0xmahdirostsami · September 12, 2025, 5:41pm

**Hello guys,

is there any step-by-step instruction to how to create my own** PriceUpdateV2 account for SOL feed ID.

Where should get the needed input data?

You can find the price feed ID by searching for the asset here: Price Feed

Use the TS SDK for Hermes to do so, and the other TS SDK to post the updated data to a price update account or price feed account.

Then the Rust SDK for reading the prices from the account using PriceUpdateV2.
