Users can now pay transaction fees using the asset they are sending, removing the requirement to hold a separate gas token. They can also send funds using human-readable identifiers in the format "[email protected]" instead of long blockchain addresses. These changes aim to reduce friction in digital asset transfers.
This functionality is delivered through tether.wallet, a self-custodial application launched by Tether. The app supports four assets: USDT, USAT, XAUT, and Bitcoin. It operates across multiple networks, including Ethereum, Polygon, Arbitrum, and Bitcoin's Lightning Network. Because the application is self-custodial, users retain full control of their private keys and sign transactions locally on their devices.
The product is built on Tether's open-source Wallet Development Kit (WDK). This toolkit allows third-party developers to integrate Tether and Bitcoin functions into websites, games, or apps without building key storage systems from the ground up. The WDK already powers the Rumble wallet for creator payments and peer-to-peer transfers.
Until now, Tether has operated primarily as a back-end layer providing liquidity and settlement for over 160 countries. Its technology currently reaches 570 million people, though mostly indirectly through exchanges and payment rails. The wallet provides a direct interface for humans, AI agents, and autonomous machines to handle payments.
