According to Foresight News, OP Labs recently announced on Twitter that the OP mainnet has launched a multi-chain upgrade to enhance the security and upgradability of the super chain. Officials also stated that the cost of deploying chains will now be reduced, and L1 contracts on multiple chains can be upgraded through a single transaction. In addition, the new on-chain "queryable" function allows users to query all L1 contract addresses programmatically using SystemConfig.
