What is Tether (USDT)?
Tether (USDT) is an asset-backed crypto stablecoin launched in 2014 byTether, Limited (originally named “Realcoin”). Its core design objective is to peg its value to the U.S. dollar at a 1:1 ratio, thereby providing price stability in the highly volatile cryptocurrency market.The emergence of USDT has provided cryptocurrency traders with a tool to hedge against market risks, store value, and make cross-border payments without having to leave the cryptocurrency ecosystem.
USDT’s Operational Mechanism and Technical Foundation
USDT was initially issued on October 6, 2014, on the Bitcoin blockchain via the Omni Layer protocol. As the cryptocurrency ecosystem has evolved, Tether has expanded its issuance to multiple blockchain networks to meet the needs of various use cases.As of July 2026, the majority of USDT exists as ERC-20 tokens on Ethereum; it is also widely distributed across mainstream blockchain networks such as Tron, Solana, and Polygon. This multi-chain deployment strategy has significantly enhanced USDT’s liquidity and usability.
In July 2026, Tether announced that it would bring USDT back to the Bitcoin network natively via the RGB protocol, with the aim of integrating it into the Lightning Network to improve payment efficiency and reduce transaction costs, thereby further expanding its applications within the Bitcoin ecosystem.
Reserve Composition and Transparency Controversy
