Is ZKsync Era Safe?
Risk Grade: C (43/100)
ZKsync Era is rated as elevated risk — multiple novel mechanisms and notable interaction risks.
Moderate risk — massive funding and strong technology, but proof system pauses and upgrade-enabled exploits reveal operational fragility
A layer-2 blockchain using zero-knowledge proofs to batch Ethereum transactions for lower fees and faster speeds. It manages $100M in deposits with $458M in funding -- one of the best-funded L2 projects. Its C grade reflects a proof system that has already been paused for vulnerabilities, a $5M airdrop exploit, and a $3.5M rug pull enabled by a protocol upgrade.

Key Risks for ZKsync Era Users
The proof system was manually paused due to a vulnerability -- during the pause, no withdrawals to Ethereum could be finalized
A protocol upgrade accidentally unlocked frozen funds, allowing a scam project to steal $3.5M from its own users
ZKsync Lite is shutting down in 2026 with $50M still on it -- if you miss the migration deadline, your funds could be permanently lost
Top Risk Factors
- •Proof system was manually paused due to vulnerability, causing partial liveness failure
- •Ecosystem suffered $5M airdrop exploit and $3.5M Gemholic rug pull enabled by protocol upgrade
- •ZKsync Lite deprecation in 2026 leaves ~$50M in bridged assets requiring migration
How ZKsync Era Compares to Peers

Common Questions about ZKsync Era
Plain-English answers based on ZKsync Era's scores across Hindenrank's 8 risk dimensions. The highest-scoring (riskiest) dimension is Vitality Risk (6/10).
Has ZKsync Era ever been hacked or exploited?
ZKsync Era has had some operational issues or moderate incidents in its history. The track record dimension scored 8/15 — not catastrophic, but enough to flag. Look at the specific events and whether they were addressed by the team before drawing conclusions.
How much money is at stake in ZKsync Era?
ZKsync Era currently holds more than $100M in user deposits. A protocol of this size typically has deeper liquidity, more eyes on the code, and more attention from auditors — but it also means a single failure has a much larger blast radius.
What's the worst-case scenario for ZKsync Era?
Hindenrank has identified specific collapse scenarios for ZKsync Era. The most prominent: "Proof System Liveness Failure". The trigger condition is SNARK proof system vulnerability requires emergency pause exceeding 24 hours while >$50M in pending withdrawals are queued through the canonical bridge. Reading through the full scenario list on the protocol page is the single best way to understand the actual failure modes — generic "smart contract risk" is rarely the thing that takes a protocol down.
Is ZKsync Era regulated or insured?
ZKsync Era has low regulatory exposure on Hindenrank's framework (2/10). The protocol is structured in a way that minimizes counterparty and jurisdiction concentration, though regulatory risk in crypto can change rapidly. No DeFi protocol carries FDIC-style insurance — even with low regulatory risk, depositors are not protected in the way bank customers are.
What are the biggest red flags for ZKsync Era?
Hindenrank's retail-focused risk audit flagged: The proof system was manually paused due to a vulnerability -- during the pause, no withdrawals to Ethereum could be finalized A protocol upgrade accidentally unlocked frozen funds, allowing a scam project to steal $3.5M from its own users ZKsync Lite is shutting down in 2026 with $50M still on it -- if you miss the migration deadline, your funds could be permanently lost
Should beginners deposit into ZKsync Era?
ZKsync Era's C grade puts it in the elevated-risk band. This is not a beginner-friendly protocol. Anyone depositing here should treat the position as speculative and avoid concentrating significant savings in it.
How does ZKsync Era compare to safer L2 alternatives?
ZKsync Era is one protocol in Hindenrank's L2 coverage. The safest L2 protocols on the leaderboard tend to share three traits: a long incident-free track record, conservative mechanism design, and high-quality public documentation. Compare ZKsync Era against the full L2 ranking before committing capital.
