# 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.&#x20;
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
