# Core Features ## Core features & design goals: 1. **Modular Extensibility**: Utilizes a flexible Adapter pattern, allowing seamless integration of new DEX protocols without altering the core router logic. 2. **Optimal Rate Discovery**: Employs sophisticated on-chain algorithms that rigorously search for swap paths maximizing the final output amount. 3. **Gas Cost Consideration**: Factors in the network transaction costs (gas fees) associated with different paths, optimizing for the *net* value received by the user. 4. **Multi-Hop Capability**: Intelligently routes trades through liquid intermediary ‘trusted tokens’ when direct liquidity between the desired pair is scarce or inefficient or when optimal. 5. **Atomic Execution**: Ensures that multi-step swaps across different DEX adapters execute as a single, indivisible transaction, guaranteeing that either the entire sequence completes successfully or the whole operation reverts, protecting user funds from partial execution failures. 6. **User Experience Enhancement**: Simplifies interactions through a unified interface and reduce transaction costs via EIP-2612 permit support --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
