The upgrades to SynLev price calculator and price aggregator contracts have been live for over 2 weeks. Based on real world testing we can confrim these changes counteract the effects of bots abusing the Chainlink oracle system and improve the SynLev exchange for both traders and liquidity providers. As such we will now be reducing trading fees on all trading pairs. These fee changes are now live on

Trading Fee Reductions

  • 3X BTC/USD: 1% → 0.6%
  • 3X YFI/USD: 1% → 0.8%

Note: 3X YFI/USD carries a higher fee as it’s Chainlink YFI/USD feed deviation threshold is 1%…

SYN/ETH Uniswap LP staking is live at!

This is a short how to and explanation of how to stake your SYN/ETH Uniswap LP tokens for ETH rewards in addition to standard Uniswap fees. First it’s important to understand how normal SYN token staking works. Our new Uniswap LP program works in a very similar manner.

How it Works

First, nothing has changed with regards to how SYN staking works. We have simply set up a smart contract that has deposited 1 million SYN to stake and be shared between UNI LP providers. This amount can be increased or decreased but will always be displayed in the dApp at

SynLev X Chainlink

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…

To celebrate the recent launch of SynLev’s thirds asset 3XYFI/USD we are holding a 2 week long trading competition with a total prize pool of 70,000 SYN. Once the competition begins a live leader-board will be hosted at

Competition Period: 2021/1/15 12:00 to 2021/1/29 12:00 (UTC)

The top 11 addresses raked by effective 3XYFI/USD trading volume (in Ethereum) will share a pool of 70,000 SYN. The reward pool will be split among traders as follows.

  • First Place: 25,000 SYN
  • Second Place: 15,000 SYN
  • Third Place: 10,000 SYN

Chainlink Oracle Price Smoothing (100 Round)

Today we are introducing updates to the SynLev priceCalculator.sol and priceAggregator.sol contracts. The contracts are currently live Ethereum mainnet for testing and observation purposes only. They have been proposed to their respective proxies and must wait 48 hours before being fully implemented.

Goals of Upgrades

  • Curb the efficacy and profitability of bot “frontrunning” oracles or taking advantage of short term price volatility.
  • Decrease the “volatility decay” of bull/bear token price.
  • Reduction in gas costs.


This is accomplished by fundamentally changing how price is calculated. Instead of grabbing singular price data points for price calculation the price…

The SynLev Exchange has been live for just over a month and in that time we have seen over 154,000 ETH in trading volume, 718 ETH fees paid to SYN stakers, and 15 million SYN staked in the Syn Staking contract.

SYN Public Sale Price in ETH

The token sale has been delayed by 24 hours to 18:00 24 Dec (UTC) due to a technical issue.

We have received very positive feedback on our token sale proposal as laid out in our SYN token economic update. The community was happy with the reduction in the token sale allocation from 10 million SYN to 2 million SYN, and the progressive nature of the token sale price. Based on this response we will be continuing with token sale.

The token sale will take place on our platform at
