BNB Chain Unveils New Layer 1 for AI-Powered Trading, Targets 2027 Mainnet

BNB Chain has announced plans to develop a new Layer 1 blockchain purpose-built for agentic trading, marking a major step toward infrastructure designed for AI-powered decentralized finance. Unveiled as part of the BNB Chain H2 2026 Tech Roadmap, the new network aims to deliver centralized exchange-like performance while preserving the transparency and self-custody of on-chain trading.

BNB Chain’s H2 2026 roadmap introduces a dedicated Layer 1 built for AI agents, high-speed trading, and next-generation blockchain performance.

The project is expected to launch a public testnet by the end of 2026, with a mainnet release targeted for early 2027. Rather than replacing the existing ecosystem, the new blockchain will operate alongside BNB Smart Chain (BSC), opBNB, and Greenfield, connected through an official native bridge while continuing to use BNB as the ecosystem’s primary asset. Recently, CZ clarified that he neither owns nor knows the BNB Chain meme coins $CZ, $TCC, and $AB.

Built for AI-Powered Trading

According to BNB Chain, the new Layer 1 is designed to support autonomous AI agents capable of executing trades, managing portfolios, providing liquidity, performing arbitrage, and interacting across decentralized finance protocols. Unlike BNB Smart Chain, which serves as a general-purpose smart contract network, the new blockchain is optimized specifically for ultra-low-latency execution and high-frequency on-chain trading.

To achieve this, the network plans to introduce sub-50 millisecond preconfirmation, enabling near-instant transaction acknowledgement before final settlement. BNB Chain is also targeting more than 100,000 transactions per second (TPS) and sub-one-second finality, bringing decentralized trading performance closer to centralized exchanges.

New Architecture to Reduce MEV

The roadmap introduces TxStream, a new transaction flow architecture that removes the traditional public mempool to reduce opportunities for front-running and sandwich attacks. In addition, PriorityLane will reserve transaction capacity for critical operations such as oracle price updates, liquidations, and cross-chain bridge transfers, helping maintain network reliability during periods of congestion.

Roadmap Builds on Recent Performance Gains

The announcement follows significant performance improvements across BNB Smart Chain. According to the H2 2026 roadmap, BNB Chain has already reduced BSC block intervals to 450 milliseconds while nearly doubling benchmark throughput to approximately 5,200 TPS. The network’s next objective is to achieve another twofold increase in mainnet performance, further improving scalability and execution speed.

Beyond the new Layer 1, the roadmap also includes continued optimization of BNB Smart Chain, development of a Reth-based execution client, expanded support for parallel execution, AI-focused developer tools, and research into post-quantum cryptography to strengthen long-term blockchain security.

With these initiatives, BNB Chain is positioning its ecosystem for the next generation of AI-native decentralized applications and autonomous financial agents, joining the broader industry push toward faster, more scalable blockchain infrastructure. BNB Chain recorded modest but steady growth throughout the week, with TVL increasing $4.85 billion to $4.97 billion during June 29–July 5.
