[MRC-91] WBTC (Native) Listing - Osmosis Outpost


The objective of this proposal is to list native WBTC on the Osmosis outpost of the Red Bank.


Axelar WBTC has been listed on the Osmosis outpost of the Red Bank since launch. Since then, it has been organically used within the protocol. The objective of this proposal is to launch the native version on Mars, which we hope can promote further use of the asset within the protocol.


We propose to use the WBTC/USD price feed from Pyth.

Risk Parameters Suggestion

Following the methodology suggested by the Mars Risk Framework, we propose the following parameters:

  • Max. LTV: 78%
  • Liquidation LTV: 80%
  • Deposit Cap: 20 WBTC
  • Interest Rate Parameters:
    • Optimal Utilization: 60%
    • Base IR: 0%
    • Slope 1: 10%
    • Slope 2: 300%
  • Liquidation Parameters:
    • Starting LB: 0
    • Slope: 1
    • Max. LB: 0.2
    • Min. LB: 0.05
    • Target Health Factor: 1.05
    • Protocol Liquidation Fee: 0.25
  • Reserve Factor: 10%
  • Usable as collateral? Yes
  • Available to borrow? Yes


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.

Can we also please list wstETH (Osmosis outpost)?

Hey @marty - interested in how you plan to utilise wstETH in Mars V2 - it’s on the Neutron outpost already, and the liquidity is better on the Neutron outpost, the deposit cap would be relatively small with the current liquidity levels on Osmosis - but could be worth considering.

Enabling wstETH could mean we can also enable high leverage staking on the wstETH-WETH pair, however the borrow cost of ~4.5% on WETH rn doesn’t really make this profitable

Hey @dancreee, thanks for the response. I am sorry it took me so long to come back to this.

I use ETH on Mars v2 Osmosis outpost as my main collateral to borrow stables against. It’d be great to be able to use wstETH for the extra yield. Osmosis is where most of the stablecoin liquidity is, where the liquidity is for most of the assets I trade (wBTC, AXL, TIA, etc), also the borrow rate for stables is much less volatile compared to Neutron. I’d like to be able to swap the ETH I am currently using as collateral in my credit account to wstETH without having to withdraw/unwind/bridge it to a different chain first for UX reasons. I understand that the wstETH liquidity is still a bit behind Neutron’s, but the Osmosis pool / incentives are relatively new & liquidity has been growing fast. I am sure it’d be a popular collateral asset & no harm starting with conservative caps if the risk framework calls for it, right? Thank you for the consideration.

This proposal to list wBTC (native) passed governance on March 30th.
Why has the builder multisig not made the parameter change after all this time?
