Is Balancer Safe?
Risk Grade: C (49/100)
Balancer is rated as elevated risk — multiple novel mechanisms and notable interaction risks.
Elevated risk — $128M exploit in November 2025 was Balancer's third major incident, and vulnerable V2 pools remain active across multiple chains during migration
A decentralized exchange known for customizable pool weights and composable stable pools. It holds $106M in deposits, down 58% from $775M after a $128M exploit in November 2025 caused by a rounding error in its pool math. Its C- grade reflects the severe recent exploit and ongoing migration risk from vulnerable V2 pools.

Key Risks for Balancer Users
A $128M hack in November 2025 exploited a math error in the pool calculations. This was Balancer's third major security incident.
Old V2 pool contracts with known vulnerabilities are still active across multiple blockchains. Your funds may be in these vulnerable pools until migration to V3 is complete.
58% of deposits left after the exploit. If another vulnerability is found, the remaining depositors face concentrated risk.
Top Risk Factors
- •$128M exploit in November 2025 via rounding error in V2 composable stable pool invariant calculation. The largest DEX exploit in DeFi history at that scale.
- •58% TVL collapse post-exploit ($775M to $258M) signals deep erosion of protocol trust and institutional confidence.
- •Multi-chain V2 pools remain vulnerable until fully migrated to V3. Legacy pool exposure persists across multiple chains.
How Balancer Compares to Peers
Balancer ranks #103 of 111 DEX protocols (bottom quartile — among the riskiest). At a risk score of 49/100, it's 15 points riskier than the sector average of 34/100.
Adjacent peers: Magma Finance (C, 46/100) is ranked just safer, and Orderly Network (C, 49/100) is ranked just riskier.

Common Questions about Balancer
Plain-English answers based on Balancer's scores across Hindenrank's 8 risk dimensions. The highest-scoring (riskiest) dimension is Track Record (15/15).
Has Balancer ever been hacked or exploited?
Balancer has a documented incident history that materially raised its risk grade — the track record dimension scored 15/15, near the high end of the scale. Past exploits, governance failures, or contract issues are baked into this rating. Anyone considering deposits should review the incident details before allocating capital.
How much money is at stake in Balancer?
Balancer currently holds roughly $81M in user deposits. Smaller TVL means individual depositors carry a larger share of any loss event, and it can be harder to exit a position quickly during stress.
What's the worst-case scenario for Balancer?
Hindenrank has identified specific collapse scenarios for Balancer. The most prominent: "Legacy V2 Pool Re-Exploitation". The trigger condition is A new vulnerability is discovered in Balancer V2 pool contracts while $50M+ remains in unmigrated V2 pools across multiple chains. 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 Balancer regulated or insured?
Balancer 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 Balancer?
Hindenrank's retail-focused risk audit flagged: A $128M hack in November 2025 exploited a math error in the pool calculations. This was Balancer's third major security incident. Old V2 pool contracts with known vulnerabilities are still active across multiple blockchains. Your funds may be in these vulnerable pools until migration to V3 is complete. 58% of deposits left after the exploit. If another vulnerability is found, the remaining depositors face concentrated risk. On the technical side, 2 critical-severity interaction risks have been identified.
Should beginners deposit into Balancer?
Balancer'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 Balancer compare to safer DEX alternatives?
Balancer is one protocol in Hindenrank's DEX coverage. The safest DEX protocols on the leaderboard tend to share three traits: a long incident-free track record, conservative mechanism design, and high-quality public documentation. Compare Balancer against the full DEX ranking before committing capital.
