Risk Analysis per Asset

Stablecoins

BUSD

BUSD is one of the latest stablecoins launched by a partnership between Paxos, expert in stable coins, and Binance, one of the biggest exchanges and a major player in the industry. Aave is the first integration of BUSD in a DeFi money market, bridging our ecosystem with CeFi.

BUSD Smart contract Risk: C+

The BUSD contract launched in September 2019 has a small number of transactions, many transactions are likely to happen off-chain on the Binance exchange. However, Aave has performed a thorough verification of the smart contract that appears identical to the PAX smart contract launched in September 2018 with nearly a million transactions. Still, since the smart contract is so recent, BUSD cannot be used as collateral at present time.

BUSD Counterparty Risk: B-

BUSD is backed by real USD so it is centralised with a centralisation risk factor at D+ disqualifying it as a collateral. The administrative features are explicit with Paxos as custodian and issuer. A monthly audit attests to the consistency of the USD bank reserves versus the on-chain supply of USD. Finally, BUSD is compliant and has been approved by the New York State Department of Financial Services (NYDFS).

BUSD Market Risk: B+

The market capitalisation is quite high with a fast growth these last few months. The trading volume for BUSD has picked up with around $80 million a day, mostly but not limited to Binance. As a stablecoin backed by USD, the volatility is very low.

DAI

DAI is the first decentralised stablecoin built on the Ethereum network. It is minted by creating a Collateralised Debt Position (CDP) and staking a certain amount of ETH. Every CDP must be overcollateralised by at least 150% of the minted DAI. Below this threshold, the CDP gets liquidated.

DAI Smart contract Risk: B-

SAI is active since December 2017 and has remained fully operational. In November 2019 the contract has evolved for DAI to hold a basket of currencies instead of just Ethereum. Given its wide use in the DeFi space, the contract already holds over 2 million transactions which mitigates the risk rising from its young age.

DAI Counterparty Risk: C+

DAI is the stablecoin of Maker DAO which has been functioning efficiently since inception. Anyone can mint DAI by opening a CPD. The Maker team also has some control over the minting. Following the Black Thursday crash of March 2020, there was some deficit in the backing of DAI which required the minting of additional MKR. Additionally, there are some concerns related to the centralisation of the price feed, with oracles failing to keep the prices up to date during the said Black Thursday.

DAI Market Risk: B+

DAI has $200 million market capitalisation with over $15 million of average daily volume spread across the top exchanges. It has been robust throughout its whole life, sustaining multiple ETH price drops. The volatility is low, yet the DAI peg suffers regularly from high demand. Additional collaterals are since been added, among which USDC to stabilise the price.

SUSD

Synthetix is a decentralised synthetic asset platform on Ethereum that provides onchain exposure to real world assets. sUSD is the dollars pegged synthetic asset backed by the network token.

sUSD Smart contract Risk: C

sUSD was launched in June 2018 and has struggled to gain market share in the competitive stablecoin market with only a small number of transactions.

sUSD Counterparty Risk: C-

sUSD is built on a decentralised infrastructure but some security reports have highlighted undocumented functions in the Synthetix contracts that might present a security risk. With a centralisation factor at D+ sUSD cannot be used as collateral.

sUSD Market Risk: B-

Right now, there isn’t much liquidity available for sUSD on the market and the usage within the DeFi workspace is pretty limited with a small market capitalisation. As a result, sUSD has suffered a manipulation on the Kyber exchange resulting in its price rising up to 2.45$. Most of the time though, its value is stable around 1 dollar backed by the Synthetix Network Token.

TUSD

TrueUSD is supported by the company TrustToken, which is periodically audited by 3rd parties. Right now, TrueUSD’s usage and diffusion in the DeFi space is limited. Still it is supported by multiple centralised crypto lending operators.

TUSD Smart contract Risk: B

TUSD is active since May 2018 with this contract deployed in January 2019 holding over half a million transactions.

TUSD Counterparty Risk: C+

As it’s backed by real US dollars, TUSD is centralised. The technology to mint new TUSD against USD is open source and you can check in real time the proof of funds in an escrow bank account.

TUSD Market Risk: B+

TUSD is widely available in different exchanges with a high volume and market capitalisation. It is a low volatility stablecoin backed by real USD.

