 ### Bridging - Deposit Transactions
 
-Deposit transactions don't exist on L1's, and are how transactions on an L2 can be initiated from the L1. Importantly, this is how bridge applications can get L1 ETH or tokens into an L2 OP-Stack chain. You can read more on deposit transactions [here](/stack/protocol/rollup/deposit-flow).

 ## Chain Finality
 
-Unlike L1s such as Ethereum OP-Stack chains have Unsafe, Safe, and Finalized Heads which indicate the state of finality for a given L2 block. Fault proofs do not impact the finalization of the L2 rollup, only the finalization of withdrawal transactions to the L1. You can read more about these [in the docs glossary](/resources/glossary#unsafe-l2-block).
