Implementation Details: Briefly describe how the oracle is integrated into your project:

The oracle is used to obtain a price feed for each stablecoin that is used to mint mUSD, and thus provide slipageless mints and trades between underlying assets.

https://docs.mstable.io/developers/contracts

forkedFrom (Does your project originate from another project):

None.

methodology (what is being counted as tvl, how is tvl being calculated):

We are counting the assets backing mUSD as the tvl, since mUSD is backed 1:1 with other stablecoins on Sui, in direct relation to the price of these assets when minted.

Github org/user (Optional, if your code is open source, we can track activity):

None.
