1inch has introduced Aqua, a new liquidity protocol designed to enable decentralized finance (DeFi) applications to share liquidity pools across various strategies without compromising asset custody. The protocol allows funds to remain in users' wallets, only being utilized during trade execution. This innovation facilitates multiple trading strategies from a single wallet, enhancing flexibility for liquidity providers. Developers can access Aqua's software development kit, code repository, and technical documentation on GitHub, with a full front-end interface expected by early 2026. Aqua's "shared liquidity layer" supports strategies like Automated Market Makers, stablecoin exchange pools, and custom logic strategies, each governed by independent rules and tracked by Aqua's accounting system.
