ARC: Add support for DeFi Pulse Index (DPI)

Hey Mark :wave: Greg from Set Protocol & Index Coop here!

Small note to add here :slightly_smiling_face: DPI indeed does have a Chainlink price feed: Etherscan.

Thanks. I’m in support.
DPI has a track record and most of its constituents are blue-chips that are already in Aave.

Glad to hear ChainLink integration is done

Concerns:
-Adds to systemic risk (objective: tokensets contracts, subjective: sanity of index management decisions), but I suppose this can be mitigated as outlined per the OP.
-Liquidation: would Aave be able to promptly liquidate DPI collateral in case of a market crisis when there’s no liquidity on secondary markets? Redemption of DPI on Set means additional costs to the liquidators which may make it economically inexpedient for them to engage in. Would love to see the track record of the Concourse arb bot. LTV of 50% makes sense with the above in mind.

Hey AAVE fam! BigSky from Index Coop here. We are really excited to see this proposal moving forward. Adding $DPI as collateral will be a huge win for both protocols.

This is a good question - do you see liquidations as $DPI > ETH or $DPI > Components > ETH? In my eyes adding that extra step is not necessary but I may be missing something. At the end of the day - the DPI <> ETH LP on Uniswap is >$60 million and the underlying tokens are all highly liquid. This should lower liquidation concerns.

Thanks for your detailed proposal @LemonadeAlpha. I really like the idea of adapting the Concourse arbitrage bot for liquidations/redeems

Could you elaborate on DPIs Token (& Protocol) permissions (minting) and upgradability. Is there a multisig? What can it do? Who are the signers?

I was also wondering what is the security margin parameter? is it the reserve factor?

Do you have some technical and financial analysis on DPI to support the parameter calibration :owl:

Thanks for the questions @Alex_BertoG :raised_hands: taking those one at a time:

  1. Is there a multisig? Yes
  2. What can it do? The multisig is responsible for initiating rebalances, performing meta-governance, adding / removing new protocol functionality (e.g. intrinsic productivity). It does not have the ability to arbitrarily move underlying assets, mint tokens, etc.
  3. Who are the signers? The signers are currently members of the Set team with the intention to add Index Coop community signers over time.
  4. I was also wondering what is the security margin parameter? is it the reserve factor? Set Protocol took inspiration from the Uniswap market documentation, where they utilize a security margin which is added to the loan to value and liquidation threshold to further protect the protocol.

Please lemme know what further questions come up!

DPI

The DeFi Pulse Index (DPI) is an index product managed by Index Coop. At the time of writing there are 324,355 DPI in circulation. DPI was audited by OpenZeppelin in September of 2020, launched early October 2020, and has over 111,000 user transactions.

DPI Smart Contract Risk: C-

DPI was audited by OpenZeppelin in September of 2020, launched early October 2020, and has over 111,000 user transactions.

DPI Counterparty Risk: C

DPI is a product whereby holders of DPI have no metagovernance influence on Index Coop or the protocol within the index. DPI trades on the ethereum network and inherits the trust of the network much like USDC. DPI has over 12,055 holders and the DPI-ETH pool is Uniswap’s 17th largest at $90M. Anyone can Mint, Trade and Redeem DPI.

The DPI utilises TokenSets V2 smart contract has been audited by Open Zeppelin audit [September 4th, 2020] which identified privilege roles in many of the contracts. The key findings are highlighted below:

  • The Controller contract has an owner that chooses the contracts that comprise the system. This includes all of the modules, resources and the factories that can be used to make Sets.
  • The IntegrationRegistry tracks third party integrations that can be used in the system. It also has an owner that can add, remove and edit the integrations as desired.
  • The PriceOracle has a list of oracles and adapters that can be used to retrieve third party prices. It also has an owner role that can choose the supported oracles, adapters and price pairs.

DPI Market Risk: B-

DPI’s price tracks the Net Asset Value of the underlying assets, by holding a basket of protocol tokens the volatility of a single asset is dampened. This is reflected by DPI having a standard deviation of 5.75% since exception compared to ETH and AAVE which has a standard deviation of 5.03% and 7.79% respectively over the same time period (03/10/2021 to 01/05/2021). When considering liquidity, the average daily trading volume is $7.19M, based on over a trailing 90 day trading period. However, DPI holders have the option to mint/redeem the underlying tokens within DPI which draws on the liquidity of the underlying assets and also allows for any deviation from NAV to be arbitraged away by traders.

