Overview

Tether Limited is a privately held financial-technology and digital-asset company whose principal business is issuing Tether tokens, especially USDT, a cryptocurrency designed to track the value of the United States dollar. The company originated in 2014 as Realcoin, a project associated with Brock Pierce, Reeve Collins, and Craig Sellars. It initially used the Omni Layer on the Bitcoin blockchain to create a token intended to combine the transferability of cryptocurrency with the relative price stability of a fiat currency. The business adopted the Tether name later in 2014. USDT became one of the most important settlement and liquidity instruments in cryptocurrency markets. Traders and exchanges use it as a dollar substitute for moving value between digital assets, venues, and users without relying on conventional banking transfers. It has subsequently been issued on multiple blockchain networks, including Ethereum and Tron, and has developed substantial use in international transfers and payments. Tether has also issued tokens linked to other assets, including EURT, associated with the euro; CNHT, associated with offshore Chinese yuan; MXNT, associated with the Mexican peso; and XAUT, commonly called Tether Gold, which is linked to physical gold. The company’s growth has been closely connected with Bitfinex and their common corporate ecosystem. Tether’s ultimate ownership and management have historically overlapped with iFinex, the parent group associated with the Bitfinex cryptocurrency exchange. This relationship has helped Tether obtain distribution and liquidity but has also generated questions about corporate separation, reserve management, and governance. Tether has remained privately held and does not publish the same level of financial information as a listed company. Reserve transparency has been a recurring issue. Tether historically described USDT as fully backed by equivalent dollar reserves, but later disclosures showed that the backing included a broader range of assets rather than only cash. The company now publishes periodic reserve attestations rather than conventional full-scope audits. Its reported holdings have included United States Treasury securities, cash, secured loans, precious metals, bitcoin, and other assets. Rising interest rates and the scale of its Treasury holdings have made reserve income an important part of the company’s economics, although detailed financial figures should be interpreted in the context of Tether’s own attestations. Tether expanded beyond stablecoin issuance during the 2020s through investments in bitcoin mining, energy, payments, data infrastructure, communications, and digital-media businesses. It invested in payment processor CityPay.io, supported mining initiatives including renewable-energy projects, disclosed financing and equity relationships involving Northern Data and Bitdeer, and announced a major investment in Rumble. These activities reflect a strategy of using stablecoin-related earnings to build a broader digital-asset and infrastructure portfolio. In 2023, Paolo Ardoino became chief executive officer after previously serving as chief technology officer. Under his leadership, Tether emphasized expansion, bitcoin and infrastructure investment, and closer alignment with El Salvador. In 2025 the company announced a formal corporate base in El Salvador and continued exploring a United States-oriented stablecoin initiative. Tether remains one of the most prominent issuers in the global stablecoin sector, while its long-term position continues to depend on reserve credibility, regulatory treatment, network distribution, and the role of stablecoins in cryptocurrency and payments markets.

History

Tether began in 2014 as Realcoin, a project associated with Brock Pierce, Reeve Collins, and Craig Sellars. Its initial concept was to issue blockchain-based tokens representing stable units of fiat currency. The first implementation used the Omni Layer connected to Bitcoin, allowing users to transfer tokens while targeting a one-to-one relationship with the United States dollar. The project changed its name to Tether later in 2014 and formed relationships with cryptocurrency businesses, including Bitfinex. USDT and related tokens gained traction as cryptocurrency exchanges needed a liquid dollar substitute that could move on blockchain networks. Unlike conventional bank dollars, USDT could be transferred continuously between exchanges and wallets. It was later issued on additional networks, notably Ethereum and Tron, which broadened its accessibility and transaction capacity. Euro-linked and offshore yuan-linked products were also introduced, although none achieved the scale of USDT. Tether’s relationship with Bitfinex became central to its development and controversial reputation. Both businesses were associated with iFinex and shared important shareholders, executives, and infrastructure. In 2017 and 2018, the absence of a completed audit after Tether’s relationship with Friedman LLP ended prompted renewed questions about reserves. Those questions intensified after allegations that funds connected with Bitfinex had been transferred or supported through Tether during a period when Bitfinex faced an $850 million shortfall involving a payment processor. The New York Attorney General brought proceedings against iFinex in 2019. The matter was settled in 2021, with iFinex agreeing to pay an $18.5 million penalty and cease trading with New York customers, without admitting wrongdoing. In the same year, the CFTC fined Tether $41 million over statements concerning the extent to which USDT had been backed by fiat currency during earlier periods. These events contributed to a shift from simple claims of cash backing toward more detailed reserve disclosures and periodic attestations. Tether Gold, a token linked to physical gold, was launched in 2020. During the cryptocurrency expansion of 2020 and 2021, USDT became the dominant stablecoin by circulation and trading usage. The collapse of TerraUSD in 2022 further highlighted the distinction between algorithmic stablecoins and tokens claiming support from identifiable reserves. Tether subsequently reported stronger profitability as interest income from reserve assets increased. From 2023 onward, Tether pursued a broader investment strategy. It allocated capital to bitcoin mining and energy projects, including renewable-energy initiatives, and invested in payments companies such as CityPay.io. It also disclosed relationships with Northern Data and Bitdeer and expanded into communications, data storage, and digital media through affiliated investments. This marked a transition from a narrowly defined token issuer to a diversified digital-asset company. Paolo Ardoino, previously Tether’s chief technology officer, became CEO in late 2023. In 2025 the company announced a formal move toward El Salvador as its corporate base and reported additional executive changes, including Simon McWilliams becoming chief financial officer and Giancarlo Devasini becoming chairman. Tether also explored a United States-focused stablecoin product known as USAT. The company remains privately owned, globally active, and highly influential, but continues to face scrutiny regarding reserve quality, disclosure standards, regulatory compliance, and the governance implications of its relationship with Bitfinex and iFinex.

Products and positioning

A global stablecoin issuer and digital-asset infrastructure company centered on dollar-denominated liquidity.

Dollar-pegged stablecoin · 2014
USDT
USDT is Tether’s flagship token and is designed to track the United States dollar. It is used as a trading and settlement asset across cryptocurrency exchanges, wallets, payment services, and blockchain applications. The token began on the Omni Layer and later expanded to networks including Ethereum and Tron. Tether states that circulating USDT is supported by reserves, although the composition of those reserves and the verification standards applied to them have been subjects of regulatory and public scrutiny.
Euro-linked stablecoin · 2015
EURT
EURT is Tether’s euro-referenced token. It was introduced alongside the company’s early fiat-linked products to provide a blockchain-based unit denominated in euros. Its role and market scale have remained substantially smaller than those of USDT.
Offshore yuan-linked stablecoin · 2019
CNHT
CNHT is linked to offshore Chinese yuan. The token represents Tether’s attempt to extend its asset-pegged model beyond dollars and euros into another major currency. Public market adoption has been considerably less significant than USDT.
Gold-backed digital asset · 2020
Tether Gold (XAUT)
XAUT is designed to represent ownership of physical gold, with each token associated with one troy ounce of gold held in vaults in Switzerland. It gives digital-asset users exposure to a commodity reference rather than a fiat currency and forms part of Tether’s diversification beyond dollar-based stablecoins.
Mexican peso-linked stablecoin · 2022
MXNT
MXNT is a peso-referenced stablecoin introduced for users and businesses connected with the Mexican market. It extends Tether’s multi-currency product strategy, although its public profile and circulation are smaller than those of USDT.
