Tether, the issuer of the world's largest stablecoin USDT, is launching tether.wallet – a self-custodial wallet built on open-source technology aimed at mainstream users, content creators, and autonomous AI agents.
The company has until now operated as the technological backbone of the crypto ecosystem – known for USDT, a stablecoin with a market capitalisation of $185 billion – without consumer-facing products of its own. The launch of tether.wallet marks a clear departure from that role: Tether is moving from infrastructure provider to a company competing directly for users' attention and daily transactions.

The wallet supports USDT on Ethereum, Polygon, Plasma, and Arbitrum, as well as XAUT, USAT, Bitcoin, and the Lightning Network. Tether states that the underlying technology – the Wallet Development Kit (WDK) – is already used by 570 million users globally as of March 2026.
The framework is open-source and available to third-party developers. According to CoinDesk, it is already in use in the wallet of video platform Rumble, where it handles creator payments and peer-to-peer transfers between users.
Instead of long, cryptic blockchain addresses, users can send money to simple, readable addresses – much like an email address. This significantly lowers the barrier for people without a technical background.
Tether has also eliminated the need for separate gas tokens – small amounts of cryptocurrency required to cover transaction fees on many blockchains. Fees are instead paid in the currency being transferred, removing a persistent source of frustration for mainstream crypto users.
The most ambitious part of Tether's positioning has nothing to do with humans. CEO Paolo Ardoino argues that autonomous AI agents will need their own self-custodial wallets – and that bitcoin and stablecoin infrastructure will become the transaction layer for these agents operating independently.
"tether.wallet is the people's wallet – ready for a future where tens of billions of humans, machines, and trillions of AI agents will transact at the speed of light," Ardoino writes in the press release.
The vision is ambitious, but not without logic: as AI systems increasingly operate autonomously and handle payments on behalf of users or businesses, demand for this kind of transaction infrastructure will grow.
The Block reports that Tether has invested in content platform Whop to support stablecoin payments to creators via the same framework. The connection between wallet, development platform, and strategic investments suggests Tether is positioning itself as a shared technological foundation for the next generation of financial applications – not just as an issuer, but as a platform.
The wallet is available at wallet.tether.io.
