[MRC-50] axlWETH Listing - Neutron Outpost

Summary

The objective of this proposal is to list axlWETH on the Red Bank’s Neutron Outpost.

Motivation

The main motivation for listing axlWETH is to allow users to perform delta neutral leveraged staking with wstETH, which we’re also proposing to list on the Red Bank. As mentioned on the wstETH listing proposal, leveraged ETH staking has been a significant growth driver for protocols on Ethereum, as evidenced by the fact that 51% of Aave V3’s TVL today is wstETH. As such, we believe listing this asset (along with wstETH) has the potential to catalyze activity within the Red Bank.

Additionally, it’s worth noting that axlWETH is currently the second most bridged Axelar asset from Ethereum to Cosmos and has consistently been one of the most liquid assets in the Cosmos ecosystem. This further strengthens our conviction in the popularity of this asset and its ability to generate valuable organic usage of the Red Bank.

Risks

In the sections below we’ll explore the risks associated with listing axlWETH and the proposed risk parameters for the listing.

Technical Risk

In terms of technical risk, the asset meets the minimum requirements suggested by the Mars risk framework:

Metric Requirements Axelar Network
Time Since Launch Ideal The Axelar Network has been live since February 2022. axlWETH has been live on Cosmos at least since May 2022.
Custom Public Audit Ideal The Axelar Network has had 27 public audits available here.
Recent Audit Ideal Several audits have been conducted within the last year.
Critical Vulnerabilities Ideal No critical vulnerabilities have been found.
Bug Bounty Ideal Axelar has a live ImmuneFi bug bounty program that covers up to $2.25m.

Centralization Risk

The Axelar Gateway contracts pose an important centralization risk for the asset. If the Axelar multisig that controls these contracts were to be compromised, be it via regulatory pressures, a hack/exploit or just multisig member misbehavior, the asset could suffer significant consequences that could translate into drastic repricings that may lead to protocol insolvency. While control over these contracts is expected to be handed to the DAO over the coming weeks, as of now it’s still under the purview of the multisig.

The following table summarizes the complete list of requirements and their status:

Metric Requirements Axelar Network
Owner Decentralization Ideal The Axelar Network itself is decentralized and governed by AXL holders. The AXL tokens are distributed over time to the core team, operators, investors, and community programs.
Admin Decentralization Not met The Gateway contracts custodying transferred assets are controlled by a multisig contract. Details of key holders are not published, however information about their team members can be found here. Since current affiliation of key holders is not known, this category is not met. In the future, the Gateway contracts are planned to be decentralized to the control of the Axelar Network.
Other Permissioned Addresses Ideal No other permissioned addresses.

Oracle Risk

We propose to use the Pyth ETH/USD feed to price axlWETH.

Note that this implementation uses the price of the underlying asset (ETH), rather than that of the bridged asset (axlWETH). This is important given that, if anything were to happen to the bridge (such as a loss of assets), Mars would effectively be unaware of it and would still be pricing the bridged asset as the underlying, opening the protocol to potential losses. This is a known but important risk. As such, we think the current implementation should be considered an interim one, as a more robust implementation that incorporates bridge proof of reserves is adopted.

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: 200 axlWETH
  • Interest Rate Parameters:
    • Optimal Utilization: 70%
    • Base IR: 0%
    • Slope 1: 5%
    • Slope 2: 300%
  • Liquidation Bonus: 10%
  • Reserve Factor: 10%
  • Usable as collateral? Yes
  • Available to borrow? Yes

Implementation

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.

Edit:
Revised the section titled “Liquidation Parameters” to reflect the accurate information pertaining to the current system in use on Neutron. The updated information is as follows:

Liquidation Bonus: 10%

This edit aligns with the existing old liquidation system on Neutron, ensuring accurate representation of the protocol’s mechanisms.
