ZetaChain today announced that Anuma , a privacy-focused AI interface built on ZetaChain 2.0, has officially entered beta and opened up a public shortlist of candidates. Simultaneously, ZetaChain also launched ZetaChain 2.0, a new AI interoperability layer designed to help developers build applications and agents that can run across AI models, preserve user privacy, and achieve global monetization without requiring backend infrastructure.
Ankur Nandwani, a core contributor to ZetaChain, co-founded Basic Attention (token name 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 concept of "default privacy and user control" to the next generation of AI-powered consumer interfaces, further emphasizing the importance of preference information and memory in user experience.
The adoption of AI is accelerating at an internet-scale pace: McKinsey points out that ChatGPT reached 100 million users within two months , and OpenAI reports that its weekly active users will reach 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 a lock-in effect 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 created to address the fragmentation problem in Web3 by supporting universal applications—those capable of natively accessing assets like Bitcoin and performing operations across multiple blockchains—to achieve a unified platform. By the end of 2025, the ZetaChain network had expanded to over 11.5 million users and processed over 225 million transactions. With ZetaChain 2.0, this unified vision is further extended to AI, enabling applications to run across chains and models, while incorporating built-in access control and privacy management.
The core components of ZetaChain 2.0 include:
- AI Portal : A unified routing and execution layer that allows applications to access multiple AI model providers without being locked in, while also having built-in availability guarantees, fallback mechanisms, and cost/performance optimization features;
- Privacy Memory Layer : A protocol-level memory system used to encrypt and control user information, enabling a continuous experience across sessions while ensuring that users have complete control over access permissions to applications and smart agents.
Developer SDK and Platform
ZetaChain 2.0 is a developer-centric platform that emphasizes scalability. In addition to protocol components, ZetaChain has released a developer SDK that packages privacy memories, cross-model interoperability, and monetization primitives into a complete toolkit. Its goal is to enable developers to easily build privacy-focused applications and agents, achieve cross-session continuity, connect to multiple model providers, and support global monetization capabilities from on-chain settlement to traditional payment service providers, without requiring teams to build their own customized infrastructure.
Anuma: First Consumer-Oriented Application Demo
Anuma is the first consumer-facing AI interface built on ZetaChain 2.0. This product connects to multiple leading AI models through a unified interface, allowing users to switch between different models without losing conversation content. Its design ensures that users' memory data remains private and under their control. Currently, users can apply for early access through a public waiting list.
Ankur Nandwani, a core contributor to ZetaChain, stated: “Brave and BAT have proven that solutions with privacy as the default setting 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 next-generation applications and agents to operate across models and chains, with privacy, authoritative 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, and GSR.
About ZetaChain
ZetaChain is a general-purpose layer for AI and Web3, enabling developers to build cross-chain and cross-model applications without building their own infrastructure, achieving monetization while protecting privacy memory. With its native connectivity to mainstream blockchains and an AI interoperability technology stack driven by the Private Memory Layer, ZetaChain is laying the foundation for next-generation applications, agents, and digital experiences.
