What it is
Tether USD (USDT) is a fiat-backed stablecoin issued by Tether, designed to track the value of one US dollar. Per Tether's own terms, each token in circulation is one hundred percent backed by Tether's reserves and redeemable at face value less fees by verified customers.
Technology & consensus
USDT is issued as a digital token across multiple blockchains; it launched on the Bitcoin blockchain via the Omni Layer protocol, and Tether's current terms confirm multi-chain issuance while noting redemptions ceased on Omni, Bitcoin Cash SLP, Kusama, EOS and Algorand effective September 1, 2025.
Token utility
USDT is used as a dollar-denominated medium of exchange, settlement asset on trading platforms, and vehicle for transfers and remittance; it carries no governance rights or fee-accrual function.
Key risks & notes
Reserve transparency rests on quarterly attestations rather than a full audit, and Tether states reserve composition is at its sole discretion; holders bear counterparty risk to Tether with no insured-deposit protections. Tether's own site now presents the original whitepaper as historical interest only, stating it creates no legal obligations.
