About the Bounty

Your Mission:

As of today, only developers using Pyth in Rust language can easily combine 2 Pyth Prices into 1 (SOL:USD/ETH:USD=SOL/ETH).

The goal of this bounty is for you to create a Math Library to combine Pyth prices in Solidity.

For reference, you can start reviewing the Math Library used by Rust-based applications here.

Implementation Suggestion

Add your solidity library to the pyth solidity SDK here https://github.com/pyth-network/pyth-crosschain/tree/main/target_chains/ethereum/sdk/solidity

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 close to 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.

Most oracles today 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 permissionlessly update the on-chain price.

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 5 days of the submission deadline.

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

Bounty Prizes:

• The developer with the best/selected code will be rewarded with 1,000 PYTH
