The upgrade also claims to protect users against maximum extractable value (MEV), which refers to a common type of front-running prevalent on blockchains.
“Fusion makes swaps on 1inch dramatically more cost-efficient, as users won’t have to pay network fees, plus, an extra layer of security is added, protecting users from sandwich attacks,” 1inch Network co-founder Sergej Kunz said.
1inch is a project that lets traders access liquidity from multiple DEXs in order to swap tokens from within a single platform. It leads in the DEX aggregation niche, processing over $1 billion in trading volume within the past week alone, ahead of competitors like Paraswap, Matcha and Cowswap.
The Fusion upgrade relates to 1inch's Swap Engine, a mechanism that connects users with professional market makers that serve liquidity requirements.
