1inch, a decentralized exchange (DEX) aggregator, has opened Aqua, a shared liquidity protocol that allows liquidity providers to use the same wallet balance across multiple positions instead of splitting assets among separate pools. The protocol launched across 13 Ethereum Virtual Machine-compatible blockchains on July 28, 2026, with a $1.37 million incentive program designed to attract early participants.

What Problem Does Aqua Actually Solve?

The DeFi lending and trading ecosystem has a capital efficiency problem. Research commissioned by 1inch found that 85% of $1.84 billion tracked across major concentrated-liquidity exchanges was underutilized in the first half of 2026. On an average week, roughly $542 million sat completely outside active trading ranges, causing liquidity providers to miss an estimated $150 million in annual fees. Aqua addresses this by letting tokens remain in a provider's wallet under their control while one balance backs multiple positions across different strategies.

To illustrate the efficiency gain, 1inch provided a concrete example: a $100,000 balance could support three positions quoting a combined $300,000 in liquidity. This is quoted liquidity rather than additional capital, meaning orders can only execute against assets actually held in the wallet. If the balance cannot cover a swap, the transaction fails.

How Does Aqua Work Across Multiple Blockchains?

Aqua is now live on a diverse set of networks, expanding beyond its initial launch. The protocol supports positions across multiple blockchain environments, including:

• Major Layer 1 Networks: Ethereum, the primary blockchain for DeFi applications
• Layer 2 Scaling Solutions: Base, Arbitrum, and other EVM-compatible chains designed to reduce transaction costs
• Alternative Blockchains: BNB Chain, a high-throughput network, and Robinhood Chain, a newer entrant to the DeFi ecosystem

Users can create full-range positions, concentrated positions (which focus liquidity in a specific price range), or pegged positions (which maintain a fixed ratio between two assets) across these chains. The protocol underwent eight independent security audits before launch, though liquidity providers still face risks including price movements, impermanent loss (a temporary loss that occurs when asset prices diverge), and smart-contract vulnerabilities.

What Incentives Are Driving Early Adoption?

To bootstrap liquidity and attract early participants, 1inch is running a three-month incentive program distributed through Merkl, a rewards management platform. The 1inch Foundation committed 10 million 1INCH tokens, valued at approximately $870,000 at current prices, while the 1inch DAO (decentralized autonomous organization) added $500,000 in USDC stablecoin, bringing the total program to roughly $1.37 million.

"Tokens to stay in your wallet, under your control, while one balance backs multiple positions across different strategies rather than being split between smart contract deposits," said Sergej Kunz, co-founder of 1inch.

This incentive structure is designed to test whether Aqua can retain liquidity providers over time and whether the protocol's efficiency gains translate into sustained usage. The rollout follows 1inch's initial unveiling of Aqua last year, which included software development kits, libraries, and documentation for developers building on the protocol.

Why Does This Matter for DeFi's Future?

The launch of Aqua reflects a broader shift in DeFi toward capital efficiency and better tools for liquidity providers. For years, concentrated-liquidity protocols like Uniswap V3 have allowed providers to earn higher fees by focusing their capital in specific price ranges, but this requires active management and splits capital across multiple positions. Aqua's approach of using a single balance to back multiple positions could reduce friction and make concentrated liquidity more accessible to retail participants who lack sophisticated portfolio management tools.

The $150 million in annual missed fees identified by 1inch's research suggests significant room for improvement in how DeFi protocols allocate capital. If Aqua can capture even a fraction of that underutilized liquidity, it could meaningfully increase fee generation for providers and improve price discovery and execution quality for traders across multiple blockchains.
