1-11800: Security considerationsThe code has several important security features but could benefit from additional safeguards:
Token Operations:
- Verify all token operations have proper authorization checks
- Add rate limiting for token operations
- Consider adding emergency pause functionality
Group Management:
- Add timeouts for group operations
- Implement quorum requirements for critical operations
- Add member removal capabilities
Configuration Updates:
- Add delays for critical configuration changes
- Implement multi-sig requirements for high-risk operations
Consider implementing these additional security measures to enhance the token distribution model's security.

88-109: Exponential function usage is well explained.
No immediate issues, though in calling code, consider limiting large exponents to evade numeric overflow.packages/rs-drive-abci/src/execution/validation/state_transition/state_transitions/batch/mod.rs (5)
10205-10205: Fix line indentationThe line is incorrectly indented compared to surrounding code.
+ use dpp::data_contract::associated_token::token_distribution_rules::accessors::v0::TokenDistributionRulesV0Setters;
10978-10984: Simplify chained method callsThe code has multiple chained method calls that can be simplified for better readability.

1-11800: Overall architecture feedbackThe implementation demonstrates a robust token distribution model with several key strengths:
- Comprehensive test coverage for various token operations
- Strong validation of token operations
- Support for group-based authorization
- Proper handling of token freezing/unfreezing
- Well-implemented token configuration updates
However, there are some areas that could be improved:
Error Handling:
- Consider adding more specific error types for token operations
- Add error context information for better debugging
Documentation:
- Add documentation for complex token operations
- Document the group authorization model
Code Organization:
- Consider splitting large test modules into smaller files
- Extract common test setup code into helper functions
packages/rs-dpp/src/data_contract/associated_token/token_distribution_rules/mod.rs (1)
18-26: Consider adding documentation for the Display implementation.While the implementation is correct, adding documentation would help explain the formatting choices and make it clear that it delegates to the inner type's Display implementation.
+/// Implements Display for TokenDistributionRules by delegating to the inner type's +/// Display implementation. This ensures consistent formatting across versions. impl fmt::Display for TokenDistributionRules {packages/rs-dpp/src/data_contract/associated_token/token_perpetual_distribution/mod.rs (2)
10-15: LGTM! Consider adding documentation.The enum is well-structured with proper versioning. Consider adding documentation to explain the purpose of
TokenPerpetualDistributionand why it needsPartialOrd.+/// Represents perpetual token distribution rules with versioning support. +/// Implements PartialOrd to allow comparison of distribution configurations. #[derive(Serialize, Deserialize, Encode, Decode, Debug, Clone, PartialEq, Eq, PartialOrd, From)]
17-25: Consider creating a macro for versioned enum pattern.This Display implementation is identical to
TokenDistributionRules. Consider creating a macro to reduce boilerplate for versioned enums./// Example macro (to be placed in a common utility module): macro_rules! impl_versioned_display { ($type:ident) => { impl fmt::Display for $type { fn fmt(&self, f: &mut fmt::Formatter<'_>) -> fmt::Result { match self { Self::V0(v0) => write!(f, "{}", v0) } } } }; } // Usage: impl_versioned_display!(TokenPerpetualDistribution);packages/rs-dpp/src/data_contract/associated_token/token_pre_programmed_distribution/v0/mod.rs (1)
10-14: Add documentation and consider performance implications.The nested BTreeMap structure is well-chosen for ordered timestamps, but consider:
- Adding documentation to explain the structure and its performance characteristics
- For large datasets, consider implementing methods to efficiently batch process distributions
+/// Represents pre-programmed token distributions organized by timestamps. +/// Uses BTreeMap for ordered access with O(log n) complexity. +/// - Outer map: Timestamp -> Distribution map +/// - Inner map: Identifier -> Token amount for each recipient #[derive(Serialize, Deserialize, Decode, Encode, Debug, Clone, PartialEq, Eq)] #[serde(rename_all = "camelCase")] pub struct TokenPreProgrammedDistributionV0 { + /// Nested map structure for timestamp-based token distributions. + /// Performance note: Operations have O(log n) complexity where n is the number of timestamps. pub distributions: BTreeMap<TimestampMillis, BTreeMap<Identifier, TokenAmount>>, }packages/rs-dpp/src/lib.rs (1)
82-83: Add documentation for interval types.While the type aliases are well-chosen, they would benefit from documentation explaining:
- The purpose and use case for each interval type
- Any constraints or valid value ranges
- The relationship between these intervals
+ /// Represents an interval in epochs. Valid values are non-zero positive integers. pub type EpochInterval = u16; + /// Represents an interval in block heights. Must be greater than zero. pub type BlockHeightInterval = u64; + /// Represents a time interval in milliseconds. Must be greater than zero. pub type TimestampMillisInterval = u64;Also applies to: 86-87, 91-92
packages/rs-dpp/src/data_contract/associated_token/token_perpetual_distribution/v0/mod.rs (2)
11-27: Consider enhancing enum documentation with examples.The enum variants are well-documented with basic descriptions. Consider adding examples for each variant to illustrate typical usage scenarios and parameter values.
