Chainlink Oracle for UI Price Display

This section describes how the project's user interface (UI) uses Chainlink data oracles to provide convenient, real-time price information.

Role in the Ecosystem​

To provide users with a familiar and intuitive experience, the application's UI uses Chainlink Price Feeds. These industry-standard oracles fetch the current USD value of tokens used within the application, allowing for an informational display of staking balances and donation amounts in a familiar currency (e.g., "$10.50").

This functionality is for front-end purposes only and is entirely separate from the core smart contract logic.

Why Separate Oracles?​

The project uses two different types of oracles for two distinct purposes, which is a critical design choice for security and accuracy:

  1. Chainlink Oracles (for UI):

    • Purpose: Displaying USD-denominated values to the user.
    • Reason: Chainlink provides highly reliable, aggregated price data from many off-chain sources, making it the gold standard for general-purpose price information trusted by top DeFi applications.

  2. Uniswap Oracle (for Contract Logic):

    • Purpose: Calculating the on-chain token-to-ETH price for the give() function's burn calculation.
    • Reason: For core contract functions that move value on-chain, it is crucial to use a price source that reflects the actual on-chain liquidity and execution price. Using the Uniswap pool directly ensures that the burn calculation is based on the same market where a swap would occur, preventing any possible arbitrage or price discrepancies between off-chain and on-chain sources.
