INTRODUCING | Tether Launches Open-Source Toolkit to Let Anyone Build a Bitcoin and USDT Wallet Extensible to Any Token

Tether, the company behind the leading USDT stablecoin, has lauched a developer toolkit allowing anyone to build, deploy and use self-custodial wallets.

The Wallet Development Kit by Tether (WDK) is Tether’s open-source toolkit that empowers humans, machines and AI agents alike to build, deploy and use secure, multi-chain, self-custodial wallets that can be integrated anywhere from the smallest embedded device to any mobile, desktop and server operating system. WDK enables trillions of self-custodial wallets.

WDK provides a set of core libraries that give you the highest level of control and a wide range of user-interface templates and widgets to maximize your development and deployment speed.

Unlike commercial wallet frameworks that charge fees or lock developers into specific ecosystems, WDK by Tether is fully open-source and ecosystem-agnostic. Built with flexibility at its core, the framework enables anyone to create wallets that can operate across:

• Bitcoin
• Lightning Network
• EVM, and non-EVM blockchains, including
• Ethereum
• Arbitrum
• Polygon
• TON
• Solana

and more.

The wallet also supports:

• USDT
• XAUT
• USAT (coming soon), and
• Extensible to support any token

The wallet speaks to every blockchain or digital asset and integrates the USDT0 technology to expand and connect with any existing network.

WDK by Tether is available at https://wallet.tether.io/.

The wallet is built to power a wide range of DeFi primitives like:

• Savings
• Staking
• Swaps

and create comprehensive user experiences for any use case.

WDK also offers customizable user-interface templates and widgets that simplify the most complex aspects of wallet development, as well as:

• Secure key management
• Cross-chain asset transfers
• Messaging capabilities, and
• Stateful solutions such as real-time balance updates and transfer status tracking.

According to Tether, the Rumble Wallet is built on this technology but its only the beginning.

Tether says:

“The WDK enables a future with millions of wallets built on top of it, and trillions of AI agents, each with their own wallet, each able to interact, transact, and evolve.

Because when technology is open, creation has no limit.”
