There have been quite a few happenings in the crypto world these days. A compliant platform and a banking system are at odds over the draft crypto regulation, each side sticking to their own stance; Polymarket was found to have a liquidity vulnerability, and someone arbitraged during the weekend when trading was light; WalletConnect launched a new stablecoin payment service based on the POS mechanism, aiming to expand application scenarios; Hyperliquid's recent revenue has declined somewhat, but its daily income remains stable at the million-level; Sonic's situation is a bit awkward—unclaimed airdrops were actively destroyed by passersby, mainly because the contract permissions were not properly controlled, which also serves as a reminder that project teams should not overlook the details. Looking at all these issues, there are market mechanism flaws, product innovation attempts, and technical risk cases.
