🧹 Nitpick comments (37)
packages/rs-sdk/src/platform/transition/fungible_tokens/emergency.rs (3)
19-19: Clarify the doc comment to accurately reflect the emergency context rather than minting tokens.Currently, the doc comment says "A builder to configure minting tokens," but this code handles emergency actions.
-/// A builder to configure minting tokens. +/// A builder to configure emergency token actions.
38-39: Implement the token position validation to address the TODO.The
TODOcomment indicates that token position validation is pending. This is important to ensure the correct token contract position is used during the pause operation.Do you want me to propose code for performing this validation and open a new issue to track it?
84-85: Offer to handle automatic group info resolution.The
TODOmentions simplifying group actions by automatically finding the token position if a group action is required. Handling this logic within a helper function or the builder itself may reduce duplication and minimize user error.packages/wasm-dpp/src/document/state_transition/batch_transition/token_transition/mod.rs (1)
93-114: Consider avoiding unnecessary cloning in the match arms.Cloning large data structures in each branch may incur performance overhead. Where possible, pass references or clone lazily (only when needed).
packages/rs-sdk/src/platform/transition/fungible_tokens/unfreeze.rs (3)
18-18: Update the struct-level documentation.The doc comment says “A builder to configure minting tokens,” but this structure is for unfreezing tokens.
-/// A builder to configure minting tokens. +/// A builder to configure unfreezing tokens.
38-38: Address the TODO to validate token position.This is critical to prevent invalid token positions from being used, which could lead to logic errors downstream.
Do you want me to generate a helper function or open a new issue to track and implement the validation step?
75-117: Add error handling for broadcast failures.Currently, the code logs the error (by using
?), but consider adding a retry mechanism or more specific error details in certain scenarios (e.g., insufficient fees, invalid token state).packages/dapi/lib/externalApis/drive/fetchProofForStateTransitionFactory.js (2)
17-17: Document the newdppparameter.Ensure function-level JSDoc or inline documentation clarifies the usage of
dpp.
133-145: Provide consistent error messages.In case of an unsupported transition type, the error message is helpful. Ensure uniform error reporting format across all batched transition checks.
packages/wasm-dpp/src/data_contract/tokens.rs (2)
1-3: Consider adding documentation comments.These imports and the bridging logic could benefit from Rust doc comments (e.g.,
///) explaining how this Wasm-bound wrapper should be used from JavaScript.
14-18: Prefer implementingFrom<TokenConfigurationWasm>forTokenConfiguration.In Rust,
Into<T>is automatically derived ifFrom<U> for Tis implemented. Hence, it’s often more idiomatic to implement onlyFrom<TokenConfigurationWasm>forTokenConfigurationand omitInto(TokenConfiguration).-impl Into<TokenConfiguration> for TokenConfigurationWasm { - fn into(self) -> TokenConfiguration { - self.0 - } -} +impl From<TokenConfigurationWasm> for TokenConfiguration { + fn from(value: TokenConfigurationWasm) -> Self { + value.0 + } +}packages/wasm-dpp/src/document/state_transition/batch_transition/token_transition/freeze.rs (1)
16-22: Add documentation to clarify usage.Adding a doc comment or short description explaining what
getFrozenIdentityIddoes can help JavaScript consumers quickly understand the method’s purpose.packages/wasm-dpp/src/document/state_transition/batch_transition/token_transition/transfer.rs (1)
16-22: Enhance clarity with doc comments.Providing a short doc comment for
getRecipientIdcan guide JS developers on what the method returns and how to properly use it.packages/wasm-dpp/src/document/state_transition/batch_transition/token_transition/unfreeze.rs (1)
16-22: Add doc comments for clarity.A short Rust doc comment elaborating on the purpose of
getFrozenIdentityIdwould be beneficial, ensuring developers have immediate context in the generated TypeScript definitions.packages/wasm-dpp/src/document/state_transition/batch_transition/token_transition/destory.rs (1)
1-5: Typo in the filename
The file name is spelled "destory.rs" instead of "destroy.rs". Please rename the file to maintain clarity and consistency.- packages/wasm-dpp/src/document/state_transition/batch_transition/token_transition/destory.rs + packages/wasm-dpp/src/document/state_transition/batch_transition/token_transition/destroy.rspackages/rs-sdk/src/platform/transition/fungible_tokens/burn.rs (4)
1-17: Ensure consistent error handling & logging imports
The list of imports looks good, covering necessary traits and modules. However, consider adding a common logging crate if you plan to emit logs or debug information during the burn operation. This helps with observability if errors occur downstream and might simplify debugging.
18-28: Clarify docstring forBurnTokensBuilder
The docstring states "A builder to configure and broadcast burning tokens transition," which is clear. For completeness, consider adding a high-level usage example or any prerequisites (like verifying the caller’s identity) to guide new developers.
30-49: Address theTODOcomment for validating token position
You have aTODO(line 37) to validate the token position. This is critical to avoid scenarios where invalid positions cause runtime failures or security issues.Would you like me to generate a quick helper function that checks valid positions for you?
61-67: Resolve theTODOregarding group info
Similar to the earlier validation TODO, the note here implies automatically detecting position if group action is required. This might significantly reduce boilerplate for clients.Let me know if you need a prototype or a separate utility function to streamline group logic.
packages/rs-sdk/src/platform/transition/fungible_tokens/destroy.rs (2)
29-49: Graceful error handling around token position
You have anotherTODO(line 37) to validate token position. Ensure consistent logic across the entire token-lifecycle code, so invalid positions fail early with a clear error.
61-67: Group info comment
Again, a TODO suggests potential automation. You might consider a shared helper used by bothBurnTokensBuilderandDestroyFrozenTokensBuilderif the logic overlaps.packages/rs-sdk/src/platform/transition/fungible_tokens/freeze.rs (3)
30-49: Add token position checks
As with the other transitions, line 38 has a TODO for validating the token position. Addressing this helps avoid passing invalid configuration values.
61-67: Group info
Similar suggestion: a shared helper to auto-detect group usage is a good practice.
119-132: Mention side effects in doc
When tokens are frozen, consider indicating the side effects left on downstream states, so callers know the impact. Otherwise, the code is well-structured.packages/rs-sdk/src/platform/transition/fungible_tokens/mint.rs (4)
18-29: Confirm default values and add field-level documentation.
While the struct is clearly defined, consider documenting each field's intended usage, especially for optional fields likepublic_noteandsettings, to guide other developers.
54-60: Clarify the conditions for destination issuance.
The TODO at line 57 notesminting_allow_choosing_destination. Ensure the final builder logic aligns with the contract’s constraints regarding recipient IDs.
72-78: Simplify group actions logic.
The TODO at line 75 suggests automatically determining the token position if group actions are required. This can reduce complexity for callers.
85-129: Consider advanced error handling and a final check.
Upon constructing the state transition, consider verifying any last-minute constraints (e.g., max token supply or contract-limited minting) to fail early if the request is invalid.packages/rs-sdk/src/platform/transition/fungible_tokens/transfer.rs (4)
21-34: Update the doc comment to match “Transfer” context.
Line 36 refers to “Start building a mint tokens request.” Change it to reflect token transfers for clarity.- /// Start building a mint tokens request for the provided DataContract. + /// Start building a token transfer request for the provided DataContract.
60-66: Encourage encryption usage checks.
with_shared_encrypted_noteis optional. If certain contract rules mandate encryption, consider adding a warning or a built-in safeguard.
92-136: Strengthen transfer constraints.
When doing a token transfer, confirm that the sender has sufficient balance or ownership. Ensure the logic calls or enforces checks to avoid partial or failing transitions down the line.
138-151: Document usage of the returned BTreeMap.
broadcast_and_wait_for_resultreturns a map of identifiers to token amounts. Provide guidance or doc comments on how to interpret multiple recipients if relevant.packages/rs-dpp/src/state_transition/state_transitions/document/batch_transition/batched_transition/token_transfer_transition/v0/v0_methods.rs (2)
48-54: Add doc references to structured note types.
Now thatshared_encrypted_noteis anOption<&SharedEncryptedNote>, consider referencing the new type’s docs to help other developers.
132-140: Document usage of “as_ref” vs. owned calls.
Line 136 ensures an owned return for the shared note, while 132 returns a reference. Clarify guidelines on when to consume vs. borrow.packages/rs-drive/src/state_transition_action/batch/batched_transition/token_transition/token_transfer_transition_action/v0/mod.rs (1)
91-97: Encourage additional docstrings.
For these note-related methods, docstrings clarifying how these notes are encrypted or used in transitions help maintain code clarity.packages/rs-dpp/src/tokens/token_event.rs (1)
18-24: Consistent use of strongly typedSharedEncryptedNoteSwitching from raw tuples to a strongly typed
SharedEncryptedNoteenhances maintainability. Consider extending this approach toTokenEventPersonalEncryptedNotefor a uniform, strongly typed codebase.packages/wasm-dpp/src/document/state_transition/batch_transition/mod.rs (1)
111-115: Consider improving variable naming within thematcharms for clarity.
The variablesdocinToken(doc)andtokinDocument(tok)can cause confusion due to the mismatch in naming. Renaming them totoken_transitionanddocument_transitionor similar will make the code more readable.match tr.to_owned_transition() { - BatchedTransition::Token(doc) => TokenTransitionWasm::from(doc).into(), - BatchedTransition::Document(tok) => DocumentTransitionWasm::from(tok).into(), + BatchedTransition::Token(token_transition) => TokenTransitionWasm::from(token_transition).into(), + BatchedTransition::Document(document_transition) => DocumentTransitionWasm::from(document_transition).into(), }

