[MRC-71] axlWBTC Oracle Migration


The objective of this proposal is to migrate the axlWBTC feed from the currently used BTC/USD Pyth feed to the recently added WBTC/USD Pyth feed.


The motivation is simple. The asset that’s listed on Mars is Axelar Bridged WBTC (not BTC). As such, it’s more precise to use the WBTC/USD than the BTC/USD feed from Pyth. Furthermore, this reduces the risk surface for Mars related to dislocations to the underlying BTC represented by axlWBTC. While previously there were two sources from which this dislocation could emerge from, with this migration there will only remain one. These sources are:

  1. BitGo: WBTC is a representation of BTC in custody by BitGo. If anything were to happen to the underlying BTC, WBTC’s price would likely deviate from the price of BTC. Given that Mars currently uses the BTC/USD it wouldn’t be able to capture this eventuality. The new WBTC/USD feed, however, would.
  2. Axelar: axlWBTC is a representation of WBTC locked in the Axelar bridge. As such, if anything were to happen to the locked BTC, the price of axlWBTC could deviate from the price of WBTC. As Pyth currently supports WBTC and not axlWBTC, the protocol would still be open to this potential risk.


As stated above, we believe the proposed migration reduces the risk surface Mars is currently exposed to. However, Mars would still be exposed to potential issues at the Axelar bridge level.

Additionally, it’s worth noting that WBTC is significantly less liquid than BTC. As such, the WBTC feed could be more easily manipulated than the BTC feed. Having said that, at the current deposit cap levels, we don’t believe this to be a material risk for the protocol.


This is a signaling proposal, not an executable proposal.

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

Makes sense and obviously decreases risks if something were to happen to WBTCs backing. :+1:
