Unichain announced that its mainnet will be launched in early 2025, and a phased roadmap has been released. Since the launch of the Sepolia testnet in October, 50 million test transactions and 4 million test contract deployments have been completed. The mainnet will support permissionless fault proof, enhancing security and decentralization. On January 6, 2025, this feature will be enabled on the mainnet, and Rollup-Boost will be introduced to provide priority ordering and rollback protection for transactions. The experimental testnet will continue to test new features to ensure a smooth migration to the mainnet.
