Stablecoins: what are they and how do they work?
Stablecoins have gained a lot of popularity in recent years as they offer a stable price to their users, unlike cryptocurrencies such as Bitcoin or Ethereum, whose prices can be highly volatile. Stablecoins are digital tokens that are designed to maintain a stable value by being pegged to a stable asset such as a fiat currency or a commodity. In this article, we will explore what stablecoins are, how they work, and their benefits and limitations.
What are Stablecoins?
Stablecoins are digital tokens that aim to maintain a stable price by being backed by a stable asset such as a fiat currency, a commodity, or even another cryptocurrency. They offer users a reliable and stable way to store and transfer value without being affected by the volatility of traditional cryptocurrencies.
Stablecoins can be categorized into three main types: centralized, decentralized, and algorithmic stablecoins. Centralized stablecoins are issued and managed by a central entity or authority, such as a bank or a company. Decentralized stablecoins, on the other hand, are issued and managed through a decentralized network of users without any central authority. Algorithmic stablecoins, as the name suggests, use algorithms and smart contracts to maintain their stability.

How do Stablecoins Work?
The way stablecoins work varies depending on their type. However, the common feature among all stablecoins is that they are backed by an asset that ensures their stability.
Centralized Stablecoins
Centralized stablecoins are backed by fiat currencies, such as the US dollar or the euro. The central entity that issues and manages the stablecoin holds the equivalent amount of fiat currency in reserve. The stablecoin can then be traded or used for payments with the assurance that it can be redeemed for the equivalent amount of fiat currency at any time.
One of the most popular centralized stablecoins is Tether (USDT), which is pegged to the US dollar. Tether Limited, the company behind USDT, claims that for every USDT token issued, it holds one US dollar in reserve.
Decentralized Stablecoins
Decentralized stablecoins are issued and managed through a decentralized network of users, without any central authority. These stablecoins use a mechanism called a decentralized autonomous organization (DAO) to maintain their stability.
In a DAO, users can buy and sell stablecoins and participate in the governance of the network. The stability of the stablecoin is maintained through a combination of market forces and the actions of the DAO. For example, if the price of the stablecoin goes above its pegged price, users can sell the stablecoin back to the DAO in exchange for the underlying asset, which reduces the supply of the stablecoin and brings its price back to its peg.

One example of a decentralized stablecoin is DAI, which is pegged to the US dollar. DAI is created through a system of smart contracts on the Ethereum blockchain, and its stability is maintained through the actions of the MakerDAO community, which governs the network.
Algorithmic Stablecoins
Algorithmic stablecoins use algorithms and smart contracts to maintain their stability. These stablecoins are not backed by any asset but instead use market mechanisms to maintain their peg.
In an algorithmic stablecoin system, the price of the stablecoin is maintained through a combination of supply and demand. If the price of the stablecoin goes above its peak, the smart contract automatically increases the supply of the stablecoin, which brings its price back down. If the price of the stablecoin goes below its peak, the smart contract reduces the supply of the stablecoin, which brings its price back up.
One example of an algorithmic stablecoin is Basis, which was designed to be pegged to the US dollar. However, Basis was shut down in 2018 due to regulatory concerns.
Benefits of Stablecoins
Stablecoins offer several benefits to their users, including:
Stability
The main benefit of stablecoins is their stability. Unlike traditional cryptocurrencies, stablecoins maintain a stable price, which makes them more reliable for transactions and as a store of value.
Low Transaction Costs
Stablecoins can be transferred with very low transaction costs, which makes them an attractive option for cross-border payments and remittances.
Privacy
Stablecoins offer a high degree of privacy, as transactions are recorded on a blockchain, which is a decentralized and immutable ledger. This makes it difficult for third parties to track and trace transactions.
Accessibility
Stablecoins are accessible to anyone with an internet connection, which makes them particularly useful for people who do not have access to traditional banking services.
Use in Decentralized Finance (DeFi)
Stablecoins are an integral part of the growing DeFi ecosystem, which allows users to access financial services without the need for traditional financial institutions. Stablecoins are used as collateral for loans, as a means of payment, and for trading in DeFi platforms.
Limitations of Stablecoins
Despite their benefits, stablecoins also have some limitations, including:
Centralization
Centralized stablecoins are issued and managed by a central entity, which makes them vulnerable to the same risks as traditional fiat currencies, such as inflation, government intervention, and counterparty risk.
Regulation
Stablecoins are a relatively new financial instrument, and their regulatory status is still uncertain in many jurisdictions. This can create legal and regulatory risks for users and issuers of stablecoins.
Market Risk
Stablecoins are still subject to market risk, as their stability depends on the underlying asset they are pegged to. If the value of the underlying asset drops significantly, the stability of the stablecoin can be compromised.
Smart Contract Risk
Algorithmic stablecoins rely on smart contracts to maintain their stability, which can be vulnerable to bugs and exploits. If a smart contract is compromised, it can lead to the loss of user funds and the destabilization of the stablecoin.
Conclusion
Stablecoins offer a stable and reliable way to store and transfer value in a decentralized and borderless manner. They have several benefits, including stability, low transaction costs, privacy, accessibility, and their use in DeFi. However, stablecoins also have limitations, including centralization, regulatory uncertainty, market risk, and smart contract risk.
As the adoption of cryptocurrencies and blockchain technology continues to grow, stablecoins are likely to play an increasingly important role in the financial system. However, their long-term viability and regulatory status will depend on their ability to address the limitations and risks associated with their use.
