Cross Program Library (CPL)
‍

‍

The Cross Program Library (CPL) is a vital component of the PAW Chain ecosystem. It consists of a collection of on-chain programs specifically developed for the tri-layer parallel runtime environment. These programs are rigorously tested against PAW Swap's implementation of the tri-layer architecture, known as PAW Swap - runtime, and deployed on its mainnet.

As PAW Chain gains wider adoption, CPL will play a crucial role in ensuring interoperability across different implementations of the tri-layer architecture. The library is designed to be flexible and portable, and the PAW Chain community is committed to accepting patches and updates to maintain compatibility across various implementations.
