Solana_NFT_Oracle

An oracle for solana NFTs, it uses magicEden and Opensea to determine the floor prices of NFTs.

it also can use other marketplaces like SMB.

this is how it works:
-the oracle gets the floor prices from the available market places
-the oracle gets the prices of solana and ethereum (the price on opensea is denominated in ethereum and on magiceden in solana), there are a few checks to see if the price got from the providers (mostly coingecko and coinmarketcap) is valid and true
-after that the floor price is determined and confronted with the old price saved in the db, if the old price in the bd has more than 2 percentage price difference between the old price and the new price, then the price is changed by 2%, this is done to prevent washtrades
-if for some reason some part of the oracle stops working then the old price is used, if the price is 20 minutes or more old then there is a telegram bot message to inform that the oracle is not working
