[MRC-70] NTRN Price Feed Migration


The objective of this proposal is to migrate from the current TWAP-based NTRN oracle implementation to a standard Pyth price feed.


Currently the NTRN price feed is calculated as follows:



  • NTRN/ATOM uses a 30 minute geometric mean TWAP from the NTRN/ATOM XYK pool on Astroport.
  • ATOM/USD is the ATOM Pyth price feed.

Since the NTRN feed is now available from Pyth, we propose to migrate to a standard Pyth feed as follows:


This migration has the following advantages:

  1. It’s simpler, as it doesn’t require a custom price feed composed of a TWAP and a Pyth feed.
  2. It’s potentially more robust, as now the price incorporates information from many sources, including several CEXes, while previously it only depended on the Astroport XYK pool.
  3. It helps with standardization, as most of Mars prices are standard Pyth price feeds.


As stated before, we believe this migration potentially improves the robustness of the feed. However, if anything negative were to happen specifically to the NTRN/USD Pyth price feed, such as bugs or manipulation, the protocol could be exposed to negative outcomes.


This is a signaling proposal, not an executable proposal.

The Mars smart contracts on the Neutron chains are currently controlled by the Builder Multisig address. If this proposal passes, the builders will utilize their multisig to make the necessary parameter changes.
