According to Foresight News, Layer2 technology research and data website L2BEAT announced the launch of the Build Your Own Rollup (BYOR) tool. BYOR is a simplified version of a sovereign Rollup that makes the code easy to read and understand. BYOR is currently deployed on the Holesky testnet, and can implement functions including fee sorting, sending and getting status to L1, deleting invalid transactions, viewing account balances, sending transactions, and viewing transaction status.

Compared to Optimistic and ZK rollups, sovereign rollups do not verify the state root on Ethereum and rely only on it for data availability and consensus. This prevents a trust-minimized bridge between L1 and BYOR, but greatly simplifies the code. The BYOR codebase consists of three programs: smart contracts, nodes, and wallets, which when deployed together allow end users to interact with the network.
