defiQUG 2b52cc6e32 refactor(archive): move historical contracts and adapters to archive directory

- Archived multiple non-EVM adapters (Algorand, Hedera, Tron, TON, Cosmos, Solana) and compliance contracts (IndyVerifier) to `archive/solidity/contracts/`.
- Updated documentation to reflect the historical status of archived components.
- Adjusted `foundry.toml` and `README.md` for clarity on historical dependencies and configurations.
- Enhanced Makefile and package.json scripts for improved contract testing and building processes.
- Removed obsolete contracts (AlltraCustomBridge, CommodityCCIPBridge, ISO4217WCCIPBridge, VaultBridgeAdapter) from the main directory.
- Updated implementation reports to indicate archived status for various components.

Universal Cross-Chain Asset Hub - Final Implementation Report

Completion Date: 2026-01-24
Implementation Status: ✅ ALL PHASES COMPLETE

Executive Summary

Successfully implemented a production-grade, infinitely extensible cross-chain asset hub that supports:

10+ asset types (tokens, GRU, eMoney, CBDCs, commodities, securities)

Extensibility Mechanisms Implemented

1. Plugin Architecture ✅

// Historical plugin architecture:
pluginRegistry.registerPlugin(
    PluginType.AssetTypeHandler,
    "NewAssetType",
    handlerAddress,
    "1.0.0"
);
// No core contract changes!

2. Upgradeable Contracts ✅

// All major contracts inherit:
contract MyContract is 
    Initializable,
    UUPSUpgradeable,
    AccessControlUpgradeable
{
    function _authorizeUpgrade(address) internal override onlyRole(UPGRADER_ROLE) {}
}

3. Registry-Based Configuration ✅

// No hardcoded addresses:
address router = configRegistry.getAddress(
    address(bridge),
    keccak256("CCIP_ROUTER")
);

4. Modular Bridges ✅

// Each asset type can have specialized bridge:
orchestrator.registerAssetTypeBridge(
    AssetType.Custom,
    customBridgeAddress
);

5. Composable Compliance ✅

// Stack compliance modules:
bridgeModuleRegistry.registerModule(
    ModuleType.PreBridgeHook,
    complianceModuleAddress
);

6. Multi-Source Liquidity ✅

// Add new liquidity provider:
liquidityManager.addProvider(
    newProviderAddress,
    priority
);

7. Event-Driven Integration ✅

// All operations emit events:
event BridgeExecuted(...);
event AssetApproved(...);
event ProposalExecuted(...);

Future blockchains

Built-in Compliance

KYC/AML integration points
Jurisdiction filtering
Accredited investor verification
Certificate validation

Optimization: Gas optimization and profiling

Production Deployment

Deploy Phase 1-5 using deployment scripts
Transfer to Multi-Sig (never keep admin as EOA)
Monitor 24/7 for first 48 hours
Gradual Rollout (start with WETH, LINK)

Post-Launch

Add Asset Types (carbon credits, RWAs, etc.)
Expand Chains (more EVM and non-EVM)
