 ## Pause functionality
 
 The `OptimismPortal` points to a `SuperchainConfig` smart contract which has a privileged `GUARDIAN` address that can pause and unpause L2-to-L1 transactions from being executed.
-The `SuperchainConfig` contract is shared implmentation across the Superchain and all Optimism governed chains point to it and any OP Stack chain can opt to point their `SuperchainConfigProxy` to this shared implmentation. 
+The `SuperchainConfig` contract is a shared implementation across the Superchain. All Optimism-governed chains point to it, and any OP Stack chain can point its `SuperchainConfigProxy` to this shared implementation.
 L2-to-L1 transactions allow users and smart contracts on the OP Stack chain to send messages to the L1 parent chain.
 Pause functionality allows a `GUARDIAN` to halt L2-to-L1 transaction execution for the OP Stack chain in question.
 L1-to-L2 transactions are not affected by pause functionality.
