Liquidity-weighted dex price oracle for offchain price discovery
Spot Price Aggregator
The 1inch spot price aggregator is a set of smart contracts that extract price data for tokens traded on DEXes from the blockchain. To avoid price manipulations within a transaction, the spot price aggregator should ONLY be used off-chain. DO NOT use it on-chain. For off-chain usage see Examples section below.
Wrappers
To handle wrapped tokens, such as wETH, cDAI, aDAI etc., the 1inch spot price aggregator uses custom wrapper smart contracts that wrap/unwrap tokens at the current wrapping exchange rate.
Connectors
If no direct liquidity pair exists between two tokens, the spot price aggregator calculates rates for those coins using another token that has pairs with both of them – a connector token.
