Scanning & Selecting Tokens

When you connect, DustSweep scans your whole wallet on Base — every token you hold, not just a curated list — then sorts the results so you can choose what to sweep with confidence.

​
How the scan works

  1. Full balance discovery. DustSweep fetches every non-zero ERC-20 balance at your address using a blockchain indexer. No token list limits what it can find.
  2. Pricing. Each token is priced using live market data (DexScreener, with CoinGecko as a fallback), including liquidity depth and the best DEX for that token.
  3. Classification. Every token is risk-checked and sorted into a bucket (see below).
  4. Result. Sweepable tokens appear in the selection list, sorted by USD value. The rest are grouped with their reasons.
The scan usually takes a few seconds; results are briefly cached, so repeated scans are fast. If a scan takes longer than 45 seconds it times out and you can refresh.

The buckets

Selecting tokens

You have three ways to build your selection:
  • Manual — tap each token you want to include.
  • Select all — adds every swappable token (up to the 50-token limit).
  • Auto-mode — automatically selects every token at or below a USD threshold you set (default $100). Useful for “sweep everything small, keep my real positions”.
Rules applied automatically:
  • Maximum 50 tokens per sweep.
  • Tokens matching your chosen output token are excluded (you cannot swap USDC into USDC).
  • Changing your selection, output token, or slippage refreshes the quote.
User Safety Note The scan shows what you hold; it never moves anything. Be deliberate with tokens in the suspicious group — they are hidden because they match known spam/scam patterns. You do not need to interact with a scam token to “get rid of it”; simply leaving it untouched is safe.

​
FAQ

The scan missed a token I know I hold. Refresh balances. If it still does not appear, it may have no price data yet — check the hidden group. Why is a token’s USD value slightly different from another site? Prices come from aggregated DEX market data and refresh continuously; small differences between sources are normal. Can I sweep my entire balance of a large token? Yes — selection is not limited to “dust”. Anything swappable can be included, at its full balance.
