Is Stroom Safe?
Risk Grade: C+ (40/100)
Stroom is rated as elevated risk — multiple novel mechanisms and notable interaction risks.
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.

Key Risks for Stroom Users
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
Lightning Network routing fees are variable and may not always provide competitive yield compared to other BTC yield products
The protocol spans three networks (Bitcoin, Lightning, Ethereum), creating a large attack surface with multiple potential failure points
Top Risk Factors
- •Novel cross-chain bridge between Bitcoin Lightning Network and Ethereum introduces complex trust assumptions — federated bridge infrastructure is a known attack vector
- •Lightning Network routing fee yield is inherently variable and may not justify the complexity and risk of the cross-chain staking architecture
- •The protocol relies on a federated bridge rather than trustless verification, creating custodial risk for BTC locked in the system
Risk Score Breakdown
Stroom's highest risk area is Mechanism Novelty (9/15). Here's how each dimension contributes to the overall 40/100 score:
