Because stablecoins are almost always pegged to a target price, it is ideal for them to revolve around that price. Most stablecoins are pegged to 1 USD or another fiat currency (like Japanese Yen, Chinese Yuan, etc.).
However, ARTH is fully pegged to ETH growth, which makes it highly liquid and resistant to central failures. For simplicity purposes, ARTH's initial price was set at 2 USD worth of peg, signifying the rise in inflation, among other things.
The goal of this peg is to achieve stability whilst at the same time slowly appreciating in value.
In various simulations, it was found that the pegged value remained relatively stable in moments when the market turned bearish but started to appreciate ever so slightly whenever the market turned bullish.

The basic idea of Peg is to capture the appreciation of an underlying asset without causing too much volatility. In this case, the underlying asset is ETH.
To do this, it uses two moving averages. A 7-day moving average to understand the short-term price trend of the underlying asset (which is mainly used to understand when to stop the appreciation). And a 30-day moving average is used to understand the long-term price trend of an underlying asset (which is mainly used to understand how much to appreciate the price).
If both the 30-day and 7-day moving averages are in an upwards trend, then the indicator appreciates the peg by a fraction of the appreciation of the 30-day moving average.
The above code snippet represents the logic of how the peg is calculated. It uses the following variables.
pricesShortTerm: A price feed that is used to represent the short-term trend of the underlying asset. In the current deployment, we use the 7-day moving average of the ETH/USD price feed.
pricesLongTerm: A price feed that is used to represent the long-term trend of the underlying asset. In the current deployment, we use the 30-day moving average of the ETH/USD price feed.
startingPrice: A starting price for the indicator. In the current deployment, this is set to 2$
dampeningFactor: A dampening factor that dampens the indicator. A high dampeningFactor will cause the peg to capture more of the underlying collateral's appreciation. Vice-versa, a low dampeningFactor will cause the peg to capture less of the underlying collateral's appreciation. In the current deployment, the dampeningFactor is set at 10%.
The appreciation of ARTH is paid for by those who deposit collateral into the protocol. This means whenever ARTH appreciates against the US dollar, collateral providers who have opened loans and deposited collateral need to ensure that they are able to pay back their loan with the principal plus the appreciation (which behaves a bit like an interest fee).
Yes.
While loans and lending protocol for ARTH is set to have 0% borrowing fees, the appreciation of ARTH behaves like an indirect interest fee or tax.
But since ARTH only appreciates if the underlying collateral appreciates, borrowers (in most cases) don't have to do anything if they are already exposed to the underlying collateral. Because ARTH appreciates at a fraction of how much the underlying collateral appreciates, the borrower still realizes a net gain even after paying for ARTH's appreciation.
The peg can be influenced by only two major factors
Incentives via Governance: Governance can decide to incentivize users who deposit a certain type of collateral, thereby influencing the collateral compositions of ARTH.
Appreciation of the underlying collateral: ARTH's price is influenced by its underlying collateral (ETH)
