StakeStone

StakeStone is an omnichain liquidity protocol that turns deposited ETH, BTC, or stablecoins into transferable, yield-bearing receipt tokens; its flagship ETH product is STONE, a liquid staking token.

The receipt token represents your claim on the underlying pool while the protocol deploys the deposit into yield strategies.

STONE is deliberately non-rebasing: your wallet balance stays fixed, while the amount of ETH each STONE can be redeemed for increases as the underlying strategies earn.

STONE is an ERC-20, using the interfaces defined by the ERC-20 token standard, and a LayerZero Omnichain Fungible Token; the OFT standard describes how fungible tokens can exist across chains with a unified supply. The same asset moves across supported networks. The canonical Ethereum contract address is 0x7122985656e38BDC0302Db86685bb972b145bD3C.

StakeStone works by issuing STONE at a contract-defined exchange rate, then allocating deposited ETH across whitelisted Strategy Pools through OPAP governance.

The transaction sequence is connect a wallet, select a product, review the exchange rate, approve, and deposit. For STONE, ETH enters the StakeStone Vault and the Minter contract issues STONE; OPAP can add or reweight staking and restaking routes.

Those staking routes participate in proof-of-stake consensus; the allocation policy can change through governance instead of staying fixed to one operator set.

Yield appears as redemption value per STONE, calculated as underlying pool value divided by token supply. That protocol exchange rate is separate from a DEX price. Governance is handled by STO, the ERC-20 utility token; locking STO produces vote-escrowed veSTO.

StakeStone offers three routes with different custody profiles: STONE for ETH, STONEBTC for BTC, and STONEUSD for stablecoins.

• STONE (ETH) is the fully on-chain route: contracts, vault, strategy pools, and on-chain governance.
• STONEBTC provides yield on BTC and may involve custodians and centralized venues alongside contracts.
• STONEUSD provides stablecoin yield and may involve off-chain execution, exchanges, and KYC.

The protocol name is shared, but the custody model is not: STONE is the fully on-chain route described here, while the other two can include off-chain parties.

STONE rewards accrue through its redemption value rather than through separate payouts.

The value comes from yield generated by underlying staking and restaking strategy pools; the displayed rate is variable because strategy performance, validator performance, restaking conditions, and OPAP allocation decisions can change.

The practical measure is the current exchange rate and any rate shown in the official app at deposit; a quoted APY is a snapshot for a strategy-governed pool, not a fixed rate. For context, pooled staking overview explains how pooled staking routes ETH through a shared service rather than a solo validator.

StakeStone's material risks are smart-contract, strategy and restaking, exit-liquidity, market, counterparty, and key risks.

• Smart-contract risk: published audits cover protocol products and contracts, but a vault or strategy-pool exploit remains a loss scenario.
• Strategy and restaking risk: STONE can allocate across approved staking and restaking routes, and restaking adds slashing conditions on top of base staking.
• Exit-liquidity risk: instant redemption depends on buffer liquidity; a short buffer means waiting for unstaking and the next settlement cycle.
• Market risk: a DEX sale can be below the protocol exchange rate, and the underlying asset price can fall further than accrued yield covers.
• Custody and counterparty risk: STONEBTC and STONEUSD can add custodians, exchanges, centralized venues, and KYC-gated processes.
• Key risk: self-custody makes key management your responsibility; a support desk cannot recover lost keys.

To start, select the product, verify the route and contract, then approve and confirm a deposit.

1. Select the product and wallet. Use STONE for on-chain ETH, STONEBTC for BTC, or STONEUSD for stablecoins, then connect a wallet you control.
2. Review the transaction. Navigate to the official app, confirm the canonical Ethereum STONE contract is 0x7122985656e38BDC0302Db86685bb972b145bD3C, and read the displayed exchange rate before approving.
3. Deposit and record the baseline. Approve the token transaction, deposit, confirm that STONE arrived, and note the exchange rate at entry for later accrual tracking.

You can exit STONE either through protocol redemption or by selling it on a secondary market.

Protocol redemption burns STONE and returns ETH at the contract exchange rate: immediately when the vault has buffer liquidity, or after unstaking completes and the next settlement cycle runs when it does not.

A secondary-market sale lets you swap STONE at the market price rather than the protocol exchange rate. The phrase liquid staking token describes the transferable receipt, not an unconditional instant redemption path.
