Sign Launches Sovereign Layer 2 Stack on BNB Chain for National Stablecoin Infrastructure

Sovereign digital infrastructure provider Sign unveiled its Sovereign Layer 2 Stack on Nov. 21, built on BNB Chain and opBNB Stack to enable governments to deploy compliant national stablecoins and blockchain infrastructure within weeks. The solution features tokenization of real-world assets including government bonds and land registries, gas-free stablecoin transfers with customizable fee exemptions, sequencer-level transaction controls based on government sanction lists, and native decentralized identity integration. Sign said the architecture allows governments to maintain sovereign control over transaction processing while leveraging BNB Chain's ecosystem liquidity, positioning BNB Chain as a settlement layer for global sovereign infrastructure.
