Although^0.8.25is a valid pragma, you may consider pinning the compiler version or confirming that this version aligns with your project’s tested environment.
47-58: Consider using SafeERC20 and emit an event for locking.
Using OpenZeppelin’sSafeERC20can simplify error handling by reverting on transfer failures, removing the need to check the booleansuccess. Emitting aLockAndMintevent can provide better traceability for off-chain tools.Example diff:
+import {SafeERC20} from "@openzeppelin/contracts/token/ERC20/utils/SafeERC20.sol"; contract LockboxSuperchainERC20 is SuperchainERC20 { ... function lockAndMint(uint256 amount_) external { - IERC20 originalToken = IERC20(_originalTokenAddress); + SafeERC20 originalToken = SafeERC20(_originalTokenAddress); require(block.chainid == _originalChainId, "Wrong chain"); - bool success = originalToken.transferFrom(msg.sender, address(this), amount_); - require(success, "No tokens to lock, no mint either"); + originalToken.safeTransferFrom(msg.sender, address(this), amount_); + // Emitting event for better traceability + emit TokensLocked(msg.sender, amount_); _mint(msg.sender, amount_); }
59-68: Consider emitting an event and using SafeERC20 for redemption.
Like the locking flow, an event (e.g.,TokensRedeemed) andSafeERC20can improve reliability and transparency, ensuring transfers either succeed or revert without manual return checks.

public/tutorials/LockboxSuperchainERC20.sol (5)
49-59: Add events for important state changes.The contract doesn't emit any events when tokens are locked and minted. Events are crucial for tracking contract activity off-chain and for UIs to react to contract state changes.
Consider adding events like:
+ event TokensLocked(address indexed user, uint256 amount); + event TokensRedeemed(address indexed user, uint256 amount); function lockAndMint(uint256 amount_) external { // ... existing code ... require(success, "No tokens to lock, no mint either"); _mint(msg.sender, amount_); + emit TokensLocked(msg.sender, amount_); } function redeemAndBurn(uint256 amount_) external { // ... existing code ... bool success = originalToken.transfer(msg.sender, amount_); require(success, "Transfer failed, this should not happen"); + emit TokensRedeemed(msg.sender, amount_); }
14-27: Validate token decimals match.The constructor accepts a
decimals_parameter but doesn't verify if it matches the decimals of the original token. A mismatch could lead to unexpected behavior when locking and minting tokens.Consider adding validation:
constructor( string memory name_, string memory symbol_, uint8 decimals_, address originalTokenAddress_, uint256 originalChainId_) { require(originalTokenAddress_ != address(0), "Invalid token address"); require(originalChainId_ != 0, "Invalid chain ID"); + + // Validate decimals match the original token + IERC20 originalToken = IERC20(originalTokenAddress_); + try IERC20Metadata(originalTokenAddress_).decimals() returns (uint8 originalDecimals) { + require(decimals_ == originalDecimals, "Decimals mismatch"); + } catch { + // If the original token doesn't implement decimals(), we can't validate + } _name = name_; _symbol = symbol_; _decimals = decimals_; _originalTokenAddress = originalTokenAddress_; _originalChainId = originalChainId_; }Note: This requires importing the IERC20Metadata interface:
import {IERC20Metadata} from "@openzeppelin/contracts/interfaces/IERC20Metadata.sol";
56-56: Fix typo in comment.There's a typographical error in the comment: "necessariy" should be "necessary".
- // Not necessariy if the ERC-20 contract reverts rather than reverting. + // Not necessary if the ERC-20 contract reverts rather than returning false.
1-70: Add NatSpec documentation for better code clarity.The contract lacks comprehensive documentation which would make it more accessible to developers. Consider adding NatSpec comments for the contract and its functions.
Example for the contract:
+/** + * @title LockboxSuperchainERC20 + * @dev A contract that locks original ERC20 tokens and mints equivalent Superchain ERC20 tokens. + * This allows existing ERC20 tokens to be upgraded for interoperability with Superchain. + */ contract LockboxSuperchainERC20 is SuperchainERC20 {Example for a function:
+/** + * @notice Locks original tokens and mints equivalent Superchain tokens + * @param amount_ The amount of tokens to lock and mint + * @dev This function can only be called on the original chain. + * The caller must have approved this contract to transfer the original tokens. + */ function lockAndMint(uint256 amount_) external {
49-59: Handle potential accidental token transfers.If users mistakenly transfer tokens directly to this contract (not using
lockAndMint), those tokens will be permanently locked with no way to recover them.Consider adding a function to rescue tokens sent directly:
+/** + * @notice Allows recovery of tokens mistakenly sent to the contract + * @param token The address of the token to recover + * @param amount The amount of tokens to recover + * @param recipient The recipient of the recovered tokens + * @dev This function can only be called by the contract owner. + * It should not be used for the original token managed by this contract. + */ +function rescueTokens( + address token, + uint256 amount, + address recipient +) external onlyOwner { + // Prevent rescuing the tokens that are meant to be locked + require(token != _originalTokenAddress || block.chainid != _originalChainId, + "Cannot rescue locked tokens"); + + IERC20(token).transfer(recipient, amount); +}Note: This requires implementing access control (e.g., OpenZeppelin's Ownable) for the contract.

