§ 01 Executive Snapshot

What: Aztec urges users on its Alpha V4 network to withdraw funds by June 25 due to security vulnerabilities that will be revealed with the upcoming V5 upgrade.
Who: Aztec Foundation and its users on the Alpha V4 network.
Why it matters: The public disclosure of V4's vulnerabilities poses a significant risk to user funds, emphasizing the importance of security in decentralized finance (DeFi).

Aztec plans to transition to V5 on June 25, which will expose the current security vulnerabilities in V4.
The governance proposal for V5 requires public disclosure of V4 flaws, increasing the risk for any remaining funds.
A critical vulnerability in Alpha V4 was disclosed in March 2026, affecting the proving system and potentially leading to theft of user funds.

The migration notice is part of Aztec's standard upgrade cycle, reflecting the protocol's commitment to transparency and security.
Aztec has previously warned users about the experimental nature of deposits on its platforms, indicating that users should only invest amounts they can afford to lose.

Immediate withdrawal of funds is necessary to mitigate the risk posed by known vulnerabilities that will be disclosed post-upgrade.
Long-term, the incident underscores the importance of security measures and user education in DeFi platforms, potentially affecting user trust and participation.

Potential for significant user losses if funds are not withdrawn before the vulnerabilities are publicly disclosed.
The risk of operational disruptions as users rush to withdraw their assets before the June 25 deadline, possibly leading to congestion on the L1-to-L2 bridge.

The V5 governance proposal is set to go on-chain on June 25, marking a critical moment for current V4 users.
Future developments will include the release of V5 and the expected impact on user trust and asset security in the Aztec ecosystem.
