A COMPREHENSIVE THREAD ✍🏻 on Stablecoins
We dig into the design principles and understand the different types of #stablecoins
Also, make sense of what @BeanstalkFarms is trying to achieve
Let's dive right into it
🧵
👇
🧵/3
Economy ➡️ Decentralized
When
Crypto ➡️ Mass Adopted
And
Mass Adoption ➡️ Crypto as a Medium of exchange/ Global transfer of value
🧵/4
#Cryptocurrencies
‣ The wild west of the financial world
‣ Highly speculative
‣ Volatile, restricting the use for payments & trade (medium of exchange)
📈 $BTC price today (< $16500) - almost 1/4th of the price last October (>$61,000)
🧵/5
Importance of Stablecoins
‣ Provide price stability & steady valuation
‣ Eliminate volatility (no massive fluctuations)
‣ Pegged to the value of another stable asset/ #FIAT (US dollar)
‣ Make #crypto a medium of exchange
🧵/6
#Stablecoin Trilemma
Design principle around which Stablecoins exist
‣ Price Stability
‣ Capital Efficiency
‣ #Decentralization
🧵/7
Stability
Ability to remain at its peg (sans large variances) irrespective of market conditions
1 unit of #STABLECOIN = 1 unit of PEGGED ASSET (under all conditions)
Affected by market expectations & trust
🧵/8
Efficiency
Capital required to secure the stablecoin
Locking up more than $1 of #collateral to create $1 of #stablecoin is deemed inefficient
Efficiency = Low minting cost
Can lead to stablecoin supply constraints due to higher capital requirement
🧵/9
#Decentralization
The extent of dependence on centralized systems/entities
Mitigates risks of single-point failure
Makes the system #trustless
🧵/10
Achieving Stablecoin Trilemma = End State
No #stablecoin has been able to embody all three characteristics
Price stability (the most important design principle)
Achieving it = Trade-off in either #decentralization or capital efficiency
🧵/12
Fiat-backed coins (1:1 collateralization)
Account for over 90% of the entire stablecoin supply
Backed by a #FIAT currency
A custodian/centralized organization/central issuer holds the fiat collateral/currency in proportion to the no of coins in circulation #CENTRALIZED
🧵/13
Simplest stablecoin category due to the structural advantage
Most popular ones are backed by #USD 💵💵
Includes $USDT (#Tether), $USDC (#Circle), $BUSD (#Paxos)
🧵/14
Commodity-backed coins
Collateralized with commodities like precious metals/oil/real estate instead of #FIAT (mostly #Gold)
Rarely used in #DeFi
Includes #Tether Gold and #Paxos Gold
🧵/15
🚩 Problems - FIAT/Commodity backed
#Decentralization traded for capital efficiency/price stability
Govt regulations & Intervention- Threat to #censorship
Lack of Transparency & Accountability- Systemic risk for the industry
Needs Trust on the part of users/investors
🧵/16
Examples 🔺
Censorship 😷
#Circle ($USDC) blacklisted wallets that interacted with #Tornado Cash after the #SEC added Tornado Cash smart contract addresses to the #OFAC list
🧵/17
No option but Trust 🫱🏿🫲🏻
With endless rumors about $USDT being partly backed/backed by volatile/riskier assets than cash/equivalents, there have been no efforts from #Tether to prove otherwise
No audit reports/attestations
No choice for users/investors but to trust
🧵/18
Systemic Risk 💣 (a ticking time bomb)
Imagine the kind of chaos that will ensue over the entire industry if #Tether fails
🧵/19
Recommendations 🕵️
Transparency through regular #audits & attestations 🔍
Accountability for such actions to become an industry norm (how #CEXs have started the proof of reserves 📖)
Need these #Centralized systems to be forthright
🧵/20
Crypto-backed coins (overcollateralized)
• Similar to fiat-backed coins
• Underlying collateral is another #cryptocurrency instead of #FIAT
• No central entity/custodian (#Decentralized)
• Coins issued on-chain employing smart contracts (#Trustless)
🧵/21
• A coin of higher value is locked in to issue a lesser-valued stablecoin
• Over-collateralization serves as a buffer against the #collateral coin’s volatility
• Popular example - $DAI (#Maker protocol)
#DAI requires a collateral ratio of 150% for borrowing
🧵/22
🚩 Problems
‣ Capital Inefficiency
‣ Reliance on centralized stablecoins as collateral ($USDT & $USDC)
🧵/23
Capital Inefficiency
• Capital efficiency is traded for #decentralization to achieve price stability
