Bitget Wallet announces that its crypto payment card, Bitget Wallet Card, has completed a major upgrade and will officially launch the "Assetback" mechanism on August 1, with the asset cashback rate simultaneously increased to 3%. This mechanism will be open to over 50 countries across Europe, Latin America, Africa, and the Asia-Pacific region. Cardholders can freely choose their preferred cashback assets, covering BTC, gold, tokenized US stocks (NVDA, TSLA, GOOGL, S&P 500), stablecoins, and more. The base asset cashback rate is 2%, while new users or users who reach the monthly spending threshold can unlock the 3% cashback tier. This upgrade breaks the traditional model where card swiping only returns cash/points, marking the transformation of Bitget Wallet Card services from consumption cashback to accumulation of appreciating assets. It turns daily consumption into an opportunity for RWA asset allocation, allowing users to achieve a new daily finance experience of "spend to build positions" without needing to open a brokerage account throughout the process or perform extra operations at checkout.
Taiko stated on its X platform that it has confirmed its chain state verification mechanism has been compromised, and the security assumptions of all cross-chain bridges deployed on Taiko are no longer reliable.Taiko said it is coordinating with its security committee and ecosystem partners to control the situation, suspending affected systems, and taking technical and legal actions. Taiko strongly advises all users to immediately withdraw funds from cross-chain bridges deployed on Taiko.Additionally, Taiko has made an urgent request for all centralized exchanges to suspend TAIKO token deposit services until further official notice. Previously, Taiko's ERC20 Vault was attacked, resulting in losses exceeding $1 million.
: HyperLiquid has announced an upgrade to the AQAv2 mechanism. The system will use on-chain automated trading to maintain a dynamic 1:9 balance of USDC between two core addresses in each HyperEVM block, corresponding to the contract execution layer and the treasury reserve layer, respectively.According to the mechanism design, this ratio is used for functional stratification between "high-frequency trading and liquidation liquidity" and "long-term reserves and yield pools," aiming to enhance system stability and isolate trading risks.On the technical side, the balancing process is executed automatically by the system without manual intervention. Circle is responsible for the technical deployment, while Coinbase undertakes the treasury deployment and management.Regarding the yield mechanism, AQAv2 stipulates that stablecoin issuers must distribute approximately 90% of their cost-adjusted reserve earnings generated within the Hyperliquid ecosystem to the protocol. Settlement occurs on a 30-day cumulative cycle, and the earnings will be automatically transferred to the Assistance Fund on the 8th day after the cycle ends.Additionally, the mechanism includes a transition period arrangement:1. Start of yield accrual: August 26;2. First yield payment: October 3.The market believes this design marks the evolution of stablecoins from traditional custody structures toward an on-chain infrastructure model characterized by "protocolized capital stratification + automated yield distribution."
