BNB Chain is developing a new Layer 1 aimed at agent trading, with the goal of launching the mainnet in 2027

According to The Block, BNB Chain is developing a new Layer 1 blockchain aimed at Agentic Trading and has released the first detailed architectural information after months of research and development on the project.

According to the technical roadmap for the second half of 2026 disclosed by BNB Chain, the new chain will run in parallel with the existing BNB Chain ecosystem, aiming to achieve a transaction preconfirmation of less than 50 milliseconds, designed to provide an execution experience close to centralized exchanges (CEX), while retaining the advantages of on-chain self-custody and transparency.

In terms of technical architecture, the new chain will remove the traditional public mempool and introduce a transaction transmission mechanism called "TxStream," which directly sends transactions to block producers to reduce latency and minimize MEV extraction behaviors such as sandwich attacks.
