opBNB Opens Mainnet Doors for Developers
After months of development and testing involving over 400,000 user wallets on the testnet, opBNB has entered its final testing phase specifically tailored for infrastructure developers before its mainnet launch.

The final stage of opBNB before the Public Mainnet
On August 16, 2023, BNB Chain announced the commencement of the opBNB mainnet deployment — a Layer 2 scaling solution for BNB Chain — targeting infrastructure providers. This marks the initial steps towards the official community rollout expected by late August or early September 2023.

opBNB is an Ethereum Virtual Machine (EVM)-compatible extension built on Optimism's OP Stack platform, utilizing Optimistic Rollups to offer users in global decentralized finance numerous advantages, including:
Low gas fees and transaction costs
Fast and stable network speeds
Assured security measures
Scalability without limits
Binance launched the opBNB testnet on June 19, 2023, with expectations to support over 4,000 transactions per second.
According to BNB Chain, as of the announcement date, the opBNB testnet has recorded impressive metrics, including:
A total of 435,972 wallets connected to the network
Over 7 million on-chain transactions
opBNB has deployed over 40 dApps and processes over 86,000 blocks per day
Daily transaction volume ranges from 100,000 to 150,000 transactions
Transaction fees on opBNB can be adjusted to as low as 0.2 gwei, equivalent to $0.005
More than 6,000 daily active users
A significant milestone marking the continuous innovation of BNB Chain
BNB Smart Chain is part of the BNB Chain ecosystem, alongside:
BNB Beacon Chain (staking and governance layer of the BNB Chain ecosystem)
BNB Greenfield (decentralized data storage system)
zkBNB (a Layer 2 network based on Zk-Rollups) — currently in testnet phase after its launch in September 2022.
Following the mainnet launch, opBNB aims to achieve:
Enhanced fraud-proof systems — Evidence submitted by Verifiers to Layer-1 upon detecting suspicious transactions, used primarily in the Optimistic Rollup model
Implementation of account abstraction
Ensuring availability and seamless data interaction with the BNB Greenfield ecosystem
By focusing on these goals, opBNB aims to create a highly adaptable, decentralized blockchain network with high operational efficiency. This endeavor is expected to drive innovation and cross-platform digital applications, marking a significant milestone in improving BNB Chain's position within the decentralized finance ecosystem.
BNB Chain is steadily consolidating and enhancing its position. Compared to Ethereum, however, the "CZ ecosystem" remains relatively small compared to "Vitalik Buterin's ecosystem". The total value locked (TVL) or TVL of applications based on Ethereum is over $23 billion, while TVL of projects based on BNB Chain is approximately $3 billion, according to DefiLlama data.

The trend of building layer-2 solutions on Ethereum has exploded throughout 2023. Alongside solutions like Polygon zkEVM, zkSync Era, Linea, Scroll, and Taiko, centralized exchanges (CEX) such as Bybit, Coinbase, and OKX have each announced their own layer-2 solutions — Mantle, Base, and OKBChain, respectively.
Even projects originally conceived as layer-1, such as Celo and Shibarium, are planning to transition to layer-2 solutions.