TokenEmergencyActionTransitionwith WASM code.
4-6: Emergency action wrapper is clearly structuredThe annotation and struct definition follow the established pattern, ensuring consistency in emergency action handling.
8-12: Seamless conversionUsing
Fromensures straightforward interoperability with consumers expecting the WASM wrapper.packages/wasm-dpp/src/data_contract/tokens.rs (1)
4-7: Struct naming alignment.Wrapping the underlying
TokenConfigurationin a tuple struct namedTokenConfigurationWasmis consistent with typical Wasm-bound patterns. Good job on maintaining naming clarity and ensuring it’s discoverable as an exported entity for JavaScript.packages/wasm-dpp/src/document/state_transition/batch_transition/token_transition/freeze.rs (2)
6-8: Wrapper struct naming is consistent and clear.This tuple struct pattern nicely reflects the underlying
TokenFreezeTransitionand ensures minimal overhead while bridging to JS.
10-14: Conversion trait implementation is consistent.You provide a straightforward
From<TokenFreezeTransition>implementation, which is concise and idiomatic for data bridging.packages/wasm-dpp/src/document/state_transition/batch_transition/token_transition/transfer.rs (2)
6-8: Struct definition is aligned with best practices.This pattern is consistent with other token transition WASM wrappers. The design fosters a straightforward integration of Rust and JavaScript code.
10-14: Conversion approach reaffirms consistency.The
From<TokenTransferTransition>implementation parallels the freeze transition pattern, making the codebase uniform and easier to maintain.packages/wasm-dpp/src/document/state_transition/batch_transition/token_transition/unfreeze.rs (2)