30 Day Average Daily Volume: $7.29M
90 Day Average Daily Volume: $7.19M
1 week Normalised Volatility: 0.05379
1 month Normalised Volatility: 0.05535
3 month Normalised Volatility: 0.05035
6 month Normalised Volatility: 0.05812
1 year Normalised Volatility: 0.05845

Risk Parameters:

LTV 60%
Liquidation Threshold 70%
Liquidation Bonus 10%
Reserve Factor 20%

UOptimal 50%

While the multisig can’t arbitrarily move assets, it theoretically could rebalance assets into a fake token. My understanding is, if control of the multisig is compromised all funds could be drained from DPI (let me know if this is incorrect!)

Hi Aave Community :wave:

Index Coop create a PR for listing DPI and it can be found on Github here. We would be greatly appreciated if we can get some feedback on the PR and then we can proceed to start preparing the AIP.

If we need to present the AIP & PR together for Aave’s review, please do let us know and we can proceed with the AIP. Looking forward to receiving feedback from the Aave team. :slight_smile:

Hi @Alex_BertoG

We have updated our PR and the parameters can be found here and the AIP description here.

We are really looking forward to using DPI on Aave V2 Markets.

Blockchain at Berkeley is in strong support of adding DPI as a collateral asset - excited to see how Index Coop will continue to contribute to the Aave ecosystem!

I’d be more in support of adding DPI to the AMM market. It has good liquidity and in my opinion the AMM market is a better fit for index like derivatives.

Hi @Emilio

If DPI was added on Aave V2, then Index Coop has the ability to create DPI2x-FLI. A product like this could generate substantial TVL for Aave. ETH2x-FLI is a $46M product during a quiet period in the market and was a $130M product during mid May 2021. This is a sizeable amount of TVL upside for Aave to miss out on. There is a first mover advantage for capturing future opportunities here and we would love for Aave to grab that opportunity with both hands :slight_smile:

We have an active snapshot poll happening today, finishing midnight 23/07/2021.

https://snapshot.org/#/aave.eth/proposal/QmaxUK1TejG5YQ1wpjSt8qTqdDNQsDu3JAx8Mr51MArmYR

It would be greatly appreciated if people can show support for getting DPI listed as collateral on Aave by heading across and voting in favour of the proposal.

Thanks @MatthewGraham, why wouldn’t the DPI2x be possible on the AMM market? Afaik to do that you would need to borrow stablecoins and marketbuy the underlying index assets to mint more DPI for additional leverage. The AMM market has decent liquidity and will for sure grow substantially as more demand is generated (it had a total of > 50M in stablecoins when its TVL was 500M). I personally don’t feel comfortable adding more collaterals to the Aave main market right now, because borrowing power on additional assets greatly increases the systemic risk and i would prefer until the next protocol iteration is out to expand on collateral types for the main market (next protocol iteration will have a lot of risk management features).

With that said, i see the AMM market as the perfect place to bootstrap liquidity (btw, there is a proposal up to add the DPI/ETH/WBTC balancer V2 shares on the AMM market, here Renew the AMM Market assets)

Hi @Emilio,

Introducing DPI as collateral on the Aave AMM is great :slight_smile:

But, looking at the stable coin liquidity on the AMM platform, it is a lot less than V2 and I don’t believe there is sufficient liquidity to support a FLI product. It might be that we need to wait for the next iteration to be released for the main market. :cry:

I believe Index Coop will also need to rework the AIP to reflect the changes from V2 to the AMM and there is not a lot of documentation out there on that. Please do lets us know if this is the direction to move forward and we’ll amend our AIP.

@MatthewGraham please understand i’m not trying to gatekeep here - i actually invite the community to speak out loud on the matter. I think the AMM market will grow pretty quickly as demand grows, right now demand is drained up because all the assets went obsolete but if we list DPI + the LP shares that i proposed and soon also curve and sushi shares, i’m willing to bet this can become a multibillion dollar market in TVL.
If the technicalities are a concern, the process to list on the AMM market is exactly the same as listing on the main market, if that possibility is of your interest i can point out to the changes needed to do that, changes are pretty minimal (just different addresses)
