The Sign team has introduced its sovereign Layer-2 architecture, “SIGN Stack,” built on BNB Chain and opBNB. It is designed specifically for governments deploying digital infrastructure and compliant national stablecoins.

SIGN Stack offers customizable Sequencer permissions, a DID identity framework, gas-free stablecoin transfers, and on-chain support for national Real-World Assets (RWA).

Its broader goal is to position BNB Chain as the global settlement layer for sovereign blockchain infrastructure.
