General FAQ

Quick answers to the most common DustSweep questions. Each answer links to the page with full detail.

​
Basics

What is DustSweep? A tool that converts many small token balances on Base into ETH, USDC, WETH, or USDT in one sweep. See What is DustSweep?. Which network does it support? Base mainnet (chain ID 8453) only. See Supported Network & Tokens. Is it custodial? No. Tokens move wallet → contract → DEX → wallet inside one atomic transaction; the contract holds nothing between transactions. See Non-Custodial Design & Approvals. What is the contract address? The active sweep router (DustSweep V3, DustSwapSweepRouter) on Base: 0x06e6BAa61A5Da1E4469FCa5dEa3EB68324255E20. Verify it on BaseScan.

​
Costs

What does a sweep cost? A 2% protocol fee taken from the output (hard-capped at 3% on-chain) plus Base gas — typically a few cents. See Fees. Is there a fee on failed or refunded tokens? No. Fee applies only to realized output; skipped tokens are refunded in full.

​
Limits & tokens

How many tokens per sweep? Up to 50 (smart-contract limit). Why can’t I sweep a certain token? No liquidity, no reliable price, value below $0.01, flagged as suspicious, or it is native ETH (wrap to WETH first). See Why Some Tokens Can’t Be Swept. Can I sweep WETH into native ETH? Not currently — that is an unwrap, not a swap. Sweep WETH to a stablecoin or unwrap it separately. What output tokens are available? ETH (default), USDC, WETH, USDT. See Choosing an Output Token.

​
Wallets & prompts

How many confirmations will I see? Batching wallets (Coinbase/Base Account, OKX): usually one. Others: one gas-free signature + one transaction, plus one-time exact approvals for new tokens. See Executing a Sweep. What exactly am I signing? A Permit2 message listing your exact tokens and amounts, the sweep contract as sole spender, a one-time nonce, a 30-minute expiry, and the full sweep plan (including the fee) frozen in a witness hash. See What You Sign and Why It’s Safe. Why does it say my address is “set up with another wallet”? Your account was upgraded (EIP-7702) by a different wallet; only that wallet can batch on it. Switch to it for one-click, or continue with Sign & Sweep. See EIP-7702 Explained. Does DustSweep ever ask for unlimited approvals? No. Exact amounts only, always. See Non-Custodial Design & Approvals.

​
During & after the sweep

What happens if one token’s swap fails? It is skipped and its full amount refunded to your wallet in the same transaction; the rest of the sweep completes. See After the Sweep. Why did I receive slightly less than quoted? Market movement within your slippage tolerance plus the 2% fee. Per-token minimums you accepted are always enforced. See Slippage & Price Impact. My quote expired. What now? Quotes last 30 minutes. Refresh and sweep with the new quote. Do sweeps earn rewards? Yes — sweeps count toward DustSwap points and quests (first sweep, 10+ tokens, $100+ value, and more).

​
Security

Is the contract audited? An internal AI-assisted security review has been completed (0 critical, 0 high findings); a further audit pass is planned and the published audit file will be updated. To be confirmed before publication: final audit artifacts. See Security Model. Can DustSweep drain my wallet? No mechanism for it exists: approvals are exact-amount and reset to zero, signatures are single-use and expiring, and only allowlisted DEXes can ever be called. What is the single most important safety habit? Verify you are on app.dustswap.wtf and read every wallet prompt against What the Wallet Prompts Mean.