#[derive(Serialize, Deserialize, Decode, Encode, Debug, Clone, PartialEq, Eq, PartialOrd)] pub enum RewardDistributionType { - /// A fixed amount of tokens is emitted every n blocks + /// A fixed amount of tokens is emitted every n blocks + /// Example: BlockFixed(100, 1000) // Emit 1000 tokens every 100 blocks BlockFixed(BlockHeightInterval, TokenAmount),
38-70: Consider optimizing string formatting in Display implementation.The current implementation creates intermediate String allocations for None cases. Consider using references to static strings to reduce allocations.
- None => "None".to_string(), + None => "None",packages/rs-dpp/src/data_contract/associated_token/token_distribution_rules/v0/mod.rs (1)
48-79: Consider optimizing string formatting in Display implementation.Similar to the previous file, the implementation creates unnecessary String allocations for None cases.
- None => "None".to_string(), + None => "None",packages/rs-dpp/src/data_contract/change_control_rules/mod.rs (1)
130-138: Consider adding documentation for the Display implementation.The Display implementation is correct but would benefit from documentation explaining the string format produced by the v0 implementation.
Apply this diff to add documentation:
+/// Implements Display for ChangeControlRules by delegating to the inner type's Display implementation. +/// The string format follows the format defined by the v0 implementation. impl fmt::Display for ChangeControlRules { fn fmt(&self, f: &mut fmt::Formatter<'_>) -> fmt::Result { match self { ChangeControlRules::V0(v0) => { write!(f, "{}", v0) //just pass through } } } }packages/rs-dpp/src/data_contract/associated_token/token_distribution_rules/v0/accessors.rs (1)
1-114: LGTM! Consider adding examples to documentation.The implementation is well-structured with clear separation of concerns between getters and setters. The code follows Rust best practices and provides comprehensive access to distribution rules.
Consider adding usage examples to the documentation for complex scenarios, such as:
// Example: Setting up perpetual distribution let mut rules = TokenDistributionRulesV0::default(); rules.set_perpetual_distribution(Some(TokenPerpetualDistribution::new(...))); rules.set_perpetual_distribution_rules(ChangeControlRules::new(...));packages/rs-dpp/src/data_contract/change_control_rules/v0/mod.rs (1)
163-181: LGTM! Consider adding Display implementation tests.The Display implementation is well-structured and properly formats all fields. The output format is clear and readable.
Consider adding tests to verify the Display implementation:
#[test] fn test_change_control_rules_display() { let rules = ChangeControlRulesV0 { authorized_to_make_change: AuthorizedActionTakers::NoOne, admin_action_takers: AuthorizedActionTakers::NoOne, changing_authorized_action_takers_to_no_one_allowed: true, changing_admin_action_takers_to_no_one_allowed: false, self_changing_admin_action_takers_allowed: true, }; let expected = "ChangeControlRulesV0 {\n authorized_to_make_change: NoOne,\n ...}"; assert!(rules.to_string().starts_with(expected)); }packages/rs-dpp/src/data_contract/associated_token/token_distribution_rules/accessors/mod.rs (1)
98-158: Consider adding validation in setters.While the setter implementation is clean, consider adding validation logic to ensure the rules being set are consistent with the token's configuration.
For example, you could add validation in
set_perpetual_distribution:fn set_perpetual_distribution( &mut self, perpetual_distribution: Option<TokenPerpetualDistribution>, ) { + // Validate the distribution configuration + if let Some(dist) = &perpetual_distribution { + // Add validation logic here + } match self { TokenDistributionRules::V0(v0) => v0.set_perpetual_distribution(perpetual_distribution), } }packages/rs-dpp/src/data_contract/associated_token/token_configuration/accessors/mod.rs (1)
72-82: Good architectural decision to consolidate distribution rules.The addition of
distribution_rulesanddistribution_rules_mutmethods provides a cleaner interface for managing token distribution configurations. This change improves modularity and maintainability.Consider documenting the migration path for existing implementations that might be using the removed identity management methods.
packages/rs-dpp/src/data_contract/associated_token/token_configuration/v0/accessors.rs (2)
130-138: Thorough implementation of group position collection.The code properly integrates distribution rules into the group position collection process. However, consider extracting the group position collection logic into a separate method for better maintainability.
