Why dust exists and why it stays small
Tiny residual amounts can occur during swap/liquidity operations due to on-chain math and rounding.
EZManager's RebalancePlanner contract is built to calculate exact theoretically optimal swap amounts on chain, keeping this residual dust extremely small.
How EZManager handles dust
Dust is tracked with your position lifecycle instead of becoming confusing wallet-level accounting noise.
At exit, tracked dust is returned so you do not have to manually chase or reconcile tiny leftovers.
