Stablecoins have become a cornerstone of the cryptocurrency ecosystem, offering users a reliable way to store value with minimal volatility. Unlike traditional cryptocurrencies such as Bitcoin or Ethereum, which can experience dramatic price swings, stablecoins are designed to maintain a consistent value—typically pegged 1:1 to a fiat currency like the U.S. dollar. This makes them ideal for trading, payments, remittances, and participation in decentralized finance (DeFi) applications.
In this comprehensive comparison, we’ll examine four of the most widely used dollar-pegged stablecoins: USDT, TUSD, FDUSD, and BUSD. We’ll explore their origins, backing mechanisms, transparency levels, market capitalizations, and real-world use cases. By the end, you’ll have a clearer understanding of how these digital assets differ and which might best suit your financial needs.
What Is USDT?
Tether (USDT) is the oldest and most dominant stablecoin in the crypto market. Launched in 2014 by Tether Limited (originally under the name Realcoin), it was among the first tokens to offer a stable digital alternative pegged to the U.S. dollar. Today, USDT maintains a market capitalization exceeding $118 billion, with daily trading volumes often surpassing $35 billion across global exchanges.
While initially claimed to be fully backed by cash reserves, Tether has since disclosed that its reserves include a mix of cash, cash equivalents, short-term deposits, and commercial paper. This diversified reserve structure has sparked debate around transparency, though regular attestation reports aim to provide some level of accountability.
Despite scrutiny in earlier years, USDT remains the most widely adopted stablecoin due to its deep liquidity and broad integration across exchanges, wallets, and DeFi protocols.

What Is TUSD?
TrueUSD (TUSD) was launched in 2018 by TrustToken—now rebranded as Archblock—and stands out for its strong emphasis on transparency and regulatory compliance. Each TUSD token is fully backed by U.S. dollars held in segregated escrow accounts managed by trusted financial institutions.
One of TUSD’s defining features is its commitment to third-party audits. Independent accounting firms conduct regular verifications of its reserves, and results are publicly available. This transparency helps build trust among institutional investors and privacy-conscious users alike.
With a market cap of approximately $495 million, TUSD is significantly smaller than USDT but continues to gain traction among users prioritizing auditability and legal clarity. It operates primarily on Ethereum and other major blockchains, supporting use cases in lending platforms and cross-border transactions.
What Is FDUSD?
First Digital USD (FDUSD) is one of the newer entrants in the stablecoin space, introduced in 2023 by Hong Kong-based First Digital Trust. Designed with institutional adoption in mind, FDUSD is fully backed by U.S. dollar-denominated liquid reserves and undergoes regular attestations to verify solvency.
What sets FDUSD apart is its programmability and focus on emerging markets. The token functions not just as a medium of exchange but also as a tool for programmable finance—supporting escrow services, insurance contracts, and automated settlements.
Though FDUSD has a relatively modest market cap of around $450 million, its strategic positioning in Asia and strong institutional backing make it a noteworthy player in the evolving stablecoin landscape.

What Is BUSD?
Binance USD (BUSD) was launched in 2019 as a collaboration between Binance, the world’s largest cryptocurrency exchange, and Paxos Trust Company—a regulated financial institution based in the U.S. BUSD is fully backed by U.S. dollar reserves held in FDIC-insured banks and undergoes monthly audits conducted by independent firms.
BUSD operates on multiple blockchains, including Ethereum and BNB Smart Chain (formerly Binance Smart Chain), ensuring fast and low-cost transactions. It became widely used across DeFi platforms, payment gateways, and savings products within the Binance ecosystem.
As of now, BUSD has a market capitalization of over $694 million and remains popular despite regulatory pressure that led to its delisting from some major U.S.-based exchanges. Its strong compliance framework continues to appeal to users seeking a regulated digital dollar solution.
