9-11: Consider handling the error gracefully.Panicking on error is not the best practice for a production-grade application. Instead of panicking, consider handling the error gracefully. For example:
err := chainclient.DownloadOfacList() if err != nil { log.Printf("Failed to download OFAC list: %v", err) return }client/metadata/ofac.json (1)
4-5: Clean up the duplicate Ethereum addresses.There are a few duplicate Ethereum addresses in the list:

1-12: LGTM!The code provides a clear and concise example of how to use the new
DownloadOfacListfunction from thechainclientpackage to download the OFAC list.client/chain/ofac.go (4)
27-40: LGTM!The function correctly initializes the
OfacCheckerby ensuring the OFAC list is available locally and loaded into memory. It handles errors appropriately.
50-76: LGTM!The function correctly downloads the OFAC list from the specified URL and saves it locally. It handles errors appropriately.
78-93: LGTM!The method correctly loads the OFAC list from the local file into memory for efficient lookups. It handles errors appropriately.
95-97: LGTM!The method provides a simple and efficient way to check if an address is blacklisted by leveraging the map data structure for fast lookups.
client/metadata/ofac.json (1)
1-48: LGTM! The file structure and content are valid.The
client/metadata/ofac.jsonfile contains a valid JSON array of Ethereum addresses. This file serves as a reference for the application to check against when determining whether a transaction or interaction involves an entity sanctioned by the Office of Foreign Assets Control (OFAC).Ensure that this list is kept up to date with the latest OFAC regulations to maintain compliance.
client/chain/chain_test.go (1)
58-122: LGTM!The
OfacTestSuiteis a well-structured test suite that thoroughly tests the OFAC list functionality. The setup and teardown methods effectively manage the test environment, and theTestOfacListmethod correctly verifies the expected behavior when the OFAC list is present.The use of the
testify/suitepackage enhances the organization and error handling of the tests.client/chain/chain.go (2)
324-325: LGTM!The addition of the
ofacCheckerfield to thechainClientstruct is a valid change. It enables the client to perform OFAC compliance checks.
445-458: LGTM!The code segment correctly initializes the
OfacCheckerand performs the OFAC compliance check during client initialization. If the account's address is blacklisted, the client initialization fails with an appropriate error message.

Consider improving the OFAC list path determination.
The current implementation assumes a specific directory structure and may break if the structure changes. It also doesn't handle the case where the "sdk-go" directory is not found.
Consider the following improvements:
- Use a configuration file or environment variable to specify the OFAC list path instead of relying on a specific directory structure. This would make the code more flexible and easier to maintain.
- Handle the case where the "sdk-go" directory is not found by returning an error or using a default path. This would make the code more robust and prevent potential issues.

Consider returning an error instead of panicking.
The OFAC compliance check on the granter address is correctly performed. However, as mentioned in the previous comments, using panic is generally discouraged. It would be better to return an error instead of panicking to allow proper error handling.
Apply this diff to return an error instead of panicking:
- if c.ofacChecker.IsBlacklisted(granter) {
- panic("Address is in the OFAC list") // panics should generally be avoided, but otherwise function signature should be changed
- }
+ if c.ofacChecker.IsBlacklisted(granter) {
+ return nil, errors.New("granter address is in the OFAC list")
+ }Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Consider returning an error instead of panicking.
The OFAC compliance check on the granter address is correctly performed. However, using panic is generally discouraged as it abruptly terminates the program. It would be better to return an error instead of panicking to allow proper error handling.

- if c.ofacChecker.IsBlacklisted(granter) {
