ZetaChain Upgrades to 2.0, Launches Anuma to Build a New AI × Privacy Platform
- Core Insight: ZetaChain has launched its AI interoperability layer, ZetaChain 2.0, and the first privacy-focused AI interface based on this layer, Anuma (in beta). The aim is to address the fragmentation in the AI ecosystem through a unified platform, allowing developers to build applications that run across models and chains while protecting user privacy by default.
- Key Elements:
- ZetaChain 2.0 is a brand-new AI interoperability layer. Its core components include a unified routing AI portal and a protocol-level privacy memory layer for encrypting user information.
- The platform provides a developer SDK that bundles privacy memory, cross-model interoperability, and global monetization capabilities, aiming to lower the barrier for developers building privacy-first applications.
- The first consumer-facing application, Anuma, demonstrates an experience where users can switch between AI models without losing conversation context, with their memory data kept private and under their control. It is currently open for public waitlist registration.
- Background data shows the AI ecosystem is highly fragmented, with only about 9% of consumers paying for multiple AI assistants. Meanwhile, the ZetaChain network has processed over 225 million transactions.
- The project is driven by core contributors including Ankur Nandwani, who co-created the BAT token ecosystem for the Brave browser. It completed a $27 million funding round in 2023.
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. Concurrently, ZetaChain also launched ZetaChain 2.0, a novel 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-founded 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 notes that ChatGPT reached 100 million users in just two months, and OpenAI reports that its weekly active users have hit 800 million by the end of 2025. 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 integration, routing, state, and billing infrastructure, while user privacy and data are often shared across applications, agents, and model providers.
ZetaChain was born to solve fragmentation in Web3 by supporting omnichain applications—those that can natively access assets like BTC and execute operations across multiple blockchains—creating a unified platform. By the end of 2025, the ZetaChain network had expanded to over 11.5 million users, processing more than 225 million transactions. With ZetaChain 2.0, this unification concept extends further into AI, enabling applications to operate across chains and models with 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, featuring 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 persistent 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 emphasizing 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. Its goal is to empower developers to easily build privacy-centric applications and agents, achieving cross-session continuity, connecting to multiple model providers, and supporting global monetization capabilities from on-chain settlements to traditional payment service providers, without the need for teams to build custom infrastructure themselves.
Anuma: The First Consumer-Facing Application Demo
Anuma is the first consumer-facing AI interface built on ZetaChain 2.0. The product provides access to multiple leading AI models through a unified interaction interface, 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 via the public waitlist.
Ankur Nandwani, a core contributor to ZetaChain, stated: "Brave and BAT proved that a privacy-by-default approach can succeed at consumer scale. We've already unified the blockchain experience at scale, processing over 225 million transactions. ZetaChain 2.0 extends this philosophy to AI, enabling the next generation of applications and agents to operate across models and chains with privacy, authorizable memory, and global monetization 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, monetize, and preserve private memory without building 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.
