Through Blast's custom and public API services, BNB developers have instant access to the opBNB network. By leveraging Layer 2, with opBNB they are able to scale beyond the constraints of the BNB Smart Chain and obtain higher throughput and lower fees.
The opBNB is the Layer 2 network for the BNB Smart Chain, powered by bedrock version of the Optimism OP Stack. It enhances efficiency by transferring transaction processing and resource consumption off the BNB Smart Chain, while continuing to record data on the primary network. Users engage with the opBNB network by transferring assets from BSC and utilizing applications and contracts on opBNB.
Fundamentally, opBNB enables users to deposit and withdraw funds, employ smart contracts, and access network data with elevated throughput and reduced costs. By exploiting Layer 2, opBNB can expand beyond the limitations of the BNB Smart Chain, offering an enhanced experience for users. Large-scale Web3 applications such as games or social platforms, and high-frequency trading encounter obstacles when developed directly on Layer 1 chains.
The transaction fees on these Layer 1 chains remain high for most dApps, thus Layer 2 solutions, such as opBNB surface as more appropriate, more stable and easier to scale.
