Cross Chain Bridge Expansion – Networks and Functionalities

This update introduces a flexible and modular cross-chain bridge system, making it simple to transfer assets and interact across multiple blockchain networks. The following networks are now fully supported:

• Ethereum: Enables native asset transfers, token swaps, and multi-chain transactions using Wormhole and LayerZero.
• Solana: Offers fast, low-latency transfers with dedicated support for Solana’s account structure.
• Base: Focuses on efficiency and gas cost reduction, with dynamic fee and slippage management.
• Polkadot: Integrates via the XCM protocol, allowing asset movement and messaging between parachains and relay chains.
• LayerZero: Provides universal bridge capabilities for EVM-compatible chains, ensuring secure and decentralized communication.
• Wormhole: Facilitates cross-chain transfers of assets and NFTs, with thorough validation and security checks.
• LayerSwap: Supports cross-exchange transfers, automating asset deposits and withdrawals.

Key Features and Improvements:

• Unified Bridge API: Simple endpoints for starting, tracking, and managing cross-chain transfers, including strong input validation and error handling.
• Advanced Security: Includes circuit breakers, blacklist/whitelist management, rate limiting, and real-time audit logs to keep operations safe.
• Optimized Performance: Features dynamic gas and slippage control, batch transaction processing, and route selection based on live network conditions.
• Extensive End-to-End Testing: Over 600 automated tests covering address validation, transaction execution, edge cases, interoperability, and security.
• Comprehensive Configuration: Detailed environment and configuration files for RPC endpoints, bridge settings, limits, and security options.
• Robust Monitoring and Reporting: Built-in monitoring of bridge events, transaction statuses, and anomaly detection, with support for external notifications.
