What is opBNB?

opBNB is a high-performance Layer 2 scaling solution for the BNB Smart Chain, powered by the bedrock version of Optimism OP Stack. It works by offloading transaction processing and resource usage from the BNB Smart Chain while maintaining data posting to the underlying mainnet. Users interact with opBNB by depositing funds from BSC and using applications and contracts on opBNB.

Key Features and Advantages

​

Optimistic Rollup Technology

• Processes transactions off-chain while maintaining BSC chain security
• Bundles multiple transactions into single batches for main chain submission
• Reduces computational load on BSC for faster and cheaper transactions
• Supports up to 5,000 transactions per second (TPS)

​

Transaction Efficiency

• Lower transaction fees through off-chain processing
• Faster transaction confirmations
• Enhanced user experience for DApps and DeFi platforms
• Ideal for micro-transactions
