How Does Bedrock uniETH Work?

Restaking|Risk C+|6 mechanisms|5 interactions

Bedrock uniETH is a multi-asset liquid restaking protocol that issues uniETH, a non-rebasing token representing staked and EigenLayer-restaked ETH. Built in partnership with RockX infrastructure, it operates across 5+ chains including Arbitrum, Linea, and Scroll. In September 2024, the protocol suffered a $2M exploit on its uniBTC contract caused by a former employee inserting backdoor code, though uniETH was not directly affected. Its C+ risk grade reflects the prior exploit track record, EigenLayer restaking dependency, and multi-chain attack surface, partially offset by post-exploit security improvements including Chainlink proof-of-reserves integration.

Core Mechanisms

3.4.2

uniETH — non-rebasing liquid restaking token that grows in value as ETH staking and EigenLayer restaking rewards accrue

Standard reward-bearing LRT pattern. uniETH value increases over time relative to ETH. Non-rebasing design for DeFi composability.

8.3.1

EigenLayer restaking — underlying ETH is staked and then restaked on EigenLayer to secure additional AVS services for additional yield

Standard EigenLayer restaking pattern used by multiple LRT protocols. Adds yield from AVS services but also slashing risk.

8.2.3

Novel

Multi-chain uniETH deployment across Arbitrum, Linea, Scroll, Manta, and IoTeX

Broader multi-chain deployment than most LRT protocols. Native cross-chain restaking creates complex supply management across 5+ chains.

7.3.1

Points system — Bedrock Diamonds and EigenLayer restaked points distributed to uniETH holders for future token conversion

Standard points-to-token system for early depositor incentivization.

6.4.1

Chainlink proof-of-reserves integration for uniETH backing verification (added post-exploit)

Standard Chainlink oracle integration. Implemented as a security improvement after the September 2024 uniBTC exploit.

3.3.2

RockX infrastructure partnership for validator operations and non-custodial staking

Pooled delegation managed through RockX, a blockchain infrastructure company. Non-custodial design but dependent on single infrastructure provider.

How the Pieces Interact

EigenLayer restaking (8.3.1)uniETH LRT value (3.4.2)High

uniETH's value depends on both base ETH staking yield and EigenLayer restaking yield. A slashing event on an AVS where uniETH's underlying ETH is restaked would directly impair the uniETH exchange rate, affecting all holders across all chains.

Multi-chain deployment (8.2.3)uniETH supply managementHigh

uniETH exists on 5+ chains. A bridge exploit or supply invariant violation on any chain could create unbacked uniETH tokens, diluting all holders. Cross-chain accounting complexity increases vulnerability surface.

September 2024 insider exploitDevelopment process securityMedium

The $2M uniBTC exploit was caused by a former employee inserting malicious backdoor code that remained undetected for weeks. This demonstrates that the development process has had insider threat vulnerabilities that could potentially affect other contracts including uniETH.

RockX infrastructure dependency (3.3.2)Validator operationsMedium

Single infrastructure provider (RockX) for validator operations creates centralization risk. If RockX experiences downtime, key compromise, or business failure, all uniETH staking operations are affected.

Points system (7.3.1)TVL sustainabilityMedium

Points-based incentives attract mercenary capital. When points campaigns end or convert to tokens, depositors may withdraw, causing rapid TVL decline and uniETH liquidity reduction.

What Could Go Wrong

  1. Bedrock suffered a $2M exploit in September 2024 on the uniBTC contract, caused by a former employee who inserted malicious backdoor code. While uniETH was not directly affected, it demonstrates insider threat risk in the protocol's development process.
  2. uniETH restakes underlying ETH on EigenLayer, creating compounding dependency risk — a slashing event or exploit on an EigenLayer AVS would directly impair uniETH's value.
  3. Multi-chain deployment across Arbitrum, Linea, Scroll, Manta, and IoTeX creates a large cross-chain attack surface where a vulnerability on any supported chain could affect uniETH holders.
  4. Partnership with RockX as infrastructure provider creates a centralization dependency on a single infrastructure company for staking operations and key management.

EigenLayer AVS Slashing Cascade Impairs uniETH Backing

Moderate

Trigger: An EigenLayer AVS where Bedrock has restaked >20% of uniETH's underlying ETH experiences a major slashing event due to operator misbehavior or software bug

  1. 1.EigenLayer AVS triggers slashing conditions, penalizing restaked ETH from Bedrock's validator operations uniETH's underlying ETH backing decreases by the slashed amount, impacting the uniETH/ETH exchange rate
  2. 2.uniETH exchange rate drops across all 5+ supported chains as the reduced backing is reflected in pricing DeFi positions using uniETH as collateral on Arbitrum, Linea, Scroll, and other chains face potential liquidation
  3. 3.uniETH holders across multiple chains rush to redeem or sell on secondary markets Cross-chain redemption demand creates congestion; secondary market liquidity on smaller chains is insufficient
  4. 4.uniETH depeg on secondary markets as sell pressure exceeds available liquidity Holders on chains with thinner liquidity face larger discounts; cross-chain arbitrage is slow to equalize prices
