X Layer Deployments

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

All Uniswap v3 deployment addresses are also available on the unified Deployments page and its 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.
