Tether (USDT) is the world’s first and most widely used stablecoin, ranking as the third-largest cryptocurrency by market capitalization. As a fiat-collateralized digital asset primarily pegged to the U.S. dollar, USDT maintains a stable value of approximately $1. This consistency has made it a cornerstone of the crypto ecosystem—serving as a bridge between traditional finance and decentralized digital economies.
Originally launched in 2014 under the name Realcoin, Tether was founded by Reeve Collins, Craig Sellars, and Brock Pierce. The token is issued by Tether Limited, a company closely linked with the Bitfinex exchange, and is fully redeemable for USD on a 1:1 basis. While initially built on the Bitcoin blockchain via the Omni Layer protocol, USDT has since expanded across more than a dozen blockchain networks—including Ethereum, Tron, and Solana—making it one of the most interoperable assets in the crypto space.

Despite its Bitcoin origins, USDT sees the highest usage on Ethereum, where it operates as an ERC-20 token. This cross-platform flexibility allows users to transfer USDT quickly and affordably across ecosystems, enabling seamless trading, payments, and value storage in Web3 environments.
How Tether Maintains Its Peg
Tether's stability stems from its reserve-backed model. Whenever new USDT tokens are minted, Tether Limited allocates an equivalent amount of USD into its reserves—ensuring each token remains fully backed. These reserves consist of traditional currencies, cash equivalents, short-term deposits, commercial paper, U.S. Treasury bills, corporate bonds, secured loans, precious metals, and other diversified investments.
Unlike early claims that USDT was backed solely by cash deposits, Tether now discloses a broader reserve composition. The company publishes daily reserve reports and undergoes quarterly attestation by independent accounting firms to enhance transparency and trust.
This model allows Tether to scale supply dynamically based on market demand without diluting value. There is no fixed supply cap; Tether Limited can issue additional tokens as long as sufficient collateral supports them. Conversely, when users redeem USDT for fiat, the corresponding tokens are burned—reducing circulation proportionally.
With over 69 billion USDT in circulation, Tether plays a critical role in liquidity provision across centralized exchanges, decentralized finance (DeFi), and peer-to-peer markets.
Expansion Across Blockchains
Tether’s multi-chain strategy has been key to its dominance. By deploying USDT across high-performance and scalable networks, it ensures accessibility, speed, and cost-efficiency for users worldwide.
- In January 2021, Tether minted a record 2 billion USDT within a single week—driven by surging institutional interest and growing distrust in traditional financial systems.
- November 2021 marked the launch of USDT on Avalanche, a high-speed, low-fee smart contract platform. Initially supported by Bitfinex, this integration enabled faster and cheaper transactions for traders and DeFi participants.
- In April 2022, USDT expanded to Kusama, the so-called “Canary Network” for Polkadot. This move signaled deeper integration into the Polkadot ecosystem, with Polkadot itself expected to support USDT soon.
- May 2022 saw USDT go live on Polygon, Ethereum’s leading Layer-2 scaling solution. At the time of integration, Polygon hosted over 19,000 decentralized applications (DApps), with more than $5 billion in total value locked (TVL). As the 11th blockchain to support USDT, Polygon further solidified Tether’s status as the universal stablecoin.
These expansions reflect Tether’s strategic focus on scalability, interoperability, and user accessibility—core principles driving adoption in emerging markets and DeFi platforms.
Use Cases and Global Impact
USDT serves multiple functions across the digital economy:
- Trading Pair Dominance: Most major crypto exchanges list USDT as a primary trading pair due to its stability and wide acceptance.
- Web3 Transactions: Users leverage USDT in wallets and DApps for payments, staking, lending, and gaming.

Tether emerged from the Mastercoin Foundation—a pioneering project in early Bitcoin development. Its technological roots lie in the Omni Layer, a protocol built on Bitcoin that enables asset creation and transfer.
The founding team includes:
- Brock Pierce: A well-known entrepreneur and former chairman of the Bitcoin Foundation. He co-founded major blockchain ventures like Block.one, the company behind the EOS blockchain.
- Reeve Collins: A serial entrepreneur with experience in digital marketing and gaming tech through companies like Traffic Marketplace and Pala Interactive.
- Craig Sellars: An active figure in the crypto community and former CTO of Bitfinex. He also contributed to projects like Synereo, MaidSafe, and Factom.
Originally announced as Realcoin in July 2014, the first tokens were issued in October of that year. By November, the project rebranded to Tether and entered private testing with three variants: USTether (USD), EuroTether (EUR), and YenTether (JPY).
