Bedrock uniBTC is a multi-asset liquid restaking protocol launched in 2023. It issues uniBTC, a liquid token representing restaked BTC, alongside uniETH and uniIOTX for Ethereum and IoTeX. With $0.3B in TVL across six chains, it integrates with Babylon, EigenLayer, and Symbiotic to offer staking yields while preserving liquidity for use in DeFi. This review analyzes its design, security posture, and position among restaking competitors.

What it is

Bedrock uniBTC is a liquid restaking token (LRT) protocol that tokenizes restaked assets, starting with BTC-oriented uniBTC. The project operates under Bedrock DAO and uses the BR governance token. It was built in collaboration with RockX, a blockchain infrastructure provider. The protocol aims to unlock restaking yield for Bitcoin holders while maintaining composability through liquid tokens. Its multi-asset approach extends to Ethereum via uniETH, tapping EigenLayer for restaking, and IoTeX via uniIOTX, covering a wider range than single-asset LRTs. As of 2026, Bedrock has onboarded users on Ethereum, Arbitrum, BNB Chain, Optimism, Base, and Mantle, reflecting a cross-chain ambition.

How it works

Users deposit BTC (via a wrapped or bridged representation) into Bedrock contracts and receive uniBTC, which accrues restaking rewards. The underlying BTC is then staked through Babylon's BTC restaking infrastructure or integrated restaking layers like EigenLayer and Symbiotic, depending on the asset. For example, ETH deposits mint uniETH and are routed to EigenLayer operators that secure Actively Validated Services (AVSs). The liquid tokens can be used in DeFi lending, trading, or as collateral, allowing holders to earn staking yield and additional DeFi yield simultaneously. Smart contract architecture relies on a set of deposit, withdrawal, and reward distribution modules, overseen by Bedrock DAO governance. Specific contract addresses are not publicly detailed in available sources. The BR token is used for protocol governance, with value accrual mechanisms tied to protocol fees. The system attempts to isolate slashing risk per asset type by using distinct restaking backends, but cross-asset contagion vectors remain a design consideration.

Key numbers

TVL: ~$0.3B ($319M, as of 2026-07-15, DeFiLlama)
Chains: 6 (Ethereum, Arbitrum, BNB, Optimism, Base, Mantle)
Launch year: 2023
Audits: 2 (SlowMist, Salus)
Assets: uniBTC, uniETH, uniIOTX
Governance token: BR
Incidents: None publicly reported

Security and audits

Bedrock uniBTC has completed two audits: one by SlowMist and one by Salus. No major vulnerabilities have been publicly disclosed, and the protocol has not suffered any recorded exploits as of 2026. However, the audit firms are less established in the restaking niche compared to firms like Trail of Bits, Sigma Prime, or Certora. The protocol’s governance and upgradability mechanics are not extensively documented; control likely rests with the Bedrock DAO and multisig signers, though details on timelocks or admin keys are scarce. The integration with multiple restaking layers (Babylon, EigenLayer, Symbiotic) introduces a dependency on the security practices of those base layers—slashing events there could cascade to Bedrock depositors. The absence of formal verification or additional top-tier audits raises the risk profile for a protocol handling cross-chain restaking.

Strengths

Multi-asset support: Bedrock is one of the few LRT protocols to offer liquid tokens for BTC, ETH, and IOTX, catering to diverse staker communities. EigenLayer, by comparison, only supports ETH restaking.
Cross-chain deployment: With six live chains, Bedrock provides wide accessibility, more than most LRT peers; Renzo Renzo spans seven chains, but focuses solely on ETH.
Integration with Babylon: uniBTC taps into Babylon’s BTC restaking, a novel primitive that extends Bitcoin’s economic security to PoS chains, a differentiator from Lido Lido or EigenLayer EigenLayer.

Weaknesses and risks

Low TVL relative to peers: At ~$0.3B, Bedrock’s TVL is only about 6% of EigenLayer’s ~$5.1B EigenLayer and under 2% of Lido’s ~$17.3B Lido, indicating limited adoption and liquidity depth.
Limited audit coverage: Only two audits, neither from a top-tier restaking specialist; compare to Renzo Renzo with audits from Halborn and Sigma Prime, and EigenLayer with Sigma Prime, Consensys Diligence, and Cantina.
Complex restaking dependencies: By integrating Babylon, EigenLayer, and Symbiotic simultaneously, the protocol multiplies its exposure to bugs, slashing events, or upgrades in any of those underlying systems, with little public documentation on risk mitigation.

How it compares

EigenLayer EigenLayer (~$5.1B TVL) dominates restaking with a focus on ETH and AVS security. It benefits from top-tier audits (Sigma Prime, Consensys Diligence, Cantina) and a first-mover advantage. Lido Lido (~$17.3B) is the largest liquid staking protocol, with deep liquidity and a long track record, but it does not offer BTC restaking. Renzo Renzo (~$0.1B) is a direct LRT competitor with wider chain coverage (seven chains) and stronger audit backing (Halborn, Sigma Prime), though it remains ETH-only. Bedrock’s differentiator is its BTC restaking via Babylon, which none of these peers provide. Its TVL now exceeds Renzo’s but remains an order of magnitude below EigenLayer and roughly two orders below Lido, and its audit depth and protocol maturity lag behind all three peers.

Verdict

Bedrock uniBTC offers a unique multi-asset restaking product, particularly its Bitcoin restaking integration, which sets it apart in a crowded LRT market. Yet its TVL is minuscule relative to category leaders, and its security assurances rely on only two audits from less prominent firms. The protocol has avoided incidents, but the complexity of bridging assets across restaking layers amplifies tail risk. For users seeking BTC yield via liquid restaking, Bedrock provides a functional vehicle, though the shallow liquidity and governance opacity warrant caution. Overall rating: 6.5/10.

Frequently asked questions

What is Bedrock uniBTC?

Bedrock uniBTC is a multi-asset liquid restaking protocol that issues uniBTC, a token representing restaked Bitcoin, along with uniETH and uniIOTX. It integrates with Babylon, EigenLayer, and Symbiotic to generate staking yield.

Is Bedrock uniBTC safe to use?

The protocol has been audited by SlowMist and Salus, with no reported exploits. However, the audit coverage is limited compared to top DeFi protocols, and the multi-layer restaking design carries additional smart contract and slashing risks.

How does Bedrock uniBTC make money?

The protocol likely generates revenue through staking fees, withdrawal fees, or a percentage of restaking yields. Details on fee structure are not publicly specified, but the BR token may capture value via protocol fees.

How many chains is Bedrock uniBTC on?

Bedrock uniBTC is deployed on six chains: Ethereum, Arbitrum, BNB Chain, Optimism, Base, and Mantle.

What is the BR token?

BR is the governance token of Bedrock DAO, used for protocol decision-making. It may also have fee-sharing or staking utility, though specific tokenomics are not detailed in available sources.
