1inch Unveils Aqua Multichain Across 13 Networks with Incentive Program

1inch has expanded its shared liquidity system, allowing providers to support multiple positions using a single wallet balance. The protocol, called Aqua Multichain, is now available across 13 Ethereum Virtual Machine-compatible networks.

Aqua Multichain aims to reduce fragmentation and improve capital efficiency across decentralized markets by letting users quote several positions without splitting assets into separate pools. According to 1inch, a $100,000 balance could back three positions quoting a combined $300,000, representing quoted liquidity rather than additional capital.

The protocol's public interface lets users create full-range, concentrated or pegged positions across networks such as Ethereum, Base, BNB Chain, Arbitrum and Robinhood Chain. 1inch first introduced Aqua Multichain last year, releasing its SDK, libraries and documentation to developers ahead of the broader launch.

The rollout follows research commissioned by 1inch showing that 85% of $1.84 billion tracked across major concentrated-liquidity venues was underutilized during the first half of 2026. Roughly $542 million sat outside active trading ranges in an average week, missing an estimated $150 million in annual fees.

To support adoption, 1inch launched a liquidity incentive program distributed through Merkl, combining 10 million 1INCH and $500,000 in USDC over three months. At current prices, the token portion is valued around $870,000, bringing the combined program to roughly $1.37 million.

Security was a core focus for 1inch, with Aqua Multichain undergoing eight independent audits. Despite the design improvements, liquidity providers still face price volatility, impermanent loss, and smart-contract risk.
