On April 7th, Chaos Labs announced in a blog post that it will step down from its core contributor role in the Aave ecosystem after three years of involvement. The team cited a fundamental disagreement over its risk management approach, which has only widened as the protocol has evolved. Chaos Labs listed three key reasons for the decision: - Core contributor turnover that has drastically increased operational pressure and risk - Aave V4 expanding the risk management scope—while also adding operational and legal burdens - Sustained operations at a loss, with profitability still challenging even after a budget increase The team noted that continuing on the current path would require either lowering execution standards or sustaining losses—neither of which is acceptable. This led to the decision to step down.

April 7 — On-chain prediction market platform Polymarket said Wednesday it will roll out its “largest infrastructure upgrade since launch” over the next 2–3 weeks, including a full redesign of its trading engine and the launch of its native stablecoin, Polymarket USD. The upgrade will introduce a brand-new CTF Exchange V2 smart contract system, optimize matching logic and order structure, boost matching efficiency, and cut gas costs. Additionally, Polymarket will upgrade its Central Limit Order Book (CLOB) to a hybrid model combining off-chain order matching and on-chain settlement. On the asset front, Polymarket will launch its native stablecoin Polymarket USD — pegged 1:1 to USDC — to replace the previous cross-chain USDC.e on Polygon, enhancing asset security and consistency. The platform will also support the EIP-1271 standard, allowing multisig wallets (like Safe) to trade directly — expanding use cases for institutions and advanced users. Polymarket noted existing ord

April 7 Bloomberg reports Binance’s compliance system has seen multiple personnel changes. Chief Compliance Officer Noah Perlman has discussed his departure with management, while several senior compliance executives overseeing sanction enforcement, financial crime monitoring, and investigations have also departed. Binance said the changes are part of “normal personnel turnover and performance management.” Notably, the exchange faces ongoing regulatory and public relations pressure: legislators and blockchain analytics firms are concerned its platform may have been used by Iran-linked accounts to evade U.S. sanctions. Binance added its compliance commitment “remains intact” and it is cooperating with regulatory agencies and law enforcement investigations.

April 7 — JPMorgan Chase CEO Jamie Dimon said in his latest shareholder letter that blockchain-based tokenization, stablecoins, and smart contracts are emerging as direct competitors to traditional banks, with the potential to fundamentally reshape core business models like payments, transactions, and asset management. He noted that a “whole new set of competitors” — including fintech firms and crypto-native institutions — are emerging. These players, with near-real-time settlement and direct asset transfer capabilities, could threaten banks’ fee income and deposit base. In response, JPMorgan is ramping up its own initiatives: expanding its blockchain division Kinexys (previously Onyx) and advancing its stablecoin project JPM Coin to compete with this new wave of financial infrastructure. Dimon emphasized that tokenization is a structural industry trend, not a cyclical shift. Additionally, he warned that geopolitical tensions, elevated asset prices, and global debt levels coul

Bitcoin briefly topped $70k on April 7, per HTX market data, and is now trading at $69,907 after retracing—with a 24-hour gain of 3.84%. ### Notes on American language habits applied: 1. **Conciseness**: Used "$70k" (common shorthand for $70,000) instead of the full "$70,000" (casual, widely used in U.S. financial news). 2. **Flow**: Swapped "according to" for "per" (more natural in quick news updates). 3. **Emphasis**: Placed the key price action ("briefly topped $70k") first, followed by context (date, data source) and current status. 4. **Punctuation**: Used an em dash to link the final gain detail (cleaner than a comma in fast-paced updates). No Chinese characters included, strictly English as requested.
