Line range hint
59-63: Type mismatch between getter and setter methods.The
max_supplygetter returnsOption<TokenAmount>while the correspondingset_max_supplysetter acceptsOption<u64>. This inconsistency could lead to type conversion issues.Consider updating the setter to match the getter's type:
- fn set_max_supply(&mut self, max_supply: Option<u64>) { + fn set_max_supply(&mut self, max_supply: Option<TokenAmount>) { match self { TokenConfiguration::V0(v0) => v0.set_max_supply(max_supply), } }
🧹 Nitpick comments (21)
packages/rs-dpp/src/errors/consensus/state/token/mod.rs (1)
16-22: Consider explicit exports instead of glob operators.While using
pub use module::*is convenient, it can make breaking changes harder to track and might accidentally expose internal implementation details. Consider explicitly listing the exported types:-pub use invalid_group_position_error::*; +pub use invalid_group_position_error::InvalidGroupPositionError;This makes the public API more explicit and helps track breaking changes more effectively.
packages/rs-drive-abci/src/execution/validation/state_transition/state_transitions/batch/action_validation/token/token_mint_transition_action/state_v0/mod.rs (2)
90-90: Clarify the comment for accuracy.The comment on line 90 is misleading. It should reflect that the total supply after minting would exceed the
max_supply, not that a max supply smaller than the current supply is being set.Apply this diff to correct the comment:
- // We are trying to set a max supply smaller than the token total supply + // Minting would exceed the maximum token supply
103-103: Clarify the comment regarding overflow handling.On line 103, the comment can be more precise. Since
checked_addreturnedNone, an overflow occurred, indicating that the total supply after minting exceeds the maximum representable value.Consider updating the comment:
- // if we overflow we would also always go over max supply + // Overflow occurred; total supply after minting exceeds maximum valuepackages/rs-drive-abci/src/execution/validation/state_transition/state_transitions/batch/action_validation/token/token_config_update_transition_action/state_v0/mod.rs (2)
171-248: Consider refactoring to reduce code duplication in identity checks.Multiple match arms handle
AuthorizedActionTakers::Identity(identity_id)and perform similar identity existence checks. Refactoring this repetitive code into a helper function would improve maintainability.Example refactor:
fn validate_identity_exists( platform: &PlatformStateRef, identity_id: &Identifier, block_info: &BlockInfo, execution_context: &mut StateTransitionExecutionContext, transaction: TransactionArg, platform_version: &PlatformVersion, ) -> Result<(), SimpleConsensusValidationResult> { let (identity_balance, fee) = platform.drive.fetch_identity_balance_with_costs( identity_id.to_buffer(), block_info, true, transaction, platform_version, )?; execution_context.add_operation(ValidationOperation::PrecalculatedOperation(fee)); if identity_balance.is_none() { return Err(SimpleConsensusValidationResult::new_with_error( ConsensusError::StateError( StateError::NewAuthorizedActionTakerIdentityDoesNotExistError( NewAuthorizedActionTakerIdentityDoesNotExistError::new(*identity_id), ), ), )); } Ok(()) }Replace the repeated code in the match arms with a call to this function.
249-325: Consider refactoring to reduce code duplication in group checks.Similar to the identity checks, multiple match arms handle
AuthorizedActionTakers::Group(group_contract_position)and perform the same group existence validation. Extracting this logic into a helper function would enhance code readability.Example refactor:
fn validate_group_exists( contract: &DataContract, group_contract_position: &GroupContractPosition, ) -> Result<(), SimpleConsensusValidationResult> { if !contract.groups().contains_key(group_contract_position) { return Err(SimpleConsensusValidationResult::new_with_error( ConsensusError::StateError( StateError::NewAuthorizedActionTakerGroupDoesNotExistError( NewAuthorizedActionTakerGroupDoesNotExistError::new(*group_contract_position), ), ), )); } Ok(()) }Call this function in the relevant match arms to avoid repetition.

257-258: Add missing documentation for new imports.These new imports for
GroupV0andGroupshould have documentation comments explaining their purpose in the context of token management.
264-264: Add missing documentation for GroupStateTransitionInfo import.The
GroupStateTransitionInfoimport should have documentation explaining its role in group-based token operations.
10200-10204: Add missing documentation for token configuration imports.The new imports related to token configuration should have documentation explaining their purpose:

