How Does StakeStone Work?

Liquid Staking|Risk C+|8 mechanisms|5 interactions

A liquid staking protocol that lets you stake ETH and use the STONE token across multiple blockchains via LayerZero messaging. It holds $300M with $33M in funding. Its C+ grade reflects a custom cross-chain bridge design that deviates from standard patterns, creating unique failure modes for $300M in assets.

Core Mechanisms

3.4.2

STONE: reward-bearing omnichain LST that appreciates against ETH as yield accrues

STONE follows the reward-bearing LST pattern (similar to wstETH). Exchange rate increases over time as staking and strategy yields are added to the pool. Non-rebasing by design for DeFi composability.

8.2.3

Novel

Omnichain Fungible Token (OFT) via LayerZero with custom lock-without-burn bridging

Unlike standard OFT tokens that burn on source and mint on destination, StakeStone locks STONE on the source chain and mints on destination. This custom pattern preserves TVL accounting on the source chain but creates a non-standard bridge architecture with unique failure modes.

2.3.3

Novel

OPAP: decentralized governance for yield strategy portfolio allocation and optimization

OPAP (Optimizing Portfolio and Allocation Proposal) is a governance mechanism where STONE holders vote on which yield strategies the underlying ETH is deployed to. This is the first decentralized solution for optimizing LST yields via governance — novel because most LSTs have strategy decisions made by the team.

7.3.1

Points-based reward system with STO token conversion at TGE

StakeStone ran a points campaign pre-TGE where early depositors earned points convertible to STO tokens. Standard points-to-token conversion model with typical Sybil farming and sell pressure risks.

3.4.4

Novel

Unified LST across all chains via LayerZero messaging — single STONE token regardless of chain

STONE maintains a unified token representation across all supported chains. Unlike fragmented multi-chain LSTs, STONE's value is identical everywhere (in theory). This omnichain unification is a novel pattern for liquid staking.

8.1.3

LayerZero-based message passing for cross-chain STONE transfers and yield distribution

Cross-chain operations rely on LayerZero's messaging infrastructure for STONE transfers, yield updates, and governance coordination. Standard message-passing bridge dependency.

6.4.1

Chainlink and custom oracle feeds for STONE/ETH exchange rate across chains

STONE/ETH exchange rate communicated across chains via oracle feeds and LayerZero messages. Exchange rate oracle accuracy is critical for DeFi protocols accepting STONE as collateral.

5.1.1

STO token governance over OPAP strategy proposals and protocol parameters

STO token provides governance rights over yield strategy selection, fee parameters, and protocol upgrades. 1B total supply with 225M in initial circulation.

How the Pieces Interact

Custom lock-without-burn bridgeOmnichain STONE supplyCritical

The non-standard bridge mechanism creates risk of supply invariant violation: if the lock mechanism on the source chain fails or is exploited, unbacked STONE can proliferate across all destination chains simultaneously.

OPAP yield strategy governanceSTONE exchange rateHigh

Governance-approved strategies that suffer losses directly impair STONE's exchange rate for all holders across all chains. A single bad governance decision can create cross-chain losses with no chain-level isolation.

LayerZero messaging dependencyCross-chain STONE redemptionHigh

If LayerZero experiences downtime or censorship, STONE holders on non-Ethereum chains lose access to redemption. Cross-chain STONE becomes illiquid and trades at a discount during messaging outages.

Multi-strategy yield poolCross-chain collateral usageMedium

STONE used as collateral on L2 lending protocols assumes stable exchange rate appreciation. A yield strategy failure causing exchange rate decline triggers liquidations on chains that cannot verify the strategy pool health in real-time.

STO token governanceOPAP strategy selectionMedium

STO holders may vote for high-risk yield strategies that maximize short-term yield at the expense of STONE holder safety, creating principal-agent misalignment between governance token holders and LST depositors.

What Could Go Wrong

  1. Custom cross-chain bridge mechanism (lock-without-burn via LayerZero) creates non-standard attack surface for $300M+ in cross-chain STONE tokens
  2. OPAP governance-controlled yield strategy allocation means a single bad strategy can impair all STONE holders across all chains simultaneously
  3. Omnichain architecture fragments redemption access — users on L2s and alt-L1s cannot directly redeem STONE for ETH without bridging back to Ethereum

LayerZero Message Exploit and Cross-Chain STONE Supply Inflation

Moderate

Trigger: A vulnerability in LayerZero's OFT standard or StakeStone's custom bridging contracts allows unauthorized minting of STONE on a destination chain without corresponding ETH locked on the source chain

  1. 1.Attacker discovers vulnerability in StakeStone's custom LayerZero bridging contracts that bypasses the lock-without-burn mechanism Unauthorized STONE tokens minted on destination chain without corresponding ETH backing on Ethereum mainnet
  2. 2.Attacker sells unbacked STONE across multiple chains, crashing STONE/ETH exchange rate 20%+ Legitimate STONE holders on all chains suffer immediate mark-to-market losses as markets cannot distinguish real from unbacked STONE
  3. 3.DeFi protocols using STONE as collateral trigger mass liquidations across multiple chains simultaneously Cross-chain liquidation cascade amplifies the depeg as forced STONE selling occurs on every chain where STONE is used as collateral
  4. 4.StakeStone pauses cross-chain transfers to contain the exploit, fragmenting STONE liquidity STONE trades at different prices on different chains; users on non-Ethereum chains cannot redeem for underlying ETH, trapping capital
