ZKsync Admin Wallet Hack Mints $5M in New ZK Tokens

ZKsync confirmed that a compromised admin key allowed an attacker to mint 111 million unclaimed ZK tokens, worth approximately $5 million. The exploit targeted the airdrop distribution contract and briefly increased the circulating supply by around 0.45%.

The attacker used a function designed to sweep unclaimed tokens, redirecting the assets to their wallet in a single transaction. ZKsync’s core protocol, token contract, and governance systems were not affected, and the exploit cannot be repeated.

The compromised wallet, now flagged by investigators, still holds most of the stolen funds and is under surveillance by exchanges and security firms. ZKsync has asked the attacker to return the funds voluntarily, warning of legal consequences.

"This is why ZK is the Endgame. Trust math, not operators," said ZKsync founder Alex Gluchowski, underscoring the need for decentralized security over human-controlled systems. Community concerns have surged over the risks tied to centralized control of token issuance.

Canada to Launch First Spot Solana ETFs

Canada is set to debut the world’s first spot Solana ETFs this Wednesday, according to a TD Bank circular shared by Bloomberg analyst Eric Balchunas. Four asset managers, Purpose, Evolve, CI, and 3iQ, received approval from the Ontario Securities Commission to launch the products. These ETFs will offer staking rewards, potentially providing higher yields than existing Ether staking products.

This puts Canada ahead of the US, where several firms like Grayscale and 21Shares are still waiting on regulatory green lights for similar Solana products. Meanwhile, the U.S. market only has Solana futures ETFs, which have drawn relatively low assets under management. The Canadian approval may serve as a test case for broader institutional demand for Solana exposure.

Ethena Labs Exits Germany After BaFin Pressure

Ethena Labs, the issuer of the synthetic stablecoin USDe, announced on April 15 that it is shutting down its German entity and withdrawing from MiCAR licensing efforts. This comes after Germany’s financial regulator BaFin took enforcement action, ordering a halt to USDe sales due to compliance failures. Ethena has now migrated operations to its British Virgin Islands-based entity.

BaFin cited concerns over Ethena’s reserve practices and flagged its yield-bearing stablecoin (sUSDe) as a potential unregistered security. The regulator ordered a freeze on reserves and redemptions via the German entity, while secondary market trading remains unaffected. Ethena emphasized that most USDe was issued outside of Germany and that its core operations continue under BVI jurisdiction.

AWS Outage Disrupts Binance, KuCoin, MEXC Services

A major Amazon Web Services (AWS) outage caused widespread service issues across multiple crypto exchanges including Binance, KuCoin, and MEXC. The network interruption affected at least 12 AWS services, halting some trades, asset transfers, and access to wallets. Binance and others confirmed partial outages but assured users that all funds remained secure.

The downtime has reignited concerns about centralized infrastructure dependencies in crypto, especially among exchanges reliant on AWS for high-speed trading. Several voices in the community called for exploring decentralized cloud alternatives to reduce single points of failure. By early afternoon UTC, most affected platforms had restored services, though some reported lingering delays.
