Hedera

Hedera receives a C+ risk grade (36/100) from Hindenrank, where lower scores indicate lower risk. Hedera's Governing Council structure enables rapid response to incidents — both the 2023 and 2026 HTS precompile exploits were patched within hours. However, the same attack vector exploited twice in three years on different third-party protocols indicates a systemic interface risk that periodic patches have not resolved. Enterprise adoption (IBM, Boeing, LG) provides a credible use-case moat, but the DeFi ecosystem's reliance on a precompile architecture with two confirmed exploits limits upside until the underlying interface design is formally audited and hardened. Hedera is a public distributed ledger using the patented hashgraph consensus algorithm, governed by a council of 28 major enterprises including Google, IBM, and Boeing. With approximately $60M in DeFi TVL and a $5B fully diluted valuation, it has been operational since September 2019 with strong theoretical security (aBFT consensus) but limited DeFi adoption. Its B- grade reflects a clean track record with only one smart contract exploit in 2023 (quickly contained), balanced against significant centralization in its Council-operated consensus model and a large valuation-to-TVL gap that creates scale exposure risk.

The key risks identified for Hedera are: (1) All consensus nodes are operated exclusively by 28 Governing Council members (enterprises like Google, IBM, Boeing), making Hedera effectively a permissioned network despite being called public (2) The hashgraph consensus algorithm is patented by Swirlds Inc., creating intellectual property dependency that prevents the open-source fork-ability typical of other L1 blockchains (3) DeFi ecosystem remains small at approximately $60M TVL after 5+ years of operation, with over two-thirds concentrated in a single protocol (SaucerSwap) (4) HBAR stakers earn rewards but have no governance influence — only the 28 Council members control network parameters and decisions

Hedera scores 36/100 across eight risk dimensions: Mechanism Novelty: 3/15, Interaction Severity: 4/20, Oracle Surface: 0/10, Documentation Gaps: 2/10, Track Record: 8/15, Scale Exposure: 7/10, Regulatory Risk: 6/10, Vitality Risk: 6/10. The highest risk area is Scale Exposure at 7/10.

Among 56 rated L1 protocols on Hindenrank, Hedera ranks #33 by safety (lowest risk score = safest). Its 36/100 risk score and C+ grade place it in the middle tier of L1 protocols.

Hedera scores 8/15 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.
