1inch opens Aqua, where one wallet's capital quotes many pools
The aggregator's shared liquidity layer went public across 13 chains, letting providers back several positions with the same tokens without depositing them anywhere—a capital-efficiency claim that doubles as a settlement question.
What happened
1inch opened Aqua to the public on 28 July across 13 EVM networks including Ethereum, Arbitrum, Base and BNB Chain. Instead of locking assets in pools, providers authorise the protocol against tokens that stay in their own wallets, and the same capital can stand behind several positions at once—the release's example has $100,000 supporting up to $300,000 of quoted liquidity across three positions. The 1inch Foundation has allocated 10 million 1INCH to provider rewards, with a further 500,000 USDC proposed and pending governance approval. The protocol went through eight independent audits, including OpenZeppelin and Nethermind, according to the release.
Why it matters
Concentrated-liquidity AMMs leave most deposited capital idle—research commissioned by 1inch puts underutilisation across major venues near 85% in the first half of 2026, a figure that is the vendor's own. Aqua's answer is to let quoted liquidity exceed the capital behind it, which is how dealers have always worked but is new as a shared DeFi primitive. If it holds, the economics of market making on chain shift from pool rents towards balance-sheet efficiency; it also lands 1inch in the same design contest as Uniswap's v4 hooks over what an AMM position actually is.
What is not settled
Whether liquidity quoted several times over is reliably there when trades demand it, especially under stress, is the design's central untested claim. The utilisation figure that motivates the launch is commissioned rather than independent, and the reward budget means early volumes will not show whether the model stands without subsidy. Coverage beyond the wire was thin on launch day—The Block's report is the substantial independent account—so the depth of provider take-up is not yet observable from outside.

Runs the competing answer to the same question through v4 hooks, where the pool stays the unit and customisation happens around it, which is the comparison a shared-balance design invites.
