Frens On Chain is a dynamic NFT platform where each NFT, called a "fren," is fully generated and stored on-chain. These NFTs evolve visually and behaviorally based on user interactions such as feeding, playing, and cleaning. This approach ensures permanence and uniqueness, as all data and changes are recorded on the blockchain, making the NFTs truly immutable and everlasting. The platform currently supports multiple Layer 2 and sidechain networks including Optimism, Base, Polygon, Arbitrum, and soon Linea, enabling broad accessibility and scalability.

Designed primarily for NFT platform developers and enthusiasts interested in on-chain generative art and interactive NFTs, Frens On Chain provides a novel way to engage users by combining gamification with blockchain permanence. Developers can integrate these NFTs into their projects or communities to offer users a living digital collectible that responds to care and attention. The fully on-chain nature eliminates reliance on off-chain metadata or centralized servers, enhancing security and longevity.

Getting started involves connecting to one of the supported chains through the platform’s dedicated portals and interacting with the NFTs via the provided interfaces. Comprehensive documentation is available to guide developers through the technical details of the smart contracts and interaction mechanics. The project’s open-source GitHub repository allows developers to explore the codebase and contribute or customize their own versions. Frens On Chain stands out by merging dynamic NFT behavior with full on-chain storage across multiple scalable networks.
