opBNB

opBNB is a Layer 2 scaling solution designed to enhance the BNB Smart Chain (BSC) by leveraging the OP Stack, an optimistic rollup technology originally developed by Optimism. It offloads transaction processing from the BSC mainnet, enabling significantly higher throughput and lower gas fees while maintaining security by posting data back to the BSC. This architecture allows developers and users to benefit from faster transaction finality and reduced costs without sacrificing decentralization or security.

The platform supports a block gas limit of 100 million gas per second, enabling throughput of approximately 4,700 transactions per second with an average gas fee around $0.001. This performance is well suited for applications requiring high responsiveness such as gaming, decentralized exchanges, and NFT platforms. opBNB is fully EVM-compatible, allowing developers to deploy existing Ethereum-compatible smart contracts with minimal changes. It also integrates natively with the BNB ecosystem, including token economies and wallets.

Developers can get started quickly using comprehensive documentation, developer tools, and example projects provided by BNB Chain. The network supports seamless bridging of assets between BSC and opBNB, enabling liquidity and user migration. The modular design powered by the OP Stack allows for future upgrades and customizations tailored to specific workloads, such as dedicated chains optimized for gaming. opBNB is actively maintained with a growing ecosystem of dApps and developer support channels including Discord and community forums.
