Oracles
Kwenta price updates explained
Kwenta utilizes the decentralized Chainlink oracle network which provides up-to-date token prices data to smart contracts on Ethereum.
Responsibilities of an oracle
- Updates, stores, and distributes up-to-date token prices relevant to the system.
- Disables exchange functionality if prices are not fresh.
- Provides functionality to perform exchange rate conversions between synth flavors.
Currently, Kwenta utilizes the Synthetix protocol and its respective
ExchangeRates contract to retrieve frequently stored price updates.At Synthetix, the on-chain manifestation of the oracle is the
ExchangeRates contract, whose stored prices it frequently updates. The primary user of these prices is the Synthetix contract, which needs them to calculate debt allocations when issuing and burning synths, and to determine the correct quantity of synths when performing an exchange of one flavour for another.Contract | Description |
|---|---|
Oracle | 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. |
ExchangeRates | The Synthetix exchange rates contract which receives token prices from the oracle, and supplies them to all contracts that need it. |
