HackMoney Hackathon 

Compound Grants is sponsoring the upcoming HackMoney hackathon, which will run from June 18th to July 9th. This event will bring together 1,000+ builders and designers to create innovative new financial products, learn from some of the sharpest minds in DeFi, and compete for $150k in various prizes. 

If you’re looking for inspiration and/or guidance on what to build, Adam Bavosa hosted a workshop for Building on the Compound Protocol on June 15th, which you can watch a recording of here. We look forward to seeing the innovative projects and products launched during the hackathon!

Pendle Launches on Mainnet

Pendle, a protocol for hedging future yield, officially went live on June 17th. At launch, Pendle will support cDAI powered by Compound and aUSDC powered by Aave. Users can supply cDAI and aUSDC to Pendle’s protocol, in exchange for ownership tokens (OT) and future yield tokens (YT). By separating the yield and ownership characteristics of cTokens, traders can express their views on the future increase or decrease of interest rates in a more capital-efficient manner than having to purchase the underlying asset. For a deeper explanation of Pendle and a list of use cases, check out their documentation.

Governance Updates

Since the last newsletter, Proposal 47 is in the active voting stage and Proposal 48 was canceled and will be resubmitted as Proposal 49.

In Progress Votes

Proposal 47: Oracle Improvement

  • Status: Active: 1 day, 23 hrs left

  • Proposer: Getty Hill (CAP)

  • Voting Results: 662,442 For and 0 Against

  • Summary: Proposal 47 replaces Coinbase with Chainlink as the main reporter for Compound’s price feed. The Chainlink prices will be validated against the same Uniswap Anchored View contract as the current oracle system, with a deviation threshold of 15% instead of the current 20%. You can view this visual representation of how the Uniswap Anchor flow works for the BAT/USD market. As a failsafe, the system also allows the community multisig to switch a market’s primary oracle from Chainlink to Uniswap V2. Getty and the Chainlink team have performed a number of tests and analyses on the new price feed and commissioned Trail of Bits for an audit. Getty also created a website that compares the current price data with the new Chainlink implementation and the standard Chainlink implementation, as a sanity check to show that prices are being posted as expected. Community members like Getty Hill have been championing the switch to a new price feed since January, with the goal of improving the protocol’s overall security and ability to support a wide variety of new assets. The price feed is crucial to Compound’s safety, and all COMP token holders are encouraged to deeply review the deployed contract, original forum post, and Trail of Bits Audit Report before voting.

Proposal 48: Update and Standardize cToken Implementation

  • Status: Canceled June 16th, 2021

  • Proposer: Geoffrey Hayes

  • Voting Results: NA

  • Summary: Proposal 48 updates the cToken implementation for COMP, DAI, LINK, TUSD, UNI, USDT, and WBTC, all of which are the newer, upgradable markets. The proposed upgrade merges the delegate function into the base cToken implementation, as well as takes 2.8% of the liquidation discount and transfers it to the cToken reserves, reducing the effective liquidator incentive to the historical baseline of ~5%.  The goal of the additional transfer to reserves is to help protect the protocol against the risk of insolvency due to cascading liquidations. As explained in the accompanying forum post, this patch is the first in a series of minor upgrades from Compound Labs that will improve the overall security and gas efficiency of the protocol. Proposal 48 was canceled during the review period and will be resubmitted shortly, as a community member noticed a potential improvement to transaction event logs.