Consider refactoring to:
fn all_used_group_positions(&self) -> BTreeSet<GroupContractPosition> { let mut group_positions = BTreeSet::new(); + self.collect_distribution_rule_positions(&mut group_positions); + // ... rest of the implementation } + +fn collect_distribution_rule_positions(&self, positions: &mut BTreeSet<GroupContractPosition>) { + add_from_change_control_rules( + self.distribution_rules.new_tokens_destination_identity_rules(), + ); + add_from_change_control_rules( + self.distribution_rules.minting_allow_choosing_destination_rules(), + ); + add_from_change_control_rules(self.distribution_rules.perpetual_distribution_rules()); +}
180-182: Consider adding debug assertions for distribution rules.The setter for distribution rules could benefit from debug assertions to catch potential issues early in development.
fn set_distribution_rules(&mut self, rules: TokenDistributionRules) { + debug_assert!(matches!(rules, TokenDistributionRules::V0(_)), + "Attempting to set non-V0 distribution rules on V0 configuration"); self.distribution_rules = rules; }packages/rs-drive-abci/src/execution/validation/state_transition/state_transitions/data_contract_update/mod.rs (1)
1306-1524: Well-structured test cases for token immutability.The test suite comprehensively covers token immutability requirements:
- Preventing token removal
- Preventing token modification
- Proper error handling and validation
The tests are well-organized with clear setup, execution, and verification phases.
However, consider adding the following test cases for completeness:
- Attempting to modify multiple tokens simultaneously
- Edge cases with token positions (e.g., non-existent positions)
packages/rs-dpp/src/data_contract/associated_token/token_pre_programmed_distribution/mod.rs (1)
16-24: Consider enhancing the Display implementation.While the current implementation is functional, consider adding version information to the display output for better debugging.
impl fmt::Display for TokenPreProgrammedDistribution { fn fmt(&self, f: &mut fmt::Formatter<'_>) -> fmt::Result { match self { TokenPreProgrammedDistribution::V0(v0) => { - write!(f, "{}", v0) //just pass through + write!(f, "V0({})", v0) } } } }packages/rs-drive-abci/src/execution/validation/state_transition/state_transitions/batch/action_validation/token/token_mint_transition_action/state_v0/mod.rs (4)
Line range hint
95-103: Improve error message specificity.The error message for corrupted drive state could be more informative by including the context of the operation.
- "token {} total supply not found", + "token {} total supply not found during mint validation",
Line range hint
61-91: Consider extracting supply validation logic.The max supply validation logic is complex enough to warrant its own method. This would improve readability and make the code more maintainable.
impl TokenMintTransitionAction { fn validate_max_supply( &self, token_total_supply: u64, max_supply: u64, ) -> Result<SimpleConsensusValidationResult, Error> { match token_total_supply.checked_add(self.mint_amount()) { Some(total_supply_after_mint) if total_supply_after_mint <= max_supply => { Ok(SimpleConsensusValidationResult::new()) } _ => Ok(SimpleConsensusValidationResult::new_with_error( ConsensusError::StateError(StateError::TokenMintPastMaxSupplyError( TokenMintPastMaxSupplyError::new( self.token_id(), self.mint_amount(), token_total_supply, max_supply, ), )), )), } } }
Line range hint
106-132: Extract recipient validation to a helper function.The recipient validation logic could be moved to a separate method to improve code organization and reusability.
impl TokenMintTransitionAction { fn validate_recipient( &self, platform: &PlatformStateRef, owner_id: Identifier, transaction: TransactionArg, execution_context: &mut StateTransitionExecutionContext, platform_version: &PlatformVersion, ) -> Result<SimpleConsensusValidationResult, Error> { let recipient = self.identity_balance_holder_id(); if recipient == owner_id { return Ok(SimpleConsensusValidationResult::new()); } let balance = platform.drive.fetch_identity_balance( recipient.to_buffer(), transaction, platform_version, )?; execution_context.add_operation(ValidationOperation::RetrieveIdentity( RetrieveIdentityInfo::only_balance(), )); match balance { Some(_) => Ok(SimpleConsensusValidationResult::new()), None => Ok(SimpleConsensusValidationResult::new_with_error( ConsensusError::StateError(StateError::RecipientIdentityDoesNotExistError( RecipientIdentityDoesNotExistError::new(recipient), )), )), } } }
Line range hint
32-145: Consider adding const assertions for numeric limits.The implementation handles overflow checks well but could benefit from const assertions to validate numeric limits at compile time.
Add the following at the module level:
const _: () = assert!(std::u64::MAX > 1_000_000_000_000, "u64 must be large enough to handle token amounts");

packages/rs-dpp/src/data_contract/associated_token/token_configuration/methods/apply_token_configuration_item/v0/mod.rs (10)
3-5: Imports look consistent.
