The decentralized exchange (DEX) aggregator 1inch has opened its shared liquidity protocol, Aqua, to users; the protocol currently supports 13 Ethereum Ethereum Virtual Machine (EVM)-compatible chains.The Aqua protocol allows liquidity providers to keep their assets in their own wallets and use a single balance to maintain multiple positions, without having to spread their funds across different pools.This move aims to address the issue of low liquidity utilization; a study commissioned by 1inch previously found that, in the first half of 2026, 85% of the $1.84 billion in liquidity tracked by major centralized liquidity exchanges was underutilized.To encourage adoption, the 1inch Foundation has committed 10 million 1INCH tokens, and the 1inch DAO has contributed an additional $500,000 in USDC, jointly launching a three-month liquidity incentive program with a total value of approximately $1.37 million.
