Sign launches a sovereign Layer 2 Stack based on BNB Chain to support national-level stablecoins and infrastructure development

Sovereign digital infrastructure provider Sign has announced the launch of the "Sign Sovereign Layer 2 Stack." This solution is built on the BNB Chain and opBNB Stack, aiming to assist governments in rapidly deploying secure and compliant national stablecoins and sovereign blockchain infrastructure within weeks.

The Sign Sovereign Layer 2 Stack combines the high performance of opBNB with the liquidity of BNB Chain, featuring the following four core characteristics: Digitalization of National Assets: Supports the tokenization and on-chain management of real-world assets (RWA) such as government bonds, land registries, and natural resources; Optimized Stablecoin Solutions: Offers gas-free stablecoin transfers, flexible fee exemption policies, and scalable distribution systems; Native Permission Control: Implements transaction interception and compliance control based on government dynamic sanction lists directly at the sequencer level; DID Ecosystem Integration: Built-in native proof and decentralized identity (DID) solutions support identity-based application development.

Sign stated that this architecture allows governments to retain sovereign control over transaction processing while leveraging the ecological liquidity of BNB Chain, aiming to establish BNB Chain as the preferred settlement layer for global sovereign infrastructure and stablecoins.