The suffixWasmon the struct highlights that it is a WebAssembly wrapper. This naming pattern appears consistent with the rest of the codebase.
10-14: From trait usage
ImplementingFrom<TokenDestroyFrozenFundsTransition>is a straightforward way to safely wrap the underlying struct. No issues here.
16-22: Getter method
The methodfrozen_identity_idexposes the internal ID as expected and is properly annotated for JavaScript (js_name=getFrozenIdentityId). This looks good.packages/wasm-dpp/src/document/state_transition/batch_transition/token_transition/mint.rs (4)
1-8: Use ofWithJsError
The import ofWithJsErrorsuggests you're consistently handling Rust errors in a JavaScript-friendly manner. This is a good practice for bridging the two environments.
9-11: New struct for Wasm bridging
DefiningTokenMintTransitionWasmwith the#[wasm_bindgen(js_name=TokenMintTransition)]attribute properly exposes the struct to JavaScript.
13-17: Conversion trait
Usingimpl From<TokenMintTransition>ensures an ergonomic way to create the Wasm wrapper. No concerns.
19-31: Signature requiringTokenConfigurationWasm
pub fn recipient_id(&self, token_configuration: TokenConfigurationWasm) -> Result<IdentifierWrapper, JsValue>suggests the recipient ID depends on the provided token configuration. Verify that passing a configuration here is necessary instead of using internal struct data, especially if multiple transitions or different states might need distinct configurations.packages/rs-dpp/src/state_transition/state_transitions/document/batch_transition/batched_transition/token_transfer_transition/v0/mod.rs (3)
15-20: New type aliases for encrypted notes
DefiningSharedEncryptedNoteandPrivateEncryptedNoteclarifies the meaning of the tuple fields, improving readability and maintainability.
63-63:shared_encrypted_notefield
UsingOption<SharedEncryptedNote>aligns with the new type alias, reducing ambiguity and clarifying the intent of the note.
69-69:private_encrypted_notefield
Similarly, switching toOption<PrivateEncryptedNote>makes it clearer that this note is distinct from the shared one, and is not always present.packages/rs-drive/src/state_transition_action/batch/batched_transition/token_transition/token_transfer_transition_action/mod.rs (7)
6-6: Referencing new note aliases
ImportingSharedEncryptedNoteandPrivateEncryptedNoteensures code consistency across modules.
65-65:shared_encrypted_notegetter
ReturningOption<&SharedEncryptedNote>is appropriate for safe, read-only access to a potentially absent value.
71-71:shared_encrypted_note_ownedmethod
Providing an owned version of the note is valuable for scenarios where a consuming function needs full ownership.
77-77:set_shared_encrypted_notemethod
Accepting anOption<SharedEncryptedNote>enforces flexibility in either storing a new note or clearing the field ifNoneis provided.
109-109: Setter for private note
Consistently adopting the same pattern as withshared_encrypted_noteensures a uniform API for setting optional data.
121-122:notes()method return value
Exposing the collected optional notes in a tuple helps to retrieve all note-related data together, which can simplify external usage.
133-134:notes_owned()method return value
Similarly returning owned data for all notes is convenient for cases where external code needs to consume or modify them independently.packages/rs-sdk/src/platform/transition/fungible_tokens/burn.rs (4)
51-59: Fluent builder pattern is well-implemented
These methods follow the standard Rust builder pattern, ensuring optional fields are handled gracefully. Looks good!
69-72: Settings integration
Using an optionalPutSettingsis an elegant approach. The code is consistent with the rest of the builder pattern.
74-116: Confirmuser_fee_increaseusage
The method appliesunwrap_or_default()for user fee increases (line 105). Verify that default values align with chain or contract policy. Also, consider logging the final user fee if dynamic fees can affect user balances significantly.
118-131: Clean pattern for awaiting response
broadcast_and_wait_for_resultis straightforward and consistent with the rest of the codebase. Good job providing a succinct, chained flow for finalizing the operation.packages/rs-sdk/src/platform/transition/fungible_tokens/destroy.rs (5)
17-27: Confirm naming alignment
The struct is calledDestroyFrozenTokensBuilder, which is descriptive. Confirm that all calls to this builder are similarly named for consistency, e.g., “destroy_frozen_tokens”.
51-59: Good approach for optional fields
Having builder methods likewith_public_noteclarifies the code. No issues spotted here.
69-72: OptionalPutSettings
Same pattern as the burn builder: simple and effective.
74-116: Check broadcast flow for partial success
Unlike minting or burning, destroying frozen tokens might need special attention to partial or multi-step transitions in complex scenarios. Ensure no partial states are left if an error occurs after some tokens are destroyed.
118-131: Asynchronous response handling
broadcast_and_wait_for_resultis consistent with the approach from other token transition builders. This uniformity eases maintenance.packages/rs-sdk/src/platform/transition/fungible_tokens/freeze.rs (4)
18-28: Builder struct naming is correct
