Actionable comments posted: 31
🧹 Outside diff range and nitpick comments (21)
x/bank/v2/types/authorityMetadata.go (1)
7-15: LGTM: TheValidate()method is well-implemented.The
Validate()method correctly checks theAdminfield of theDenomAuthorityMetadatatype. It properly handles both empty and non-empty cases, and the error handling is correct. The implementation follows the Uber Go Style Guide by keeping the happy path on the left.A minor suggestion for improvement:
Consider adding a comment to explain the purpose of this validation, especially why an empty
Adminfield is considered valid. This would enhance the code's readability and maintainability.+// Validate checks if the Admin field is either empty or a valid Bech32 address. +// An empty Admin field is considered valid. func (metadata DenomAuthorityMetadata) Validate() error { // ... (rest of the function remains the same) }x/bank/v2/keeper/params.go (2)
9-12: Update the comment to match the method's functionality.The current comment doesn't accurately describe the
SetParamsmethod. Consider updating it to:// SetParams sets the parameters for the bank moduleThe method implementation looks good and correctly sets the parameters using
k.params.Set.
14-21: Update the comment and consider logging the error.
- The current comment doesn't accurately describe the
GetParamsmethod. Consider updating it to:// GetParams returns the current parameters for the bank module
- Consider logging the error before returning the default value. This can help with debugging in case of unexpected issues:
if err != nil { k.Logger(ctx).Error("failed to get params", "error", err) return types.Params{} }The overall implementation of the method looks good, retrieving the parameters and handling potential errors appropriately.
x/bank/proto/cosmos/bank/v2/authorityMetadata.proto (1)
9-17: LGTM: Well-definedDenomAuthorityMetadatamessage with room for future extensions.The
DenomAuthorityMetadatamessage is clearly defined and well-commented. The use ofgogoprotooptions for equality checks and YAML serialization is appropriate. Theadminfield correctly allows for an empty string to represent "no admin".For future consideration:
As the comment mentions planned extensions, consider adding areservedblock for future fields. This can help maintain backwards compatibility as the message evolves.Example:
message DenomAuthorityMetadata { // ... existing fields ... // Reserved for future use reserved 2 to 10; reserved "future_field1", "future_field2"; }x/bank/v2/types/errors.go (2)
3-3: Reconsider the use of// DONTCOVERcommentThe
// DONTCOVERcomment is typically used to exclude files from test coverage reports. However, for an errors file, it's generally beneficial to include it in coverage reports to ensure all error cases are properly tested.Consider removing this comment unless there's a specific reason for excluding this file from coverage reports.
11-19: Error definitions look good, with a minor suggestion for consistencyThe error definitions are well-structured and follow best practices:
- Each error has a unique code and descriptive message.
- The use of
errorsmod.Registeris correct for defining sentinel errors.- Error codes are sequential, which is good for maintainability.
For consistency, consider using
fmt.Sprintffor all error messages, even those without dynamic values. This would make future additions of dynamic content easier. For example:ErrDenomExists = errorsmod.Register(ModuleName, 2, fmt.Sprintf("attempting to create a denom that already exists (has bank metadata)")) ErrUnauthorized = errorsmod.Register(ModuleName, 3, fmt.Sprintf("unauthorized account")) ErrInvalidDenom = errorsmod.Register(ModuleName, 4, fmt.Sprintf("invalid denom")) ErrInvalidCreator = errorsmod.Register(ModuleName, 5, fmt.Sprintf("invalid creator"))x/bank/v2/types/keys.go (1)
35-37: LGTM! Consider adding comments for new prefixes.The new variables
DenomMetadataPrefixandDenomAuthorityPrefixare correctly implemented and follow the existing naming conventions and prefix numbering sequence. This is consistent with the Uber Golang style guide.To improve code documentation, consider adding brief comments explaining the purpose of these new prefixes, similar to the existing comments for other prefixes in this file.
+// DenomMetadataPrefix is the prefix for storing denomination metadata DenomMetadataPrefix = collections.NewPrefix(6) +// DenomAuthorityPrefix is the prefix for storing denomination authority information DenomAuthorityPrefix = collections.NewPrefix(7)x/bank/proto/cosmos/bank/v2/genesis.proto (3)
30-31: LGTM: New denom_metadata field is well-defined.The addition of the
denom_metadatafield to the GenesisState message is appropriate and well-structured. It allows for the inclusion of metadata for different coins in the genesis state.Consider adding a brief comment explaining the purpose and usage of this field, similar to the comments for other fields in the message. For example:
// denom_metadata defines the metadata of the different coins. repeated Metadata denom_metadata = 4 [(gogoproto.nullable) = false, (amino.dont_omitempty) = true];
33-33: LGTM: New factory_denoms field is well-defined.The addition of the
