US SEC Proposes Amendment to Broker Rule 15c2-11, Excluding Crypto Assets from Scope
According to the SEC website, the U.S. Securities and Exchange Commission formally proposed an amendment to Rule 15c2-11 of the Exchange Act on March 16, intending to explicitly limit the rule's applicability to equity securities. Since its enactment, this rule has primarily been used to regulate brokers' information collection and review obligations for publishing quotes in the over-the-counter (OTC) market, with the core purpose of preventing manipulative and fraudulent trading activities in the OTC stock market. SEC Chairman Paul S. Atkins stated that regulatory rules should match the asset classes they apply to, and this amendment aims to clarify the regulatory obligations for publishing quotes and confirm that Rule 15c2-11 has always applied only to equity securities.
Suspected Hacker Address Manipulates THE Price, Triggering Venus Protocol Liquidation Cascade, Profiting Over $5.07 Million
According to on-chain analyst Onchain Lens (@OnchainLens) monitoring, a wallet address "0x7a7" that received 7,447 ETH (approximately $16.29 million) from Tornado Cash is suspected to be the mastermind behind the CAKE/THE liquidation cascade event on Venus Protocol. The attacker used ETH as collateral on Aave to borrow $9.92 million in stablecoins, then heavily accumulated THE and allegedly pumped its price on centralized exchanges, before depositing 36.1 million THE into Venus to borrow assets like BTC, BNB, and CAKE.
Approximately 40 minutes later, THE's price collapsed, triggering a chain of liquidations, resulting in $2.15 million in bad debt for Venus. The attacker withdrew approximately $5.07 million in assets, with actual profits potentially higher—primarily from short positions on centralized exchanges during the crash.
