Yearning For More Trading Pairs

3XYFI/USD is now SynLev’s third asset release, our first being 3XETH/USD followed by 3XBTC/USD, both of which are powered by Chainlink oracles and have been trading successfully for over three weeks. We have learned a lot over the past few months with regards to implementation of oracle- driven synthetic leveraged assets. We have also made some much needed protocol upgrades to further reward SynLev liquidity providers and improve trading for all SynLev users.

As such, we are ready to introduce our third trading pair 3XYFI/USD. For this asset we will not be offering early LP rewards. iInstead, initial liquidity will be provided by the dev team from the token sales fund. To kickstart trading, we will be running a 3XYFI/USD trading competition with a 70,000 SYN prize pool starting Jan 14. For more details check here.

The Importance of Oracles and Why SynLev Selected Chainlink

Chainlink oracles solve two inherent shortcomings of blockchains: connectivity to off-chain data and the security/reliability of that data to trigger high value contracts.

It is our policy at SynLev that we exclusively utilize the Chainlink Network in order to access essential information outside the blockchain such as price data without sacrificing on security and decentralization. Chainlink Price Feeds utilize the most secure oracle nodes, the highest quality data, decentralized aggregation, and provide on-chan transparency and strong crypto-economics to ensure the Price Feeds update during network congestion, all of which users can independently verify.

How Does it Work?

SynLev assets access price data from the Chainlink Price Feeds in order to calculate their leveraged asset prices. The assets are deployed in symmetrical pairs, one side of the pair acting as the “bull” token and the other side as the “bear” token. Both pairs react in an opposite and proportionate manner based on the underlying asset’s price movement: the bull token with the price and the bear token against it.

SynLev’s first asset was 3X ETH/USD BULL/BEAR tokens, followed by the 3X BTC/USD BULL/BEAR tokens. Now a third 3X YFI/USD BULL/BEAR token pair also powered by Chainlink, with price data supplied via the YFI/USD Price Feed. We plan to continue launching more assets supported by Chainlink in the future based directly on demand from the Synlev community.
