Ethereum

**Compound** is a [DeFi](https://iq.wiki/wiki/defi) project that enables users to take out loans or provide loans by locking their assets via [smart contracts](https://iq.wiki/wiki/smart-contract). It was built on the [Ethereum](https://iq.wiki/wiki/ethereum) [blockchain](https://iq.wiki/wiki/blockchain) and is governed by the [COMP](https://iq.wiki/wiki/comp) token.

# Overview  
  
The two primary users of the Compound platform are lenders and borrowers. Lenders can send their cryptocurrency tokens to an Ethereum address controlled by Compound to earn interest, while borrowers can post collateral in the form of cryptocurrency to borrow supported cryptocurrencies at a percentage of the posted value. [\[9\]](#cite-id-mvbpow0kx5)  
  
Lenders on the platform earn COMP tokens, based on the number of cTokens held in their wallet, which is proportional to the interest rate dependent on the available supply of that asset. If the market has more liquidity, the interest rate is lower. Users who lend assets to the protocol can take out a loan in any other cryptocurrency that Compound offers, up to the amount of collateral they have posted. [\[9\]](#cite-id-mvbpow0kx5)  
  
## Compound v2  
  
Compound v2 is a decentralized interest rate protocol that aims to create a foundation for future financial markets and applications. Running on the [Ethereum](https://iq.wiki/wiki/ethereum) mainnet, Compound v2 provides a system for lending and borrowing various digital assets. The protocol supports a range of assets, such as [ETH](https://iq.wiki/wiki/ethereum), [0x](https://iq.wiki/wiki/0x), [Augur](https://iq.wiki/wiki/augur), [BAT](https://iq.wiki/wiki/basic-attention-token), [DAI](https://iq.wiki/wiki/dai), and [USDC](https://iq.wiki/wiki/usdc), enabling users to participate in an environment with variable interest rates. [\[2\]](#cite-id-wvk4lhtjjg)  
  
## Compound III  
  
Compound III is an EVM-compatible protocol that enables the supply of crypto assets as collateral to borrow the *base asset*. Accounts can also earn interest by supplying the base asset to the protocol. [\[3\]](#cite-id-ibfmeaqds99)  
  
Users' collateral remains their property, safeguarded against withdrawal by other users, except in cases of liquidation. The first deployment of Compound III facilitates borrowing of [USDC](https://iq.wiki/wiki/usdc) by offering [ETH](https://iq.wiki/wiki/ethereum), WBTC, LINK, [UNI](https://iq.wiki/wiki/uni), or [COMP](https://iq.wiki/wiki/comp) as collateral. Despite the lack of interest earned on collateral, users can access increased borrowing capacity with minimized risks of liquidation and reduced liquidation penalties. Additionally, users benefit from lowered gas fees. [\[3\]](#cite-id-ibfmeaqds99)  
  
### COMP Governance Proposal  
  
The first proposal was for [USDC](https://iq.wiki/wiki/usdc) on Ethereum, and it created supply caps for five collateral assets and transferred 500,000 USDC controlled by Compound Governance into the market as initial reserves. Compound III was audited by [OpenZeppelin](https://iq.wiki/wiki/openzeppelin) and ChainSecurity, and formally verified in partnership with Certora. [\[4\]](#cite-id-8rn0m4kd19n)  
  
Compound III introduced a new model where each deployment featured a single borrowable asset. The collateral supplied by users remained their property and could not be withdrawn by other users, except during liquidation. [\[5\]](#cite-id-nqr7ly24kl)  
  
## Compound Treasury  
  
Compound Treasury, in collaboration with Fireblocks and Circle, developed a product and flow-of-funds that allows large holders of U.S. Dollars, such as neobanks and fintech startups, to access the interest rates available in the [USDC](https://iq.wiki/wiki/usdc) market of the Compound protocol. [\[6\]](#cite-id-p1gc6fpcwm)  
  
Accredited institutions have the option to borrow USD or USDC from Compound Treasury, using [Bitcoin](https://iq.wiki/wiki/bitcoin-btc), [Ether](https://iq.wiki/wiki/ether-eth), and supported [ERC-20](https://iq.wiki/wiki/erc-20) assets as collateral, at fixed rates starting at 6% APR. The borrowing term is open-ended, and no repayment schedule is imposed, allowing clients the flexibility to draw liquidity and repay balances at their discretion, as long as they maintain overcollateralization. [\[7\]](#cite-id-7f1bachhl05)  
  
# cToken  
  
cTokens are [ERC-20](https://iq.wiki/wiki/erc-20) tokens that represent the funds a user has deposited in Compound. When a user deposits [ETH](https://iq.wiki/wiki/ether-eth) or another ERC-20 like [USDC](https://iq.wiki/wiki/usdc) into the protocol, they get an equivalent amount of cTokens. For example, if a user locks up USDC in the protocol they will receive cUSD–tokens that automatically earn interest. At any time, cUSDC can be redeemed for normal [USDC](https://iq.wiki/wiki/usdc) in addition to the interest paid in USDC. [\[10\]](#cite-id-78yeen0oyci)  
  
cTokens were created in two original types: CErc20 and CEther. CErc20 wraps an underlying ERC-20 asset, while CEther simply wraps Ether itself. [\[10\]](#cite-id-78yeen0oyci)  
  
The Comptroller is the risk management layer of the Compound protocol; it determines how much collateral a user is required to maintain, and whether (and by how much) a user can be liquidated. Each time a user interacts with a cToken, the Comptroller is asked to approve or deny the transaction.[\[18\]](#cite-id-yqdhgg78b7o)  
  
