Arbitrum has introduced Timeboost, a new transaction ordering system now live on Arbitrum One and Nova, giving users access to an optional express lane via private mempool bidding. This innovation helps reduce delays and mitigates risks like front-running by keeping the mempool private, while also creating a new revenue channel for the Arbitrum DAO.

Alongside Timeboost, Arbitrum has also unveiled Converge, a brand-new blockchain purpose-built for real-world assets (RWAs) and on-chain finance, developed in collaboration with Ethena Labs and Securitize. Converge launches with a massive $7 billion in tokenized assets, including $5B in Ethena’s USDe reserves and $2B from Securitize.

Key features of Converge include:

Stablecoin-based gas fees (USDe, USDtb) for predictable costs

100ms block times, with plans to lower this to 50ms

sENA staking for network security

Multi-language smart contract support (Solidity, Rust, C, C++) via the upcoming Stylus upgrade

Settlement powered by Celestia

These upgrades mark a major leap in scaling Ethereum Layer 2 ecosystems while bridging TradFi and DeFi through tokenized asset infrastructure.