factory_denomsfield to the GenesisState message is appropriate and well-structured. It allows for the inclusion of token factory denominations in the genesis state.Consider adding a brief comment explaining the purpose and usage of this field, similar to the comments for other fields in the message. For example:
// factory_denoms defines the denominations created through the tokenfactory module. repeated GenesisDenom factory_denoms = 5 [(gogoproto.nullable) = false];
54-61: LGTM: New GenesisDenom message is well-defined.The addition of the GenesisDenom message is appropriate and well-structured. It provides a clear representation of token factory denominations in the genesis state.
Consider renaming the
authority_metadatafield toadmin_metadatafor consistency with theadminterminology used in other parts of the Cosmos SDK. This would make the field name more intuitive and aligned with the broader SDK conventions. For example:message GenesisDenom { option (gogoproto.equal) = true; string denom = 1; DenomAuthorityMetadata admin_metadata = 2 [(gogoproto.nullable) = false]; }x/bank/v2/module.go (1)
101-102: LGTM! Consider grouping related handlers together.The addition of
MsgCreateDenomandMsgChangeAdminhandlers is correct and follows the existing pattern. These new handlers align with the PR objectives of introducing functionalities for creating denominations.For better code organization, consider grouping related handlers together. For example:
appmodulev2.RegisterMsgHandler(router, handlers.MsgUpdateParams) appmodulev2.RegisterMsgHandler(router, handlers.MsgSend) appmodulev2.RegisterMsgHandler(router, handlers.MsgMint) appmodulev2.RegisterMsgHandler(router, handlers.MsgCreateDenom) appmodulev2.RegisterMsgHandler(router, handlers.MsgChangeAdmin)This grouping improves readability by keeping denomination-related handlers adjacent to each other.
x/bank/v2/types/params.go (2)
4-4: Remove unnecessary import alias forfmtpackage.The alias
fmt "fmt"is redundant since the package name is the same as the imported package. You can simplify the import statement to:import ( "fmt" // other imports )
18-18: Define a constant for the default gas consumption value.Using a constant for the default gas consumption improves readability and maintainability.
Example:
const DefaultDenomCreationGasConsume uint64 = 1_000_000 func DefaultParams() Params { return NewParams(sdk.NewCoins(), DefaultDenomCreationGasConsume) }x/bank/proto/cosmos/bank/v2/bank.proto (2)
16-18: Ensure consistent use of(gogoproto.nullable)optionFor the field
denom_creation_fee, you've set(gogoproto.nullable) = false, making it non-nullable. Please verify that this is intentional and consistent with how other fields are handled. Non-nullable fields generate more straightforward Go code without pointer references.
26-26: Consider setting(gogoproto.nullable)to false for scalar typesFor the field
denom_creation_gas_consume, you've set(gogoproto.nullable) = true. Sinceuint64is a scalar type, making it nullable will generate a pointer touint64in the Go code, which may not be necessary. For consistency and to simplify the generated code, consider setting(gogoproto.nullable) = false.x/bank/v2/keeper/createdenom.go (1)
59-60: Enhance TODO comment with actionable detailsThe TODO comment lacks a ticket reference or a clear description of the task. As per the Uber Go Style Guide, TODO comments should include a reference or a concise explanation of the work to be done.
Consider updating the TODO comment:
-// TODO: do we need map creator => denom +// TODO(#IssueNumber): Assess the necessity of mapping from creator to denom.Replace
#IssueNumberwith the relevant issue tracker number for better traceability.x/bank/proto/cosmos/bank/v2/tx.proto (2)
52-53: Add field comments for 'sender' and 'subdenom'.For clarity and better documentation, please add comments to the
senderandsubdenomfields explaining their purpose and any expected formats or constraints.
66-68: Add field comments for 'sender', 'denom', and 'new_admin'.Including descriptive comments for the
sender,denom, andnew_adminfields will enhance readability and assist developers in understanding the role and expected values of each field.x/bank/v2/keeper/handlers.go (2)
55-66: Add function documentation forMsgCreateDenomAccording to the Uber Go Style Guide, all exported functions should have a preceding comment that explains their purpose and usage. Please add a documentation comment for the
MsgCreateDenommethod to enhance code readability and maintainability.Example:
// MsgCreateDenom handles the creation of a new denomination.
68-68: Clarify the TODO comment regarding governanceThe TODO comment
// TODO: should be gov?suggests uncertainty about whether theMsgChangeAdminhandler should be managed through governance. Consider clarifying this decision to ensure the code aligns with the intended design. If this action should be moved to the governance module, I can assist with the refactoring process.Would you like help in integrating this functionality with the governance module or opening a GitHub issue to track this task?
x/bank/v2/keeper/keeper.go (1)
184-185: Update function comment forGetDenomMetaDatato follow Go conventionsThe comment for
GetDenomMetaDatashould start with the function name and be properly capitalized and punctuated to conform with Go standards.Consider updating the comment to:
// GetDenomMetaData retrieves the denomination metadata. It returns the metadata and true if the denom exists, false otherwise.