TUSD has recently updated their contract without proper audit. To limit the risk to the protocol the LTV has been temporarily reduced to 1% on the 19/06/2020.

USDC

USDC is primarily promoted by Coinbase and supported by the CENTRE consortium. Together with DAI, it has been the most used stablecoin in the DeFi ecosystem following a strong push from Coinbase who provides liquidity to projects.

USDC Smart contract Risk: B+

USDC has only been active since September 2018 with already nearly two million transactions.

USDC Counterparty Risk: B

As it’s backed by real US dollars, USDC is centralised. The technology to mint new USDC and hold the backed USD is based on a legal framework. It is currently maintained by the CENTRE consortium which is a trusted entity in the ecosystem. Furthermore, USDC is the first regulated cryptocurrency bringing a lot of legitimacy to the space. Still, the infrastructure is based on the Ethereum blockchain where regulators have little power.

USDC Market Risk: A-

There is a high trading volume for USDC reaching over $800 million a day, with many pairs in multiple exchanges and a high market capitalisation. The token is used in multiple DeFi platforms both as collateral and principal. USDC is a stablecoin backed by real USD leading to low volatility.

USDT

Tether is the oldest USD backed stablecoin. It initially started as an independent currency built on the Omni blockchain, and progressively moved on the Ethereum blockchain, presumably to take advantage of the DeFi ecosystem.

USDT Smart contract Risk: A-

USDT is the first stablecoin in operation since November 2014 and on this Ethereum contract since November 2017. With nearly 20 million transactions, USDT is one of the most used coins.

USDT Counterparty Risk: C-

Tether is centralised, fully controlled by Tether Limited, which is in turn controlled by BitFinex. The procedure to redeem the underlying asset in exchange for USDT is also unclear.

There are multiple legal investigations on these two companies regarding USDT. Specifically, there has been accusation of illegally manipulating the price of Bitcoin using non backed USDT, as well as legal claims on the usage of the collateralised funds by both Tether Limited and BitFinex. This brings USDT's trust risk factor down to D+ disqualifying it as a collateral.

However, since the beginning of 2020, the company has tried to gain back some trust, disclosing an audit and appropriate collateralisation.

USDT Market Risk: A+

USDT is widely available in different exchanges and is the stablecoin with the highest volume. The value of USDT is stable around 1 dollar as it is backed by USD.

Other Assets

AAVE

Aave’s native token LEND recently migrated to AAVE to enable more functionalities, with the process ongoing.

AAVE Smart contract Risk: D+

The AAVE token was launched the 2nd of October with no deadline to migrate from LEND. The token is picking up with nearly 50k transactions and 5k holders.

AAVE Counterparty Risk: B-

Aave Protocol holds decentralisation as a core value, being fully open source. It is the token of the Aaave DAO fully governed by AAVE holders.

AAVE Market Risk: B-

The LEND markets have now migrated to AAVE which build volume fast while keeping a low volatility.

BAT

Basic Attention Token is an Ethereum based token that was created alongside its native platform, the Brave browser, with more than 5 million monthly users. BAT’s main use case is to reward publishers and content creators through tips on the browser, or as payment currency for the Brave advertisement system.

BAT Smart contract Risk: B+

BAT is in operations since 2017, the contract deployed in May holds nearly 2 million transactions.

BAT Counterparty Risk: B+

The platform is decentralised and the main product, Brave, is open source. It is based on a non-crypto native product, having managed to build a strong community with over 250,000 holders.

BAT Market Risk: B

BAT is one of the established projects on Ethereum and beyond the digital currency space, available on many exchanges with high liquidity. The token price has shown some volatility in the last year.

ENJ

Enjin aims to connect virtual worlds by empowering the management, minting and trade of blockchain assets. Enjin coin is the utility token of the platform and can be used as collateral to mint new digital assets in their standard ERC-1555.

Smart Contract Risk: B+

Enjin is active and traded since October 2017. It has nearly a million transactions.

Counterparty Risk: B+

Enjin is a decentralised protocol offering some open source permissionless products (wallet, marketplace, token minting). The community is quite large, with over 50,000 holders.

Market Risk: B-

ENJ has $200 million of market capitalisation and a decent amount of liquidity in big exchanges. Enjin has grown a lot in 2020 leading to high volatility in the price of the token (like the rest of the ecosystem).

