# X Layer Deployments (/docs/protocols/v3/deployments/v3-xlayer-deployments)

Review Uniswap v3 deployment addresses and contract references for X Layer 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.

| Contract                                                                                                                           | Address                                                                                                                           |
