# RedStone Brings Onchain Pricing to USDp & sUSDp

*Parallel stablecoins now have on-chain price feeds powered by RedStone, starting with USDp and sUSDp across Base, HyperEVM, Sonic, and Avalanche.*

This integration makes it easier for DeFi apps, especially lending markets, to support USDp and sUSDp with clearer, more robust pricing assumptions and safer risk parameters.

For the full governance context, see the [approved proposal](https://gov.parallel.best/t/pgp-33-l-launch-parallel-stablecoins-price-feeds-using-redstone/487).

**What’s included**
===================

Parallel uses RedStone to publish the following price feeds:

*   USDp / USD
    
*   sUSDp / USD
    

Deployed on:

*   Base
    
*   HyperEVM
    
*   Sonic
    
*   Avalanche
    

Why this matters
================

Stablecoins are only as useful as the ecosystem that can safely integrate them.

To list a stablecoin in lending markets (or use it as collateral), protocols need an oracle feed that is:

*   Credible (grounded in how the asset can be redeemed/valued)
    
*   Responsive (updates when conditions change)
    
*   Consistent across chains (especially for multi-chain assets)
    

That’s exactly what these RedStone feeds are built to provide. 

How the USDp / USD feed is calculated
=====================================

USDp / USD uses a “fundamental” approach:

*   USDp’s value is derived from its on-chain redemption price across all chains where USDp is deployed.
    
*   Redemption prices are aggregated across chains, and the median value is used as the final USDp/USD price.
    

In plain terms: rather than relying purely on external market venues, the feed is anchored to what USDp is actually redeemable for across its deployments, then uses a median to reduce outliers.

How the sUSDp / USD feed is calculated
======================================

sUSDp is a yield-bearing version of USDp, so its USD price is built from two components:

1.  USDp / USD (the fundamental price described above)
    
2.  The sUSDp-to-USDp exchange rate (sourced from the sUSDp contract on each chain)
    

So:

sUSDp / USD = (USDp / USD) × (sUSDp / USDp exchange rate)

Because the sUSDp exchange rate can differ across chains, sUSDp/USD is published per chain (e.g., Base, Sonic, HyperEVM, and Avalanche may each have their own sUSDp/USD value).

Update behavior
===============

To keep the feeds dependable without over-updating, the configuration is:

*   Heartbeat: updates at least every 12 hours
    
*   Deviation threshold: updates sooner if the price moves by 0.2% or more
    

This balances stability (less noise) with responsiveness (faster updates when it matters).