🛠️ Refactor suggestion
Validate that DenomCreationGasConsume is greater than zero.
Currently, validateDenomCreationGasConsume only checks the type of the parameter. To ensure meaningful values, consider validating that DenomCreationGasConsume is greater than zero.
You can add a check like:
value, _ := i.(uint64)
if value == 0 {
return fmt.Errorf("denom creation gas consume must be greater than zero")
}

🧹 Outside diff range and nitpick comments (21)
x/bank/v2/types/authorityMetadata.go (1)
7-15: LGTM: TheValidate()method is well-implemented.The method correctly validates the
Adminfield ofDenomAuthorityMetadatawhen it's not empty, using the SDK'sAccAddressFromBech32function. Error handling is appropriate, and the method returnsnilwhen there are no validation errors.Consider adding a comment to explain the purpose of this validation method, especially for other developers who might use this type. For example:
// Validate checks if the Admin field, if set, is a valid Bech32 address. // It returns an error if the Admin is set but invalid, otherwise nil. func (metadata DenomAuthorityMetadata) Validate() error { // ... (existing implementation) }x/bank/v2/keeper/params.go (2)

5-5: Remove unused importThe import
cosmos/base/v1beta1/coin.protois not used in this file. Consider removing it to keep the imports clean and avoid potential confusion.x/bank/v2/types/errors.go (2)
1-9: LGTM! Consider clarifying the DONTCOVER comment.The package declaration and imports look good. The
errorsmodimport with a custom path is correctly used.Consider adding a brief explanation for the
// DONTCOVERcomment, e.g.:// DONTCOVER - This file is excluded from test coverage reportsThis will help other developers understand why this file is excluded from coverage.
11-19: LGTM! Consider updating the module name in the comment.The error variable definitions look good. Each error has a unique code and a descriptive message, which is excellent for error handling and debugging.
The comment on line 11 mentions the "x/tokenfactory" module, but this file is in the "bank" module. Consider updating the comment to:
// x/bank module sentinel errorsThis will ensure consistency with the actual module name.
x/bank/v2/types/keys.go (1)
35-37: Consider adding comments for the new prefix variables.The new variables
DenomMetadataPrefixandDenomAuthorityPrefixare consistent with the existing naming conventions and initialization patterns. However, to improve code readability and maintainability, consider adding brief comments explaining the purpose of these prefixes, similar to the comments for other prefix variables in this file.Here's a suggested addition:
// DenomMetadataPrefix is the prefix for storing denomination metadata DenomMetadataPrefix = collections.NewPrefix(6) // DenomAuthorityPrefix is the prefix for storing denomination authority information DenomAuthorityPrefix = collections.NewPrefix(7)x/bank/v2/module.go (1)
101-102: LGTM! Consider grouping related handlers.The addition of
MsgCreateDenomandMsgChangeAdminhandlers is consistent with the existing pattern and adheres to the Uber Golang style guide.For improved readability and organization, consider grouping related handlers together. For example:
// Token-related handlers appmodulev2.RegisterMsgHandler(router, handlers.MsgMint) appmodulev2.RegisterMsgHandler(router, handlers.MsgCreateDenom) appmodulev2.RegisterMsgHandler(router, handlers.MsgChangeAdmin) // Transaction-related handlers appmodulev2.RegisterMsgHandler(router, handlers.MsgSend) // Admin-related handlers appmodulev2.RegisterMsgHandler(router, handlers.MsgUpdateParams)This grouping can make it easier to understand the different categories of handlers at a glance.
x/bank/v2/keeper/admins.go (2)
25-34: Add a comment to unexported function for clarityAlthough
setAdminis an unexported function, adding a brief comment explaining its purpose enhances code readability and maintenance.Consider adding a comment like:
// setAdmin updates the admin field in the authority metadata for a specific denom.
3-7: Group import statements according to Go conventionsThe import statements should be grouped with standard library packages separated from external packages by a blank line. According to the Uber Go Style Guide, this improves readability.
Apply this diff to group imports properly:
import ( "context" + "cosmossdk.io/x/bank/v2/types" )x/bank/v2/types/params.go (1)
3-7: Organize import statements according to style guidelinesPer the Uber Go Style Guide, import statements should be grouped into standard library packages, third-party packages, and then project packages, separated by blank lines. Ensure that imports are properly organized.
Apply this change:
