Having non-correlated source of risk, so the movement at least do not correspond one-to-one, is better than having just one source of risk. - ETHGlobalOnline 2023.

Why does banks exist ? It’s because they offer multiple financial services. They keep money for savers but also can be lenders. What is BWise providing is similar to banking.

BWise is in the same time, making sure that your money is not going out of range of uniswap pools and thus, you are not been victim of impermanent loss but it is also using that extra amount of tokens that is recalibrated and not used anymore as a lending share, thus enabling you to earn yield thanks to SPARK technology with a stable coin.

To reduce fragmentation of Liquidity we have chosen to use SPARK technology by choosing DAI as a bridge currency. Every trade in our Auto-Rebalancing mechanism will include DAI/ABC pair. DAI is stable coin and participates naturally into reducing Impermanent loss.

"We have verified the formulas to calculate impermanent loss based on the latest ETH price history using the concentrated liquidity formula adopted in Uniswap v3".

- we have modified savingsDai contract to have a getLiquidityPosition that allows us to monitor DAI position in the monitor contract. 
- Spark contract are also deployed to Scroll (see #Scroll section)
