BNB Chain, the world’s largest smart contract blockchain in terms of daily active users, has today launched the opBNB testnet, an Ethereum Virtual Machine (EVM)-compatible L2 chain scalability solution to further democratize blockchain technology.

opBNB represents a significant milestone in BNB Chain’s innovation with its ability to move transactions to a layer 2, alleviating congestion and reducing transaction costs. Leveraging Optimistic Rollups, opBNB achieves enhanced scalability and affordability while maintaining a similar security level as L1. With better performance for users, opBNB addresses the challenges that have historically hindered the mass adoption of blockchain technology and unlocks new possibilities for developers and projects.

With support for over 4000 transfer transactions per second and an average transaction cost lower than 0.005 USD, opBNB is a highly scalable and secure platform that allows users to deposit funds from BSC and engage with applications and contracts on opBNB.
Arnaud Bauer, Senior Solution Architect at BNB Chain said: “opBNB is a key driver of BNB Chain’s commitment to delivering a seamless and efficient experience for users, developers, and projects. By providing more flexibility to applications wanting to be open platforms & ecosystems, we invite the community and dApp builders to try the testnet and contribute to the future of Web3.”

opBNB’s robust and EVM-compatible platform enables developers to easily create open ecosystems, facilitating the migration of applications to BSC and expanding their user base. Projects can leverage the improved throughput and significantly lower transaction costs, resulting in a superior user experience. Furthermore, opBNB’s enhanced scalability overcomes challenges previously faced by projects with high transaction volumes on BSC and enables them to thrive.

From enhanced scalability and EVM-compatibility to low gas fees and improved end-user experience, the launch of opBNB marks an important step towards creating an accessible and cost-effective blockchain ecosystem. Developers and projects are invited to explore the potential of opBNB, not only to benefit their project but also to enrich the broader BSC ecosystem and shape the future of blockchain technology.
