Stablecoins serve as a bridge between the world of cryptocurrencies and traditional fiat currencies. They are designed to maintain a stable value by being pegged to reserve assets such as the US dollar or gold. Among the many stablecoins available today, Tether (USDT) is the most widely recognized. Other popular options include USDC, BUSD, DAI, and USDP. Unlike volatile assets like Bitcoin, stablecoins minimize price fluctuations, making them suitable for everyday transactions, remittances, and trading on exchanges. Billions of dollars have flowed into stablecoins, underscoring their growing importance. In this article, we explore some of the most prominent stablecoins available today.
What Are Stablecoins?
Stablecoins are a category of digital currencies engineered to maintain a consistent value relative to a specific asset or basket of assets. They achieve this stability through various mechanisms, including collateralization with fiat currency, cryptocurrencies, or algorithmic methods. Below, we outline some of the leading stablecoins in the current market.
Tether (USDT)
Tether, commonly referred to as USDT, is a US dollar-pegged stablecoin launched in 2014 by iFinex Inc., a company registered in Hong Kong. As one of the largest cryptocurrencies by market capitalization, USDT aims to maintain a 1:1 value with the US dollar. When users deposit fiat currency into Tether’s reserves, an equivalent amount of USDT is issued.
USD Coin (USDC)
USD Coin (USDC) is a digital currency fully backed by US dollar assets. Managed by Centre, a consortium founded by Coinbase and Circle, USDC is the second-largest dollar-backed stablecoin. Each USDC token corresponds to one US dollar held in reserve. When users purchase USDC, new tokens are minted; when they redeem them, the tokens are destroyed, and fiat currency is returned to the user’s bank account.
Binance USD (BUSD)
Binance USD (BUSD) is a regulated stablecoin issued in partnership between Binance and Paxos. It is pegged 1:1 to the US dollar and holds the distinction of being the first stablecoin approved by the New York State Department of Financial Services (NYDFS). Paxos holds the collateral in US bank accounts, and regular audits ensure that the reserves fully back the circulating supply of BUSD.
Dai (DAI)
Dai is a decentralized stablecoin pegged to the US dollar but backed by cryptocurrency collateral rather than fiat reserves. The MakerDAO community governs Dai’s stability mechanisms. Users generate Dai by locking cryptocurrency assets, primarily Ethereum, into the Maker Protocol. To reclaim their collateral, users must return the borrowed Dai along with a stability fee. This over-collateralization model helps maintain Dai’s peg even during market volatility.
Paxos Standard (USDP)
Paxos Standard (USDP) is a regulated stablecoin issued by Paxos Trust Company, which operates under the oversight of the NYDFS. Paxos specializes in digitizing asset movement, exchange, and settlement. USDP is fully backed by US dollar reserves and offers a transparent and compliant stablecoin solution.
TrueUSD (TUSD)
TrueUSD (TUSD) is a stablecoin pegged 1:1 to the US dollar. It operates as a redeemable token, meaning holders can exchange it for US dollars at any time. Unlike some other stablecoins, TUSD uses multiple third-party escrow accounts to hold its dollar reserves, ensuring that no single entity controls the collateral.
Gemini Dollar (GUSD)
The Gemini Dollar (GUSD) is a regulated stablecoin issued by Gemini Trust Company. Each GUSD token is backed by one US dollar held in a FDIC-insured bank account. The reserves undergo monthly audits by independent accounting firms, and reports are publicly available. GUSD combines the stability of fiat with the efficiency of blockchain technology.
Reserve Rights (RSR)
Reserve aims to build a decentralized stablecoin and payment system capable of self-regulating its supply based on demand. It is designed to be fully collateralized and serves as a reliable store of value, particularly in regions with unstable financial systems or high inflation. The Reserve ecosystem includes a dual-token structure for stability and governance.
STASIS EURS (EURS)
STASIS EURS is a euro-pegged stablecoin built on the Ethereum blockchain. It caters primarily to European institutional investors seeking exposure to digital assets without volatility. STASIS combines the potential of cryptocurrencies with the stability of the euro, offering tokenization services, third-party audits, and regulatory compliance.
USDK
USDK is a blockchain-based stablecoin operating on the Ethereum network. It is issued and redeemed at a 1:1 ratio with the US dollar and is backed by assets held by PrimeTrust, a regulated custodian. This ensures full collateralization and transparency for users.
Risks Associated with Stablecoins
While stablecoins are designed to maintain a fixed peg to a fiat currency, this stability is not guaranteed. For example, Terra’s algorithmic stablecoin, UST, lost its dollar peg in May 2022 and plummeted in value. Although stablecoins aim to reduce volatility, events like these highlight the risks of de-pegging, especially for algorithmic or under-collateralized models.
Stablecoins play a critical role in the crypto space by providing stability and enabling seamless transactions. However, users should remain aware of the underlying mechanisms and risks associated with each stablecoin.

What are the main types of stablecoins?
Stablecoins can be categorized into fiat-collateralized (e.g., USDT, USDC), crypto-collateralized (e.g., DAI), and algorithmic (e.g., former UST). Each type has distinct advantages and risks.
Why do some stablecoins lose their peg?
A stablecoin can lose its peg due to insufficient collateral, loss of market confidence, or flaws in its design. Algorithmic stablecoins are particularly vulnerable to bank runs or market crashes.
