-
-The Scroll protocol implements two core contracts `L1ScrollMessenger` and `L2ScrollMessenger` to enable cross domain messaging. The only entry to send cross domain message is to call the following function:
-
-```solidity
-function sendMessage(
-    address _to,
-    bytes memory _message,
-    uint256 _gasLimit
-  ) external payable
-```
-
-The function is attached in both messenger in layer 1 and layer 2. After that, the Sequencer will handle the rest part for you. We will explain the detailed workflow in the following docs.
-
-### Send Message from L1 to L2
-
-As described above, the first step is to call `L1ScrollMessenger.sendMessage` in layer 1. The `L1ScrollMessenger` contract will emit a `SentMessage` event, which will be notified by the Sequencer. The Sequencer will for the confirmation of the function call in layer 1. Normally, the Sequencer will wait for 10-20 blocks. After that, the Sequencer will initiate a transaction in layer 2, calling function `L2ScrollMessenger.relayMessage` and finally, the message is executed in layer 2.
-
-The execution in layer 2 may be failed due to out of gas problem. In such case, one can call `L1ScrollMessenger.replayMessage` to replace the message with a larger gas limit. And the Sequencer will follow the steps and execute the message again in layer 2.
-
-### Send Message from L2 to L1
-
-Similar to sending message from L1 to L2, you should call `L2ScrollMessenger.sendMessage` first in layer 2. The `L2ScrollMessenger` contract will emit a `SentMessage` event, which will be notified by the Sequencer. Unlike above, the Sequencer will first batch submit layer 2 transactions (or block) to `ZKRollup` contract in layer 1. Then the Sequencer will wait the proof generated by prover and submit the proof to `ZKRollup` contract in layer 1 again. Finally, anyone can call `L1ScrollMessenger.relayMessageWithProof` with correct proof to execute the message in layer 1.
-
-Currently, for the safety reason, we only allow privileged contracts to send cross domain messages. And only privileged accounts can call `L2ScrollMessenger.relayMessage`.

-# Overview
-
-![](./assets/overview.png)
-
-The above picture is the overview of the contract design. There are several components both in layer 1 and layer 2: L1/L2 Scroll Messenger, various L1/L2 Gateways and L1/L2 Gateway Router. Besides these, there is a Rollup component only in layer 1.
-
-The followings are the detailed docs for each component (docs are generated automatically by `@primitivefi/hardhat-dodoc` plugin):
-
-- [L1 Scroll Messenger](./apis/L1ScrollMessenger.md) and [L2 Scroll Messenger](./apis/L2ScrollMessenger.md): Main entry for sending and relaying cross domain message.
-- [Rollup](./apis/ZKRollup.md)
-- [L1 Gateway Router](./apis/L1GatewayRouter.md) and [L2 Gateway Router](./apis/L2GatewayRouter.md): Router contract for depositing/withdrawing Ethers and ERC20 tokens.
-- L1/L2 Gateways:
-  - [L1 Standard ERC20 Gateway](./apis/L1StandardERC20Gateway.md) and [L2 Standard ERC20 Gateway](./apis/L2StandardERC20Gateway.md)
-  - [L1 WETH Gateway](./apis/L1WETHGateway.md) and [L2 WETH Gateway](./apis/L2WETHGateway.md)
-  - [L1 ERC721 Gateway](./apis/L1ERC721Gateway.md) and [L2 ERC721 Gateway](./apis/L2ERC721Gateway.md)
-  - [L1 ERC1155 Gateway](./apis/L1ERC1155Gateway.md) and [L2 ERC1155 Gateway](./apis/L2ERC1155Gateway.md)
-- [ScrollStandardERC20Factory](./apis/ScrollStandardERC20Factory.md): The `ScrollStandardERC20` token factory used by `L2StandardERC20Gateway`.
-
-There are two main applications: Token Bridge and Cross Domain Messaging. You can find the documentations in the links below:
-
-- [Token Bridge](./TokenBridge.md): moving token from layer 1 to layer 2, or from layer 2 to layer 1.
-- [Cross Domain Messaging](./CrossDomainMessaging.md): sending data to layer 2 from layer 1, or sending data to layer 2 from layer 1. Basically, it will help to trigger function call cross layer. The token bridge also use cross domain messaging to achieve its functionality.

-# Bridge Token Between Layer 1 and Layer 2
-
-The Token Bridge of Scroll Protocol offers a way to move assets from layer 1 to layer 2 and back, including Ether, ERC20 token, ERC-721 token, ERC-1155 token, etc. The asset should be deposited and locked in layer 1 and then in exchange of the same amount of an equivalent token on layer 2. For example, if you deposit 1000 Ether in layer 1, you will get 1000 Ether in layer 2 for return. And if you withdraw 1000 Ether in layer 2, you will get 1000 Ether in layer 1 for return.
-
-The Ether and ERC20 tokens can be deposited or withdrawn using one single contract `GatewayRouter` (`L1GatewayRouter` in layer 1 and `L2GatewayRouter` in layer 2). The ERC-721 tokens and ERC-1155 tokens can be deposited or withdrawn using the corresponding `ERC1155Gateway` and `ERC721Gateway` in layer 1 or layer 2 (They may be integrated into `GatewayRouter` in the future).
