1Inch Aims to Reduce Gas Fees With V3

Version 3 of the 1Inch DEX Aggregation Protocol is launching with a focus on facilitating lower gas fees.

1Inch v3 has aimed to optimize its assembly code to reduce gas fees applying to swaps using Uniswap v2 and its forks. The new version is also designed to use traditional splits across several paths if those swap deals end up being more efficient.

Users will still be able to use v2, which 1Inch plans to support for the immediate future, but v3 will be the default. 1Inch v3 will require new approvals for each asset, which will result in additional upfront gas costs in order to access the decreased gas fees moving forward.
