Stakers deposit funds into StakeStone and receive a return on investment in the form of staking rewards (supply-side fees). StakeStone then deploys the staked capital to Lido.

StakeStone is an omni-chain LST (Liquid Staking Token) protocol aiming to bring native staking yields and liquidity to Layer 2s. StakeStone was founded by a anonymous team and launched in 2023.

StakeStone team controls the protocol. They do not currently take a cut of the total staking rewards earned by the protocol (revenue).

# StakeStone Total value locked Methodology

## 1. Overview

StakeStone TVL (Total Value Locked) represents the total value of ETH assets currently staked in the StakeStone liquid staking protocol. The metric is calculated by tracking the cumulative net flow of ETH deposits and withdrawals through StakeStone's vault contracts, then converting the running balance to USD using end-of-day price feeds. This provides a real-time view of how much value is locked in the protocol for liquid staking services.

## 2. Data sources

The calculation relies on the following raw data sources:

- **Blockchain events**: Parsed Ethereum `Deposit` events from StakeStone v1's `StoneVault` contract that capture ETH deposits into the protocol
- **Transaction data**: Ethereum transaction traces from StakeStone v1's `AssetVault` withdraw function calls that record ETH withdrawals from the protocol  
- **External data**: End-of-day ETH price feeds for USD conversion and ETH token metadata for decimal corrections
- **Protocol contracts**: StakeStone v1 vault contracts on Ethereum mainchain, with special handling for internal protocol operations

## 3. Step-by-step calculation

### Component A: Deposit tracking
- **Purpose**: Captures all ETH deposits into StakeStone's liquid staking vault
- **Logic**: Extracts all `Deposit` events from the StakeStone v1 `StoneVault` contract on Ethereum. Each event contains the deposited amount, block timestamp, transaction hash, and log index. All deposits are classified as ETH deposits using the WETH token address `0xc02aaa39b223fe8d0a0e5c4f27ead9083c756cc2`
- **Key fields**: `amount` (deposit quantity), `block_timestamp` (when deposit occurred), `transaction_hash` and `log_index` (unique event identifier)

### Component B: Withdrawal tracking  
- **Purpose**: Captures all legitimate ETH withdrawals from StakeStone's vault, excluding internal protocol operations
- **Logic**: Extracts successful withdraw function calls from the StakeStone v1 `AssetVault` contract. Filters out internal withdrawals to the StrategyController contract address `0x396abf9ff46e21694f4ef01ca77c6d7893a017b2` and only includes transactions with successful status. This ensures only genuine user withdrawals are counted
- **Key fields**: `amount` (withdrawal quantity), `block_timestamp` (when withdrawal occurred), `to` address (withdrawal recipient), `status` (transaction success flag)

### Component C: Daily balance calculation
- **Purpose**: Computes daily net balance changes and running cumulative balances
- **Logic**: Combines deposits (positive amounts) and withdrawals (negative amounts) into a unified dataset. Truncates timestamps to daily boundaries and groups transactions by day, chain, product, account name, and token address. Sums amounts within each day to get daily net balance changes. Fills missing days with zero values to ensure continuous time series. Applies decimal correction for ETH's 18 decimal places
- **Key fields**: `amount` (daily net change), `timestamp` (daily boundary), product and chain identifiers

### Component D: Running balance accumulation
- **Purpose**: Calculates the cumulative running balance of staked assets over time
- **Logic**: Uses window functions to compute running sum of daily balance changes, partitioned by chain, business line, product, version, account name, and token address. Orders by timestamp to maintain chronological accumulation. This produces the total staked assets balance at each point in time
- **Key fields**: `amount` (cumulative staked balance), partitioning dimensions for proper accumulation scope

### Final aggregation
- **Combining components**: The running balance from Component D represents the total staked assets in ETH terms
- **Currency conversion**: Converts ETH amounts to USD using end-of-day price feeds, applying the conversion after decimal correction
- **Time aggregation**: Maintains daily granularity with gap-filling to ensure no missing dates in the time series
- **Final calculation**: TVL equals the current cumulative staked assets balance in USD. The metric represents the total value of ETH currently locked in StakeStone's liquid staking protocol after accounting for all deposits and withdrawals
