0x5A599251a359Cf27A6A42E7baB1b1494d3919083
Price feed contract (on Soneium), returns wstASTR/ASTR exchange rate in 8 decimals
Dev Notes
wstASTR Price Oracle Details
The wstASTR price feed, located at 0x5A599251a359Cf27A6A42E7baB1b1494d3919083 on Soneium network, is an exchange rate-based price oracle that provides the exchange rate between wstASTR and ASTR.
The latestRoundData() function returns the ASTR/wstASTR exchange rate as an int256 value (answer) with 8 decimal places.
The exchange rate is updated daily at approximately 12:00 AM UTC after claiming rewards from Astar Dapp Staking. For the remainder of the day, the exchange rate remains unchanged, as new rewards can only be claimed the following day.
Since the wstASTR staking logic is managed by a Vault contract on the Astar Network, which adheres to ERC-4626 standards, the exchange rate between wstASTR and ASTR adjusts once rewards are claimed. This update is reflected in the price feed contract by timely updating the RoundData struct, ensuring that the returned exchange rate is accurate and up-to-date.
