Tether Unveils Open-Source Wallet Kit to Power Trillion Non-Custodial Wallets

Tether, the fintech leader behind the world’s largest stablecoin, is preparing to launch a fully open-source, non-custodial crypto wallet template as part of its new Wallet Development Kit (WDK). According to CEO Paolo Ardoino, this innovative toolkit could enable the creation of up to one trillion blockchain wallets.

Announced on May 9, 2025, the upcoming wallet infrastructure aims to make non-custodial wallets accessible to a global developer community. Built for interoperability, the WDK will support seamless cross-chain transactions and include intuitive UX features to simplify crypto transfers across decentralized networks.

A standout feature of the wallet is its "gasless transactions" capability, powered by account abstraction. This allows users to execute transactions without paying gas fees, making crypto more accessible. Unlike many other wallet systems, Tether’s solution prioritizes user sovereignty by removing API keys entirely, ensuring only the user has access to their funds.

Designed for nearly any blockchain—not just Ethereum Virtual Machine (EVM)-compatible chains—the template is intended to promote widespread adoption of self-custody in the Web3 ecosystem. Ardoino hinted that the release is imminent, though no specific date has been disclosed.

This initiative aligns with Tether’s broader strategy of expanding its influence beyond stablecoins. The company has made bold investments across AI, mining, and media, including a $775 million investment in video platform Rumble. It is also backing Twenty One, a Bitcoin investment platform targeting institutional players.

Tether’s non-custodial wallet push reinforces its commitment to decentralization, security, and user empowerment, while opening new frontiers for crypto wallet development on a global scale. As crypto adoption grows, tools like the WDK may redefine how billions interact with digital assets.
