Fate Protocol: Bull/Bear Coins as Native Oracles

I’m proposing to build Fate’s oracle system by turning bull and bear prediction pools into Chainlink-compatible price feeds that other DeFi protocols can use. This covers all five AOSSIE-defined tasks, along with a few practical improvements I identified while working with the codebase. For the core, I’ll implement IFateOracle with round-based price history and a sentiment-based price mechanism using multiple strategies like DIRECT, WEIGHTED, and EWMA. A FateOracleAdapter will provide Chainlink compatibility through AggregatorV3Interface. Since pools rebalance on every trade, each buy or sell naturally produces a new oracle data point. Alongside this, I’ll address some real issues I came across, like the hardcoded 18-decimal assumption that breaks certain pools, high RPC usage on the portfolio page, and fee accumulation that can’t currently be withdrawn. I’ll also add a subgraph for historical data, price impact estimation, and improvements to the explorer and creator dashboard, based on actual gaps in the current system.
