Universal Router 2.2.0 adds support for Uniswap v4 permissioned pools.

Highlights

  • Extends the v4 router integration with PermissionedV4Router, preserving standard v4 swaps while adding permissioned-pool support.
  • Supports swaps through v4 permission adapters.
  • Adds Permit2-based payment and wrapping for permissioned tokens.
  • Adds permissionsAdapterFactory to RouterParameters.
  • Allows permissioned-pool support to be disabled by configuring the factory as address(0).
  • Retains standard v4 pool behavior alongside permissioned-pool routing.
  • Sweeps permissions-adapter currencies as their underlying token.
  • Pins v4-periphery to a7af5b34.

Breaking changes

The Universal Router constructor parameters now include permissionsAdapterFactory. Deployment tooling and constructor encoding must be updated accordingly.

Build

Built at optimizer_runs = 1 with solc 0.8.26 and the cancun EVM version, producing a 23,233-byte runtime. The v4-periphery submodule is pinned to a7af5b34.
