BNB Chain introduces rollup-as-a-service solution to expand its Layer 2 ecosystem

BNB Chain has unveiled a rollup-as-a-service (RaaS) solution to enable the expansion of custom Layer 2 networks in its ecosystem.

The RaaS will provide dapp projects with the infrastructure required to build cost-effective dedicated rollups on the BNB Smart Chain (BSC), including no-code deployment options.

BSC is the third-largest blockchain by total value locked, with $6.1 billion in TVL compared to Ethereum’s $56.7 billion and Tron’s $10.5 billion, according to DeFiLlama data.

“By combining the power of RaaS and the interconnectivity capabilities of our ecosystem, developers will have a comprehensive toolkit to build efficient and scalable Layer 2s on BSC,” the BNB Chain core development team said in a statement.

The BNB Chain ecosystem includes five distinct networks: BSC, a Layer 1 blockchain compatible with the Ethereum Virtual Machine; existing Layer 2 solutions opBNB and zkBNB; the data storage network BNB Greenfield; and the BNB Beacon Chain — though this is set to be phased out with its functionality migrated to BSC.

Layer 2s built on BSC network are connected via opBNB Connect — designed to facilitate interoperability within the ecosystem as part of its “One BNB” initiative to address the need for an integrated tech stack.