10208-10210: Add missing documentation for group and batch transition imports.The imports for
GroupStateTransitionInfoStatusandDocumentsBatchTransitionMethodsV1should have documentation explaining their roles in token operations.
10305-10396: Improve error handling in test_token_mint_by_owner_can_not_mint_past_max_supply.The test verifies that minting tokens beyond the max supply fails, but could be improved:
- Add assertions to verify the exact error message
- Add checks for the token's total supply before and after the failed mint
- Consider testing edge cases like minting exactly at max supply
let processing_result = platform .platform .process_raw_state_transitions( &vec![documents_batch_create_serialized_transition.clone()], &platform_state, &BlockInfo::default(), &transaction, platform_version, false, None, ) .expect("expected to process state transition"); +// Verify exact error message +let error = match &processing_result.execution_results()[0] { + StateTransitionExecutionResult::PaidConsensusError( + ConsensusError::StateError(StateError::TokenMintPastMaxSupplyError(err)), + _ + ) => err, + _ => panic!("Expected TokenMintPastMaxSupplyError"), +}; +assert_eq!(error.max_supply, 1000000); +assert_eq!(error.attempted_mint_amount, 2000000); +// Verify total supply hasn't changed +let total_supply = platform + .drive + .fetch_token_total_supply(token_id.to_buffer(), None, platform_version) + .expect("expected to fetch total supply"); +assert_eq!(total_supply, Some(100000));
14524-14525: Add missing documentation for non_group test module.The non-group test module should have documentation explaining its purpose and the test scenarios it covers.

15309-15878: Improve test coverage in test_token_config_update_by_owner_change_admin_to_a_non_existent_group_error.The test verifies error handling for non-existent groups but could be improved:

12-16: Consider adding documentation for the error type.While the implementation is correct, adding documentation comments would improve maintainability by explaining when this error occurs and how to handle it.
Add documentation like this:
+/// Error returned when attempting to set an authorized action taker identity that does not exist. +/// This typically occurs during token configuration updates when the specified identity +/// has not been registered in the platform. #[derive( Error, Debug, Clone, PartialEq, Eq, Encode, Decode, PlatformSerialize, PlatformDeserialize, )]packages/rs-dpp/src/errors/consensus/state/token/new_authorized_action_taker_group_does_not_exist_error.rs (2)
25-27: Consider adding #[must_use] attribute.The getter method returns a value that shouldn't be ignored. Adding #[must_use] would help catch cases where the return value is accidentally discarded.
+ #[must_use] pub fn group_contract_position(&self) -> GroupContractPosition { self.group_contract_position }
1-8: Consider creating a common error handling macro.All four error types follow a similar pattern with identical trait derivations and serialization attributes. Consider creating a custom macro to reduce boilerplate and ensure consistency:
/// Create a new error type with standard derive macros and serialization support macro_rules! define_consensus_error { ( $(#[doc = $doc:expr])* $vis:vis struct $name:ident { $( $field_vis:vis $field:ident: $ty:ty ),* } ) => { $(#[doc = $doc])* #[derive(Error, Debug, Clone, PartialEq, Eq, Encode, Decode, PlatformSerialize, PlatformDeserialize)] #[platform_serialize(unversioned)] $vis struct $name { $( $field_vis $field: $ty ),* } }; }Also applies to: 1-8, 1-8, 1-8
packages/rs-dpp/src/errors/consensus/state/token/token_setting_max_supply_to_less_than_current_supply_error.rs (1)
1-48: LGTM! Consider adding documentation for error conditions.The implementation is well-structured with proper error handling traits and clear error messaging. The error type effectively captures all necessary information for debugging token supply issues.
Consider adding documentation comments to describe specific scenarios when this error occurs and potential remediation steps. Example:
/// Represents an error when attempting to set a token's maximum supply to a value /// less than its current supply. /// /// # Example /// This error occurs when updating token configuration with a new max supply that /// would invalidate existing tokens in circulation. pub struct TokenSettingMaxSupplyToLessThanCurrentSupplyError {packages/rs-dpp/src/state_transition/state_transitions/document/batch_transition/batched_transition/token_burn_transition/v0_methods.rs (1)
78-82: Consider using a constant for the action prefix.The action prefix "action_token_burn" could be defined as a constant to ensure consistency across the codebase.
+const TOKEN_BURN_ACTION_PREFIX: &[u8] = b"action_token_burn"; impl TokenBurnTransition { pub fn calculate_action_id_with_fields( token_id: &[u8; 32], owner_id: &[u8; 32], identity_contract_nonce: IdentityNonce, burn_amount: TokenAmount, ) -> Identifier { - let mut bytes = b"action_token_burn".to_vec(); + let mut bytes = TOKEN_BURN_ACTION_PREFIX.to_vec(); bytes.extend_from_slice(token_id);packages/rs-dpp/src/state_transition/state_transitions/document/batch_transition/batched_transition/token_config_update_transition/v0_methods.rs (1)
77-90: Consider defining the action prefix as a constant.The implementation looks good, but the byte string
"action_token_config_update"could be defined as a constant at the module level for better maintainability and reusability.+const TOKEN_CONFIG_UPDATE_ACTION_PREFIX: &[u8] = b"action_token_config_update"; + impl TokenConfigUpdateTransition { pub fn calculate_action_id_with_fields( token_id: &[u8; 32], owner_id: &[u8; 32], identity_contract_nonce: IdentityNonce, update_token_config_item: u8, ) -> Identifier { - let mut bytes = b"action_token_config_update".to_vec(); + let mut bytes = TOKEN_CONFIG_UPDATE_ACTION_PREFIX.to_vec(); bytes.extend_from_slice(token_id);packages/rs-drive/src/drive/tokens/system/fetch_token_total_supply/v0/mod.rs (1)
33-58: Consider adding error context for fee calculation failures.While the implementation is correct, consider adding context to fee calculation errors to make debugging easier.
let fees = Drive::calculate_fee( None, Some(drive_operations), &block_info.epoch, self.config.epochs_per_era, platform_version, None, - )?; + ).map_err(|e| Error::from(e).context("Failed to calculate fees for token total supply fetch"))?; Ok((token_amount, fees))packages/rs-dpp/src/state_transition/state_transitions/document/batch_transition/v1/v0_methods.rs (1)
34-34: Consider breaking down the import line for better readability.The import line is quite long and combines multiple token-related types. Consider breaking it into multiple lines for better maintainability.

