[MRC-105] dTokens Listing

Summary

The objective of this proposal is to list the following assets as collateral on the Neutron outpost:

  • dTIA
  • dATOM

where dTIA and dATOM (referred to as dTokens) are liquid staking derivatives for TIA and ATOM, respectively, provided by Drop protocol.

Motivation

Drop is a cross-chain liquid staking protocol built as an Integrated Application on the Neutron network, it is a member of Lido Alliance.

dTIA and dATOM are liquid staking derivatives for TIA and ATOM, respectively, provided by Drop protocol. This allows users to effectively use a representation of TIA and ATOM across DeFi without sacrificing the staking yield.

We think these are really good assets to be used as collateral, as users would be able to use them within the Red Bank without sacrificing the staking yield. As such, we think they could generate considerable organic demand for the Mars Outpost on Neutron.

Furthermore, this listing would allow users of the Red Bank on Neutron to leverage stake TIA and ATOM, a popular strategy that gained significant traction. This further strengthens our conviction that this listing has the potential to increase activity within the Red Bank on Neutron.

Risks

In the sections below we’ll explore the risks associated with listing dTokens 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:

Centralization Risk:

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

Metric Requirements Comments
Owner Decentralization Ideal For the beginning, protocol ownership will be managed by the Neutron Subdao, which is effectively a multisig that is restricted to execute proposals unless they’re timelocked for 3 days during which they can be overruled (vetoed) by the Neutron DAO. It’s done to prevent the multisig misbehave without limiting it in execution.
Admin Decentralization Ideal See above
Other permissioned address Ideal Protocol operates permissionlesly besides two cases: 1. Neutron Subdao described above is able to pause the execution of different parts of the protocol with no timelock 2. There’s a rare corner case in a protocol behavior: if protocol wasn’t properly managed for ~6 days and slashing happened during this period, and this slashing impacted undelegations processed on behalf of protocol’s ICA, multisig will be involved to sort out batched undelegation request.

Oracle Risk

Pricing dTokens:

We propose the use of a custom oracle for dTokens that incorporates both the Drop redemption rate (RR) as well as dToken’s market price as follows:

dToken/USD = min(dToken /Token TWAP, dToken /Token RR) * Token/USD

where:

  • dToken /Token TWAP is the 30-minute arithmetic mean TWAP from the dToken /Token Astroport PCL pool on Neutron.
  • dToken /Token RR is the redemption rate of dToken according to the Drop contract deployed on Neutron.
  • Token/USD is the Pyth provided feed, used to normalize the price to USD.

This implementation achieves the following:

  1. It is robust to upwards price manipulation attempts since the price will always have a ceiling that is determined by the redemption rate. As such, even if the TWAP is manipulated, an attacker is not going to be able to reflect that into the price Mars uses.
  2. While downward price manipulation can still happen, it is mitigated by two factors. First, by using an arithmetic mean TWAP, which is more robust to downwards price manipulation attacks than a geometric mean TWAP. Second, given that dTokens won’t be borrowable, the scope of possible downwards price manipulation exploits are reduced to attacks that artificially decrease the price to make a certain position liquidatable. While this can happen, we believe it’s unlikely because: 1) the potential profits are lower than a pure price manipulation attack to steal assets (especially with Mars’s new auction-based liquidation mechanism); and 2) the risk is higher given that the attacker cannot guarantee that he’ll be the one performing the liquidation.
  3. It allows Drop to aggregate liquidity in more efficient pool types (PCL instead of XYK) where TWAP-based oracles by themselves (without the redemption rate) would not be robust.

For the above reasons, we believe the proposed oracle implementation for dTokens is robust.

Risk Parameters Suggestion

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

Parameter dTIA dATOM
Max. LTV 44% 62%
Liquidation LTV 45% 65%
Deposit Cap 50,000 dTIA 50,000 dATOM
Liquidation Parameters
Starting LB 0 0
Slope 1 1
Max. LB 0.2 0.2
Min. LB 0.05 0.05
Target Health Factor 1.05 1.05
Protocol Liquidation Fee 0.25 0.25
Reserve Factor 10% 10%
Usable as collateral? Yes Yes
Available to borrow? No No

Implementation

This is a signaling proposal, not an executable proposal.

The Mars smart contracts on the Neutron 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.

Is dATOM expected to have similar liquidity as stATOM at launch?
Noting that stkATOM has a cap of 25k with $2.3m liquidity and stATOM has the same cap of 50k with $3m liquidity, both provided in majority by the Cosmos Hub community pool.

This listing proposal seems to be a drastic change to the norm.

Hey Johnny, yes, we’re assuming dATOM will have similar levels of liquidity to stATOM at launch. Having said that, we’re going to closely monitor how liquidity evolves at and after launch and will adjust the caps if necessary.