## Liquidity Mining  
  
Liquidity mining refers to the mechanism by which a [cryptocurrency](https://iq.wiki/wiki/cryptocurrency) exchange platform can incentivize users who contribute to the platform's [liquidity pool](https://iq.wiki/wiki/liquidity-pool). When a user deposits a particular cryptocurrency on Compound, they receive the cToken version of the same in return. These cTokens can be used as collateral for a loan, meaning that users can spend funds while they’re earning interest. [\[1\]](#cite-id-f0itlvi75af)  
  
# COMP Token  
  
On June 15th, 2020 Compound made their governance token called COMP available for distribution. Compound began distributing 1,116,310.81 COMP across ETH, DAI, USDC, USDT, BAT, REP, WBTC and ZRX markets, proportional to the interest being accrued in each market. The proposal, which was passed by the community on June 14th, states: [\[11\]](#cite-id-s4d14uit71g)  
  
> "Within each market, half of the COMP is allocated to suppliers, and the other half to borrowers. Whenever an address interacts with a Compound market, it receives all COMP earned in that market, should it exceed a 0.001 COMP threshold"  
  
After one day of trading, the COMP token became the largest DeFi token by market capitalization overtaking [MakerDAO](https://iq.wiki/wiki/makerdao)'s MKR token after rallying over 60%. On June 16th, 2020 Compound’s market cap hit nearly $740 million.[\[12\]](#cite-id-b4sd7sk9d48)  
  
## Utility  
  
Compound protocol rewards its users with COMP tokens to distribute its operations. Anyone who owns COMP tokens can participate in decisions affecting the protocol, voting on proposals for the rules that govern the platform’s use. A COMP holder can also assign their voting rights to someone else to vote on their behalf. This means that someone who is not a COMP holder could be asked to vote on behalf of COMP holders when a particular issue arises.

## COMP Distribution  
  
When community governance first went live, the team explained how the total supply of COMP tokens would be allocated. Out of 10,000,000 total COMP, they reserved 775,000 tokens “for the community to advance governance through other means — which will be announced at a future date.” In September 2020, the team explained how those tokens are being distributed to the community: [\[14\]](#cite-id-7mdwpr9xd82)  
  
* In June, the team designated up to 500,000 COMP for distribution through Coinbase Earn. COMP tokens were available through Coinbase Earn until November 2021, at which point [Coinbase](https://iq.wiki/wiki/coinbase) transferred all remaining tokens to the Compound protocol’s Reservoir contract.  
* In September, they sent the remaining 275,000 COMP directly to the Reservoir contract.  
  
In total, 5,004,949 COMP are to be distributed to the community and this is over half of the total supply.  
  
In September 2020, the Compound team released the list of actions that were taken since the distribution of COMP began in June:  
  
* 15 governance proposals were created; 12 were implemented  
* A new interest rate model was developed by Dharma.io, and deployed for the DAI and USDT markets  
* The Augur team spearheaded risk management changes for REP, during the upgrade to REPv2  
* COMP token-holders voted to change the protocol’s price oracle to the Open Price Feed, an open-source project where a set of reporters sign price data that can be posted on-chain by any Ethereum address - and which doesn’t rely on the team  
* The community built an entirely new feature, market-level Borrowing Caps, to limit risk to the protocol  
* Autonomous Proposals were created, which allow anybody with 100 COMP to gather support for a Governance proposal  
  
## Coinbase Pro  
  
Coinbase Pro announced that they would be listing the COMP token on June 25th, 2020. Over 10% of the total supply of [USDC](https://iq.wiki/wiki/usdc), the [stablecoin](https://iq.wiki/wiki/stablecoin) created by Circle and [Coinbase](https://iq.wiki/wiki/coinbase), was locked on Compound. The announcement caused the market cap of Compound to spike around $2 billion dollars. After the announcement, but before the listing, the token price reached an all-time high of $371.

# Funding  
  
Compound has a total of four funding rounds with a total amount of $70.8 million. The project raised $8.2 million in a seed round, where lead investors included [Andreessen Horowitz](https://iq.wiki/wiki/andreessen-horowitz), [Bain Capital Ventures](https://iq.wiki/wiki/bain-capital-ventures), and [Polychain](https://iq.wiki/wiki/polychain-capital). They raised a $25 million Series A funding round, which was led by [Andreessen Horowitz](https://iq.wiki/wiki/andreessen-horowitz). They also received $1 million in USDC from [Coinbase](https://iq.wiki/wiki/coinbase)’s “USDC Bootstrap Fund.” In 2020, a Venture Round took place, and in 2022, a total of $37.6 million was raised through a Debt Financing round.

# X Account Hack  
  
On December 29, 2023, the X (formerly Twitter) account[\[19\]](#cite-id-7y4xxhgkk7w) for Compound Finance was hacked and for a short while was a fake phishing site, according to security-related X accounts Scam Sniffer and Officer’s Notes. During the hack, the account posted an advertisement for “free $COMP tokens,” urging readers to click a link provided. The link led to a website that looked identical to the protocol’s official website but was identified as a scam site. [\[20\]](#cite-id-j2ireppm1t)  
  
On Dec. 30, 2023, the account was recovered by the team, and the spam messages were deleted.  
  
> "The Compound Labs X account was compromised yesterday for \~4 hours until we regained control of the account and removed the spam messages. We have full control of the account again and appreciate the community for spreading the word yesterday until we regained access." - the team tweeted[\[21\]](#cite-id-zd9fr3i4srf)
