Fetch Real-Time Asset Prices Using On-Chain Data

[gemcoder21]

Description

Replace reliance on centralized APIs (CoinGecko, CoinMarketCap) with on-chain data sources for real-time asset prices. This improves decentralization, reliability, and data accuracy.

Approach

• Use on-chain oracles (e.g., Chainlink, Tellor, Pyth).
• Query DEX price feeds (Uniswap V3 TWAP, Sushiswap, Curve, Balancer).
• Ensure data validation and handle potential failures.

Requirements

• Fetch real-time prices for major assets.
• Support additional assets easily.
• Ensure accuracy and reliability.

Data to Collect:

• provider, asset_id, price, price_change_24_hours (or calculated based on history), date ?

Ideas

pub trait PriceChainProvider {
    fn get_chain_prices(&self, chains: Vec<Chain>) -> Result<Vec<AssetPrice>, Error>;
}

pub trait PriceChainAssetsProvider {
    fn get_asset_prices(&self, chain: Chain, asset_ids: Vec<AssetId>) -> Result<Vec<AssetPrice>, Error>;
}