ETH

Aave is developed on the Ethereum blockchain, making it fully dependent on Ethereum’s reliability. Aave and all the currencies presented are part of the Ethereum ecosystem; ETH is therefore the least risky currency considered.

ETH Smart contract Risk: A+

Ethereum is among the oldest cryptocurrencies ranking number 2 in terms of market capitalisation. It has a large and committed community as demonstrated by the 673 million transactions conducted.

ETH Counterparty Risk: A+

Ethereum is the most diverse ecosystem of digital currencies with nearly 100 million holders. There are many organisations that are dedicated to pushing the ecosystem further and decisions are community based.

ETH Market Risk: A-

Ethereum has among the highest market capitalisation and trading volumes of digital currencies. Ethereum’s price has been rather volatile in 2019, and prices of tokens on its ecosystem tend to be correlated (except stablecoins).

KNC

Kyber is an onchain liquidity protocol that can be used for a variety of inter-token use cases such as payments, portfolio rebalancing, currency exchanges. KNC, is mostly used for referrals and fee management. It implements a deflationary economy. Kyber is building protocol governance on top of the infrastructure based on the KNC token.

KNC Smart contract Risk: B+

Kyber is active and traded since September 2017. It has over 750,000 transactions.

KNC Counterparty Risk: B+

Kyber is a decentralised protocol, non-custodial and open source with over 50,000 holders.

KNC Market Risk: B-

Kyber’s decentralised exchange provides an important number of KNC token pairs with good volume (even on centralised exchanges) and decent market capitalisation. KNC’s price has been rather volatile with a recent spike driven by a new version of the protocol.

LEND

Aave’s native token LEND recently migrated to AAVE to enable more functionalities, with users, exchanges and markets slowly shifting.

AAVE Smart contract Risk: D+

The LEND token was launched in September 2017 to support ETHLend’s peer-to-peer loans and has been in existence ever since. At the moment it holds over 350 thousand transactions.

AAVE Counterparty Risk: B+

Aave Protocol holds decentralisation as a core value, being fully open source. The current governance process is based on voting of the team members which will progressively evolve into a DAO fully governed by AAVE holders.

AAVE Market Risk: C+

Since the mainnet launch of the protocol beginning of 2020, LEND has been growing fast affecting the price with some volatility but improving market metrics. The LEND markets have now migrated to AAVE.

ChainLink is a protocol that aims to provide a base infrastructure for decentralised oracles. The goal is to allow contracts to fetch data from the real world in a decentralised, tamper-proof manner. The use cases of LINK include payments of oracle fees and staking as a security mechanism to prevent tamper and fraud.

LINK Smart contract Risk: B+

ChainLink has been active since 2017 deploying this smart contract in September. Its adoption has boomed in 2019, driven by the reliability of its oracles, with now over 3.2 million transactions.

LINK Counterparty Risk: B+

ChainLink is non-custodial and opensource, with over 150,000 holders, hence presents low centralisation risk.

LINK Market Risk: B

LINK has become increasingly relevant becoming one of the most successful Ethereum projects. It is widely available on exchanges and increasingly popular on DeFi platforms. The trading volume is very high. LINK’s price has seen a sharp increase in 2019 and we can anticipate that the volatility will continue.

MANA

Decentraland is a virtual world on the Ethereum blockchain. Users are able to purchase land with the project’s token MANA, and the ledger is kept on the Ethereum blockchain, which indisputably demonstrates the ownership of the land. The virtual world just opened in February 2020.

MANA Smart contract Risk: B

MANA has been active since June 2017. It is a well-known currency, with nearly half a million transactions.

MANA Counterparty Risk: C

Decentraland is decentralised and completely open source, with over 35,000 holders. Some part of the protocol, such as the price oracle, hold some centralisation risk.

MANA Market Risk: C+

The price of MANA has been rather volatile early in the last year as the full project was deployed. It is a well-known currency, with a decent level of liquidity on the market, listed in multiple high-profile exchanges.

MKR

MKR is the utility and governance token used in the MakerDAO platform responsible for the emission of DAI. MKR is mainly used to repay the stability fee, and for governance purpose. MKR’s monetary policy is based on a deflationary economy.

MRK Smart contract Risk: B

MKR was launched in 2016, before DAI, with this contract deployed in September 2017. It is widely available on exchanges and increasingly popular in DeFi platforms accounting for nearly 700 thousand transactions.

