[MRC-93] stTIA HLS Market


The objective of this proposal is to launch the stTIA High Leverage Strategies (HLS) market with TIA as debt asset and stTIA as collateral.

A Review of HLS

Mars credit accounts are highly flexible and allow for a number of yet unexplored use cases to be implemented. HLS are one of those use cases. In essence, HLS are a type of credit account that allows users to take high leverage on a particular subset of assets by restricting the asset the debt of the account can be denominated in. The reason this is possible is that all assets within a HLS market should be highly correlated with the debt asset of the account and as such, the risk of offering high leverage for those assets is significantly lower than on a generalized credit account.

HLS markets are defined by a single debt asset and a set of collateral assets that can be used with high leverage within that HLS market.

The creation of these markets will allow users to use the LSDs and stablecoins listed above and borrow the whitelisted assets for each market with up to 10x leverage. We expect this additional efficiency to open up new use cases within the Red Bank and further promote organic borrow demand.


The implementation of this proposal comes with two new types of risk:

  1. Smart contract bugs: There’s always the possibility of unforeseen implementation bugs and smart contract vulnerabilities. The materialization of these risks could translate into loss of funds for users. While the code being used has been audited, this obviously doesn’t guarantee that it’s free from bugs. As such, we suggest caution when using this new feature, especially within the first months of its implementation.
  2. Risk parameter-related vulnerabilities: If the risk parameters are set too aggressively, the liquidations system might not work properly which could translate into protocol insolvency. While we believe the proposed parameters are conservative enough, users should always have this risk present when using the protocol.
  3. Higher leverage means a greater likelihood of liquidation, which poses risk to users of the HLSs and to the Mars system (risk of bad debt if liquidations do not occur as expected/desired).

Risk Parameters Suggestion

  • Max. LTV: 90%
  • Liquidation LTV: 90.5%
  • Liquidation Parameters:
    • Starting LB: 0
    • Slope: 2
    • Max. LB: 0.2
    • Min. LB: 0.05
    • Target Health Factor: 1.05
    • Protocol Liquidation Fee: 0.25


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.
