Overview

Stroom introduces strBTC (Stroom BTC) – an economically secured yield-bearing BTC.

strBTC is a wrapped Bitcoin asset designed by Stroom to provide both native BTC yield generation and economic security.

BTC Yield Generation

Stroom deploys BTC liquidity across the Bitcoin infrastructure projects, enabling strBTC holders to earn native, low-risk yield from:

• Lightning Network routing fees,

• BitVM2 operator staking,

• Liquidity provision for BitVM2 atomic swap bridges,

• Various Bitcoin L2 like CoreDAO.

As new sources of real BTC-native yield emerge, Stroom's DAO will evaluate and integrate them to further enhance the earning potential of strBTC holders.

Economic Security

strBTC is secured by a whitelisted, federated, multi-collateral bridge underpinned by restaking infrastructure (e.g., via Eigenlayer and Symbiotic). In the event of malicious activity or failure by bridge operators, their restaked ETH or USD tokens are slashed to cover any resulting debt, ensuring the integrity of the system and the protection of users' assets.

A New Standard for BTC Bridging and Collateral

This restaking-backed bridge model offers greater scalability and security than traditional bridges reliant on native token staking. At the same time, yield-bearing BTC—such as strBTC—serves as more capital-efficient collateral compared to conventional wrapped BTC.

strBTC is the only bridged Bitcoin asset economically secured through restaking and the only yield-bearing BTC that sources yield directly from native Bitcoin infrastructure.
