What to do with dust and leftover balances

Dust is a balance too small to spend economically: moving it costs more in fees than the balance is worth.

Why it accumulates

Rounding, change outputs, the tail of a swap, airdropped tokens nobody asked for. It is normal.

Options

• Leave it. It costs nothing to hold. If fees fall or the asset rises, it may become spendable.
• Consolidate on a cheap chain. Dust on a low fee network can often be swept for very little.
• Combine it with a real transfer. On chains with multiple inputs, spending dust alongside a larger amount adds only a little to the fee.

What to avoid

Services promising to convert dust at generous rates. The economics do not work, which means the money is coming from somewhere else. Also ignore unsolicited tokens that appear in your wallet: interacting with them is a common way to be drained.
