you would get a payout of (3*200) × (1–0.03) = 582 MATIC (assuming a fee of 3%). Your profit would be 352 MATIC (582–200).
In such an event if the round ends with the position that the users entered, their locked funds are returned to them (minus the fee). However, if the round ends with the opposite position, the funds will be credited to the treasury.
In such an unlikely event, no one will be regarded as the winner, and all the locked funds will be transferred to the treasury.
This error occurs when there are some syncing issues with Dfyn's Graph node. If you get this error, there is no need to worry. It will get resolved on its own within a few minutes.
A round may sometimes be cancelled due to some technical issues. If you had entered any funds in a round which is later cancelled, they will be returned to you without the deduction of any fees.
