What are the algorithmic stablecoins? Learn more about the innovations and challenges of decentralized stablecoins

1. What is algorithmic stablecoin? White Speech Full Explanation

Algorithmic stablecoin is a form that does not rely on fiat currency or crypto assets as collateral, but throughSmart Contracting and Automation AlgorithmsTo keep the price stable cryptocurrency. The core operating logic of this type of stablecoin is: When the price deviates from the $1 anchor value, the systemAutomatic increase and decrease in the supply of tokensAdjusting market demand so that prices return to the target range.

Unlike USDT and USDC, “centralized mortgage-based stablecoins” such as USDT and USDC, algorithmic stablecoins do not require dollar reserves of equivalent value in banks, nor do they require excess collateralized crypto assets. What they're afterMore capital efficiency, more decentralized stability mechanism, is considered to be the most technically difficult and most innovative area in the stablecoin circuit.

Second, 5 major types and representative projects of algorithmic stablecoins

1. Rebase mechanism stablecoin

This kind of stablecoinRegularly adjust wallet balances for all holders, affects the market price through an increase in the number of tokens.

Representative Project:

• Ampleforth（AMPL）: The first algorithmic stablecoin to implement the Rebase mechanism. Automatically adjust the supply every 24 hours — all wallet balances increase when the price is above $1; the ratio decreases when the price is less than $1. The “share” held by the user does not change, but the “quantity” does.

2. Coin Tax Share Mechanism

introducingDual token or three token system, through the incentivized design of stock tokens and bond tokens, guides depositors to actively regulate the supply of stablecoins.

Representative Project:

• Base Cash（BAC）: Inspired by the Basis white paper, using BAC (stablecoin), BAS (stock token), BAB (bond token) tri-currency model. When the BAC is below $1, the system encourages users to purchase BAB Bonds at a discount price, which can be redeemed for more BAC in the future.
• Empty Set Dollar（ESD）: Simplified coin tax mechanism, regulating supply through the “Coupon” system, users can purchase coupons at a discount when the currency price is less than $1 and can be redeemed after future currency price rises.
• Dynamic Set Dollar（DSD）: ESD fork items that optimize adjustments for parameters such as inflation rate, unlock period, etc.

3. Partial mortgage algorithm stablecoin

Combining Collateral and Algorithmic MechanismsThe hybrid model is currently recognized as the most practical and risk-controlled development direction.

Representative Project:

• Frax Finance（FRAX）: One of the most successful algorithmic stablecoins of the moment. The first “fractional algorithm” mechanism, the mortgage rate can be adjusted to market demandDynamic Adjustment— When the market is confident, the mortgage rate decreases and the algorithm composition increases; vice versa, the mortgage rate increases. The stock token FXS is used to absorb the risk of system volatility.
• Neutrino USD（USDN）: Based on the Waves blockchain, combined with an algorithmic adjustment mechanism with WAVES tokens as partial collateral.

4th. Excess Collateral+Algorithm Optimization

It is essentially an overcollateralized stablecoin, butImplement a large number of algorithm elements to optimize clearing efficiency, interest rate pricing, and risk management。

Representative Project:

• DAI（MakerDAO）: Although it is based on over-collateralization of assets such as ETH, the Maker protocol introduced algorithmic mechanisms such as dynamic stable rates, automated clearing, reserve pools, and was seen as an early adopter of the “collateral+algorithm”.
• Liquity（LUSD）: With ETH only as a single collateral, a fully algorithmic clearing mechanism and a “stable pool” design enables efficient, low-cost stablecoin issuance.

5. New generation algorithmic stablecoins

Take the lessons of the Terra crash in 2022 and adoptMore sophisticated hedging strategies and risk buffering。

Representative Project:

• Terra USD (UST, Cracked): Once the market's first algorithmic stablecoin, it maintains a $1 anchor through a two-way exchange mechanism with LUNA tokens. May 2022 triggered a death spiral due to massive redemptions, falling to zero in one week, becoming the biggest stablecoin failure case in cryptocurrency history.
• USDD (Wavefield): Issued by TRON, the mechanism is similar to UST, but announces the creation of an excess collateralized reserve fund as a safety buffer.
• Ethena（USDE）: The next generation of algorithmic stablecoins represents a “delta neutral hedging strategy” — hedging ETH at the same time as staking ETH on the derivatives market, hedging the risk of price volatility and generating a stable income support mechanism through capital rates.

3. How does the algorithm stablecoin work? 3 major core mechanisms

1. Supply Adjustment Mechanism

• Price more than $1: Agreement to increase tokens, increase market circulation and cause price decline
• Price less than $1: Agreements to repurchase or destroy tokens, reducing circulation and driving up prices

2. Incentive and Benefit System

• When the stablecoin price is below $1, the system offers the opportunity to “buy bonds/coupons at a discount”
• Beneficiaries buy at low prices and then convert them into equivalent stablecoins to profit after price rises
• This set of gambling mechanismsNo need for protocol enforcement interventionInstead, the adjustment is automatically completed through the profit-taking behavior of market participants

3. Market Gambling Expectations

High Reliance on Algorithmic Stabilizer Coins for SuccessMarket participants' expectations of future prices。 When most people believe the mechanism works, arbitrage can stabilize prices; but when confidence collapses, everyone rushes to sell, it sets off a death spiral.

