Today marks a significant milestone with the official launch of the opBNB Mainnet. This new layer-2 solution is designed to enhance scalability and drastically reduce transaction costs, aligning with the broader goal of onboarding more users into the Web3 ecosystem.
Built on the Optimism OP Stack, opBNB is fully compatible with the Ethereum Virtual Machine (EVM). This allows developers to port their applications seamlessly while benefiting from significantly lower fees and higher throughput.
Testnet Performance and Achievements
The opBNB Testnet, launched earlier this year, demonstrated impressive results thanks to extensive community involvement and rigorous testing.
Key metrics from the testing phase include:
- Over 35 million on-chain transactions processed.
- Connections established with nearly 436,000 unique wallet addresses.
- Deployment of more than 150 decentralized applications (dApps).
- Daily active user base exceeding 6,000 participants.
The network also showcased outstanding technical performance:
- Average block time of approximately one second.
- Over 86,000 blocks processed per day.
- Sustained daily transaction volume between 100,000 and 150,000.
These results confirmed the network’s readiness for a full mainnet release.
Core Features of opBNB Mainnet
Before the mainnet launch, the development team focused on ensuring scalability, security, and affordability.
High Scalability and Low Costs
opBNB is engineered for high performance, achieving a peak capacity of 4,000 transactions per second (TPS). Its gas fees are among the lowest in the industry, averaging just 0.2 gwei. This translates to roughly $0.005 per transfer—making micro-transactions and everyday use economically feasible.
Robust Security Model
Security remains a foundational priority for opBNB:
- All transaction data is submitted and verified on the BNB Smart Chain, leveraging its robust validator set.
- A trustless mechanism ensures no single point of failure, even with a single sequencer currently in operation.
- Users can utilize deposit transactions for guaranteed inclusion in the layer-2 chain.
- A multi-signature wallet mechanism is in place for secure and transparent contract upgrades.

Growing Ecosystem and Developer Support
More than 150 projects have already committed to building on opBNB, with several protocols already live. The platform has attracted a vibrant developer community, supported by leading infrastructure and tooling providers.
Initiatives like the Hackvolution hackathon encouraged innovation, resulting in over 500 project submissions on the testnet. Regular AMAs and developer sessions have also fostered collaboration and knowledge-sharing.
Future Development Roadmap
The opBNB team is focused on continued improvement in decentralization, security, and usability.
Proof Mechanism Enhancements
Research is underway to improve fraud-proof efficiency within the OP Stack. This includes optimizing challenge periods and exploring zero-knowledge proof integrations.
Account Abstraction
Upcoming updates will introduce account abstraction, simplifying user interactions and reducing transactional complexity.
Integration with BNB Greenfield
opBNB will enhance data availability and interoperability with BNB Greenfield, enabling new cross-chain functionalities and use cases.
Decentralized Sequencer
To further improve fairness and censorship resistance, a decentralized sequencer is in active development.
Frequently Asked Questions
What is opBNB?
opBNB is a high-performance, low-cost Layer 2 blockchain built using the Optimism OP Stack. It is fully compatible with Ethereum and aims to make blockchain technology more accessible.
How does opBNB achieve such low gas fees?
By processing transactions off-chain and bundling them before finalizing on the BNB Smart Chain, opBNB reduces congestion and minimizes fees, often making transactions cost less than a penny.
Is opBNB secure?
Yes. opBNB uses a robust security model where all transactions are verified on the BNB Smart Chain. Ongoing internal and external audits help maintain a high security standard.
Can I use my existing Ethereum tools with opBNB?
Absolutely. Because opBNB is EVM-compatible, most Ethereum wallets, development frameworks, and dApps can be easily ported with minimal changes.
What types of applications are best suited for opBNB?
opBNB is ideal for high-frequency applications like gaming, social platforms, and decentralized exchanges where low cost and high speed are essential.
