Add DPI on Aave V2

Simple Summary

Add DPI as collateral support for DPI to the Aave market.

Abstract

Add DPI to Aave V2 market.

The DeFi Pulse Index (DPI) is a capitalization-weighted index that tracks the performance of decentralized financial assets across the market.

DPI is an ERC20 token that enables users to gain exposure to a basket of DeFi protocols via single transaction. The reduced volatility and broad diversification is a great property for collateral.

The index is weighted based on the value of each token’s circulating supply. DPI aims to track the projects in DeFi that have significant usage and show a commitment to ongoing maintenance and development. At the time of writing there are 14 tokens included in DPI.

Motivation

Aave would be the first major lending protocol to integrate an index product into its platform. DPI is becoming a DeFi standard and adding DPI would dramatically increase support for these efforts.

There are over 12,000 DPI holders and growing. Adding DPI as collateral would bring users into the Aave ecosystem allowing capital, yield and value to accrue to Aave participants.

Specification

DPI is a market capitalization weighted index product that follows a predetermined qualitative and quantitative methodology. The composition of the DPI portfolio is maintained by DeFi Pulse.

The DPI token has no governance characteristics and is predominantly traded via the V2 Uniswap DPI-ETH pool. DPI is supported and maintained by Index Coop and is built on TokenSets infrastructure.

At the time of writing, DPI has a market capitalization of greater than $220M and is the most readily traded DeFi index product.

There is an annual 95 basis point fee for holders of DPI that is split 70/30 between Index Coop and DeFi Pulse respectively.

DPI-ETH earns INDEX rewards through liquidity mining, currently yielding upwards of 20% APR, in addition to around 5% in trading fee income with limited impermanent loss.

Rationale

By purchasing DPI, users are able to gain exposure to leading DeFi protocols in the form of a single ERC20 token. The risk of holding just a select few protocols within a portfolio is diversified away, giving holders broad theme based exposure to DeFi.

With Aave currently making up 20.88% of DPI, there is no better way for Aave to support DPI’s widespread adoption, than to enable DPI being utilized for borrowing and lending. With DPI trading since October 2020 and 90 day average trading volume of around $7.2M.
