The Arbitrum project has launched TimeBoost, a new way to order transactions on the Arbitrum One and Nova networks. The system adds “Express Lane” for faster transaction processing while keeping the network’s Mempool private.
At the same time, Arbitrum launched a time boost and also announced Converge. This is a new separate blockchain designed specifically for tokenized real-world assets, or RWAS, and distributed finance (DEFI). These moves illustrate a major step in expanding Arbitrum’s infrastructure as activity heats up at Ethereum Layer 2.
Time Boost currently lives in Arbitrum One and Nova.
This new transaction ordering policy allows users to bid for Express Lane Access. This allows Arbitrum to be included quickly while keeping private members.

How does Arbitrum’s time boost work?
With this new policy focused on TimeBoost, users aim to bid on faster transaction processing on Arbitrum One and Nova, reducing network latency. Instead of creating a speed race, the system offers an optional express lane for bidders. According to Arbitrum, the setup keeps Mempool private and reduces the risk of frontrunning and sandwich attacks common in public blockchains.
Beyond transactional orders, Time Boost also creates new revenue streams for Arbitrum Dao, the governing body of the project. By linking priorities to bidding, the network balances speed, efficiency and user privacy.
What is the new Converge blockchain?
Arbitrum’s wider ecosystem has been expanded with the launch of Converge, a new blockchain jointly developed by Ethena Labs and Securitize. The platform is designed to handle RWA and on-chain finance transfers and processing. A total of $7 billion in assets have moved to converge upon launch. Ethena’s USDE synthetic dollar reserve is $5 billion and Securitize’s tokenized assets amounts to $2 billion.
Instead of using volatile native assets for transaction fees, Converge relies on Stablecoins in particular on USDE and USDTB, particularly USDTB to maintain consistent gas costs. This approach covers the accuracy and affordability of companies handling tokenized assets.
Converge’s transactions settle in Celestia, with Layer 1 handling Stablecoin and NFT transfers. The chain starts with a block time of 100 milliseconds, and the upgrade plans to reduce it to an additional 50 milliseconds.
Also for security and development, Converge’s security comes from validators staking staking the Sena, a ingrained version of Ethena’s native token. Developers will also get planned stylus upgrades and allow smart contracts in various languages such as Solidity, Rust, C, C++.
