USDTUSD
Tether / United States dollar
crypto Composite

Tether is fiat-collateralized stablecoin that offers individuals the advantages of transacting with blockchain-based assets while mitigating price risk. Tether is primarily issued on the Ethereum and Bitcoin blockchains and corresponds on a 1:1 basis with US Dollars sitting in bank accounts. Tether relies on a proof-of-reserves system to ensure that reserve assets match circulating tokens. This requires a third-party to audit Tether's bank accounts on a regular basis to show that U.S. dollar reserves are held in an amount equal to outstanding tokens. Tether uses an IOU issuance model where each USDT represents a claim for $1.00 held in the Tether's reserves which users can redeem at any time. On Bitcoin, USDT tokens are issued via the Omni Layer protocol, which is a protocol built as a layer over Bitcoin that allows for the issuance of tokens representing any kind of asset. On Ethereum, USDT tokens are issued using the ERC-20 protocol standard for creating tokens on Ethereum. ERC-20 tokens include a common set of rules that define how a token can be transferred, approved, and requested.
