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 reliability has made it a cornerstone of the digital asset ecosystem, serving traders, investors, and decentralized applications across multiple blockchains.
Built initially on the Bitcoin blockchain via the Omni Layer protocol, Tether has evolved into a multi-chain powerhouse. Today, USDT operates across more than 15 major blockchain networks—including Ethereum, Tron, Solana, Polygon, Avalanche, and Kusama—enabling fast, low-cost global transactions with high interoperability.

The Evolution of Tether: From Realcoin to Global Dominance
Tether was originally launched in 2014 under the name Realcoin by co-founders Reeve Collins, Craig Sellars, and Brock Pierce. The project rebranded to Tether later that year and entered private testing with support for three fiat-backed versions: USTether (USD), EuroTether (EUR), and YenTether (JPY).
The technology behind Tether traces back to the Mastercoin Foundation, an early Bitcoin-based protocol aimed at enabling advanced financial functions on blockchain. Brock Pierce, a founding member of Mastercoin, played a key role in shaping Tether’s vision alongside Craig Sellars and Reeve Collins.
Initially issued on the Bitcoin network through the Omni Layer—a platform for creating and transferring digital assets—Tether gradually expanded beyond its roots. While it originated on Bitcoin, Ethereum quickly became the dominant network for USDT due to its robust smart contract capabilities and widespread adoption.
Over time, Tether Limited, the company behind USDT, began deploying tokens across high-performance blockchains to meet growing demand for scalability and efficiency.
Key Milestones in Tether’s Blockchain Expansion
- 2021: Tether Limited minted a record 2 billion USDT in a single week amid surging crypto market activity. This period reflected rising institutional interest in digital assets and declining trust in traditional financial systems.
- November 2021: USDT launched on Avalanche, one of the fastest and most cost-effective smart contract platforms. Backed initially by Bitfinex, this integration enabled faster and cheaper USDT transfers.
- April 2022: Tether was added to the Kusama network—the 10th blockchain to support USDT. As a canary network for Polkadot, Kusama allows experimental deployments before they move to the main Polkadot chain, making this integration a strategic step toward broader ecosystem compatibility.
- May 2022: USDT went live on Polygon, Ethereum’s leading layer-2 scaling solution. At the time, Polygon hosted over 19,000 decentralized applications (DApps) and had more than $5 billion in total value locked (TVL). With lower fees and faster transactions than Ethereum’s mainnet, Polygon became the 11th blockchain to support USDT.
These expansions underscore Tether’s commitment to accessibility, speed, and cross-chain utility—critical factors in Web3’s growth.
How Tether Works: Stability, Reserves, and Token Mechanics
Unlike volatile cryptocurrencies such as Bitcoin or Ethereum, USDT maintains price stability by being fully backed by reserves. While early versions were said to be 100% backed by cash deposits, Tether Limited now discloses a diversified reserve composition.
As of recent updates, Tether’s reserves include:
- Fiat currencies (primarily USD)
- Cash equivalents
- Short-term deposits
- Commercial paper
- U.S. Treasury bills
- Corporate bonds
- Secured loans
- Precious metals
- Other qualified investments
This diversified model ensures liquidity and resilience while maintaining a 1:1 peg with the U.S. dollar. Tether publishes daily reserve reports and undergoes quarterly attestation by independent accounting firms to enhance transparency.
Issuance and Redemption Process
Tether Limited controls the minting and burning of USDT tokens:
- When users deposit U.S. dollars into Tether’s reserves, an equivalent amount of USDT is created.
- When holders redeem their USDT for fiat, those tokens are permanently destroyed.
This mechanism ensures that every circulating USDT token corresponds to a real-world asset held in reserve.
Currently, there are approximately 69.36 billion USDT in circulation, with a total supply slightly below that figure. The difference accounts for tokens held by Tether Limited for operational purposes.
Importantly, USDT has no maximum supply cap. However, new tokens are only issued when sufficient collateral is deposited—ensuring each token remains fully backed.
