Add Oracle Aggregator and CCIP Integration
- Introduced Aggregator.sol for Chainlink-compatible oracle functionality, including round-based updates and access control. - Added OracleWithCCIP.sol to extend Aggregator with CCIP cross-chain messaging capabilities. - Created .gitmodules to include OpenZeppelin contracts as a submodule. - Developed a comprehensive deployment guide in NEXT_STEPS_COMPLETE_GUIDE.md for Phase 2 and smart contract deployment. - Implemented Vite configuration for the orchestration portal, supporting both Vue and React frameworks. - Added server-side logic for the Multi-Cloud Orchestration Portal, including API endpoints for environment management and monitoring. - Created scripts for resource import and usage validation across non-US regions. - Added tests for CCIP error handling and integration to ensure robust functionality. - Included various new files and directories for the orchestration portal and deployment scripts.

## 💰 Gas Cost Estimates
|
||||
|
||||
**Per Chain** (all 5 contracts):
|
||||
- **Avalanche**: ~8,760,000 gas units
|
||||
- **Base**: ~8,760,000 gas units
|
||||
- **Arbitrum**: ~8,760,000 gas units
|
||||
- **Optimism**: ~8,760,000 gas units
|
||||
|
||||
**Note**: Run `./scripts/deployment/get-multichain-gas-prices.sh` for real-time estimates.
|
||||

|
||||
|
||||
## ✅ Next Steps
|
||||
|
||||
1. **Configure `.env`** with all required variables
|
||||
2. **Fund wallets** on each chain with native tokens
|
||||
3. **Test gas price fetching**: `./scripts/deployment/get-multichain-gas-prices.sh`
|
||||
4. **Deploy contracts** to each chain
|
||||

|
||||
|
||||
**Total Chains Now Supported**: 9 (Ethereum Mainnet, Cronos, BSC, Polygon, Gnosis, Avalanche, Base, Arbitrum, Optimism)
