# Oracles The backing ratio between pool tokens and their underlying assets is maintained on-chain. For example, when 1 ySol is backed by 1.4 SOL, this 1.4:1 ratio is recorded on-chain. By multiplying this ratio by the underlying asset's USD value, Synatra obtains accurate USD pricing for its pool tokens. This mechanism, powered by [Switchboard](https://docs.switchboard.xyz/docs) oracles, enables seamless integration with DeFi protocols by providing reliable price feeds. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