61-69: Implement checks-effects-interactions pattern in redeemAndBurn.Similar to
lockAndMint, theredeemAndBurnfunction should follow the checks-effects-interactions pattern to protect against potential reentrancy, even though the burn happens before the transfer.The current implementation already follows this pattern since it performs the state change (
_burn) before the external interaction (transfer). This is the correct ordering.

🛠️ Refactor suggestion
Consider implementing reentrancy protection for external calls.
The lockAndMint function makes an external call (transferFrom) before updating the contract state (_mint). This ordering is susceptible to reentrancy attacks if the original token contract is malicious or compromised.
Apply this diff to implement checks-effects-interactions pattern:
function lockAndMint(uint256 amount_) external {
IERC20 originalToken = IERC20(_originalTokenAddress);
require(block.chainid == _originalChainId, "Wrong chain");
- bool success = originalToken.transferFrom(msg.sender, address(this), amount_);
-
- // Not necessariy if the ERC-20 contract reverts rather than reverting.
- // However, the standard allows the ERC-20 contract to return false instead.
- require(success, "No tokens to lock, no mint either");
- _mint(msg.sender, amount_);
+ // Mint first (effects)
+ _mint(msg.sender, amount_);
+
+ // Then transfer tokens (interactions)
+ bool success = originalToken.transferFrom(msg.sender, address(this), amount_);
+
+ // Not necessary if the ERC-20 contract reverts rather than returning false.
+ // However, the standard allows the ERC-20 contract to return false instead.

| This guide explains how to upgrade an ERC20 to a [`SuperchainERC20`](https://github.com/ethereum-optimism/optimism/blob/develop/packages/contracts-bedrock/src/L2/SuperchainERC20.sol) that can teleport across the Superchain interop cluster quickly and safely using the [`SuperchainTokenBridge`](https://github.com/ethereum-optimism/optimism/blob/develop/packages/contracts-bedrock/src/L2/SuperchainTokenBridge.sol) contract. For more information on how it works, [see the explainer](/stack/interop/superchain-erc20). |

There was a problem hiding this comment.
Thoughts on starting with for overview steps:
1.) Categorize your token
Determine which of the following categories best describes your token's current state.
Category A: The token already exists and is upgradable via a proxy pattern.
Category B: The token already exists and is immutable.
Category C: The token is new and is not deployed anywhere.
2.) Prepare to deploy
Category A: Upgrading an existing ERC-20 token that uses the proxy pattern
Category B: Upgrading an existing ERC-20 token that is immutable
Category C: Goes to existing deploy SuperchainERC20 tutorial
Then we get into the relevant sections?

maybe easier is just show a flow chart
[Has the token been deployed]
No -> Deploy a SuperchainERC20
Yes -> Is it upgradable? No -> Lockbox Yes -> Proxy upgrade

