Sei

Sei receives a C+ risk grade (37/100) from Hindenrank, where lower scores indicate lower risk. Elevated risk — novel consensus modifications and parallelized EVM show technical ambition, but severe TVL decline and concentrated ecosystem raise material concerns about long-term viability. Sei is a Layer 1 blockchain designed for high-speed trading and DeFi applications, featuring a parallelized EVM with 400ms block finality. Originally a Cosmos SDK chain, it evolved into the first parallelized EVM blockchain with its V2 upgrade in 2024. However, its DeFi TVL has declined sharply from over $600M in mid-2025 to approximately $49M, raising significant concerns about ecosystem health. Its C+ grade reflects the combination of novel consensus modifications, limited production history since 2023, and substantial TVL decline, partially offset by no major security incidents and active development on the upcoming Giga upgrade.

The key risks identified for Sei are: (1) DeFi TVL has declined more than 90% from its mid-2025 peak of over $600M to approximately $49M, indicating significant capital flight from the ecosystem (2) Over 60% of remaining DeFi TVL is concentrated in a single protocol (Yei Finance), creating outsized dependency risk on one project (3) Monthly token unlocks of approximately 112-132 million SEI continue through 2026-2027, creating persistent sell pressure against declining demand (4) The parallelized EVM and Twin Turbo Consensus have less than 3 years of production history, limiting confidence in long-term reliability

Sei scores 37/100 across eight risk dimensions: Mechanism Novelty: 3/15, Interaction Severity: 8/20, Oracle Surface: 0/10, Documentation Gaps: 3/10, Track Record: 6/15, Scale Exposure: 7/10, Regulatory Risk: 3/10, Vitality Risk: 7/10. The highest risk area is Scale Exposure at 7/10.

Among 56 rated L1 protocols on Hindenrank, Sei ranks #36 by safety (lowest risk score = safest). Its 37/100 risk score and C+ grade place it in the middle tier of L1 protocols.
