🤝 Sign Launches Sovereign Layer 2 Stack on BNB Chain

Sign, a leading provider of sovereign digital infrastructure services, announced the launch of its “Sign Sovereign Layer 2 Stack” on November 21, 2025. This specialized solution, built upon the foundation of BNB Chain and the opBNB Stack, is engineered to enable national governments to swiftly, securely, and compliantly deploy national-level stablecoins and establish sovereign blockchain infrastructure—all within a matter of weeks.

This rollout significantly reinforces BNB Chain’s commitment to positioning itself as the preferred settlement layer for global sovereign infrastructure and stablecoin initiatives. The Sign Sovereign Layer 2 Stack effectively combines the high performance capabilities of opBNB with the vast liquidity pool of the BNB Chain ecosystem, featuring four critical core characteristics designed specifically for state-level adoption:

National Asset Digitalization: The framework provides robust support for the tokenization and on-chain management of Real-World Assets (RWA) owned by the government. This includes vital assets such as government bonds, land registries, and natural resources, simplifying their management and potentially enhancing their liquidity.

Optimized Stablecoin Solutions: The solution offers advanced features for stablecoin deployment, including Gas-Free Stablecoin Transfers, flexible fee exemption policies, and a highly scalable distribution system, which addresses common issues related to high transaction costs and network congestion.

Native Permission Control: It implements direct, sovereign control at the Sequencer layer. This allows governments to enforce strict compliance by dynamically implementing transaction interception and monitoring based on official, real-time sanctions lists or regulatory requirements, ensuring transactions adhere to national and international laws.

Decentralized Identity (DID) Ecosystem Integration: The architecture integrates native proof mechanisms and Decentralized Identity (DID) solutions. This built-in identity layer supports the development of sophisticated, identity-based applications and enhances the security and accountability of all on-chain activity.

Sign states that this architecture is designed to allow governments to maintain complete sovereign control over transaction processing and data management, while simultaneously leveraging the vast network effects, tooling, and liquidity provided by the established BNB Chain ecosystem. This development signifies that RWA tokenization and blockchain adoption at the nation-state level are rapidly transitioning from theoretical concepts to deployable global market realities, accelerating the integration of digital finance into governmental operations.
