Dust Tokens vs Spam Tokens on Ethereum
How to distinguish small legitimate balances from unsolicited or suspicious tokens.
Why this matters on Ethereum
Dust describes size; spam describes intent or origin. A tiny token can be legitimate, while a large unsolicited token can still be suspicious.
Ethereum is an EVM network and the base layer for a large ecosystem of tokens, applications and Layer 2 networks.
Ethereum uses EVM-style addresses and token contracts, which means the same address can hold balances on several EVM networks at once. A balance that is missing on Ethereum may simply be sitting on a different network.
Ethereum: what to pay attention to
- Security: Pay close attention to contract approvals, transaction details and the exact domain used to initiate a transaction.
- Assets and tokens: Verify the ERC-20 contract address and distinguish Ethereum-native assets from representations on other networks.
- Costs: Ethereum gas can make very small balance movements uneconomical, so compare total execution cost with the balance value.
A Ethereum checklist for this topic
- Treat unexpected tokens or links that appear in a Ethereum wallet as untrusted until verified.
- Review and revoke permissions you no longer use on Ethereum, especially unlimited approvals.
- Check the domain you are on before connecting a wallet for any Ethereum action.
- Send a small test amount first when an address or route on Ethereum is new to you.
Bridge from Ethereum
Ethereum gas can make very small balance movements uneconomical, so compare total execution cost with the balance value. On the Polygon side: confirm that the token is held on Polygon and verify its contract before moving or swapping it.
The bridge guide below is informational; any transaction depends on current network conditions and the route shown in the bridge interface.