MKR Counterparty Risk: C

The MKR token is part of the MakerDAO ecosystem and is decentralised and non-custodial. The token is used for governance votes based on the concept of anchor votes led by some whales. Some votes have even been taken over by whales with single addresses representing up to 94% of the voting power. On the Black Thursday crash of March 2020, the Maker system struggled to cope with price crashes and market congestion, leading to a multimillion deficit in the system. The Foundation, supported by governance funded the deficit by auctioning new MKR tokens. This auction has not lead to the reimbursement of vault holders who lost all their collateral, some are now attacking the foundation with a class action.

MKR Market Risk: C+

MKR is one of the most successful Ethereum projects, supported by a big community with a big market capitalisation. It is available on most exchanges, yet the volume is limited. Additionally, the token price has been quite volatile, and more so recently as MKR vulnerabilities were exposed.

REN

Ren Project connects blockchains and tokens through its trustless decentralised virtual machine that generates RenBTC. The REN protocol team has delivered this year launching renBTC well suited to become an industry standard. The blockchain bridge experience such as bridge.renproject.io and wbtc.cafe are seamless and we are considering it for a “BTC onramp” on our application.

Smart Contract Risk: B

Republic token is active and traded since December 2017 but has only recently launched with full functionalities. It has nearly two hundred thousand transactions.

Counterparty Risk: B

Ren holds decentralisation and privacy at its core offering one of the most permissionless and transparent tools to tokenise assets from another blockchains. It’s got a small community of 10,000 very active holders.

Market Risk: C+

REN has $150 million of market capitalisation and a decent amount of liquidity in big exchanges. Its recently witnessed some volatility with the launch of its core functionalities.

REP

Augur is a decentralised prediction market platform built on Ethereum; it is one of the first building blocks of DeFi.

REP Smart contract Risk: B

Augur is one of the oldest and most trusted projects in the space, starting in March 2014. The current contract deployed in July 2018 with only 300 thousand transactions.

REP Counterparty Risk: B

The project is completely decentralised with nearly 20,000 holders. It can continue to function even if the Augur team ceases to exist.

REP Market Risk: C+

It is traded on many exchanges and has a rather high volume. It is a popular token with a big market capitalisation and one of the first tokens to be included in DeFi protocols. The price of Augur has been rather volatile throughout the last year with a big spike in early 2020.

SNX

Synthetix is a decentralised synthetic asset platform that provides trackers of multiple currencies including USD, EUR, GBP, as well as cryptocurrencies like BTC, ETH and BNB which are backed by Synthetix Network Tokens SNX locked in the respective contract.

SNX Smart contract Risk: C+

SNX was first launched in March 2018 quickly building a community but has still to reach a significant number of transactions.

SNX Counterparty Risk: C

SNX is built on a decentralised infrastructure that has stayed robust while continuously innovating. Some security reports have highlighted undocumented functions in the Synthetix contracts that give some control to system maintainers and might present a security risk. If things go wrong it may be necessary to act fast and so these functions can be justified for the time being.

SNX Market Risk: B-

SNX price has shown strong growth in the last year. In parallel, the liquidity on exchanges has remained limited.

SNX holds the Synthetix ecosystem together as collateral with a collateralisation rate of 750%; it is transposed to Aave at the same level with a LTV of 15%.

UNI

UNI is the governance token of Uniswap Protocol, the DEX with the highest volume. It was distributed to users and liquidity providers gathering a diverse crowd of governors. The Uniswap DAO is now the DAO with the highest value under management.

The UNI token is audited and has been impressively battletested, nearly 1 million transactions, for such a short life. The smart contract uses some of COMP’s token code which has been tested by the markets.

UNI Counterparty Risk: B+

UNI is a permissionless token launched in some of the fairest ways witnessed. The Uniswap team, which has an impressive track record, will be giving up power over the protocol gradually over the next months.

UNI Market Risk: C+

The UNI token has been really well received by the community. The price quickly increased from nothing to 5$ then falling back down 50% leading to high volatility but also a large market capitalisation.

WBTC

Wrapped Bitcoin is an attempt to bring Bitcoin to the Ethereum blockchain, by tokenizing real bitcoin. The project responds to a real market demand since Bitcoin is the first and most successful cryptocurrency. The project was born in 2018 by the joint efforts of major players in the space: Kyber Network, the Ren Project and BitGo.

