Moderate risk — advanced cryptography protects against fraud, but repeated outages and a single-operator sequencer undermine the security promises

Top Risks

1

Repeated sequencer outages (Sep 2025, Jan 2026) expose fragile liveness with 18 minutes of reverted blocks

2

Cairo VM is a non-EVM execution environment requiring entirely new tooling and audit expertise

3

Centralized sequencer with no permissionless fallback creates single point of failure for transaction inclusion

Risk Breakdown

Frequently Asked Questions

Is Starknet safe to use?
Starknet receives a C+ risk grade (39/100) from Hindenrank, where lower scores indicate lower risk. Moderate risk — advanced cryptography protects against fraud, but repeated outages and a single-operator sequencer undermine the security promises An Ethereum Layer 2 that uses zero-knowledge STARK proofs for security and a custom programming language called Cairo. It holds $716M in deposits with $287M in funding. Its C grade reflects repeated sequencer outages, a non-standard codebase with limited security auditors, and a single company controlling transaction processing.
What are the main risks of using Starknet?
The key risks identified for Starknet are: (1) The sequencer has gone down multiple times (September 2025, January 2026). During outages, you cannot trade, manage loans, or withdraw to Ethereum. If you have a leveraged position, you cannot save it (2) Cairo is a custom language that very few security auditors know how to review. Bugs that would be caught quickly in Ethereum's Solidity code could go undetected for months on Starknet (3) One company (StarkWare) runs the sequencer. There is no backup. If they go offline, censor transactions, or make an error, all $716M in user funds are affected
What is Starknet's risk score breakdown?
Starknet scores 39/100 across eight risk dimensions: Mechanism Novelty: 8/15, Interaction Severity: 8/20, Oracle Surface: 0/10, Documentation Gaps: 3/10, Track Record: 7/15, Scale Exposure: 5/10, Regulatory Risk: 2/10, Vitality Risk: 6/10. The highest risk area is Vitality Risk at 6/10.
How does Starknet compare to other L2 protocols?
Among 37 rated L2 protocols on Hindenrank, Starknet ranks #25 by safety (lowest risk score = safest). Its 39/100 risk score and C+ grade place it in the middle tier of L2 protocols.
Has Starknet ever been hacked or exploited?
Starknet scores 7/15 on the Track Record risk dimension, indicating some history of security incidents or exploits. Higher scores reflect more severe or frequent incidents. Review the full risk report for details.
