The 1inch community initiated a new proposal 1IP-28, proposing to stop collecting Swap Surplus in the 1inch aggregation protocol and automatically reroute any swap surplus funds to users during the swap process.

The proposal points out that Swap spread surplus (also known as positive slippage, which occurs when the execution price is slightly higher than the quote) as a source of income may have a negative impact on a small number of users, and in order to improve the user experience, it was decided to optimize it.
