With Seal, Walrus Becomes The First Decentralized Data Platform With Access Controls

Seal is now available with Walrus Mainnet, offering encryption and access control for anyone building on the protocol. As the data layer for Web3, Walrus already provides decentralized infrastructure for data storage, availability, and programmability. With the launch of Seal, Walrus now delivers a solution for integrating programmable data access into any app at any scale .

Web3's transparency means data is public by default. For many, that is a benefit, while others require privacy or access controls. Walrus with Seal enables builders to create products that not only require verifiable data but also data privacy, fine-grained access, and secured sharing. A whole world of Web3 apps becomes possible when these technologies work together.

Making privacy part of public infrastructure

Transparency is the core ethos of Web3, but the idea that your data is visible to everyone can present challenges for builders and users alike. For those who need to manage potentially sensitive data, it's a nonstarter. Anyone who wants to keep data confidential either has to use a centralized service or build a custom setup–not only time-consuming and expensive, but also a barrier to entry for newcomers exploring onchain data management solutions.

Thanks to the launch of Seal, Walrus is the first decentralized data platform to natively offer onchain access control. Developers can now protect sensitive data, define who can access it, and enforce those rules entirely onchain.

Unlocking transformative use cases

With the addition of programmable data access control, Walrus now enables entirely new categories of applications that were previously impossible in decentralized environments. For example:

• AI Dataset Marketplaces: Organizations can now share proprietary training data or fine-tuned models while enforcing strict access policies. Data providers can monetize their assets without losing control, creating new revenue streams in the AI economy.
• Token-Gated Subscription Services: Premium content such as exclusive podcast episodes, videos, or educational materials can be encrypted and made accessible only to verified subscribers, enabling sustainable creator economies on Web3.
• Dynamic Gaming Content: Game developers can reveal encrypted in-game content, story elements, or assets only when players achieve specific milestones, creating more engaging and interactive gaming experiences.

Partners are driving real-world adoption

Dozens of Walrus-powered projects are already using Seal, demonstrating the immediate practical value of onchain encryption and access control. Examples include:

Tokenizing AI Infrastructure

Inflectiv is building a data platform for AI that uses Walrus with Seal to gate and tokenize datasets. This allows contributors to protect and monetize their data while providing developers and enterprises with secure, trusted assets for AI and agent-driven applications

Trustless Gaming Mechanics

Vendetta is a fully onchain multiplayer strategy game that leverages Walrus with Seal to secure in-game data and mechanics. Players gain true ownership of their progress and assets while competing in skill-based, tamper-proof battles within a transparent and secure game economy.

Securing AI Agent Infrastructure

A full stack for decentralized data

Sui and Walrus, now with Seal, aim to accelerate the transition from Web2 to Web3, creating a comprehensive infrastructure stack for the decentralized internet. Sui provides the high-performance blockchain foundation. Walrus with Seal delivers scalable data management, availability, and access control essential for enterprise adoption. This integrated approach addresses the full spectrum of requirements for building sophisticated Web3 applications that can compete with Web2 counterparts.

The momentum for building full-stack apps continues to grow.

The future of Web3 apps relies upon data that's intelligently controlled, privately managed, and enterprise-ready. That's why it will be built with Walrus and Sui.
