Issue #1 - Contract: Cross-Chain Asset Data Structures and Enums

[ONEONUORA]

📝 Description

Implement the core data structures and enums for cross-chain asset support in the inheritance contract.

🎯 Acceptance Criteria

• Create SupportedChain enum with all supported blockchains
• Create CrossChainAsset struct for multi-chain asset representation
• Create BridgeProtocol enum for different bridge protocols
• Create CrossChainInheritancePlan struct
• Add validation functions for cross-chain data

🔧 Implementation Details

Required Enums and Structs

#[contracttype]
#[derive(Clone, Debug, Eq, PartialEq)]
pub enum SupportedChain {
    Stellar,
    Ethereum,
    Bitcoin,
    Polygon,
    Arbitrum,
    BinanceSmartChain,
    Avalanche,
}

#[contracttype]
#[derive(Clone, Debug, Eq, PartialEq)]
pub enum BridgeProtocol {
    Allbridge,
    Wormhole,
    LayerZero,
    ChainlinkCCIP,
}

#[contracttype]
#[derive(Clone, Debug, Eq, PartialEq)]
pub struct CrossChainAsset {
    pub chain: SupportedChain,
    pub contract_address: Address,
    pub amount: u128,
    pub asset_symbol: String,
    pub bridge_protocol: BridgeProtocol,
}

🧪 Testing Requirements

• Unit tests for all data structure validation
• Test enum conversions and comparisons
• Test struct serialization/deserialization
• Validate asset symbol length limits
• Test address format validation

📋 Deliverables

• Updated lib.rs with new data structures
• Validation functions for each struct
• Comprehensive unit tests
• Documentation for each data type

Estimated effort: 1 day
Difficulty: Beginner-Intermediate