Fourth, the 4 main advantages of algorithmic stablecoins

✅ True Decentralization

Do not rely on centralized institutions to hold bank deposits or audit reports,Low risk of single point failure, Strong anti-censorship ability.

✅ Extremely high capital efficiency

No excess collateral required, in theory$1 of liquidity creates a $1 stablecoin, the efficiency of the use of funds is much higher than that of mortgage-backed stablecoins.

✅ DeFi native combinability

As native algorithmic assets on the chain, agreements with decentralized lending, derivatives, liquidity mining, and moreSeamless Integration, no need to trust centralized bridges.

✅ Monetary Policy Lab

Algorithmic stablecoins areDecentralized Central BankA trial vector that explores the cutting edge of automated interest rate regulation, supply management, and more for the crypto economy.

5. Top 5 Risks and Challenges of Algorithmic Stabilization Coins

⚠️ Death spiral

Deadliest risk。 When the price of the currency is below $1 and the market loses confidence, the holders panic sell-off → the currency falls further → the evaders do not dare to enter → the system mechanism fails → the price is permanently disconnected.Terra UST Crash Is the Worst Lesson, destroyed $400 billion in market capitalization in one week.

⚠️ Cold Startup Difficulty

Newly issued algorithmic stablecoinsLack of liquidity and market confidenceEven if the mechanism is well designed, it is difficult to attract enough beneficiaries and users in the beginning, and it is easy to fail before reaching scale effects.

⚠️ High market dependence

Algorithm Stabilizes CoinsExcellent performance in multiple marketsBUT IN EXTREME BEAR MARKETS OR LIQUIDITY DEPLETION, THE RISK TOLERANCE OF THE BENEFICIARIES DECREASES, AND THE STABILIZATION MECHANISM IS EASILY LOST.

⚠️ The mechanism is too complicated

The operating logic of most algorithmic stablecoinsExceeded threshold for general users, it is not easy to understand how to participate in escrow and how to assess risk, limiting the speed of adoption.

⚠️ Regulatory uncertainty

Financial regulators in various countries have become strict about “unsecured” algorithmic stablecoins. The U.S. SEC has recognized some algorithmic stablecoins as unregistered securities, which may be in the futureStronger regulatory pressure and even bans。

6. Future trend of algorithmic stablecoins (from 2026)

Despite the multiple major failures of algorithmic stablecoins, the field has not stopped innovating. In 2026, the market is moving in the following directions:

🔮 1. Mixed-mode becoming mainstream

Frax ModeBecome a new project benchmark — do not pursue a 100% algorithm, but keep part of the collateral as a safety cushion, and the mortgage rate can be adjusted dynamically. This is the best compromise between the ideal of decentralization and system stability.

🔮 2. Comprehensive Risk Management Enhancement

• AdditionReserve Buffer, for price intervention in extreme situations
• ImportingCircuit Breaker, prevents large amounts from being redeemed in a short time
• employsMultiple Collateral, disperse the risk of a collapse in the price of a single asset

🔮 3. Physical asset links

A new generation of projects will begin to be exploredU.S. Debt, Money Market FundsTokenization of real income assets, such as fixed income, increases vulnerability resistance as a source of income support for stablecoins.

🔮 4. Cross-chain liquidity integration

Deploy algorithmic stablecoins to multiple chains through cross-chain protocols, expand usage scenarios and liquidity depth and reduce single-chain ecosystem risks.

7. How do Taiwanese investors evaluate algorithmic stablecoins?

For Taiwanese investors, extreme caution should be exercised in the face of algorithmic stablecoins:

📌 3 Questions to Ask Before Investing

1. Does the project have no tangible collateral? — Pure algorithmic stablecoin risk is extremely high and is not recommended as a primary configuration
2. Have you been through extreme market testing? — At least one full bull cycle test
3. Are there sufficient liquidity and adoption rates? — Items with too low trading volume and lock-in volume, the risk of a death spiral is high

📌 The only recommended focus mark

As of 2026, algorithmic stablecoins that have been tested in the market and the mechanism continues to function only:

• Frax（FRAX）: Hybrid algorithm faucet, mortgage rate dynamic adjustment mechanism is mature
• Liquity（LUSD）: Overcollateral+Algorithmic Clearing, Extremely High Stability

Most of the other early algorithmic stablecoins (AMPL, ESD, BAC, USDN) are effectively in a “zombie state” or liquidity drain and are not recommended to invest new funds.

8. Conclusion: The value and lessons of algorithmic stablecoins

Algorithmic stablecoins are the domain of cryptocurrenciesThe most ambitious and dangerous financial experimentOne. They have proven that decentralized monetary policy is technically feasible, but it also comes at a devastating cost in the market capitalization of billions of dollars.

Key Lessons:

• Stable is not free, completely unsecured stablecoins are difficult to combat human panic
• Decentralization does not equate to zero risk, flaws in mechanism design are amplified by the market
• Scale does not equate to safety, Terra was once the world's first, as if it were zero at night

For ordinary investors,Algorithmic stablecoins are not suitable as a primarily held stable asset。 Truly safe stablecoins currently rely on compliant collateralised stablecoins such as USDT, USDC, or purchased and held on legitimate exchanges such as ZONE Wallet in Taiwan to ensure asset security through compliant fiat trust and cold wallet separation technology.

The story of algorithmic stablecoin is far from over, but it has returned from “the dream of subverting the dollar” to “a tool to strengthen the DeFi ecosystem” — a positioning shift that may be the beginning of the technology's true maturity.
