17-17: Consider moving the token address to environment variables.Hardcoding contract addresses makes the code less maintainable and harder to update for different environments.
-const tokenAddress = "0xF3Ce0794cB4Ef75A902e07e5D2b75E4D71495ee8" +const tokenAddress = process.env.TOKEN_ADDRESS as `0x${string}`🧰 Tools

17-17: Detected a Generic API Key, potentially exposing access to various services and sensitive operations.

18-32: Consider using a complete ERC20 ABI.The current ABI only includes the
balanceOffunction. Consider using a complete ERC20 ABI to enable interaction with other token functions if needed in the future.
36-50: Consider reducing code duplication in wallet client creation.The wallet client creation code is duplicated. Consider extracting this into a helper function.
+const createWallet = (chain: Chain) => + createWalletClient({ + chain, + transport: http(), + account + }).extend(publicActions) + .extend(publicActionsL2()) + .extend(walletActionsL2()) -const wallet0 = createWalletClient({ - chain: interopAlpha0, - transport: http(), - account -}).extend(publicActions) - .extend(publicActionsL2()) - .extend(walletActionsL2()) +const wallet0 = createWallet(interopAlpha0) -const wallet1 = createWalletClient({ - chain: interopAlpha1, - transport: http(), - account -}).extend(publicActions) - .extend(publicActionsL2()) - .extend(walletActionsL2()) +const wallet1 = createWallet(interopAlpha1)
65-75: Consider more robust number formatting.The current implementation uses a fixed padding of 20 characters, which might not handle very large numbers correctly. Consider using a more robust formatting solution.
- chain0: ${balance0.toString().padStart(20)} - chain1: ${balance1.toString().padStart(20)} + chain0: ${balance0.toString().replace(/\B(?=(\d{3})+(?!\d))/g, ",")} + chain1: ${balance1.toString().replace(/\B(?=(\d{3})+(?!\d))/g, ",")}
79-84: Consider parameterizing the transfer amount.The transfer amount is hardcoded. Consider accepting it as a parameter or environment variable for flexibility.
- amount: 1000000000, + amount: BigInt(process.env.TRANSFER_AMOUNT || "1000000000"),pages/stack/interop/tutorials/transfer-superchainERC20.mdx (3)
25-26: Consider using a Callout component for the warning.The warning about irreversible transfers should be more prominent. Consider using the Callout component with type="warning".
-**Warning:** Always verify your addresses and amounts before sending transactions. -Cross-chain transfers cannot be reversed. +<Callout type="warning"> + Always verify your addresses and amounts before sending transactions. + Cross-chain transfers cannot be reversed. +</Callout>
57-61: Specify version requirements for all tools.The prerequisites section should include minimum version requirements for all tools to ensure compatibility.

2-2: Document metadata title updated.
The front-matter title is now “Transferring SuperchainERC20 tokens,” which aligns with the updated description. Please ensure that the main header (currently on line 14) is also updated for consistency.
27-28: Warning message is clear.
The cautionary note about verifying addresses and amounts appears concise and useful.
84-87: Review API key placeholder usage.
The shell block setting thePRIVATE_KEY(lines 84–87) uses a placeholder (0x<private key here>). Ensure that no actual API or private keys are committed and that developers are directed to secure key management practices.
147-168: Package configuration appears correct.
The modifications topackage.json—including the addition of thestartscript and dependencies—are accurate and follow best practices.

69-69: Compound adjective clarification.
Consider using “on‑chain” instead of “onchain” for clarity and consistency with industry terminology.
128-129: Refine instructional tone.
Replace phrases like “We are going to use” and “We use” with imperative or declarative language (e.g., “Initialize a Node project” and “Use TypeScript”) to maintain a neutral, instructional tone.
168-169: Correct code block language identifier.
The code block for creatingsrc/xfer-erc20.mtsis labeled as “solidity” even though the file’s.mtsextension indicates it contains TypeScript. Update the language identifier to “typescript” (or “tsx”, if appropriate) to ensure accurate syntax highlighting.

