Trillion wallets, no strings attached: Tether’s Paolo Ardoino on game-changing release

Wallet Development Kit by Tether, one of the biggest crypto companies and the USDT stablecoin issuer, is close to being 100% open-source. Such a statement was made by Tether CEO and co-founder Paolo Ardoino on his X today, Oct. 4, 2025.

Ardoino expects “trillions” of new self-custody wallets to be created with the instruments of the new WDK. As a result, the new generation of cryptocurrency users will have “pure freedom” in their journeys in crypto.

As covered by U.Today previously, for the first time, such ambitions were shared by Tether in May. The new WDK was introduced as a product for gasless transactions with no API key sharing and a seamless UX/UI.

Tether’s revolutionary WDK: What do we know so far?

While Tether’s Wallet Development Kit is nearing an open-source release, its documentation can shed some light on what this tool will bring to the table.

Technically, it would be an out-of-a-box service capable of handling interactions with multiple blockchains without compromising self-custody:

WDK is a developer-first framework to create cross-chain wallets that are secure, extensible, and production-ready. It provides a single, stateless API to interact with Ethereum, Bitcoin, TON, and Spark (Lightning Network)—abstracting blockchain-specific complexity while keeping developers in full control of keys and data.

Thanks to account abstraction tech, it would be able to implement gas subsidies to make operations gasless for end users. Also, wallets created with this WDK will be equipped with all DeFi-centric functions like swaps, token transfer tools and cross-chain messaging.

Frameworks for Solana (SOL) and Tron will be included into next releases, as per the official documentation portal of Tether WDK.
