Exchange rates for each supported asset are an integral part of the Tectonic protocol, as they are used to determine the collateralization ratio and all other functions that require inter assets value determination.
Price Feed
Exchange rates of all supported assets on Tectonic are maintained through Tectonic's internal price feed, which which source these prices from multiple data sources consisting of centralized and decentralized exchanges.
In the future, it is possible to replace or supplement the existing price feed with any other decentralized oracle protocol. The Tectonic team will revisit this issue from time to time and provide updates as price feeds from other price oracles become available on Cronos.
