BNB Chain is developing a new Layer 1 blockchain focused on agentic trading, adding a separate execution environment for autonomous trading agents, high-frequency onchain orders and self-custody market activity.
The chain will run alongside the existing BNB Chain stack rather than replacing BNB Smart Chain, opBNB or BNB Greenfield. The target is an execution layer that gives users and AI agents faster order handling while keeping assets in self-custody, narrowing the gap between centralized exchange speed and onchain settlement.
The architecture targets transaction preconfirmation in under 50 milliseconds. That would move BNB Chain’s trading stack closer to CEX-style responsiveness, where execution latency can decide whether an automated strategy remains profitable or gets picked off by faster market participants.
The new chain is expected to remove the traditional public mempool and use a transaction transmission system called TxStream. Under that model, transactions are sent directly to block producers instead of sitting publicly visible before inclusion.
Private order flow is central to the agentic trading pitch. Public mempools expose pending transactions, making trading bots and human users vulnerable to front-running, sandwich attacks and strategy copying. A private mempool gives trading agents a cleaner route for execution because orders are not broadcast to competing searchers before they reach block production.
BNB Chain has already been building around confidential trading and agent execution. Its privacy stack includes mempool exposure protection for AI trading agents, while its AI agent infrastructure supports autonomous onchain activity across trading, payments and data access.
The new Layer 1 extends that work from tooling into base-layer execution. It gives BNB Chain a dedicated venue for autonomous trading systems that need fast settlement, lower information leakage and programmable control without handing custody to a centralized exchange.
BNB Chain’s AI-agent strategy has expanded across identity, payments, wallets and autonomous execution. The network’s agent framework covers onchain AI agents that transact, trade and access data, giving the new Layer 1 a user category beyond ordinary DeFi traders.
That push sits inside a wider crypto trend toward machine-driven payments and trading. Coinbase’s x402 protocol processed 160 million agentic payments, while BNB Chain has been building around AI-agent identity, crypto payments and automated execution.
BNB Chain also enters the project from a strong retail and stablecoin base. The network led stablecoin user activity earlier this year as Polygon, Base, Celo and Arbitrum competed for low-cost payment and transfer flows.
The new Layer 1 is scheduled for testnet by the end of 2026, with mainnet targeted for early 2027.
