Tether (often referred to by its currency codes, USD₮ and USDT, among others) is a cryptocurrency stablecoin, launched by the company Tether Limited Inc. in 2014. As of January 2024, Tether's website lists fourteen protocols and blockchains on which Tether has been minted.
Tether has been criticized for a lack of transparency and verifiability of its claimed fiat reserves. In 2021, the company was fined by regulators for only maintaining full reserves during 27.6% of the days in the period from 2016 to 2018 as well as for failing to present audits showing sufficient asset reserves.

As of March 2024, Tether had over $100 billion in circulation, leading to concerns about it being a systemic risk for cryptocurrency markets and threatening the stability of wider financial markets.
Tether Limited is owned by the British Virgin Islands-based company iFinex Inc., which also owns the Bitfinex cryptocurrency exchange...
