Tether, the cryptocurrency company best known for its gold- and fiat-pegged stablecoins, announced the launch of a self-custodial digital wallet on April 14.
A stablecoin is a type of cryptocurrency that attempts to stabilize its value by pegging it to a “stable” asset such as a fiat currency like the US dollar or a commodity like gold.

The digital asset company offers several stablecoins:
-
USDT, a stablecoin pegged to the dollar
-
USAT, a stablecoin pegged to the dollar and regulated at the federal level
-
EURT, a stablecoin linked to the euro
-
XAUT, a stablecoin pegged to one troy ounce of gold
USDT is the world’s largest stablecoin with a market capitalization of $184.7 million. As the stablecoin needs to be backed by reliable liquid assets, Tether has become one of the largest holders of US debt, including short-term US Treasuries.
XAUT also needs to be backed by gold reserves, and Tether will become one of the largest holders of non-sovereign gold in the world. With a market capitalization of $2.6 billion, it is the world’s leading gold token.
As of December 31, 2025, Tether reported that the custodian of XAUT held a total of 520,089.350 fine troy ounces of gold.
According to Tether, the company’s technology is used by more than 570 million people in more than 160 countries as of March 2026. Tens of millions of new wallets are added every quarter.
As users demand a higher level of security for storing digital tokens, Tether has launched a digital wallet for this purpose.
Tether.wallet, a self-custodial digital wallet, puts Tether’s global financial infrastructure directly in the hands of its users, the company said.
The newly launched wallet supports the following digital assets:
-
USDT on Ethereum, Polygon, Plasma and Arbitrum
-
USAT on Ethereum
-
XAUT on Ethereum, Polygon, Plasma and Arbitrum
-
Bitcoin (BTC) on chain and via Lightning Network
Several other blockchains will be added to the wallet after this initial launch, Tether said.
Users can send funds using a simple identifier such as name@tether.me, as the system eliminates long and error-prone wallet addresses.
They can complete transactions without having separate network or gas tokens. Fees are paid directly to the asset being transferred, eliminating common friction points.