• To reduce the required #collateralization ratio, some stablecoin protocols accept other stablecoins with deep liquidity ($USDC) as on-chain collateral
🧵/24
Reliance on #centralized stablecoins as #Collateral (this one is pretty baffling)
• #Decentralized stablecoins are needed to mitigate the risks of Centralized stables
• However, decentralized protocols mostly use centralized stablecoins as collateral
🧵/25
• Using centralized stablecoins exposes them to the same risks they are trying to mitigate
Even though decentralized protocols are working on ways to increase the capital efficiency to mint/borrow stablecoins, we are still a long way from home
🧵/26
#Algorithmic coins (Undercollateralized)
‣ Promising solution to solve the #stablecoin trilemma
‣ Achieve capital efficiency
‣ Do not rely on traditional off-chain/on-chain collateral
‣ Maintain price stability using specialized #algorithms & smart contracts
🧵/27
‣ Algo designed to #burn/remove, or mint/create coins to modulate the supply and maintain equilibrium and price stability
‣ Usually a two-token model with a #mint-&-burn mechanism for a second price-floating token
‣ Stablecoin is secured by the value of a second token
🧵/28
‣ Protocol ensures that investors can always swap one stablecoin for $1 of the price-floating token
‣ Arbitrageurs are incentivized to buy/sell the stablecoin on the market and exchange it for the price-floating token if it's trading below/above the peg
🧵/29
🚩 Problems
• Value created out of thin air
• Can only survive as long as there is trust in its #algorithm
• If the value of the corresponding risk-absorbing token isn't strong enough to manage the demand and supply, it won't survive
🧵/30
• In an attack of short duration, the algo will balance #supply/ #demand and bring the stablecoin back to its peg
• But a well-capitalized attack by highly solvent market players on the pegging mechanism in times of market uncertainty can lead to disastrous consequences
🧵/31
Example 🔺
Proven by the events around the $UST collapse
An attack coordinated in times of big market uncertainty
Investors lost their trust in UST
Resulted in a so-called death spiral
🧵/32
To support the #UST price, more and more Luna tokens had to be minted, heavily inflating the #Luna price
As the UST price fell below the #peg, there was a huge loss of trust
It led to more and more people exiting the coin
The rest is a story
🧵/33
To SUM UP
❌CENTRALIZATION - FIAT-backed coins
❌OVER-COLLATERALIZATION - Crypto/Commodity-backed coins
❌INSTABILITY - Undercollateralized #Algorithmic coins
🧵/34
Challenges/ Opportunities
Existing stablecoins can’t scale to meet the growing demand owing to the COLLATERAL REQUIREMENT
Increased demand for stablecoins means an enormous amount of #collateral
Insufficient collateral, both on-chain & off-chain, to meet this demand
🧵/35
Stablecoins are critical for the mass adoption of #DeFi & #Web3
The design space is highly innovative
Many interesting approaches are being worked on (such as delta-neutral #derivative positions)
While many designs have failed, some parts have been successfully adopted
🧵/36
Research and development are critical to bringing improvements to the existing designs, or
Perhaps a need for a new design altogether
@BeanstalkFarms is one such experiment
🧵/37
$BEAN is a credit-based stablecoin
‣ Relies on #credit as opposed to #collateral
‣ An experiment testing the scalability of an on-chain stablecoin protocol
‣ Based on an algorithm, $BEAN's design differs from other algorithmic stablecoins such as $UST
🧵/38
‣ Doesn't use a two-token model or rely on a tradeable governance token (used for speculation and as a risk absorber)
‣ Aligns value creation and utility within the protocol
‣ Risks are held by the creditors of the system (Transparency in the docs)
🧵/39
#Beanstalk's story is one of success, a downfall through a brutal exploit, and then recovering & rising!
On 6 Aug'22, Beanstalk relaunched the protocol after going offline for 4 months and 1 year after its initial deployment
It has since completed 2 #security audits
🧵/40
The protocol continues to push in its quest to solve the existing stablecoin problems
Stay tuned for what shall follow, and let's see how their unique approach fares in the future
