# Oracle Gateway

The Oracle Gateway assembles the pre-trade price used by every swap in 03 steps:

* Step 1 - Blend and validate: Off-chain feeds (Pyth, Chainlink, Redstone) and an on-chain AMM TWAP are combined via a configurable weight. If the two sources diverge beyond disThreshold, the gateway halts trading until they reconcile, protecting the pool from contradictory or stale data.
* Step 2 - Apply bounded skewness: If the pool is imbalanced, the price shifts to nudge traders toward rebalancing. This incentive is capped at the fee level (V3 improvement over V2's unbounded skewness).
* Step 3 - Apply bid-ask spread: A fixed spread provides a baseline margin; a dynamic spread widens when oracle sources disagree, automatically increasing LP earnings during volatile periods.