-
-## Bridge Ether
-
-To bridge Ether from layer 1 to layer 2, one can use `L1GatewayRouter.depositETH`. This will transfer ethers to the `L1ScrollMessenger` contract on the layer 1 and credits the same amount of ether to you in layer 2 at the specified address.
-
-```solidity
-function depositETH(uint256 _gasLimit) external payable;
-
-function depositETH(address _to, uint256 _gasLimit) external payable;
-
-```
-
-In the layer 1, all deposited Ether will be locked in `L1ScrollMessenger` contract. It means your deposited Ether will firstly be transfered to `L1GatewayRouter` contract and then to `L1ScrollMessenger` contract.
-
-To withdraw Ether from layer 2 to layer 1, one can use `L2GatewayRouter.withdrawETH`.
-
-```solidity
-function withdrawETH(uint256 _gasLimit) external payable;
-
-function withdrawETH(address _to, uint256 _gasLimit) external payable;
-
-```
-
-In layer 2, the `L2ScrollMessenger` holds infinite amount of Ether at the beginning. All your withdrawn Ether will be transfered back to `L2ScrollMessenger`, just like the process in layer 1.
-
-In addition, you can actually call `sendMessage` from the `L1ScrollMessenger` or `L2ScrollMessenger` contract to deposit or withdraw Ether. The `L1GatewayRouter.depositETH` and `L2GatewayRouter.withdrawETH` are just alias for `L1ScrollMessenger/L2ScrollMessenger.sendMessage`.
-
-## Bridge ERC20 Tokens
-
-We use the similar design as [Arbitrum protocol](https://developer.offchainlabs.com/docs/bridging_assets#bridging-erc20-tokens) do. Several gateway contracts are used to bridge different kinds of ERC20 tokens, such as Wrapped Ether, standard ERC20 tokens, etc.
-
-We implement a `StandardERC20Gateway` to deposit and withdraw standard ERC20 tokens. The standard procedure to deposit ERC20 tokens is to call `L1GatewayRouter.depositERC20` in layer 1. The token will be locked in `L1StandardERC20Gateway` contract in layer 1. The the standard procedure to withdraw ERC20 tokens is to call `L2GatewayRouter.withdrawRC20` in layer 2 and the token will be burned in layer 2.
-
-For many other non-standard ERC20 tokens, we provide a custom ERC20 gateway. Anyone can implement such gateway as long as it implements all required interfaces. We implement the Wrapped Ether gateway as an example. To deposit or withdraw Wrapped Ether, one should first unwrap it to Ether, then transfer the Ether to `ScrollMessenger` just like Ether bridging.
-
-### Passing data when depositing ERC20 tokens
-
-The Scroll protocol offer a way to call another contract after depositing the token in layer 2 by calling `L1GatewayRouter.depositERC20AndCall` in layer 1. The ERC20 token in layer 2 implements the [ERC 677 Standard](https://github.com/ethereum/EIPs/issues/677). By using `transferAndCall` function, we can transfer the token to corresponding recipient in layer 2 and then call the recipient with passed data.
-
-```solidity
-function depositERC20AndCall(
-  address _token,
-  address _to,
-  uint256 _amount,
-  bytes memory _data,
-  uint256 _gasLimit
-) external;
-
-```
-
-Like Bridging Ether, all above functionality can be achieved by calling corresponding function in ERC20Gateway contract.
-
-## Bridge ERC-721/ERC-1155 Tokens
-
-The depositing/withdrawing ERC-721 or ERC-1155 tokens works very similar to ERC20 tokens. One can use the following function to deposit ERC-721/ERC-1155 tokens in layer 1.
-
-```solidity
-function depositERC1155(
-  address _token,
-  uint256 _tokenId,
-  uint256 _amount,
-  uint256 _gasLimit
-) external;
-
-function depositERC1155(
-  address _token,
-  address _to,
-  uint256 _tokenId,
-  uint256 _amount,
-  uint256 _gasLimit
-) external;
-
-function depositERC721(
-  address _token,
-  uint256 _tokenId,
-  uint256 _gasLimit
-) external;
-
-function depositERC721(
-  address _token,
-  address _to,
-  uint256 _tokenId,
-  uint256 _gasLimit
-) external;
-
-```
-
-One can use the following function to withdraw ERC-721/ERC-1155 tokens in layer 2.
-
-```solidity
-function withdrawERC1155(
-  address _token,
-  uint256 _tokenId,
-  uint256 _amount,
-  uint256 _gasLimit
-) external;
-
-function withdrawERC1155(
-  address _token,
-  address _to,
-  uint256 _tokenId,
-  uint256 _amount,
-  uint256 _gasLimit
-) external;
-
-function withdrawERC721(
-  address _token,
-  uint256 _tokenId,
-  uint256 _gasLimit
-) external;
-
-function withdrawERC721(
-  address _token,
-  address _to,
-  uint256 _tokenId,
-  uint256 _gasLimit
-) external;
-
-```
-
-To save the gas usage, we also provide a batch deposit/withdraw function, such as `batchDepositERC1155` and `batchDepositERC721`, by passing a list of token ids to the function.
