Offchain Price Oracle

Price oracle that shows liquidity-weighted average of spot prices of multiple dexes. The oracle can be easily manipulated inside transaction so it should ONLY be used offchain. See Examples section below.

Wrappers

Price Oracle handles wrapped tokens like WETH, cDAI, aDAI, etc. using custom wrapper smart contracts that wrap/unwrap tokens with latest wrapping exchange rate.

Connectors

As some tokens do not have direct liquidity pairs oracle uses connector tokes to find prices for such tokens.
