Vacuum Finance ($VAC) will clean up your DUST on the Ethereum Mainnet and will turn it into ultrasound money ($ETH) on a Layer 2 (Arbitrum, Optimism) of your choice.

<mark style="color:blue;">**Monetise Dust**</mark>&#x20;

By letting Vacuum Finance swap & bridge your dust into ETH on L2 you are finally able to benefit from (long accumulated) dust.

<mark style="color:blue;">**Fund L2**</mark>&#x20;

Use your main chain dust balances to fund a Layer 2 of your choice without worrying about expensive bridges.

<mark style="color:blue;">**State Bloat Reduction**</mark>&#x20;

Ethereum State bloat kills. We aim to reduce it.
