# Sanctum Infinity Total value locked Methodology

## 1. Overview

Total value locked (TVL) measures the total value of assets deposited into the Sanctum Infinity liquidity pool. Sanctum Infinity acts as a multi-LST (Liquid Staking Token) liquidity pool that allows users to swap between various staking assets and earn yields. This metric serves as a key indicator of the liquidity available within the Sanctum Infinity ecosystem and the total capital committed by liquidity providers.

## 2. Data sources

- **Blockchain events**: Solana account balances and SPL token `Mint` and `Burn` instructions, covering Solana
- **External data**: End-of-day price feeds for native assets and underlying collateral

## 3. Step-by-step calculation

### Component A: Infinity pool asset tracking

- **Purpose**: Identify and track all assets held within the Sanctum Infinity liquidity pool.
- **Logic**: The Sanctum Infinity pool is identified through the owner account `AYhux5gJzCoeoc1PoJ1VxwPDe22RwcvpHviLDD1oCGvW`. All token accounts associated with this owner are monitored to capture the balances of various Liquid Staking Tokens (LSTs) and other supported assets held within the pool.

### Component B: Balance extraction and temporal alignment

- **Purpose**: Maintain a continuous daily record of asset balances.
- **Logic**: Daily balances for each asset are extracted from Solana account balance changes. To ensure data continuity, balances are filled forward for days where no on-chain balance changes are recorded, ensuring that the latest known balance is used for daily valuation.

### Component C: Asset valuation and LST pricing

- **Purpose**: Assign a USD value to the tracked assets.
- **Logic**: Assets are converted to USD using end-of-day price feeds. For specialized Liquid Staking Tokens (LSTs) where direct market prices are unavailable, a fair value is derived by calculating the ratio between the total underlying staked assets and the total outstanding supply. The outstanding supply is determined by aggregating historical SPL token `Mint` and `Burn` instructions for each specific LST.

### Component D: Final USD aggregation

- **Purpose**: Consolidate all asset values into a single daily TVL metric.
- **Logic**: Individual asset balances are normalized by their respective decimal precision and multiplied by the determined USD price. The resulting values are summed across all assets held by the Sanctum Infinity pool owner account to arrive at the daily Total value locked. Data is aggregated using UTC day boundaries.
