Summary

DustSweeper (🧹,🧹) allows users to swap small balance tokens (”dust”) for ETH without expensive gas transactions. Users just have to approve() the tokens they’d like to sell, and “market taker” bots execute the swap.

Many Ethereum mainnet users have low-balance tokens (<$500) in their wallets from old trades, airdrops, and trying out apps back when gas was cheap. They’d like to sell these tokens for ETH to clean out these wallets but gas prices are prohibitively high for swapping on Uniswap/Sushi/etc.

Bounties
