## Version notes

* **V1** (`DustSweepRouter`) — legacy, Uniswap V3 only, max 10 tokens per sweep, plain approvals.
* **V2** (`DustSweepPermit2RouterV2`) — Permit2-based, all-or-nothing execution (any failed swap leg reverts the whole sweep), no native ETH output, no pause switch.
* **V3** (`DustSwapSweepRouter`, current) — adds native ETH output, pause switch, per-sweep fee override, and a fee binding in the Permit2 witness. Built with OpenZeppelin `Ownable`, `ReentrancyGuard`, and `Pausable`.
