Zama protocol founder Rand posted on the X platform that, with the assistance of on-chain detective ZachXBT, the root cause of the cUSDC contract freeze has been identified. This freeze was caused by a court-issued injunction against addresses related to the Overnight Finance hacker, which had deposited approximately $12.5 million USDC into the cUSDC contract, accounting for over 99% of the funds within the contract, leading to the entire contract being frozen.Rand emphasized that this freeze is unrelated to the protocol itself or privacy technology, and it is not a sanction against Zama, but rather a typical DeFi judicial restriction scenario. The project adheres to compliance and privacy principles, not confusing the parties involved in transactions, only hiding balances and amounts. Currently, Zama is communicating with multiple parties to advance a resolution, has suspended the cUSDC, cUSDT, and cWETH contracts, and will restore them after completing the investigation and handling of the involved addresses, and will release a detailed review report as soon as possible.

Zama's official response to Circle's freezing of the cUSDC contract event states that Circle's compliance system flagged a wallet belonging to an external depositor. Since this wallet holds funds in the cUSDC contract, the entire contract was automatically swept into a standard holding freeze. This is merely incidental damage and not a sanction against the Zama Protocol. The Zama legal team has intervened and is isolating the flagged address, and will restore access for all unaffected participants as soon as possible.

ZachXBT stated that approximately $12.4 million in funds in the Zama cUSDC contract, which was blacklisted by Circle, may be associated with the DeFi project Overnight Finance, which has recently been embroiled in controversy due to accusations against its team of a Rug Pull.

"On-chain detective" ZachXBT posted that the stablecoin issuer Circle blacklisted the privacy protocol Zama's Confidential USDC (cUSDC) contract on Ethereum about 7 hours ago, resulting in approximately 12.6 million USDC being frozen within the contract.ZachXBT stated that the cUSDC contract has been publicly labeled in both Zama's official documentation and blockchain explorers. The specific reason for Circle freezing the related USDC is currently unclear. ZachXBT also pointed out that it had disclosed in March 2026 that Circle froze over 16 hot wallet addresses belonging to enterprises, protocols, and service providers without providing transparent explanations.

Circle released a quantum security white paper, proposing a phased upgrade plan covering Arc, USDC, smart contracts, and the validator system to address potential security risks posed by future quantum computing.

The crypto market maker Keyrock, in collaboration with Coinbase, Tempo, and Virtuals Protocol, released the report "Who Pays the Agent?" which states that AI Agents are rapidly becoming important participants in the on-chain economy. Data shows that from May 2025 to April 2026, AI Agents have completed approximately 176 million on-chain transactions, with a total settlement amount exceeding $73 million. The report points out that the average payment amount per transaction for AI Agents is only between $0.31 and $0.48, indicating that a machine-native micropayment economy is forming. About 76% of the transaction amounts are below the Visa fixed fee threshold of $0.30, making it difficult for traditional bank cards and banking payment systems to adapt to the high-frequency, small, autonomous payment needs of AI.Data shows that 98.6% of AI Agent payments are settled in USDC. As of Q1 2026, more than 104,000 AI Agents have completed registration. The report states that on the Base network, the cost of a USDC transfer is about $0.0001, accounting for approximately 0.03% of the $0.31 transaction amount, which presents a significant cost advantage compared to traditional payment systems. The report believes that stablecoins are gradually becoming the "default currency infrastructure" for economic activities between AI and machines. However, Keyrock also warns that the current AI payment ecosystem's high dependence on USDC poses a centralization risk, meaning that the entire emerging AI payment system largely relies on the regulation and infrastructure stability of a single stablecoin issuer.In addition, several technology and payment companies have begun to lay out AI Agent payment infrastructure, including the x402 protocol launched by Coinbase, the Machine Payments Protocol (MPP) launched by Stripe and Tempo, Google's AP2 delegated payment system, and Visa's expanded tokenized payment voucher service. The report also points out that the current regulatory frameworks, including the European MiCA Act, the U.S. GENIUS Act, and the EU AI Act, still lack comprehensive regulatory standards for autonomous financial transactions and payment behaviors between machines.
