On August 14, Spark, a second -layer protocol (L2) based on the Lightning Network (LN), was integrated into the tool made by Tether, Wallet Development Kit (WDK).
That collaboration It allows “developers to now create currencies ready for production with native support for Lightning, Bitcoin, Stablecoins and more, through a single API without a state.”
For developers, the availability of an API (application programming interface) without a state (which does not keep persistent information) simplifies the creation of purses.
The API without a state provided by WDK acts as a bridge that allows programmers to develop Wallets compatible with Bitcoin, Stablecoins and the LN without the need to build all the underlying infrastructure from scratch.


This reduces the safety risks associated with the storage of sensitive data, such as private keys, and encourages the adoption of rapid transactions through Network Lightning. For users, means Access to Wallets “Intelligent” With automation capabilities, according to Paolo Ardoino, CEO of Tether.
Spark is a technology that facilitates the connection of applications with the Lna second layer (L2) of Bitcoin that allows to process rapid and low -cost transactions.
In addition to acting as a bridge with LN, Spark optimizes Bitcoin’s scalability by allowing transfers Off-Chain (out of the chain) of BTC and Stablecoins through an infrastructure that supports instant and global payments.
He WDK Tether is a set of tools designed for developers to believe Wallets where users have total control over their private keys and transaction processes.
Paolo Ardoino, CEO of Tether, highlighted the objective of this alliance:
“The future is an unpredictable chaos, instability or prosperity. But with WDK and Spark, we can build programmable and resilient monetary systems that serve people, machines and communities equally. This integration makes Bitcoin Lightning truly accessible, allowing instant global transactions without compromising custody or privacy.”

For his part, David Marcus, CEO of Lightspark, said that the purpose is to offer developers a Simple route to integrate the Bitcoin fast payment network in the applications that people already use.
With this step, Tether and Lightspark enable an infrastructure that combines the liquidity and stability of the stablecoins with the speed and efficiency of Lightning Network, bringing the practical use of Bitcoin and other digital assets to a greater number of users and use cases.