189-189: Possible Typo in "knowlege"The term "knowlege" may be a misspelling of "knowledge." If this was intentional for a specific context, please confirm; otherwise, consider correcting it.
193-193: Verify the Term "Lockboxe"The entry "Lockboxe" is added here and appears linked to the Lockbox contract introduced in the PR. Please confirm that this spelling is intentional and matches related documentation and smart contract names.
322-323: Evaluate Duplicate "proxied" EntriesThe list includes both "Proxied" (line 322) and "proxied" (line 323). If the capitalization difference is intended to capture case-sensitive variations, it’s fine. Otherwise, consider removing the duplicate to avoid redundancy as highlighted by the static analysis tool.

1-5: Frontmatter metadata completeness:
The frontmatter currently includes only the title, language, and description. For regular pages, the guidelines require additional fields such as topic, personas, categories, and content_type. Please add these fields to ensure proper metadata and consistency across documentation.
21-31: Details "About this tutorial" block:
The details section is useful; however, there is a minor typo in “Prerequisite knowlege” – consider correcting it to “Prerequisite knowledge.”
40-46: Commented-out developer note:
There is a JSX-style commented block with developer notes. Please decide whether this note should remain in the published documentation. If it’s only meant for internal context, consider removing it or relocating it to a developer-only section to avoid confusing end users.🧰 Tools

188-188: Review: Verify the spelling of "knowlege".
The entry "knowlege" appears to be a potential misspelling of "knowledge." Please confirm if this spelling is intentional for domain-specific purposes or if it should be corrected.
192-192: Review: Confirm the term "Lockboxe".
"Lockboxe" may be a domain-specific term; however, if the intended word is "Lockbox," please update it to ensure consistency with related documentation (e.g., theLockboxSuperchainERC20contract).
321-321: Review: Evaluate duplicate entry "proxied".
The lowercase "proxied" on line 321 is added alongside an uppercase "Proxied" on line 320. If both case forms are required for proper vocabulary matching, consider adding a comment or note to clarify the intentional duplication.🧰 Tools

51-54: Step-by-Step Introduction
The introduction to the step-by-step guide is clear and differentiates between using Supersim and deploying to development networks.
55-66: Supersim Installation Instructions
The "Install and run Supersim" step is clearly explained with an appropriate command block. It might be useful to add a note that this command is intended for test deployments only.
68-76: ERC-20 Token Setup on Chain A
The instructions to download, set permissions, and run the setup script are straightforward. Verify that the URL for the setup script remains correct.
78-82: Development Networks Deployment
The alternative command for deploying to development networks is concise and clear. No issues detected.🧰 Tools

84-91: Storing Contract Addresses
The snippet for storing theBEACON_ADDRESSandERC20_ADDRESSis clear and follows standard shell practices.
113-118: Devnet Environment Variables
The Devnet tab provides clear instructions for setting environment variables using dynamic commands. This approach helps avoid hardcoding sensitive data.
135-143: Deployment Script Reference
The instruction to create the deployment script (script/LabSetup.s.sol) and its corresponding code block reference are well integrated into the tutorial. Confirm that the referenced file remains accessible in the repository.
144-149: Deploying on Chain B
The command for deploying contracts on chain B using Forge is straightforward and easy to follow.
288-293: Next Steps Section
The "Next steps" section effectively directs the reader to further actions, including deploying a SuperchainERC20 and exploring additional resources. This clear call-to-action helps guide the user’s next moves.

