1inch launches Aqua publicly, a shared liquidity layer for DeFi across 13 chains
1inch (1inch) opened its Aqua liquidity layer to the public on Tuesday, moving the product out of the developer-only mode it had run in since November and pitching it as an alternative to the pool-based model that underpins most decentralized exchanges.
Aqua is a self-custodial system that lets liquidity providers back multiple trading positions from a single wallet balance without depositing tokens into a pool, according to 1inch.
The protocol works as a registry, meaning: a provider connects a wallet and approves a token balance, and Aqua pulls the requested tokens only when a swap order matches a position, settling the trade and fees in one atomic transaction. Otherwise, the tokens stay in the wallet, according to the team.
1inch describes Aqua as one of the first risk-controlled alternatives to the traditional pool structure. The mechanism caps a provider's exposure at the tokens actually held rather than the combined size of every position opened, and a wallet that cannot cover a swap simply is not called on.
The same balance can support several quotes at once, the protocol stated. 1inch said a $100,000 balance could back three positions collectively quoting $300,000 in liquidity, with nothing borrowed and every swap executing only against assets held in the wallet.
Alongside the launch, 1inch went live with a liquidity reward program delivered through Merkl and led by Degensoft. The 1inch Foundation committed 10 million 1INCH in provider rewards. A further 500,000 USDC from the 1inch DAO is proposed on top of that, subject to approval through a governance vote.
Limited DeFi LP model
1inch argues that the current pool model limits DeFi's ability to scale and draw traditional capital on-chain, because depositing into pools means surrendering custody while active capital thins out across protocols and price ranges.
Onchain research by Dune, commissioned by 1inch, found that roughly 85% of concentrated liquidity across major decentralized exchanges was underutilized in the first half of 2026. This figure represents about $1.6 billion of the $1.84 billion tracked.
The same study, measured a different way, put the mean share of concentrated liquidity sitting outside the active trading range at 29.5% over 26 weeks, equal to about $542 million idle in an average week across four protocols.
Aqua went live across 13 EVM chains, including Ethereum, Arbitrum, Base, BNB Chain, and Robinhood Chain. The launch also carries a liquidity leaderboard, position visualizations, batch position creation, cross-chain provider profiles, and sub-wallets.
1inch said Aqua underwent eight independent security audits from firms including OpenZeppelin, Nethermind, Hexens, and Theori. The system is designed to never holds user tokens, and revocation halts new fills once it confirms on-chain, though providers still carry market and smart-contract risk, and swap fees are not guaranteed, according to 1inch.

Goldman Sachs believes that the AI investment cycle is currently in the "trough of disillusionment," but this is not the first time. The core contradiction lies in the fact that the business models of new cloud computing providers are highly dependent on end-user returns from AI spending, while currently "there are basically zero companies that can attribute profits to AI." Social Capital founder Palihapitiya has clearly defined an 18-month key window, during which the market will decide which AI business models are sustainable and which are not.
Anthropic's Core Concern: Revenue Can Be Withdrawn at Any Time, but Computing Power Costs Are Locked in for up to 20 Years
Zheshang Securities believes that Anthropic's revenue is mainly based on usage-based billing, with remaining performance obligations covering only about 5.1 months of annualized revenue, while compute power costs are already locked in with $895.4 billion in irrevocable commitments, some extending as far as 2045. Revenues can be reduced at any time, but costs are non-exitable, creating a highly asymmetric maturity gap between the two—this is the company's real core constraint.
Triple Pressure from the Federal Reserve, Treasury, and Congress; Goldman Sachs: Liquidity Crisis May Occur in 2027
Goldman Sachs warns that the reserve ratio of bank assets has dropped to around 11%, only slightly above the crisis trough of 2019. In the second half of 2027, a deadlock in debt ceiling negotiations will force the Treasury to rebuild the TGA, triggering a "perfect storm" of a sharp drop in reserves and a surge in T-bill supply; combined with stalled money market fund buying, this will create a huge liquidity black hole. The Federal Reserve could be forced into the awkward position of lowering interest rates and launching large-scale bond purchases to rescue the market.