These imports seamlessly integrateTokenDistributionRulesV0GettersandTokenDistributionRulesV0Settersinto the existing token configuration flows with no obvious issues.
42-43: No concerns with direct setter usage.
Callingset_new_tokens_destination_identityhere is straightforward. Ensure that any specialized validation of theidentityis done upstream if necessary.
48-49: Authorized action takers updated properly.
Usingnew_tokens_destination_identity_rules_mut()is consistent with the modular approach to distribution rules.
53-54: Admin action takers updated properly.
This closely mirrors patterns used in previous blocks.
58-59: Allow choosing destination is set correctly.
Again, no functional or style issues are evident.
64-65: Control group assignment is consistent.
Matches earlier patterns for control group modifications.
71-73: Admin group setters are consistent with design.
No issues.
75-78: Perpetual distribution inclusion is logically consistent.
Callingset_perpetual_distributionintegrates well with the rest of the distribution rules.
79-83: Perpetual distribution control group matches pattern.
No concerns.
84-86: Perpetual distribution admin group also follows pattern.
Assigning admin action takers remains consistent and readable.packages/rs-dpp/src/data_contract/associated_token/token_perpetual_distribution/distribution_function/mod.rs (8)
1-5: Imports and module structure are appropriate.
Usingordered_float::NotNanhelps ensure safe handling of floating-point values for distribution logic.
8-28: Excellent documentation for LinearInteger.
The doc comments clearly explain usage, formula, and examples. This is highly maintainable.
29-49: Clear extension for LinearFloat.
Floating-point slope adds flexibility, andNotNan<f64>is a good safeguard.
50-70: PolynomialInteger variant is clearly documented.
Consider verifying input domain constraints for exponents (n >= 1) in calling code to avoid edge cases.
71-87: PolynomialFloat extends polynomial curves to fractional powers.
Be mindful of complex number edges ifn< 0. Possibly enforce domain constraints at a higher layer.
110-130: Logarithmic function is functionally comprehensive.
Logs require positivex. Ensure domain checks in upstream logic.
131-143: Stepwise approach offers advanced schedule control.
The vector-based approach is flexible. Confirm step intervals align with block or epoch definitions.
145-196: Display implementation is thorough.
Formatting each variant fosters clearer logs and error messages. This is a clean and well-structured approach.packages/rs-dpp/src/data_contract/associated_token/token_perpetual_distribution/distribution_function/encode.rs (4)
1-5: Imports are correct for serialization.
No concerns regarding re-exports or side-effects.
6-54: Encode trait implementation is consistent and thorough.
Assigning a variant index is straightforward, and usinginto_inner()forNotNanis suitably handled.
56-120: Decode trait implementation effectively guards against NaN.
Returning a decode error on invalid floats is essential for robust domain handling.
122-179: BorrowDecode trait supports efficient decoding.
Mirroring theDecodelogic while preserving references is a nice optimization. This matches Rust best practices for reducing copies.packages/rs-dpp/src/data_contract/associated_token/token_distribution_rules/mod.rs (1)
8-13: LGTM! Well-structured versioned enum.The
TokenDistributionRulesenum is well-designed with proper versioning support through serde tags and follows semantic versioning conventions.packages/rs-dpp/src/data_contract/associated_token/token_pre_programmed_distribution/v0/mod.rs (1)
17-28: LGTM! Well-formatted Display implementation.The Display implementation provides clear, hierarchical formatting of the distribution data.
packages/rs-dpp/src/data_contract/associated_token/token_distribution_rules/accessors/v0/mod.rs (1)
6-73: Well-structured accessor traits with comprehensive documentation!The traits provide a clean and well-documented interface for managing token distribution rules. The separation of getters and setters, consistent method naming, and appropriate use of mutability demonstrate good design practices.
packages/rs-dpp/src/data_contract/associated_token/token_distribution_rules/v0/mod.rs (1)
38-46: Verify if the default change control rules are too restrictive.The default implementation sets all permissions to
NoOneand disables all changes. This might be too restrictive for typical use cases and could lead to tokens being permanently locked down.Consider if a more permissive default would be more appropriate, or if this is intentionally restrictive for security reasons.

packages/rs-dpp/src/data_contract/associated_token/token_configuration/accessors/v0/mod.rs (3)
3-3: LGTM! Import added for new TokenDistributionRules type.The import aligns with the new distribution rules functionality being introduced.
31-35: LGTM! New getter methods for distribution rules.The addition of both immutable and mutable accessors for distribution rules follows Rust's best practices for encapsulation.
80-81: LGTM! Setter method for distribution rules.The setter method complements the getter methods, providing a complete interface for managing distribution rules.