FreezeTokensBuilderaligns well with the file’s purpose, contrasting with the doc comment mismatch above.
51-59: Optional note & user fee
No issues here. The builder pattern is consistent.
69-72: Optional settings
Same usage as in other modules. Continues the consistent approach for optional fields.
75-117: Check error propagation
Thebroadcastmethod callsBatchTransition::new_token_freeze_transition(...)and then broadcasts. Confirm all?error paths clearly indicate context (e.g., “failed to freeze tokens”). Logging or wrapping the error helps.packages/rs-dpp/src/state_transition/state_transitions/document/batch_transition/batched_transition/token_transfer_transition/v0_methods.rs (6)
7-7: Using more expressive type aliases
Refactoring the previously used tuple intoSharedEncryptedNoteis a good improvement in readability and maintainability.
79-84: Check for version mismatches
When returningOption<&SharedEncryptedNote>, ensure that any new note version changes do not cause round-trip serialization issues.
85-90: Ownership approach
shared_encrypted_note_ownedreturningOption<SharedEncryptedNote>cleanly transfers ownership. This pattern is consistent with Rust best practices.
91-91: Consistent setter
set_shared_encrypted_notealigns well with the new typed approach.
121-121: Replace private tuple withPrivateEncryptedNote
Good job standardizing the private note approach, just like the shared note.
132-133: Consistent use of typed notes
ReturningOption<SharedEncryptedNote>andOption<PrivateEncryptedNote>innotes_ownedis a logical extension of your typed note approach. No major issues here.packages/rs-sdk/src/platform/transition/fungible_tokens/mint.rs (2)
1-17: Ensure imports are used consistently and cautiously.
All imports appear relevant to state transitions, resulting objects, and errors.
130-143: Validate broadcast result usage.
Ensure consumers ofbroadcast_and_wait_for_resulthandle the tuple(Identifier, TokenAmount)correctly, especially evaluating success/failure states.packages/rs-sdk/src/platform/transition/fungible_tokens/transfer.rs (1)
1-20: Confirm all imports are utilized and secure.
These imports are standard for bridging transitions and token ID calculations. No issues found.packages/rs-dpp/src/state_transition/state_transitions/document/batch_transition/batched_transition/token_transfer_transition/v0/v0_methods.rs (3)
6-6: Unified note type usage.
Replacing tuples with structured types (SharedEncryptedNote,PrivateEncryptedNote) improves readability and maintainability.
75-75: Check consistency of encrypted note usage.
If the private note is now also a structured type, ensure upstream or downstream code has aligned usage.Also applies to: 82-83
164-164: Validate partial or missing note states.
When “notes_owned” or “notes” omit one or more notes, confirm if partial encryption fields can cause confusion or errors.Also applies to: 172-173
packages/rs-drive/src/state_transition_action/batch/batched_transition/token_transition/token_transfer_transition_action/v0/mod.rs (3)
10-10: Approve type usage for shared/private notes.
UsingSharedEncryptedNoteandPrivateEncryptedNotefosters clarity.
118-118: Ensure optional fields remain in sync.
Whenshared_encrypted_noteis updated, confirm no mismatch with private note usage.Also applies to: 125-126, 133-134
167-175: Verify null states for notes.
Wherenotes()andnotes_owned()handleNonefields, ensure downstream logic handles partially absent notes gracefully.Also applies to: 199-199, 207-208, 221-222
packages/rs-dpp/src/state_transition/state_transitions/document/batch_transition/methods/v1/mod.rs (2)
17-19: Well-structured approach for typed encryption note usageReplacing the raw tuple-based approach for shared & private notes with dedicated types is a significant improvement in both clarity and maintainability. Great job streamlining these imports.
82-83: Improved function signature readabilityThis new signature is more intuitive thanks to
SharedEncryptedNoteandPrivateEncryptedNote. Just ensure all call sites pass the correct structure and that older tuple-based usage is updated accordingly.packages/rs-dpp/src/data_contract/mod.rs (1)
53-53: Publicly exposingTokenConfigurationMaking
TokenConfigurationpublic is justified to enable broader usage across the codebase. Confirm the interface is stable and well-documented to safeguard external consumers from unexpected changes.packages/wasm-dpp/src/data_contract/data_contract.rs (4)
10-10: ImportingTokenContractPositionfor modular token managementEnabling this import for referencing token configurations is aligned with the new feature set. Looks good for maintainability.
14-14: UtilizingDataContractV1GettersAdding
DataContractV1Gettersis a positive step, ensuring a clearer, type-safe interface for the WASM environment. Nicely done.
454-464: Newtoken_configurationmethodThis method cleanly exposes token configuration to external consumers under WASM. Consider adding tests for edge cases, such as an invalid or missing
token_contract_position.
26-26: Import ofTokenConfigurationWasmPlease confirm there are no naming collisions or overshadowed symbols across the crate. Usage looks straightforward, but verifying references helps ensure consistency.

