ZetaChain today announced that Anuma, a privacy-centric AI interface built on ZetaChain 2.0, has officially entered its beta phase and opened a public waitlist. Simultaneously, ZetaChain introduced ZetaChain 2.0, a new AI interoperability layer designed to help developers build applications and agents that can operate across AI models, preserve user privacy information, and achieve global monetization without the need for backend infrastructure.
Ankur Nandwani, a core contributor to ZetaChain, co-created Basic Attention Token (BAT), which powers the Brave browser ecosystem with over 100 million monthly active users. Brave made private browsing mainstream by blocking ads and trackers by default. Anuma applies this philosophy of "privacy and user control by default" to the next generation of consumer AI interfaces, emphasizing the growing importance of preference information and memory in the user experience.
The adoption of AI is accelerating at internet scale: McKinsey noted that ChatGPT reached 100 million users in just two months, and OpenAI reported that by the end of 2025, it had reached 800 million weekly active users. Despite this, the ecosystem remains highly fragmented, with only about 9% of consumers paying for multiple mainstream AI assistants. This leads to lock-in at the model level, forcing developers to repeatedly rebuild the same integrations, routing, state, and billing infrastructure, while user privacy and data are often shared across applications, agents, and model providers.
ZetaChain was born to address fragmentation in Web3 by supporting omnichain applications—applications that can natively access assets like BTC and perform operations across multiple blockchains—creating a unified platform. By the end of 2025, the ZetaChain network had expanded to over 11.5 million users and processed more than 225 million transactions. With ZetaChain 2.0, this unification concept extends further into AI, enabling applications to operate across chains and models while incorporating built-in permission controls and privacy information management.
The core components of ZetaChain 2.0 include:
- AI Gateway: A unified routing and execution layer that allows applications to access multiple AI model providers without lock-in, with built-in availability guarantees, fallback mechanisms, and cost/performance optimization;
- Private Memory Layer: A protocol-level memory system for encrypting and permissioning user information, enabling continuous experiences across sessions while ensuring users retain full control over access permissions for applications and agents.
Developer SDK and Platform
ZetaChain 2.0 is a developer-centric platform with a strong emphasis on scalability. In addition to the protocol components, ZetaChain has released a developer SDK that packages privacy memory, cross-model interoperability, and monetization primitives into a complete toolkit. The goal is to enable developers to easily build privacy-centric applications and agents that achieve cross-session continuity, connect to multiple model providers, and support global monetization capabilities—from on-chain settlements to traditional payment services—without the need for teams to build custom infrastructure.
Anuma: The First Consumer-Facing Application Demo
Anuma is the first consumer-facing AI interface built on ZetaChain 2.0. The product provides a unified interaction interface that integrates multiple leading AI models, supports switching between different models without losing conversation context, and is designed to ensure that user memory data remains private and user-controlled. Currently, users can apply for early access through the public waitlist.
Ankur Nandwani, a core contributor to ZetaChain, stated: "Brave and BAT demonstrated that a privacy-by-default approach can succeed at consumer scale. We have already unified the blockchain experience at scale, processing over 225 million transactions. ZetaChain 2.0 extends this concept to AI, enabling the next generation of applications and agents to operate across models and chains, with privacy, authorizable memory, and global monetization capabilities by default."
In 2023, ZetaChain announced the completion of a $27 million funding round, with investors including Blockchain.com, Human Capital, VY Capital, Sky9 Capital, Jane Street Capital, VistaLabs, CMT Digital, Foundation Capital, Lingfeng Capital, GSR, and others.
About ZetaChain
ZetaChain is a universal layer for AI and Web3, enabling developers to build applications that operate across chains and models, ensuring privacy memory while achieving monetization, without the need to build their own infrastructure. With native connectivity to mainstream blockchains and an AI interoperability stack powered by the Private Memory Layer, ZetaChain is laying the foundation for the next generation of applications, agents, and digital experiences.
