Developer | Add Methods to Parse Pyth Benchmark Prices on Aptos Contracts

About the Bounty

Your Mission:

Benchmark prices can be verified and consumed on the EVM chain using the [parsePriceFeedUpdates](https://docs.pyth.network/price-feeds/api-reference/evm/parse-price-feed-updates) method. Implement a similar method to use Benchmark prices on Pyth’s Aptos contract.

Implementation Suggestion:

The source code of the Pyth Aptos contract lives here https://github.com/pyth-network/pyth-crosschain/blob/main/target_chains/aptos/contracts/sources/pyth.move . Your goal will be to add a new function to its public interface that parses and return benchmark prices.

Consult the EVM implementation of the same method for a hint on how to implement this:

About:

The Pyth Network is a first-party financial data oracle network that delivers on-demand, low-latency price data for over 500 assets on nearly 50 EVM chains and another 10 non-EVM chains. As of today, there are about $5B in Total Value Secured by the Pyth Price Feeds and the latter has facilitated more than $400B in total trading volume across since inception.

Today's oracles are push oracles where the oracle operator is responsible for submitting price updates to the blockchain. Pyth is different: it is a pull oracle where anyone can update the on-chain price permissionless.

To learn more about Pyth, and Pull Oracles, please check the documentation here.

Submission Requirements:

• A pull request containing the implementation of this new function on Superteam website.

Grading:

• Douro Labs engineers (Pyth Network contributors) will review all codes submitted within five days of the submission deadline.

• The winner of this bounty will be selected based on how elegant and secure the code.

Bounty Prizes:
