What Is an Algorithmic Stablecoin?

Algorithmic stablecoins, lacking real-world collateral, utilize a dynamic supply-demand mechanism to maintain a target price through minting or burning tokens, offering decentralization and inflation resistance but also posing risks of volatility and algorithmic failures.

What Is an Algorithmic Stablecoin?

1. Definition

An algorithmic stablecoin is a type of cryptocurrency whose value is pegged to a target currency, such as the US dollar, through an algorithmic mechanism that adjusts the supply and demand of the stablecoin. Unlike fiat-backed stablecoins, algorithmic stablecoins do not hold any real-world assets as collateral.

2. Mechanism

Algorithmic stablecoins maintain their peg through a combination of two processes:

• Expansionary: When the stablecoin price falls below the target, the algorithm mints new tokens, increasing the supply. This drives up the demand and price of the stablecoin.
• Contractionary: Conversely, when the stablecoin price rises above the target, the algorithm burns tokens, decreasing the supply and reducing the price.

3. Stability Mechanisms

Algorithmic stablecoins use various mechanisms to ensure price stability, including:

• Seigniorage: Profits from the expansionary and contractionary processes are used to incentivize holders and stabilize the price.
• Oracle: The algorithm relies on oracles to provide accurate data on the target currency's price.
• Feedback Loop: The expansionary and contractionary processes create a negative feedback loop that helps the stablecoin converge to the target price.

4. Examples of Algorithmic Stablecoins

Some notable algorithmic stablecoins include:

• TerraUSD (UST)
• Dai (DAI)
• Basis Cash (BAC)
• Fei Protocol (FEI)

5. Advantages

• Decentralization: Algorithmic stablecoins are not backed by a centralized entity, making them more resistant to censorship.
• Inflation Resistance: The contractionary mechanism can help mitigate inflation by reducing the supply of the stablecoin.
• Programmatic Transactions: Algorithmic stablecoins can facilitate programmable transactions, such as automatic payments or decentralized exchanges.

6. Risks

• Volatility: Algorithmic stablecoins can experience significant price fluctuations while maintaining their peg.
• Algorithmic Failures: The complex algorithms used in algorithmic stablecoins can introduce potential vulnerabilities.
• Dependence on Oracles: The accuracy of the stablecoin's price peg relies heavily on the accuracy of the oracles used.
