Tether releases open-source wallet development kit for global self-custody

Tether, a stablecoin issuer, today released an open-source Wallet Development Kit (WDK) designed to enable developers to create self-custodial wallets supporting Bitcoin, Lightning, and various stablecoins.

The toolkit facilitates the development of wallets for humans, machines, and AI systems, emphasizing self-custody and integration with assets including USD₮ and XAU₮. The WDK aligns with Tether’s broader mission to promote global financial freedom through open-source infrastructure.

Tether has previously supported open-source initiatives by contributing to ecosystems that advance Bitcoin and freedom tech, consistent with its focus on self-custodial infrastructure development.
