BNB Chain Is Building a New Layer-1 for AI and Trading

Key Takeaways

  • BNB Chain is building a new layer-1 for high-frequency trading and autonomous AI agents, with a testnet planned for late 2026 and a mainnet in early 2027.
  • The network is targeting preconfirmations below 50 milliseconds, more than 100,000 transactions per second, and block finality in under one second.
  • The new chain removes the public mempool and adds features like privacy, account abstraction, gas sponsorship, and passkey signing.

BNB Chain is developing a new layer-1 blockchain designed for high-frequency trading and autonomous AI agents. The company plans to roll out a public testnet by the end of 2026, with mainnet expected in early 2027. The new chain will sit alongside the existing BNB Chain ecosystem rather than replacing it.

Faster Execution

The new network is built to move transactions much faster than what traders usually get on-chain today. BNB Chain is aiming for preconfirmations under 50 milliseconds, throughput above 100,000 transactions per second, and block finality in less than one second. The idea is to bring self-custodied trading closer to the speed users expect from a crypto exchange.

A key part of that design is the removal of the public mempool. Instead of sitting in a public queue, transactions will be streamed directly to the block leader. BNB Chain says that should cut latency and help limit front-running, a familiar problem in markets where speed can decide who gets the better price.

AI Agents and Infrastructure

The timing also lines up with a broader shift in crypto, where teams are building infrastructure for autonomous AI agents that can send payments, execute transactions, and trade without constant human oversight. Coinbase rolled out accounts for AI agents last month, and stablecoins are increasingly being viewed as the payment layer for this kind of software.

BNB Chain has already upgraded the performance of BNB Smart Chain. In the first half of 2026, block times fell to 450 milliseconds from 750 milliseconds, while benchmark throughput climbed to about 5,200 transactions per second from roughly 2,800. The new layer-1 is meant to take that further with execution-layer tools such as just-in-time compilation and strength reduction.

More Features for Developers

The roadmap also reserves blockspace for services like oracles, liquidations, and cross-chain bridges. Native privacy, account abstraction, gas sponsorship, transaction batching, scheduled execution, and passkey signing are also included. BNB Chain is also exploring quantum-resistant security, although that work is still in the research stage. The long-term goal is to let users enable quantum-safe protection without changing their wallet address or breaking existing apps.

For European crypto readers, the bigger picture is clear: the market is moving toward not just faster settlement, but also more automation and stricter demands around execution. If BNB Chain delivers on these technical targets, it could raise the bar for use cases where speed, privacy, and programmability all matter at once.
