Stroom

Stroom receives a C+ risk grade (40/100) from Hindenrank, where lower scores indicate lower risk. Elevated risk — innovative Bitcoin liquid staking concept, but the federated bridge and cross-chain complexity introduce substantial trust and security assumptions. Stroom is a liquid staking protocol that lets you stake Bitcoin on the Lightning Network and receive lnBTC/stBTC tokens on Ethereum. You earn yield from Lightning Network routing fees while using the wrapped tokens in Ethereum DeFi. With $13M TVL and $3.5M in seed funding, it is a novel but early-stage protocol bridging Bitcoin, Lightning, and Ethereum.

The key risks identified for Stroom are: (1) Your BTC is locked in a federated bridge controlled by a small set of operators — if their keys are compromised, locked Bitcoin could be stolen (2) Lightning Network routing fees are variable and may not always provide competitive yield compared to other BTC yield products (3) The protocol spans three networks (Bitcoin, Lightning, Ethereum), creating a large attack surface with multiple potential failure points

Stroom scores 40/100 across eight risk dimensions: Mechanism Novelty: 9/15, Interaction Severity: 6/20, Oracle Surface: 5/10, Documentation Gaps: 4/10, Track Record: 7/15, Scale Exposure: 0/10, Regulatory Risk: 3/10, Vitality Risk: 6/10. The highest risk area is Mechanism Novelty at 9/15.
