# MegaETH Deployments (/docs/protocols/v3/deployments/v3-megaeth-deployments)

Review Uniswap v3 deployment addresses and contract references for MegaETH integrations.

> [!NOTE]
> All Uniswap v3 deployment addresses are also available on the unified [Deployments](/deployments) page and its [deployments.json](/deployments.json) feed.

The latest version of `@uniswap/v3-core`, `@uniswap/v3-periphery`, and `@uniswap/swap-router-contracts` are deployed at the addresses listed below. Integrators should **no longer assume that they are deployed to the same addresses across chains** and be extremely careful to confirm mappings below.

These addresses are final and were deployed from these npm package versions:

* [`@uniswap/v3-core@1.0.0`](https://github.com/Uniswap/uniswap-v3-core/tree/v1.0.0)
* [`@uniswap/v3-periphery@1.0.0`](https://github.com/Uniswap/uniswap-v3-periphery/tree/v1.0.0)
* [`@uniswap/swap-router-contracts@1.1.0`](https://github.com/Uniswap/swap-router-contracts/tree/v1.1.0)

## Uniswap v3 Staker
An up-to-date list of [deploy addresses by chain is hosted on GitHub](https://github.com/Uniswap/v3-staker/releases/tag/v1.0.2) for the `UniswapV3Staker` contract.

## Universal Router
The `UniversalRouter` contract is the current preferred entrypoint for ERC20 and NFT swaps, replacing, among other contracts, `SwapRouter02`. An up-to-date list of [deploy addresses by chain is hosted on GitHub](https://github.com/Uniswap/universal-router/tree/main/deploy-addresses).

## Uniswap Pool Deployments
Every Uniswap pool is a unique instance of the `UniswapV3Pool` contract and is deployed at its own unique address. The contract source code of the pool will be auto-verified on the explorer. You can browse [MegaETH contracts on Blockscout](https://megaeth.blockscout.com/) to confirm any deployment.

You can look up the address of an existing pool on [Uniswap Info](https://info.uniswap.org/#/) or by calling the `getPool` function on the `UniswapV3Factory` contract.

```solidity
getPool("0xa0b86991c6218b36c1d19d4a2e9eb0ce3606eb48", "0xc02aaa39b223fe8d0a0e5c4f27ead9083c756cc2", 3000)
```

## Wrapped Native Token Addresses
The Uniswap Protocol supports trading of ERC20 tokens. In order to swap a native asset like ETH, the Uniswap protocol wraps these assets in an ERC20 wrapped native token contract. The protocol uses the following WETH9 address on MegaETH.

| Network | ChainId | Wrapped Native Token | Address                                      |
| ------- | ------- | -------------------- | -------------------------------------------- |
| MegaETH | `4326`  | WETH                 | `0x4200000000000000000000000000000000000006` |
