The Solana Foundation recently officially announced the launch of Kora, a new technical infrastructure designed to address transaction fees and authentication issues within the Solana ecosystem, thereby opening up many possibilities for improving user experience and facilitating the development of decentralized applications.
According to the Solana Foundation, Kora acts as a fee relay and signature node, allowing for more flexible and modern processing of transaction fees and authentication signatures compared to previous solutions. The most notable aspect of Kora is its ability to support fee-free transactions for end users, as well as allowing fee payments using any Token , including stablecoins, instead of being limited to SOL as before. This is considered a significant step in lowering the barrier to blockchain access, especially for new users unfamiliar with holding native Token to pay network fees.
Before Kora, implementing flexible payment mechanisms and remote authentication on Solana faced many limitations. While Solana 's account model technically allowed for these features, the market lacked standardized, ready-to-deploy, and easily integrated solutions for developers. This forced many projects to build their own systems, which was both costly and posed security risks. Kora, developed by the Solana Foundation, aims to fill this gap, providing a complete solution that can be immediately applied to applications within the ecosystem.
Besides covering all transaction fees on behalf of users, Kora also allows projects to customize the Token used for fee payments, opening up possibilities for building new economic models. For example, an application could allow users to pay fees using the project's own Token , or using stablecoins to avoid price fluctuations. Furthermore, Kora supports moving transaction signing operations to a separate, secure environment, minimizing the risk of private key leaks and enhancing security for end users.
