Is Aztec Connect Safe?

|DeFi
C+

Risk Grade: C+ (42/100)

Aztec Connect is rated as elevated risk — multiple novel mechanisms and notable interaction risks.

Do NOT deposit new funds into Aztec Connect. The protocol is deprecated and the sequencer is offline. If you have existing funds, prioritize withdrawal immediately using documented emergency procedures. The Aztec team is building a new network, but Aztec Connect itself is end-of-life.

Aztec Connect was a privacy-preserving bridge that allowed users to interact with DeFi protocols on Ethereum while keeping their transactions private using zero-knowledge proofs. Users could access protocols like Aave and Lido while saving 80-90% on gas fees with privacy included for free. However, Aztec Connect was officially sunset in March 2023, with the sequencer (the system that processes transactions) shut down in March 2024. Any remaining funds are in deprecated smart contracts. The Aztec team has moved on to building a general-purpose privacy L2 network, with the AZTEC token launching in February 2026.

Key Risks for Aztec Connect Users

1.

This protocol is SHUT DOWN - the transaction processing system no longer operates, meaning you cannot use it normally

2.

Any funds still in Aztec Connect may be difficult to withdraw and require technical knowledge of emergency withdrawal procedures

3.

As a privacy tool, it faces similar regulatory risks to Tornado Cash, which was sanctioned by the US government in 2022

Top Risk Factors

  • Aztec Connect was officially sunset in March 2023, with the sequencer shut down in March 2024. Any remaining TVL is in a protocol that is no longer actively maintained or secured, creating an extreme operational risk.
  • The privacy features that made Aztec Connect attractive also attracted regulatory scrutiny. The shutdown was partially motivated by the need to focus on the next-generation privacy-preserving L2, but remaining funds are in deprecated infrastructure.
  • ZK-proof verification bugs in the rollup circuit could theoretically allow invalid state transitions. While the protocol was audited, the sunset means no ongoing security monitoring or patching.
