BNB Chain Announces Launch of opBNB Mainnet

BNB Chain announces the public launch of it’s Layer 2 scaling solution, opBNB

September 13th 2023 – BNB Chain, the community-driven blockchain ecosystem of Layer-1 and Layer-2 scaling solutions with the world’s largest smart contract blockchain in terms of monthly active users, today announced the public mainnet launch of opBNB. 

As it builds to bring the next one billion users to Web3, the Ethereum Virtual Machine (EVM)-compatible L2 chain scalability solution based on Optimism OP Stack expands the BNB Chain ecosystem to provide cheaper gas fees across the industry, and further democratize blockchain technology. The announcement happened during a side event hosted by BNB Chain at Token 2049 with industry leaders, influencers and media in attendance.

The opBNB mainnet launch follows a comprehensive testing phase where more than 35 million on-chain transactions and 150+ dApps were deployed on the testnet. After successfully meeting all the required criteria which included achieving a peak 4K TPS (Transactions Per Second) and successfully completing a stress test campaign to ensure robustness and reliability, the opBNB mainnet was open to builders.

BNB Chain offers specialized support for projects building on opBNB, including monetary incentives like Builder Grants and Gas Grants, and non-monetary incentives like Kickstart and the Liquidity Program. They also provide dedicated marketing support, enhanced security through DappBay, and 24/6 tech support for opBNB projects. This comprehensive support aims to drive growth within the opBNB ecosystem.

Projects can integrate with opBNB through BNB Chain’s extensive developer tutorial and dedicated technical support. The  integration documentation providing the detailed guidelines to streamline the process can be accessed here. 

Arno Bauer, Senior Solution Architect at BNB Chain said, “Scalability and security are the top priorities of opBNB. Before opening the mainnet to the public, stringent criteria had to be met. This included High Availability (HA), a stable 4K Transactions Per Second (TPS), rigorous stress testing, reduced gas costs under 0.2 gwei, fast finality under 1 second, and enhanced security with multiple external audits. Reaching these milestones ensured that opBNB met its goal to pave the way for a robust and efficient blockchain ecosystem that prioritizes a high-quality developer experience."

To provide its developer community with enhanced tools and infrastructure, the opBNB network received support from leading infra and tooling partners to improve the developer experience. 

Notably, BNB Chain will be issuing the Genesis NFTs to celebrate the mainnet launch where users will enjoy VIP benefits such as priority access to activities such as partner airdrops and whitelist slots. In addition, recipients of the $50k BNB airdrop will receive rewards to their opBNB mainnet addresses within the next two weeks. 

To mark the launch of the opBNB mainnet, BNB Chain is rolling out its biggest ecosystem event of 2023, the ‘opBNB Airdrop Marathon’ alongside 15+ ecosystem partners. The two month series of airdrop activities will give users access to a prize pool with 1-3 airdrop activities being launched every week. More details will be released soon.
