 ## OptimismMintableERC20Factory

 Address: `0x4200000000000000000000000000000000000012`
 
 The `OptimismMintableERC20Factory` is responsible for creating ERC20 contracts on L2 that can be
-used for depositing native L1 tokens into. These ERC20 contracts can be created permisionlessly
+used for depositing native L1 tokens into (`OptimismMintableERC20`). These ERC20 contracts can be created permisionlessly
 and implement the interface required by the `StandardBridge` to just work with deposits and withdrawals.
 
-Each ERC20 contract that is created by the `OptimismMintableERC20Factory` allows for the `L2StandardBridge` to mint
-and burn tokens, depending on if the user is depositing from L1 to L2 or withdrawing from L2 to L1.

+depositing from L1 to L2 or withdrawing from L2 to L1.
+
+The factory will deploy using `CREATE3`, where the salt will depend on the user inputs:
+`remoteToken`, `name`, `symbol`, and `decimals`.
+The use of `CREATE3` over `CREATE2` removes any dependence on the compiler.

+
+The `OptimismMintableERC20Factory` will include a `deployments` mapping
+to store the `remoteToken` address for each deployed `OptimsimMintableERC20`.
