Tether (USDT): The Complete Guide 2026
Tether (USDT) is the world's largest stablecoin and one of the most-traded crypto assets period. As a dollar stablecoin, USDT always trades at ~$1 USD, offering dollar stability on the blockchain, no bank account needed, no exchange rate risk.
USDT is issued by Tether Limited and backed by a portfolio of US Treasury bonds, cash, and other assets. It's available on dozens of blockchains and acts as the universal medium of exchange across the crypto ecosystem.
How Does Tether Work?
For every USDT issued, Tether Limited claims to hold an equivalent value in reserves, primarily US Treasury bonds and cash equivalents. Each USDT can theoretically be redeemed for $1.
Tether publishes periodic reserve attestations by auditors (currently BDO Italia). A full independent audit remains a community debate topic.
