Native ETH stakers or LST (liquid staking token) holders can deposit assets to and withdraw assets from Symbiotic.

Symbiotic is a shared security protocol that serves as a thin coordination layer, empowering network builders to control and adapt their own (re)staking implementation in a permissionless manner

Symbiotic team and investors own and govern the protocol. Symbiotic's investors include Paradigm and cyber•Fund.

# Symbiotic Total value locked Methodology

## 1. Overview

Symbiotic TVL (Total Value Locked) measures the total USD value of tokens held in Symbiotic protocol's collateral and vault accounts. This metric quantifies the capital deposited into the Symbiotic liquid staking protocol by aggregating token balances across all registered accounts and converting them to USD values. The calculation treats net deposits as equivalent to TVL, representing the total value of assets under management in the protocol.

## 2. Data sources

- **Ethereum factory events**: Parsed `AddEntity` events from the Symbiotic DefaultCollateralFactory contract that register new collateral accounts, plus similar events from VaultFactory contracts that register vault accounts
- **Ethereum token transfers**: Token transfer events and balance change data for all identified Symbiotic accounts to track inflows and outflows
- **End-of-day price feeds**: Daily token price data in USD for converting token balances to dollar values
- **Token metadata**: Token symbol and decimal precision information for proper balance calculations

## 3. Step-by-step calculation

### Component A: Account identification
- **Purpose**: Identify all Symbiotic protocol accounts that should be monitored for TVL calculation
- **Logic**: Extract account addresses from Ethereum `AddEntity` events emitted by the DefaultCollateralFactory contract. These events register new collateral accounts in the Symbiotic protocol. Similarly extract vault account addresses from VaultFactory events. Combine both collateral and vault accounts into a comprehensive list of addresses to monitor
- **Key fields**: The `entity` field from factory events provides the account addresses that hold protocol assets

### Component B: Token balance tracking
- **Purpose**: Calculate token balances for all monitored Symbiotic accounts over time
- **Logic**: Process Ethereum token transfer events to identify balance changes for each monitored account address. Use balance change calculation logic to determine net token flows into and out of each account. Apply cumulative sum windowing functions partitioned by account address and token address to convert balance changes into absolute token balances over time. Forward-fill balance values during periods with no activity to maintain consistent time series data
- **Key fields**: Account `address`, `token_address`, `balance` changes, and `timestamp` for temporal tracking

### Component C: USD conversion and filtering  
- **Purpose**: Convert token balances to USD values and filter for positive balances
- **Logic**: Join token balance data with end-of-day price feeds using timestamp, chain, and token address. Multiply token balances by corresponding USD prices to get dollar values. Filter to include only positive balances, excluding accounts with zero or negative positions
- **Key fields**: Token `balance` amounts, `price_usd` from price feeds, calculated `amount` in USD

### Final aggregation
- **Combining components**: Sum all USD-denominated token balances across all monitored Symbiotic accounts and tokens to get total protocol value
- **Currency conversion**: Token balances are converted to USD using end-of-day price feeds with daily granularity
- **Time aggregation**: Data is aggregated at daily boundaries with forward-filling to handle missing periods
- **Final calculation**: The total net deposits value represents TVL - the sum of all positive USD token balances held in Symbiotic collateral and vault accounts. Missing time periods are filled with zeros using the finalize metric macro, and chain availability filters ensure data quality
