Tether Unveils Open-Source Wallet Kit to Empower Developers Across Six Blockchains
Tether has designed to assist developers build self-custodial wallets for mobile, desktop, embedded devices, and autonomous systems. The toolkit includes beginer wallets for iOS and Android and aims to make multi-chain wallet features such as DeFi, swaps, lending, and cross-chain transfers easier to deploy.
WDK is ecosystem-agnostic by design. Tether says the framework supports BTC and the Lightning Network, along with multiple EVM and non-EVM chains including ETH, Arbitrum, Polygon, TON, and Solana. The kit also integrates Tether’s own USDT₀ scaling tools and plans to support additional Tether assets in the future.
The beginer wallets demonstrate how developers can implement non-custodial key management, multiple mnemonic backup options, and a DeFi module that covers USDT operations, swapping, and lending. Tether also showcased a modular UI component set and cross-platform building blocks aimed at reducing development time for common wallet functionalities.
Tether framed the WDK as infrastructure not only for human users but also for machines and AI agents capable of transacting autonomously. CEO Paolo Ardoino said that open-sourcing the code allows anyone to audit, contribute, and build white-label wallet answers without vendor lock-in—positioning the kit as a foundation for what he described as “trillions” of self-custodial wallets.
The launch aims to expand self-custody adoption and reduce integration costs for applications that require wallet functionality. By providing reference mobile wallets, Tether enables smaller teams to build secure products more efficiently, while larger projects can reuse or audit the codebase to accelerate their own development cycles.
WDK is available now through Tether’s wallet hub and GitHub repository. The company said the project is free to use, fully auditable, and extensible—allowing developers, enterprises, and sovereign projects to tailor it to their specific compliance and user experience needs.
Tether’s Market Involvement
Alongside its , Tether is taking notable steps to strengthen its market position.
The company recently , settling a long-running dispute over BTC collateral liquidations. The move closes a major legal chapter and removes lingering uncertainty around Tether’s exposure to failed lenders.
At the identical time, reports suggest Tether is in talks with round that could value the firm at around $500 billion. Such a deal would mark one of the largest capital raises in the crypto industry’s history.
