1inch launches the shared liquidity protocol Aqua, enabling a single fund to support multiple DeFi liquidity positions

According to official news, the decentralized exchange aggregator 1inch has officially launched the shared liquidity protocol Aqua for all users. Aqua allows users to support multiple liquidity positions simultaneously with just a token balance, without the need to deposit assets into a liquidity pool. The assets remain in the user's wallet, and only when a transaction is actually executed does the protocol call the corresponding tokens from the wallet through a single atomic transaction to complete the settlement, returning the received tokens and fees to the wallet.1inch stated that this new model, known as "shared liquidity," is expected to address current issues in DeFi liquidity, such as long-term idle liquidity, low capital utilization, and asset custody risks. The protocol was opened to developers last November and is now officially launched for all users, supporting 13 EVM-compatible chains including Ethereum, Arbitrum, Base, Robinhood Chain, and BNB Chain.1inch indicated that there are several structural issues with current DeFi liquidity. Although many protocols have a high total value locked (TVL), a large amount of liquidity remains in inactive price ranges for extended periods, failing to earn trading fee revenue while also bearing market volatility risks. Additionally, liquidity providers (LPs) typically need to split limited funds across different protocols, trading pairs, and price ranges, leading to decreased capital utilization. Furthermore, traditional models require users to deposit assets into liquidity pools, which not only loses other uses of the assets but also means relinquishing asset custody rights and facing risks such as JIT (Just-In-Time) liquidity bots seizing fees. Aqua enhances capital efficiency by registering wallet balances as a shared liquidity source, allowing the same asset to support multiple liquidity positions without transferring asset ownership; when the wallet balance is insufficient to cover a transaction, the protocol will not execute that transaction, thus keeping the user's actual risk always limited by the wallet holdings.

IMF: Brazil's cross-border cryptocurrency fund flow has surpassed traditional capital flows

The International Monetary Fund (IMF) stated in its financial system stability assessment report released this month that Brazil's cross-border capital flows based on cryptocurrency have continued to grow since 2017, surpassing traditional capital flows. The report indicates that these capital flows are mostly driven by stablecoins, as businesses and retail investors use stablecoins for efficiency and tax-related reasons. The flow of stablecoins is related to international and local investment indicators such as the S&P 500, VIX, and Bitcoin prices, and is also influenced by exchange rates, interest rates, policy uncertainty, and changes in tax policies.The IMF noted that the Central Bank of Brazil has taken measures to regulate the virtual asset service provider (VASP) industry, but there are still shortcomings in areas such as customer legal protection and asset segregation. Comprehensive implementation of international standards such as the travel rule for anti-money laundering and combating the financing of terrorism (AML/CFT) is still needed. The report pointed out that Brazil's cryptocurrency system is connected to the traditional financial system, and regulators need to cooperate with domestic and international regulatory bodies to establish a more robust reporting mechanism. The Brazilian Congress is preparing to review Bill 4308/2024 to regulate the status of stablecoins.
