Constituent Contracts



The oracle is responsible for collecting and updating all token prices known to the Synthetix system. Although it is not a contract, it controls a known Ethereum address from which price updates are sent to the ExchangeRates contract.


The Synthetix exchange rates contract which receives token prices from the oracle, and supplies them to all contracts that need it.