2-2: Header title update.
The front matter now clearly states the title as "Transferring SuperchainERC20 tokens," which aligns with the revised focus on token transfers. Please ensure that this naming is consistent with related metadata (for example, in_meta.json).
14-14: Header formatting consistency.
The header "# Transferring SuperchainERC20 tokens" now uses sentence case appropriately. Please double-check that the capitalization of the technical term “SuperchainERC20” adheres to the project’s naming conventions.
16-16: Introduction clarity.
The introductory sentence clearly states that the guide demonstrates programmatic transfer of SuperchainERC20 tokens. Ensure that the terminology (“SuperchainERC20 tokens”) remains consistent throughout the documentation.
18-23: Enhanced callout with instructions.
The new callout provides a concise overview and useful links (such as the explainer and sample UI) to guide users through the token transfer process. Please verify that the linked resources are up to date.
27-28: Warning message emphasis.
The warning to verify addresses and amounts before sending transactions is well placed to prevent irreversible errors during cross-chain transfers.
30-33: Overview of build objectives.
The sections "What you'll build" and "What you'll learn" clearly outline the project goals and learning outcomes. Ensure that these headings follow sentence case conventions as required by the documentation guidelines.
39-48: Prerequisites detail.
The "Prerequisites" section is comprehensive and lists the required technical knowledge and skills. Verify that the capitalization of terms (e.g., TypeScript, smart contract development) aligns with the project's style guide and the nouns specified innouns.txt.
72-78: Environment variable setup.
The instructions for creating environment variables with the RPC endpoints and token address are explicit and easy to follow.🧰 Tools

The token address (TOKEN_ADDRESS=0xF3Ce0794cB4Ef75A902e07e5D2b75E4D71495ee8) is hard-coded in the instructions. Although this is likely intended as a public example, please verify that it does not inadvertently expose sensitive data or trigger security warnings (such as generic API key detections).🧰 Tools

87-92: Transaction submission clarity.
The shell commands provided for sending ETH to the two L2 blockchains are straightforward. Ensure that the RPC URLs and transaction values are appropriate for a testnet environment and that users understand these commands are for demonstration purposes only.
94-104: Delay and sanity check instructions.
The step advising users to wait for ETH to appear on the block explorer, accompanied by a sanity check block, is well structured and helps confirm transaction success.
105-125: Token acquisition steps.
The guidance for obtaining tokens—both via the block explorer and using thecastfaucet command—is detailed and user-friendly. Verify if any rate limits or prerequisites should be mentioned to prevent confusion.
126-130: Transition to TypeScript.
This section effectively explains the shift to a Node project and the utilization of [@eth-optimism/viem] for transferring tokens. The rationale for using TypeScript for enhanced type safety is clearly stated.
131-139: Node project initialization.
The commands for setting up a new Node project (including directory creation and dependency installation) are accurate and easy for users to follow.
141-165: Package configuration update.
The modifications topackage.json, particularly adding thestartscript and specifying dependency versions, are clear. It is advisable to double-check that the dependency versions (e.g., for viem and tsx) are compatible and maintained.
166-170: TypeScript script creation.
The instructions to create thesrc/xfer-erc20.mtsfile are straightforward. Ensure that the file reference (<rootDir>/public/tutorials/xfer-erc20.mts) is accurate and that any associated hashes remain valid as the code evolves.
171-197: Detailed explanation block.
The expandable<details>section provides valuable context regarding the internals of the token transfer (including function calls and transaction relay details). Please verify that the code references (hashes and line numbers) stay current with future updates.
198-203: Execution instructions confirmation.
The final step instructing users to run the TypeScript program withnpm startis clear. Consider advising users on troubleshooting steps if the token balance changes do not appear as expected.
207-212: Next steps and resource links.
The "Next steps" section effectively directs users to additional resources (explainer, design video, further reading, and Supersim). Confirm that all external links and resource descriptions are current and that the language remains clear and consistent with the documentation standards.

1-22: Frontmatter completeness and consistency.
The frontmatter includes all required keys (title,description,lang,content_type,topic,personas, andcategories). As a good-to-have improvement, consider standardizing the case and style of thetopicfield—for example, using a similar phrasing to the title (e.g. "Transferring SuperchainERC20 Tokens") if that better aligns with your naming conventions.
21-21: Data type suggestion for metadata.
The fieldis_imported_contentis set to the string'false'. If type consistency is important, consider using a boolean value (i.e.false) instead.
146-150: Avoid first-person pronouns in instructional tone.
Lines 148–149 use “We are going to use…” and “We use…”. To align with documentation best practices, consider rephrasing these lines in the imperative mood (e.g. “Use a Node project to leverage…” and “Utilize TypeScript for type safety…”) to maintain a neutral, instructive tone.
161-184: Package.json improvements.
While the package.json snippet is well structured, the"description"field is empty. Providing a meaningful description—even a short one—could improve project clarity for developers examining the project.
