Project Overview
At the base of Fluid lies the Liquidity Layer, which serves as the foundation upon which other protocols can be built. This layer serves as a central hub where liquidity from all protocols is consolidated. It facilitates automated limits for protocols, manages utilization rates, and can deploy various rate models. The Liquidity Layer allows protocols to deposit, withdraw, borrow, and payback. End-users interact with the protocols, which in turn interact with the Liquidity layer.
Sui Hashi Testnet Handles Over 1.1 Million Bitcoin Deposits in Three Weeks, 25 Institutions Participate in Stress Testing
Odaily News: Since the launch of Sui's Hashi Bitcoin lending protocol testnet on July 22, it has processed over 1.1 million Bitcoin deposits and 165,000 withdrawals within three weeks. As of last week, more than 25 institutions had participated in the system's stress testing. Participating institutions include digital asset custodian BitGo, trading firm Cumberland, as well as Swissborg, Fluid, and Ledger, covering areas such as trading, custody infrastructure, and wealth management platforms. Hashi allows users to deposit native Bitcoin, which is confirmed by Sui validators before minting hBTC for on-chain lending and stablecoin borrowing. Deposits utilize a 2-of-2 multi-signature mechanism with MPC validator signatures, while withdrawals require review by the Guardian Layer; the project team will proceed with the 2026 mainnet launch only after this security layer completes its security audit.

Uniswap v4 Aggregation Feature Goes Live, Aggregator Hooks Can Wrap External Liquidity as v4 Pools
Uniswap Labs has announced the launch of Aggregator Hooks, bringing aggregation capabilities to Uniswap v4. The mechanism uses Hooks to wrap external liquidity sources as v4 pools and is now live on the Uniswap web app and API, covering Ethereum mainnet, Base, and Robinhood Chain. On the first day, it supports 7 external sources including Curve, Fluid, and PancakeSwap, with more networks to be added gradually. Per-block routing will fetch the latest quotes from integrated sources, build the optimal path between Uniswap pools and external sources, and settle within a single transaction without requiring new approvals; the related swaps will incur a protocol fee, which will be used for UNI burning.
