Tether has launched its Wallet Development Kit (WDK), an open-source toolkit that empowers humans and AI agents alike to build, deploy and use self-custodial wallets.
What's the Scoop?
- For Humans and Machines: Tether's WDK isn’t just for humans; the company envisions that AI agents and autonomous systems will use the framework to manage their own resources and transact independently. “We imagine a world where humans, autonomous machines, and AI agents have the freedom to control their own finances,” said Tether CEO
Paolo Ardoino in a press release. - Universal Infrastructure: WDK will support multi-chain wallets across popular networks including Bitcoin, Lightning Network, Ethereum, Arbitrum, Polygon, TON, and Solana. Built-in USDT0 support will assist to create a seamless cross-network bridging experience.
- Total Developer Control: WDK offers customizable user-interface templates that simplify the most complex aspects of wallet development. Additionally, the toolkit will not charge fees or lock developers into specific ecosystems.
- Upcoming Integrations: The soon-to-be-launched Rumble Wallet and Tether’s own upcoming self-custodial solution will be constructed entirely on WDK.
🚀 Imagine a toolkit that lets anyone—humans, machines, AI—build unstoppable wallets.
