## Allowlisted DEX routers (DustSweep)

DustSweep's sweep contracts can only route through these allowlisted DEX routers on Base:

| Router                             | Address                                      |
| ---------------------------------- | -------------------------------------------- |
| Uniswap Universal Router (V3+V4)   | `0x6fF5693b99212Da76ad316178A184AB56D299b43` |
| Uniswap V3 SwapRouter02            | `0x2626664c2603336E57B271c5C0b26F421741e481` |

| QuickSwap Algebra SwapRouter       | `0xe6c9bb24ddB4aE5c6632dbE0DE14e3E474c6Cb04` |
| AlienBase Router (UniV2)           | `0x8c1A3cF8f83074169FE5D7aD50B978e1cD6b37c7` |
| DackieSwap SmartRouter             | `0x195FBc5B8Fbd5Ac739C1BA57D4Ef6D5a704F34f7` |
| BaseSwap Router                    | `0x327Df1E6de05895d2ab08513aaDD9313Fe505d86` |

AlienBase trades go through its UniV2 router above, not the AlienBase SmartRouter — the SmartRouter doesn't expose an on-chain quote, so DustSweep doesn't use it.

## Aggregator fallback targets (DustSweep)

When no DEX above can trade a token, DustSweep can route that one token through an external aggregator. Only these outer aggregator contracts are allowlisted — never the individual pools or internal hops they use:

| Aggregator         | Address                                      |
| ------------------ | -------------------------------------------- |
| 0x AllowanceHolder | `0x0000000000001fF3684f28c67538d4D072C22734` |
| LI.FI Diamond      | `0x1231DEB6f5749EF6cE6943a275A1D3E7486F4EaE` |

> **User Safety Note**
> Only the contracts above (and the DustSweep router on the [previous page](dustsweep-router.md)) are part of DustSwap. Verify any address against this page or BaseScan before interacting with it.
