# Supported Network & Tokens

# Supported Network & Tokens

DustSweep runs on Base mainnet only. It can sweep almost any ERC-20 token with real liquidity on Base, and pays out in ETH, USDC, WETH, or USDT.

## Network

|                |                                              |
| -------------- | -------------------------------------------- |
| Network        | **Base mainnet**                             |
| Chain ID       | **8453**                                     |
| Gas token      | ETH (on Base)                                |

If your wallet is on another network, DustSweep prompts a switch to Base. Discovery, quotes, and the sweep contracts are all Base-only in this release.

## Input tokens (what you can sweep)

DustSweep is **wallet-first**: it scans every ERC-20 balance you hold rather than working from a fixed token list. A token is sweepable when all of the following hold:

* It is an ERC-20 on Base with a non-zero balance in your wallet.
* It has a reliable USD price (from market data sources).
* Its value is at least **\$0.01**.
* It has DEX liquidity on Base so a route can be found.
* It is not flagged by spam/scam heuristics.

Tokens that miss any of these checks still appear in the interface, grouped under hidden, suspicious, or unavailable — with the reason shown. See [Why Some Tokens Can't Be Swept](why-some-tokens-cant-be-swept.md).

**Native ETH cannot be a sweep input.** ETH must be wrapped to WETH first; the sweep contract works with ERC-20s only. (ETH *can* be your output — see below.)

## Output tokens (what you receive)

| Token            | Notes                                                                       |
| ---------------- | --------------------------------------------------------------------------- |
| **ETH** (native) | Default output. The contract swaps into WETH and unwraps to ETH at the end. |
| **USDC**         | Native Base USDC.                                                           |
| **WETH**         | Wrapped Ether on Base (`0x4200000000000000000000000000000000000006`).       |
| **USDT**         | Tether USD on Base.                                                         |

The output list is intentionally short and limited to major assets. This removes a common scam pattern — being tricked into "sweeping into" a worthless token — and keeps quotes reliable.

## Where the liquidity comes from

Each selected token is quoted across multiple Base venues in parallel, and the best route wins per token:

* Uniswap V3 and Uniswap V4
* Aerodrome (classic and Slipstream concentrated liquidity)
* PancakeSwap V3
* BaseSwap
* Additional allowlisted routers (AlienBase, DackieSwap) and an optional aggregator source

Only routers on DustSweep's allowlist can ever be called by the sweep contract. See [Security Model](security-model.md).

## Limits

* **Up to 50 tokens per sweep** (smart-contract limit). Larger wallets simply sweep more than once.
* **One network (Base)** — other chains: to be confirmed before publication; nothing is currently committed.
* **WETH → native ETH** is not currently supported as a direct sweep (the contract does not allow input = output; an unwrap-only step is not implemented yet).

## FAQ

**Will other networks be added?**
To be confirmed before publication. The current system is built specifically for Base.

**Can I sweep NFTs?**
No. DustSweep handles ERC-20 tokens only.

**Can I choose a custom output token?**
Not currently — outputs are limited to ETH, USDC, WETH, and USDT for
