"The liquidity provisioning space is broken, but you only see how broken once there's an alternative." — Sergej Kunz, Co-founder, 1inch
Eighty-five percent of concentrated liquidity deployed across major decentralized exchanges sat underutilized during the first half of 2026, according to on-chain research by Dune Analytics commissioned by 1inch. Of the $1.84 billion tracked across Uniswap v3, Uniswap v4, PancakeSwap v3, and Aerodrome Slipstream on seven chains, approximately $1.6 billion generated suboptimal returns. An average of $542 million per week sat fully outside active trading ranges, earning zero fees — an estimated $150 million in annual revenue foregone by liquidity providers.
On July 28, 1inch launched Aqua publicly across 13 EVM chains, eight months after a developer-only release. Aqua replaces the automated market maker (AMM) pool model with a registry-based system where tokens remain in provider wallets until a swap executes atomically. Uniswap, meanwhile, has deployed its v4 DualPool hook with a $150 million Spark stablecoin migration. This report compares the two architectural approaches to the same $1.6 billion problem and examines whether either model delivers measurable capital efficiency gains.
The Dune Analytics study, covering weekly snapshots from January 6 to June 30, 2026, quantified a structural inefficiency in concentrated liquidity markets. The out-of-range share of liquidity fluctuated between 25% and 35% throughout H1, spiking to nearly 41% in early February during a period of sustained directional price movement.
Three findings stand out:
Position size correlates inversely with utilization. 54% of liquidity in positions below $1,000 was out of range, versus 26% for positions above $1 million. However, positions exceeding $1 million held 47% of the total idle capital — approximately $260 million — because large positions dominate total value.
Manual wallets are the primary source of idle capital. Individual wallets accounted for 82% to 94% of attributed idle capital on Uniswap v3 depending on the chain. On Ethereum, 94% of idle capital came from individual wallets. Contract-managed positions (automated vaults and rebalancers) maintained more consistent ranges, with only 6.5% of their positions falling out of range versus approximately 30% for manual wallets.
Over $200 million remained unrepositioned for 90 or more days. This stale capital suggests a significant share of liquidity providers deploy once and abandon positions, collecting no fees while remaining exposed to impermanent loss.
According to Filippo Armani, research lead at Dune: "Decentralized exchanges have grown into one of the deepest, most liquid markets in crypto. What our research shows is that it has reached this scale even though much of its liquidity is not yet fully at work."
The determining factor for capital going idle was not market volatility per se but sustained directional price movement. A consistent move in one direction pushes more capital out of range than an intense but transient fluctuation.
Aqua represents an architectural departure from pool-based AMMs. Rather than depositing tokens into a smart contract, providers approve a token balance in their wallet and create positions that draw on that approved balance. The protocol maintains internal accounting counters — virtual balances — rather than holding actual tokens. When a swap matches a position's terms, Aqua pulls the required tokens and returns proceeds and fees in a single atomic transaction.
Key specifications:
The Shared Liquidity Ratio (SLR) allows one real wallet balance to simultaneously back multiple positions. A $100,000 balance can support three positions quoting a combined $300,000 in liquidity. This is not leverage — exposure is capped at actual wallet holdings. The model exploits the statistical property that asynchronous swap demand rarely requires all positions to fill simultaneously.
Counterparty restriction: At launch, swap execution is limited to verified 1inch Resolvers holding soulbound KycNFT tokens. This "verified counterparty" requirement prevents just-in-time (JIT) fee-sniping attacks, which 1inch claims erode up to 44% of provider fee income in traditional AMM pools.
Curve flexibility: Aqua's SwapVM supports multiple curve types — constant product, concentrated liquidity, and pegged stablecoin curves — while enabling custom developer logic. Providers retain full asset control and can revoke allowances or close positions at any time without unlock periods.
Uniswap's approach accepts that idle liquidity is inevitable and instead makes it productive. The DualPool hook, built for Uniswap v4 and now audited and open-sourced, routes idle stablecoin liquidity into Spark's yield-bearing ERC-4626 vaults while keeping that capital available to return to the pool when needed for trade execution.
Key specifications:
Uniswap v4 reached $1 billion TVL within 177 days of its January 30, 2026 mainnet launch. By end of Q1 2026, v4 pools had attracted over $4 billion in TVL and processed roughly 20% of all DEX volume on Ethereum mainnet. As of June 2026, cumulative settled volume stood at approximately $355 billion, with LPs earning over $260 million in cumulative swap fees across 4,689 tracked pools.
Despite these metrics, the v4 architecture has not eliminated the idle capital problem. Approximately 30.5% of v4 liquidity remained out of range per the Dune study, and only 10% of total value locked was utilizing hooks — the very mechanism designed to improve capital efficiency.

The fundamental philosophical difference: Aqua attempts to solve the idle capital problem by never locking capital in the first place. DualPool acknowledges that locked capital will be idle and redirects it to external yield. These are complementary rather than competing strategies — a protocol could theoretically adopt both.
Both launches occur against a contracting DeFi market. Total DeFi TVL has fallen 37% in 2026 to $71.77 billion as of June, retreating from $114.49 billion at the start of the year. Ethereum holds 53.1% of DeFi TVL at $38.24 billion. Daily DEX volume reached $7.20 billion on June 18, rising 9.3% day-over-day even as locked capital fell — suggesting higher velocity per unit of TVL.
The DEX aggregator market where 1inch operates remains volatile. 1inch's market share fell from 25.2% in Q4 2025 to 17.0% in Q1 2026, dropping from first to fourth place. It then recovered to approximately 60% market share in May 2026 after expanding to Solana, before settling around 30% by mid-2026. CoW Swap held approximately 22% of Ethereum DEX aggregator market share as of April 2026, with KyberSwap at approximately 30%.
Uniswap v4 is processing roughly 20% of Ethereum mainnet DEX volume with an average pool APY of 56.43% across its 4,689 tracked pools. These figures suggest that while v4 adoption has been meaningful, the majority of DEX volume still routes through other venues — including aggregators like 1inch's Fusion network that sit atop Uniswap's own pools.
Stablecoin circulating supply hit $314 billion in mid-June 2026, approximately 4.4 times total DeFi TVL. This gap — $314 billion in stablecoin float versus $72 billion locked in DeFi — represents the capital efficiency opportunity both architectures are targeting.
Aqua risks:
DualPool risks:
Shared risk: Both models depend on sufficient trading volume to generate fees. In a market where DeFi TVL has fallen 37% in six months, fee revenue compression may limit the returns from improved capital efficiency.
The DeFi liquidity efficiency problem is well-quantified: $1.6 billion underutilized, $150 million in annual fees left on the table, and over $200 million sitting unrepositioned for 90+ days. The two most significant architectural responses — 1inch Aqua's registry-based wallet-native model and Uniswap v4's yield-routing DualPool hook — embody different assumptions about capital behavior. Aqua bets that providers will prefer keeping assets in their wallets. DualPool bets that pool-locked assets should earn yield between trades.
Neither approach has yet demonstrated impact at scale. Aqua launched publicly on July 28 with a $1.37 million incentive program and no disclosed volume history. DualPool has $150 million deployed but only 10% of v4 TVL uses hooks. The market will determine which architecture — or what combination — ultimately moves the needle on the $542 million sitting idle each week. What is measurable today is the cost of inaction: $150 million per year in fees that providers cannot collect.
