1inch has launched Aqua, a shared liquidity model aimed at addressing fragmentation in decentralized finance (DeFi). The protocol was revealed during Devconnect in Argentina and includes a software development kit (SDK), libraries, and documentation for developers. 1inch is offering bounties up to $100,000 to encourage contributions to Aqua’s development. This model allows users to maintain self-custody of their assets while improving capital efficiency by turning each wallet into a self-custodial Automated Market Maker. This approach eliminates the need for users to deposit capital into various pools, potentially doubling or tripling liquidity effectiveness. The 1inch platform already supports over 26 million users and processes more than $500 million in daily trading volume, primarily through its decentralized exchange (DEX) aggregation engine. Aqua is positioned as a foundational element for capital-efficient DeFi, building on the team's past work in aggregation. The launch follows various integrations, including a partnership with Coinbase to enhance token swaps and the introduction of cross-chain swaps between Solana and Ethereum Virtual Machine (EVM) networks. These developments solidify 1inch's status as the second-largest DEX aggregator on Ethereum by market share.