import ( - fmt "fmt" - sdk "github.com/cosmos/cosmos-sdk/types" + "fmt" + sdk "github.com/cosmos/cosmos-sdk/types" )x/bank/proto/cosmos/bank/v2/genesis.proto (3)
33-33: Consider adding '(amino.dont_omitempty) = true' to 'factory_denoms'In the
GenesisStatemessage, other repeated fields likebalances,supply, anddenom_metadatahave the option(amino.dont_omitempty) = true. For consistency and to prevent omitting empty fields during amino encoding, consider adding(amino.dont_omitempty) = trueto thefactory_denomsfield.
54-56: Enhance documentation for 'GenesisDenom' to improve clarityThe current comment for
GenesisDenomcontains redundancy and could be clearer. Consider rephrasing it to:// GenesisDenom represents a token factory denomination included in the genesis // state. It contains DenomAuthorityMetadata, which defines the denom's admin.This revision eliminates redundancy and provides a clearer explanation.
61-61: Consider adding '(amino.dont_omitempty) = true' to 'authority_metadata'The field
authority_metadatainGenesisDenomis marked with[(gogoproto.nullable) = false]. For consistency with other non-nullable fields and to ensure proper amino encoding, consider adding(amino.dont_omitempty) = trueto this field's options.x/bank/v2/types/denoms.go (1)
53-55: Standardize error message formattingConsider rephrasing the error message to align with Go error handling conventions, which recommend starting messages with a lowercase letter and avoiding punctuation at the end.
Apply this diff to adjust the error message:
- return "", "", errors.Wrapf(ErrInvalidDenom, "denom prefix is incorrect. Is: %s. Should be: %s", strParts[0], ModuleDenomPrefix) + return "", "", errors.Wrapf(ErrInvalidDenom, "denom prefix is incorrect: expected %s, got %s", ModuleDenomPrefix, strParts[0])x/bank/proto/cosmos/bank/v2/bank.proto (1)
47-65: Ensure 'cosmos_proto.field_added_in' annotations are up-to-dateThe
Metadatamessage includes fields with the(cosmos_proto.field_added_in)annotation specifying versions like "cosmos-sdk 0.43" and "cosmos-sdk 0.46". Since this file is forcosmos.bank.v2, please confirm that these annotations accurately reflect when these fields were added relative to this module version.x/bank/v2/keeper/createdenom.go (1)
59-60: Address the TODO comment or create a tracking issueThere's a TODO comment at line 59 regarding the mapping from creator to denom. It's recommended to resolve TODOs or create GitHub issues to track them before merging.
Would you like me to open a GitHub issue to track this task?
x/bank/v2/keeper/handlers.go (2)
68-68: Consider handling admin changes via governanceThe comment
// TODO: should be gov?suggests that changing the admin of a denomination might be better managed through the governance module. Since changing the admin can have significant implications, routing this action through governance could ensure broader consensus and security.Would you like assistance in proposing a governance-based implementation for admin changes?
55-66: Wrap errors with contextual informationWhen returning errors, it's helpful to wrap them with additional context to aid in debugging and error tracing. This practice aligns with the Uber Go Style Guide's recommendations for error handling.
For example, in line 60~:
if err != nil { - return nil, err + return nil, fmt.Errorf("failed to create denom: %w", err) }This approach provides clarity on where and why the error occurred.
x/bank/v2/keeper/keeper.go (2)
31-32: Maintain consistent ordering of struct fieldsIn the
Keeperstruct, consider grouping related fields together for better readability. SincedenomMetadataanddenomAuthorityare related to denominations, they can be placed adjacent to other denomination-related fields.Adjust the struct field ordering:
type Keeper struct { appmodulev2.Environment authority []byte addressCodec address.Codec schema collections.Schema params collections.Item[types.Params] + denomMetadata collections.Map[string, types.Metadata] + denomAuthority collections.Map[string, types.DenomAuthorityMetadata] balances *collections.IndexedMap[collections.Pair[[]byte, string], math.Int, BalancesIndexes] supply collections.Map[string, math.Int] sendRestriction *sendRestriction }
187-188: Use consistent naming conventionsThe term "metadata" is used inconsistently in method names (
GetDenomMetaDatavs.denomMetadata). For clarity and consistency, consider using eitherMetaDataorMetadatathroughout.Rename the method to match the field name:
-func (k Keeper) GetDenomMetaData(ctx context.Context, denom string) (types.Metadata, error) { +func (k Keeper) GetDenomMetadata(ctx context.Context, denom string) (types.Metadata, error) {Apply similar changes to other methods and variables where applicable.