82-82: LGTM! Byte extension order matches parameter order.The byte extension order has been correctly updated to maintain consistency with the parameter reordering, preserving the deterministic nature of the action ID calculation.
76-76: Verify all callers are updated for the breaking parameter reorder.The parameter reordering in
calculate_action_id_with_fieldsis a breaking change. While the change appears intentional and consistent with other changes, we should ensure all callers are updated.✅ Verification successful
Parameter reordering is consistently applied across the codebase
The parameter ordering in
calculate_action_id_with_fieldsis consistent across all token-related transitions and their respective callers. All implementations and calls follow the same pattern: token_id, owner_id, identity_contract_nonce, followed by the transition-specific parameter.🏁 Scripts executed

4-10: Well-structured error modules for token validation scenarios!The new error modules provide comprehensive coverage for various token validation scenarios including group positions, authorization checks, token destinations, and supply constraints. The naming is clear and consistent with Rust conventions.
packages/rs-dpp/src/errors/consensus/state/token/invalid_group_position_error.rs (2)
37-38: Good addition of the getter method formax_group_position.The new getter method
max_group_position()properly provides access to themax_group_positionfield.
48-48: Verify the impact of changing the error variant fromBasicErrortoStateError.Changing the error conversion to use
StateError::InvalidGroupPositionErrormay affect error handling elsewhere in the codebase. Ensure that all references and handlers for this error are updated accordingly.packages/rs-drive-abci/src/execution/validation/state_transition/state_transitions/batch/action_validation/token/token_mint_transition_action/state_v0/mod.rs (1)
76-123: Implementing max supply validation logic correctly.The added logic appropriately checks that minting does not exceed the
max_supplydefined in the token configuration. It handles potential overflows and corrupted state scenarios effectively.packages/rs-drive-abci/src/execution/validation/state_transition/state_transitions/batch/action_validation/token/token_config_update_transition_action/state_v0/mod.rs (4)
94-128: Max supply update validation is correctly implemented.The logic correctly ensures that the new
max_supplyis not less than the currenttoken_total_supply, preventing inconsistencies in token circulation.
129-148: Proper validation of new tokens destination identity.The code correctly checks if the specified
NewTokensDestinationIdentityexists, enhancing security by preventing tokens from being assigned to non-existent identities.
149-170: Validating the existence of the main control group.The check ensures that the provided
MainControlGroupexists within the data contract's groups, maintaining data integrity.
326-379: Validating main control group presence forAuthorizedActionTakers::MainGroup.The code correctly checks if the
main_control_groupis set before allowing it to be used as anAuthorizedActionTaker, ensuring proper configuration.packages/rs-dpp/src/errors/consensus/state/token/new_authorized_action_taker_main_group_not_set_error.rs (1)

23-25: Consider implementing Copy for Identifier.The getter method returns a copy of the Identifier. If Identifier is small and Copy is cheap, implementing Copy would allow returning by value instead of reference.
Let's check the size and traits of Identifier:
packages/rs-dpp/src/errors/consensus/state/token/token_mint_past_max_supply_error.rs (1)
1-60: LGTM! Consider adding overflow protection.The error type is well-implemented with proper use of TokenAmount for consistent handling of token values.
Since this error is used in minting validation, we should verify that overflow checks are implemented in the minting logic. Let's check the implementation:
✅ Verification successful
Supply validation is properly implemented with overflow protection
The implementation in
token_mint_transition_action/state_v0/mod.rsincludes both overflow checks and max supply validation:
- Checks for overflow when adding mint_amount to current_supply
- Validates that the resulting total doesn't exceed max_supply
- Provides detailed error information when limits are exceeded

batch_feature_version,config_update_feature_version,base_feature_version) but only uses the batch version in the implementation. Ensure this aligns with the versioning strategy.✅ Verification successful
Feature version handling is correctly implemented.
The current implementation follows a deliberate design pattern where:
batch_feature_versionis used for version selection in the batch transition system- Other feature versions are intentionally unused parameters (marked with
_) to maintain API consistency and future extensibility🏁 Scripts executed
