# Core Contracts

These are the **core Aarc contracts** deployed across supported chains.

## Liquidity Router

The **Liquidity Router** contract orchestrates cross-chain asset movements, covering swaps, bridging, and other execution steps behind the scenes.

| **Chain**       | **Chain ID** | **Router Address**                         |
| --------------- | ------------ | ------------------------------------------ |
| Ethereum        | 1            | 0xD318093C294991c7b29762283151983c05229263 |
| Polygon         | 137          | 0xD318093C294991c7b29762283151983c05229263 |
| Arbitrum        | 42161        | 0xD318093C294991c7b29762283151983c05229263 |
| Base            | 8453         | 0xD318093C294991c7b29762283151983c05229263 |
| Optimism        | 10           | 0xD318093C294991c7b29762283151983c05229263 |
| BNB Smart Chain | 56           | 0xD318093C294991c7b29762283151983c05229263 |

## Deposit Factory

The **Deposit Factory** contract generates the **unique deposit addresses** used by Aarc. Each deposit address is single-use and routes funds to the **Liquidity Router** for final execution. This design removes the need for user token allowances, reducing security risks and simplifying the onboarding flow.

| **Chain**        | **Chain ID** | **Factory Address**                        |
| ---------------- | ------------ | ------------------------------------------ |
