BNB Chain has revealed plans to build a brand-new Layer 1 blockchain specifically designed for the next generation of AI-powered agentic trading, signaling one of the network’s biggest infrastructure upgrades since its launch. According to the project’s newly released H2 2026 technical roadmap, the blockchain will operate alongside the existing BNB Chain ecosystem while delivering sub-50 millisecond transaction pre-confirmation, eliminating the public mempool, and significantly reducing front-running opportunities for automated trading systems. A public testnet is expected by the end of 2026, with a full mainnet launch targeted for early 2027.
The announcement reflects the rapidly growing role of artificial intelligence in decentralized finance as autonomous trading agents increasingly execute transactions, manage portfolios, and interact with blockchain protocols without constant human oversight. Rather than simply increasing throughput, BNB Chain is designing an entirely new execution environment optimized specifically for AI-driven financial activity.
Unlike traditional Layer 1 networks designed primarily for decentralized applications, the new blockchain is being engineered specifically for autonomous financial agents.
According to BNB Chain’s roadmap, the new network will feature:
Removing the public mempool prevents pending transactions from being openly visible before execution, helping protect traders from Maximal Extractable Value (MEV) attacks such as sandwich trading and front-running that have become increasingly common across public blockchain networks.
The new blockchain is not replacing BNB Smart Chain.
Instead, it will function as an additional Layer 1 network operating alongside the current BNB ecosystem, allowing developers to choose the infrastructure best suited for their applications.
BNB Chain says the existing network will continue supporting decentralized finance, gaming, NFTs, and consumer applications, while the new Layer 1 focuses primarily on institutional-grade financial infrastructure and autonomous AI trading systems.
The roadmap reflects a broader shift taking place across Web3.
Rather than serving only human users, blockchains are increasingly preparing for autonomous software agents capable of:
As AI systems become more sophisticated, blockchain infrastructure must evolve to support high-speed machine-to-machine financial activity without sacrificing security or decentralization.
BNB Chain says the project focuses on three major technical priorities:
One of the most notable design decisions is eliminating the public mempool, which has long been criticized for allowing sophisticated traders to monitor pending transactions and exploit slower participants.
Combined with ultra-fast confirmation times, the architecture aims to create a more efficient trading environment for both AI agents and institutional market participants.
Development is already underway.
According to the roadmap:
BNB Chain plans to continue refining performance throughout the remainder of 2026 before opening the network to developers for testing. The phased rollout is intended to ensure stability before production deployment.
The announcement highlights how competition between blockchain networks is evolving.
Rather than competing solely on transaction speed and fees, leading ecosystems are increasingly specializing around particular industries and applications.
Recent examples include:
Industry analysts believe future blockchain adoption will increasingly be driven by specialized infrastructure designed for specific market segments rather than one blockchain attempting to serve every use case
