ReRelease

[0.2.0] - 2026-02-24

Added

• Mixin pattern (mo:icrc1-mo/ICRC1/mixin) for automatic endpoint generation using persistent actor class and Class+
• Inspect module (mo:icrc1-mo/ICRC1/Inspect) for cycle drain protection with two-layer defense:
  • inspect* functions (return Bool) for use in system func inspect()
  • guard* functions (trap on invalid) for inter-canister protection
  • Built-in guards in mixin for icrc1_transfer, icrc1_balance_of, icrc107_set_fee_collector, icrc21_canister_call_consent_message
  • Configurable limits via Config type and configWith() helper
• Interface module (mo:icrc1-mo/ICRC1/Interface) with extensible before/after hooks for all ICRC-1 endpoints
• ICRC-107 fee collector management: icrc107_set_fee_collector, icrc107_get_fee_collector with authorization via canSetFeeCollector
• ICRC-106 index principal: icrc106_get_index_principal, set_icrc106_index_principal with authorization via canSetIndexPrincipal
• ICRC-21 consent message support: icrc21_canister_call_consent_message with pluggable consent builders
• ICRC-10 supported standards alias: icrc10_supported_standards mirrors icrc1_supported_standards
• ICRC-85 Open Value Sharing integration via ovs-fixed for sustainable open-source funding
• defaultMixinArgs() helper for ergonomic mixin configuration with with syntax
• MixinFunctionArgs type with canTransfer, canSetFeeCollector, canSetIndexPrincipal fields
• Init() ClassPlus-compatible initialization function
• Complete README with mixin usage examples, inspect documentation, and API reference tables
• Performance benchmarks for account operations and balance operations

Changed

• Migrated to mo:core (Map, Set, List) from mo:map/mo:vector
• Migrated to Motoko 1.1.0 with Enhanced Orthogonal Persistence (64-bit heap)
• Removed mo:base dependency in favor of mo:core
• Created migration v000_002_000 for state type conversions
• Updated mops.toml to require moc = "1.1.0" toolchain

Technical Details

• Uses persistent actor class syntax (Motoko 1.1.0+)
• ClassPlus async initialization with ClassPlusInitializationManager
• Star monad error handling for transfer/mint/burn operations
• Representational Independent Hash-based deduplication
• Automatic account pruning when exceeding max_accounts
