🔧 Technical Implementation Details

Diamond Implementation

Recommended Libraries

Nick Mudge's Diamond reference implementation
OpenZeppelin's access control (if compatible)
Custom storage patterns

Storage Pattern

library DiamondStorage {
    struct AppStorage {
        // Shared storage across facets
        mapping(address => uint256) balances;
        mapping(address => mapping(address => uint256)) allowances;
        // ... other shared state
    }
    
    function diamondStorage() internal pure returns (AppStorage storage ds) {
        bytes32 position = keccak256("diamond.storage");
        assembly {
            ds.slot := position
        }
    }
}

Facet Implementation Pattern

contract ERC20Facet {
    using DiamondStorage for DiamondStorage.AppStorage;
    
    function transfer(address to, uint256 amount) external returns (bool) {
        DiamondStorage.AppStorage storage ds = DiamondStorage.diamondStorage();
        // Implementation
    }
}

ISO Registry Pattern

contract ISORegistry {
    // ISO 4217: Currency codes
    mapping(string => address) public currencyCodeToToken;
    mapping(address => string) public tokenToCurrencyCode;
    
    // ISO 6166: Securities identifiers
    mapping(string => address) public isinToContract;
    mapping(address => string) public contractToIsin;
    
    // ISO 17442: Legal Entity Identifiers
    mapping(string => EntityInfo) public leiToEntity;
    mapping(address => string) public entityToLei;
    
    // Events
    event CurrencyCodeRegistered(string code, address token);
    event ISINRegistered(string isin, address contract);
    event LEIRegistered(string lei, address entity);
}
