# Introduction
## **Carina – The Intent-based DEX Aggregator on Sei**
Carina is an intent-based DEX aggregator built natively on the Sei Network. Instead of submitting swaps directly on-chain, users express their desired trade as a signed intent.
These intents are matched and executed by competing solvers, who work to find the best possible execution across available liquidity. By shifting execution complexity away from users, Carina helps reduce slippage and MEV exposure while delivering more consistent and efficient trading outcomes.
### Benefits of Intent Trading
#### **1. Fair and Predictable Execution**
Carina minimizes slippage and prevents MEV attacks by batching trades and executing them through solver competition. This ensures:
* Uniform pricing for all traders within a batch.
* Protection against front running and transaction reordering.
* Stable execution even during periods of high market volatility.
#### **2. Gas Free**
Carina removes the need for you to pay gas fees directly. After a trade intent is submitted, solvers handle on-chain execution and cover the associated costs. As a result:
* No gas costs for users.
* A smoother and more consistent trading flow.
#### **3. Simplified User Interaction**
Carina is built to reduce friction at every step. There’s no need to hold a native token to pay for gas, and no need to manually choose routes or liquidity sources. With fewer decisions to make, trading becomes faster, easier, and more accessible, so you can focus on the outcome rather than the mechanics behind it.