WBTC Smart contract Risk: B

WBTC has only been available since January 2019 having yet to gain significant traction with just over 200 thousand transactions and $100 million market capitalisation.

WBTC Counterparty Risk: C

WBTC is centralised with bitcoins custodially locked on the Bitcoin blockchain. The custody is performed by BitGo, a leader in blockchain custodian technologies.

WBTC Market Risk: B

WBTC is not easily available, accessible on some DeFi platforms with a low volume. Redemption of WBTC for the underlying asset requires KYC and a merchant license by the WBTC consortium, and the liquidity on the market is relatively low. WBTC has suffered market manipulation on Kyber exchange leading to a 60% drop in price. Still WBTC tracks the price of BTC which is not too volatile compared to other currencies considered.

Since WBTC is backed by the first and most successful digital currency BTC we consider some of these risks mitigated by BTC’s wider market which we use as market feed for the protocol’s oracle.

YFI

Yearn is an ecosystem of financial products governed by the YFI token. The smart platform offers different optimised strategies based on DeFi primitives such as Aave, gaining immense traction and attracting nearly a billion dollars of AUM in just over a month.

The governance token YFI is distributed to users who provide liquidity for the various products. The token holders discuss strategies and vote on policies in the governance forum while the technical side is led by Andrey Cronje.

The YFI smart contract was deployed on the 17th of July yet it already holds more transactions and holders than some other assets of portfolio. The simple ERC20 implementation with permissions only to the governance contract controlled by the YFI holders leads to a reduced technical risk

YFI Counterparty Risk: B

YFI is fully decentralised, its distribution to Yearn liquidity providers is among the fairest and most transparent. The community is already strong of 6,000 holders.

YFI Market Risk: C+

It is incredible to see the market metrics reached by YFI in just over a month. The weekly average 24h volume reaches nearly $100m. This has been accompanied by some of the most extreme price volatility observed even within the industry with the price surging from 50$ to 15,000$ leading to a high volatility risk.

ZRX

0x allows fast and efficient currencies exchanges on Ethereum, in a secure and non-custodial manner through a system of relayers. The token, ZRX, is mostly used for governance and as a utility token throughout the platform.

ZRX Smart contract Risk: B+

0x is one of the oldest projects on Ethereum, helping exchange ERC tokens since October 2016. The latest contract deployed in August 2017 now holds over a million transactions.

ZRX Counterparty Risk: B+

The project is completely decentralised and can continue to function even if the 0x team ceases to exist. It has a strong community with over 100,000 holders.

ZRX Market Risk: B-

It is traded on many exchanges and has a decent volume and rather low volatility.

Secondary Market

SETH

Synthetix is a decentralised synthetic asset platform on Ethereum that provides onchain exposure to real world assets. sETH is the ETH pegged synthetic asset backed by the network token.

sETH Smart contract Risk: D+

sETH was launched in September 2019 and has only a small number of transactions.

sETH Counterparty Risk: C-

Despite being built on a decentralised infrastructure, some security reports have highlighted undocumented functions in the Synthetix contracts that might present a security risk. These functions could allegedly give permission to the project maintainers to manipulate or withdraw the liquidity available within the Synthetix contracts, as well as manipulate user data (balances, debts).

sETH Market Risk: D

Right now, there isn’t much any liquidity available for sETH on centralised markets. Most of its use comes from the Synthetix exchange, with pretty limited DeFi usage. The market capitalisation also remains small. As a derivative of ETH, sETH holds the same volatility, being rather volatile in the last year.

Risk Monitoring

Mid July to end of August 2020 has sustained extreme growth for Aave both in terms of the balance of assets within the protocol as well as the price of those assets.

Small reduction in smart contract risk and counterparty risk due to an increase increased adoption of the assets in Aave’s Primary market leading to more tested smart contract and a more decentralised governance.

Overall decrease in market risk driven by increased market cap and volume but accompanied by increased volatility risk.

Asset Risk Map as of 15/07/2020

Between April and July the cryptocurrency market has experienced growth. The assets in Aave's portfolio have seen their market capitalisation explode as well as their usage. The parallel effect is an increase in volatility which is a crucial risk factor for the protocol.