145-154: Use Imperative Tone for Instruction
The sentence “We create a Foundry project and import the OpenZeppelin contracts…” should be rephrased using the imperative form (e.g., “Create a Foundry project and import…”) to align with documentation best practices.Proposed Diff:

32-37: Casual Language in Warning Block
The warning callout (lines 32–37) uses a friendly tone (“You're welcome to use it…”). For consistency with professional documentation, consider using a more neutral phrasing such as “You may use this sample code; however, for production purposes it is advisable to have it audited first.”pages/stack/interop/tutorials/upgrade-to-superchain-erc20/lockbox.mdx (5)
18-20: Grammar Improvement: Add Missing Article and Adjust Noun Usage
The sentence “The lockbox is smart contract that accepts deposits…” is missing an article. Consider updating it to “The lockbox is a smart contract that accepts deposits of the original ERC-20 and issues an equivalent number of tokens…” for improved clarity and correctness.Proposed Diff:

The warning callout effectively communicates that the sample code has not been audited. For a more formal tone, consider rephrasing “you're welcome to use it” with an imperative directive.
27-33: Internal comment block review.
This comment block appears to be for internal guidance (e.g., use of “IMHO”). Before final publication, remove or refine internal notes to avoid exposing draft commentary to end users.Additionally, note the static analysis hint regarding the comma before “because” on line 29—ensure that punctuation serves the intended meaning if you decide to keep any internal notes.

7-7: Import statement is correct.
The import of{ Callout, Steps, Card, Cards }fromnextra/componentsis appropriate and aligns with the project’s component usage.
9-12: Callout component usage is appropriate.
The initial callout clearly informs users about the production readiness of the SuperchainERC20 standard.
14-14: H1 header formatting.
The H1 “Upgrading ERC20 to SuperchainERC20” is clear and sufficiently descriptive. Ensure consistency with naming conventions across the documentation.
16-19: Overview section clarity.
The overview section succinctly explains the upgrade process and includes well-integrated links to additional resources. Double-check that linked resources remain up-to-date.
35-36: Content clarity in upgrade options.
The introductory paragraph to the upgrade methods is clear. Verify that the instruction “click any of the green rectangles” accurately reflects the UI design so that users can easily identify these actionable elements.
37-47: Mermaid diagram structural review.
The Mermaid diagram neatly outlines the decision process involved in upgrading an ERC20 token. Ensure that all hyperlink URLs (e.g., for new contract deployment, lockbox, and proxy upgrade) correctly resolve in the deployed documentation.
50-53: Cards component structure.
The Cards component effectively presents the upgrade options with clear titles, links, and icons. Confirm that the icon paths (e.g.,/img/icons/shapes.svg) are correct within the project.
55-60: Next steps section clarity.
The bullet-pointed “Next steps” provide straightforward guidance for further actions. Ensure that all links (such as/deploy-superchain-erc20and/stack/interop/superchain-erc20) are accurate and that the language is consistent and directive throughout the documentation.

11-11: Import Statement Review
The import on line 11 includesCallout,Steps,Card, andCardsfromnextra/components. Note that theStepscomponent is not used in the remainder of the document. Consider removing it to keep the imports clean.- import { Callout, Steps, Card, Cards } from 'nextra/components' + import { Callout, Card, Cards } from 'nextra/components'
18-18: Header Naming Convention
The H1 header “Upgrading ERC20 to SuperchainERC20” is clear. Ensure that the use of “ERC20” (without the hyphen) is consistent throughout the documentation, as past reviews have noted inconsistencies in similar documents.
24-29: Warning Callout Tone
The warning callout clearly warns that the sample code is provided as-is and has not been fully audited. To maintain an impersonal tone, consider rephrasing “we ran it, and it works as advertised” to “The sample code has been executed and functions as intended.”

25-35: About This Tutorial Section
The “About this tutorial” segment is useful for setting expectations. However, the bullet point on line 30 contains awkward phrasing ("how to take permissionlessly create a lockbox contract"). Consider rephrasing this to “how to create a lockbox contract permissionlessly” for clarity.
107-116: Environment Variables Setup
The provided commands for setting environment variables (including the use of a test-private key) are detailed and correctly formatted. As with the proxy upgrade file, consider adding a note that these keys are for testing/demo purposes only.🧰 Tools

I like the idea behind it, but this doesn't work IMO. It's far too hard to parse if folks are just trying to figure out where to go.
We should either redo the diagram at a design level, or explore other way to funnel folks into the correct area
