Financial technology is undergoing a tremendous transformation, and Huma Finance is at the forefront of this revolution. Their newly launched PayFi Stack is fundamentally changing our perception of financial infrastructure, transforming it into a highly modular and customizable system.

This innovative payment architecture is cleverly likened to 'financial Lego', consisting of six interchangeable and combinable layers, each of which can be adjusted or replaced according to needs. This design concept has not only attracted the participation of industry giants such as Solana, Stellar, and Circle, but has also transformed traditional rigid financial services into a flexible solution that can be freely customized.

In stark contrast to the rigidity of traditional financial systems, every layer of the PayFi Stack is meticulously designed to meet the diverse needs of modern finance. For example, the transaction layer utilizes Solana and Stellar as its foundation, significantly enhancing transaction speed and efficiency, allowing for the seamless handling of a large volume of transactions without delays. The currency layer introduces USDC as a stablecoin, with plans to incorporate yield-generating stablecoins in the future, providing users with additional value.

Security is also a major highlight of this system. The custody layer uses Multi-Party Computation (MPC) technology to ensure the immediacy and security of fund transfers, effectively addressing the long-standing cash flow issues that have troubled vendors.

But the most striking feature of PayFi Stack may be its application layer. It provides developers with an innovative platform to build various financial applications, from cross-border payroll payment systems to micro-lending tools, limited only by the developers' imagination.

The HUMA token plays a key role in this ecosystem; it is not only a tool for community governance, allowing holders to participate in the decision-making of new features, but it also enhances the security and stability of the network through a staking mechanism.

As the traditional credit card industry begins to pay attention to this innovation, we can foresee that Huma Finance's groundbreaking architecture is likely to redefine the future of financial services. It not only provides financial institutions with greater flexibility and efficiency but also brings a more personalized and convenient financial service experience to end users.