🛠️ Refactor suggestion
Likewise, add missing token position validation for the resume flow.
Similar to the pause operation, the resume operation also includes a TODO for token position validation.
// Example: you can unify pause/resume validation in a helper method
fn validate_token_position(token_position: TokenContractPosition) -> Result<(), Error> {
// implement the checks you need here
}
...
// usage inside resume
Self {
data_contract,
token_position: {
validate_token_position(token_position)?;
token_position
},
...

Fix the import path to reflect the corrected module name.
Ensure that the destory reference aligns with the corrected spelling.

Correct the spelling in the module name.
The filename and references use destory instead of destroy. This inconsistency can cause confusion and maintenance difficulties.

🛠️ Refactor suggestion
Cache or reuse data contract retrieval results.
When multiple transitions share the same data contract, repeatedly querying and creating a data contract object may be expensive. Consider caching it to improve performance.

🛠️ Refactor suggestion
Validate token position prior to building.
A TODO at line 39 indicates missing validation logic. Consider adding checks for valid token positions, especially if out-of-range or negative values would cause downstream errors.

Validate token position.
Similar to MintTokensBuilder, the TODO at line 44 references missing position validation. Consider adding checks to prevent invalid positions from proceeding.

🛠️ Refactor suggestion
Double-check the combination of advanced note fields.
The struct redefines private_encrypted_note in a partial format. Consider updating it to be fully consistent with the new type.
