# Intent-Based Swaps & Execution

Defi App employs an intent-based transaction model, enabling users to specify desired outcomes (e.g., “Swap 1 ETH for USDC at best route”) without manually selecting bridges or liquidity pools. This approach abstracts away complex routing decisions, improving user experience and execution efficiency.

Our transaction aggregator dynamically discovers the optimal liquidity sources across multiple chains and protocols, leveraging off-chain order flow to streamline execution.

## How It Works

Instead of executing transactions directly through on-chain liquidity sources, Defi App’s intent-based model delegates execution to solvers (also called relayers). Solvers determine the best possible route for a swap based on liquidity conditions, gas fees, and execution probability.

## Supported Exchanges

Defi App allows swap execution using the following exchanges:

* 0x
* 1inch
* Bebop
* DeBridge
* DODO
* Enso
* Jupiter
* Odos
* OpenOcean
* Paraswap
* Relay
* Stable

## Advantages

**Optimized Routing:** Off-chain solvers select the best execution path dynamically.

**Improved Reliability:** Users don’t need to worry about API failures or liquidity fragmentation.

**Gas Efficiency:** Some intent-based swaps, such as 1inch Fusion, offer gas-free execution.
