Circle Freezes $12.6M in Zama Confidential USDC Contract

Circle blacklisted the smart contract address powering Zama's confidential USDC (cUSDC) wrapper on Ethereum at 01:08 UTC today, freezing approximately $12.6 million in user funds. The action stems from a court order tied to a civil lawsuit against Overnight Finance, a DeFi yield protocol accused of treasury mismanagement. The problem: Zama's contract holds funds from many users, not just Overnight Finance. Any USDC deposited into the privacy wrapper for legitimate use is now locked. The freeze adds to a string of controversial Circle blacklistings in 2026, including the March incident where 16 unrelated wallets were frozen under a sealed civil case.

US Has Seized $1 Billion in Crypto From Iran

Treasury Secretary Scott Bessent said Washington has seized nearly $1 billion in Iran-linked cryptocurrency under Operation Economic Fury. Speaking at the Reagan National Economic Forum, Bessent said authorities "outright grabbed the wallets" as part of a broader campaign to cut Tehran's access to offshore funds. The updated figure builds on previous seizures totaling roughly $500 million through April. The operation, launched in March 2025, has targeted oil revenue channels, frozen bank accounts, and pressured foreign governments to isolate Iranian financial networks.

TrapDoor Attack Targets Solana, Sui, and Aptos Developer Wallets

Security researchers discovered a supply-chain campaign called TrapDoor that planted 34+ malicious packages across npm, PyPI, and Crates.io targeting crypto developers. The packages, disguised as developer utilities, were designed to steal SSH keys, wallet files, AWS credentials, and GitHub tokens. The attack specifically targets Solana, Sui, and Aptos ecosystems. Notably, researchers found the attackers abused AI configuration files like .cursorrules and CLAUDE.md with hidden instructions, aiming to hijack AI coding sessions to exfiltrate secrets. No confirmed victims or stolen funds have been reported. Affected registries have been notified.

Bitcoin ETF Outflows Hit $2.8B in Record 9-Day Streak

US spot bitcoin ETFs recorded their longest withdrawal streak since launching in January 2024: nine consecutive trading days of net outflows totaling $2.8 billion. Wednesday's single-day outflow of $733 million was the heaviest, driven mostly by $528 million leaving BlackRock's IBIT. Bitcoin is trading at $73,591, roughly 10% off recent highs and on track to close May negative, ending a two-month winning streak. CryptoQuant data suggests the drawdown reflects a shortage of new buyers rather than aggressive selling.