54-67:⚠️ Potential issueEnsure validation and uniqueness of factory denominations
While processing factory denominations, there is no explicit check for duplicate denominations or invalid entries. This could lead to issues during runtime if duplicates exist or if denominations are malformed.
Consider adding validation to ensure all factory denominations are unique and valid. You might also want to handle errors with more context.
for _, genDenom := range state.GetFactoryDenoms() { creator, _, err := types.DeconstructDenom(genDenom.GetDenom()) if err != nil { - return err + return fmt.Errorf("failed to deconstruct denom %s: %w", genDenom.GetDenom(), err) } err = k.createDenomAfterValidation(ctx, creator, genDenom.GetDenom()) if err != nil { - return err + return fmt.Errorf("failed to create denom %s: %w", genDenom.GetDenom(), err) } err = k.setAuthorityMetadata(ctx, genDenom.GetDenom(), genDenom.GetAuthorityMetadata()) if err != nil { - return err + return fmt.Errorf("failed to set authority metadata for denom %s: %w", genDenom.GetDenom(), err) } }Run the following script to check for duplicate factory denominations:

There was a problem hiding this comment.
🛠️ Refactor suggestion
Consider adding a validation rule for the admin address
The admin field is well-defined and commented. However, to ensure data integrity, consider adding a validation rule to check if the admin address is either empty or a valid osmosis address. This can be done using the validate.rules option from the protoc-gen-validate plugin.
Example:
string admin = 1 [
(gogoproto.moretags) = "yaml:\"admin\"",
(validate.rules).string = {
pattern: "^$|^osmo[a-zA-Z0-9]{39}$"
}
];This regex pattern allows either an empty string or a valid osmosis address.
Would you like me to provide more information on implementing this validation?

Avoid using panic in IterateAccountBalances
In the IterateAccountBalances method, calling panic when an error occurs is discouraged. Using panic can cause the entire application to crash, which is undesirable in production code.

I have some concerns about this feature. The original token factory was built for a permissioned chain which is always able to do this via migration code.
When a contract can use the TF to mint and burn tokens from any address, this opens the door to fraud.
The burn use-case is not new in other chains but what they do instead is providing transparency via metadata that the users know this is possible. See https://developers.stellar.org/docs/learn/encyclopedia/transactions-specialized/clawbacks for example

q: I noticed you are using bytes instead of an sdk address or string. This is not consistent with the auth, bank, gov and other modules. It can be a design decision though. I just want to check what is correct here?

This is good to have it byte, we want to avoid to have bech32 anywhere in a module. It is basically an sdk.AccAddress (which is a byte alias), but this forces use to the address codec to go to string.

nit: The Add method comes with some checks that ensure uniqueness and other constraints. Would it make sense to simply add the coins to a slice and cast and sort it later?

Panics are an anti pattern and may cause trouble begin/end-blockers when called. Instead the error should be returned so that the caller can decide on the appropriate action. Don't let the control flow loose.

No panic. See my comment above

personal preference: can this be a private method? There are no guards or functionality other than storing the data. It should not be used from outside the module in this state.

Would it make sense to let the caller define other metadata as well? I understand that there must be a trade-off between supported functionality and fraud prevention. Some code comment would be helpful, when this is limited for some reason.

The motivation the the xaccounts, I don't fully understand. I can see some benefit in using them but on the other hand, there can be rich contracts on chain that have their custom rulesets.
When you drop the constraint, the users can still decide on an the authority and don't have to pipe every operation through this proxy account. WDYT?

That long story about x/account 😅.
Before we just save the admin addr in state and keeper just compare if sender == admin to mint/burn (orginal Osmosis impl)
Then I moved that admin part the x/account layer to be compatible with the AssetInterface, which will also be implemented by x/account.
Rn me & @julienrbrt considering should we need x/account or not so this comment is nice TBD

AccAddressFromBech32 is deprecated. You can use the address codec instead

Avoid variable shadowing of err
At line 64, the declaration of err using := shadows the named return variable err. This can lead to confusion and potential bugs. Assign to the existing err variable instead.
Apply this diff to fix the variable shadowing:
- _, accountAddr, err := k.accountsKeeper.Init(ctx, admin.Type, creatorAddrBz, msgInitAdmin, sdk.NewCoins())
+ _, accountAddr, err = k.accountsKeeper.Init(ctx, admin.Type, creatorAddrBz, msgInitAdmin, sdk.NewCoins())📝 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.
