🌐 Chain Integration Layer
UtopiaSwap supports multiple EVM-compatible chains and is built with a modular, extensible integration layer that enables seamless access to liquidity across different networks. This layer abstracts the complexity of cross-chain environments while maintaining security and performance.
🧬 Supported Networks
UtopiaSwap currently supports:
- Ethereum (Mainnet)
- Polygon (POS)
- BNB Smart Chain
- Base
- Optimism
- Celo
More chains will be integrated as the platform evolves, prioritizing networks with strong DeFi ecosystems and reliable infrastructure.
🔌 Integration Approach
Each supported chain is integrated through a chain adapter module, which standardizes and isolates chain-specific logic. This includes:
- Native token and gas handling
- RPC node management
- Token address and decimal normalization
- Chain-specific quirks (e.g., nonce behavior, confirmations)
These adapters communicate with the routing layer, smart contracts, and frontend via a shared interface.
🧱 Architecture (Horizontal Flow)
| 🧑💻 Frontend UI | 🔌 Chain Adapter Interface | 🧩 Chain Adapter (ETH/POLY/etc.) | 🛠️ Smart Contracts | 💧 Liquidity Sources |
|---|---|---|---|---|
| User interacts with UI and selects chain/token | Normalized gateway for chain logic | Handles gas, RPC, decimals, token mapping | Executes routed swaps | DEXs like Uniswap, Balancer, etc. |
🔄 Runtime Chain Switching
- Users can seamlessly switch chains using their wallet (e.g., MetaMask).
- UtopiaSwap detects the selected chain and automatically updates:
- RPC endpoints
- Available tokens
- Supported DEX aggregators
- No page reload or reconnection needed.
🧠 Chain Metadata Management
Each chain is defined in a metadata registry, which includes:
- Chain ID
- Native token symbol
- Wrapped native token address (e.g., WETH, WBNB)
- Explorer URL
- Contract addresses
- Enabled features (e.g., gas estimation logic, slippage tuning)
🔒 Security Considerations
- RPC failover and fallback nodes are configured to avoid downtime.
- Strict validation of token lists and contract responses.
- Per-chain gas limits and error handling strategies prevent failed transactions from affecting the broader platform.
🛠 Adding New Chains
Adding a new chain to UtopiaSwap requires:
- Creating a new adapter module
- Deploying contracts to the new chain
- Registering token pairs and DEX routes
- Updating frontend chain registry
- Running test scenarios for routing, slippage, and edge cases
