Cách đây vài giờ, Circle lặng lẽ đưa hợp đồng cUSDC của Zama vào danh sách đen USDC.
🔰 $12.6 triệu trong tiền gửi của người dùng. Bị đóng băng ngay lập tức
Zama là một giao thức thanh toán bảo mật trên Ethereum. Hợp đồng cUSDC của nó cho phép người dùng giữ và chuyển USDC một cách riêng tư. Circle đã đưa toàn bộ hợp đồng vào danh sách đen chỉ trong một bước.
Nguyên nhân không phải là một cuộc tấn công. Đó là một vụ kiện dân sự của Mỹ.
🔰 ĐÂY LÀ CHUỖI SỰ KIỆN
🔹 Vào ngày 11 tháng 5, một ví liên kết với Overnight Finance đã gửi $12.4 triệu vào Zama.
🔹 Overnight Finance đang bị kiện bởi chính những người nắm giữ token của họ, những người cáo buộc rằng đội ngũ đang dần đóng cửa giao thức để có lợi cho những người trong cuộc.

Circle Freezes $12.6M in Confidential USDC: Is the Privacy Narrative in Jeopardy?
The delicate balance between decentralization and regulatory compliance just faced a massive reality check. In a precedent-setting move, stablecoin giant Circle officially blacklisted a major privacy-centric smart contract on Ethereum, freezing roughly $12.6 million in user funds.
The targeted contract belongs to Zama’s Confidential USDC (cUSDC) protocol—an experimental, highly-watched network that uses Fully Homomorphic Encryption (FHE) to shield user transaction amounts and balances on public blockchains.
The sudden freeze has reignited an explosive debate across the Web3 ecosystem: Can true privacy exist on-chain when the underlying liquidity is entirely centralized?
The Backdrop: What Triggered the Freeze?
While Circle has not issued an official public statement explaining the blacklist, on-chain sleuth ZachXBT quickly mapped the digital paper trail.
According to blockchain data, the freezing mechanism was likely triggered by internal drama surrounding a separate protocol, Overnight Finance.
A wallet linked to Overnight Finance deposited $12.4 million into Zama’s privacy protocol.This deposit occurred amidst a hostile Snapshot governance dispute, where community token holders accused the project's team of orchestrating a potential treasury rug pull.
To mitigate bad actor movement or comply with pending legal directives, Circle deployed its built-in smart contract blacklist. However, because the funds were deposited directly into Zama's FHE privacy pool, the corporate giant didn't just freeze the alleged bad actor's funds—they froze the entire contract proxy, pooling together and trapping innocent Zama users in the crossfire.
Why This Matters for the Crypto Market
This isn’t the first time an asset issuer has pulled the plug. We saw similar widespread actions during the Tornado Cash sanctions. However, the Zama freeze introduces a dangerous new precedent for advanced cryptographic privacy (like FHE and Zero-Knowledge tech).
1. The "Commingling" Trap
When users deposit funds into a privacy pool, their liquidity is mathematically bundled together to obscure transaction origins. If centralized issuers decide that interacting with contaminated or disputed funds justifies freezing the entire protocol infrastructure, any protocol offering transaction anonymity becomes a ticking time bomb for liquidity providers.
2. The Fallacy of "DeFi" Stablecoins
This serves as a stark reminder that while a dApp might be deployed on a decentralized network like Ethereum, the lifeblood inside it (USDC, USDT) is entirely corporate-controlled. A single private key entity can revoke access to millions of dollars with a line of code.
Key Takeaways for Traders & Yield Farmers
If you are interacting with cutting-edge privacy layers, FHE protocols, or algorithmic yield aggregators experiencing internal governance crises, the risks have shifted significantly:
Watch Treasury Governance: Keep a very close eye on the governance forums of the protocols you yield-farm. If a project enters a "rug pull" dispute or faces severe internal fracture, remove your liquidity immediately before centralized emergency protocols take over.Expect a Pivot to Decentralized Stablecoins: Events like this heavily reinforce the macro trend toward decentralized, over-collateralized stablecoins (like Ethena’s USDe or LUSD) within privacy-centric protocols to completely avoid censorship vectors.
What’s your take? Is Circle justified in stepping in to halt suspected treasury exploits, or does this unilateral freezing power completely destroy the ethos of Web3? Let’s talk in the comments!
