# Meteora Launchpad Total value locked Methodology

## 1. Overview

Total value locked (TVL) measures the total value of assets deposited in Meteora Launchpad. It is used as a leading indicator for liquidity and trading activity within the launchpad ecosystem. Meteora Launchpad pools are comprised of active Dynamic Bonding Curve (DBC) pools and Dynamic AMM (DAMM) pools that originated from a DBC graduation. Assets are held in vault accounts associated with these pools, and their aggregate value is used to represent the total capital committed to the launchpad.

## 2. Data sources

- **Blockchain events**: `Migration` instructions from `DBC` programs, and token balance changes for vault accounts associated with Meteora Launchpad pools, covering Solana
- **External data**: End-of-day price feeds for deposited assets

## 3. Step-by-step calculation

### Component A: Pool origin and product attribution

- **Purpose**: Identify and attribute pools to Meteora Launchpad
- **Logic**: Pools are attributed to Meteora Launchpad if they are identified as Dynamic Bonding Curve (DBC) pools or if they are Dynamic AMM (DAMM) V1 or V2 pools that originated from a DBC bonding-curve graduation. Graduation is determined by parsing `Migration` instructions from the `DBC` program. Pools that do not originate from a DBC graduation are attributed to other products, such as Meteora Liquidity Pools.
- **Key fields**: `pool_address`, `base_mint`, `instruction_type`

### Component B: Vault balance tracking

- **Purpose**: Track daily token balances for the identified pools
- **Logic**: Vault accounts associated with each pool are identified from trade records. Daily token balances for these vault accounts are extracted from token balance changes on Solana. If a single vault account is associated with multiple pools, the balance is distributed proportionally across those pools to prevent double-counting. Missing daily balances are filled forward from the last known balance.
- **Key fields**: `account_address`, `token_address`, `token_amount`, `pool_address`

### Component C: USD conversion and final aggregation

- **Purpose**: Convert token balances to USD and aggregate the final TVL
- **Logic**: Token balances are grouped by day, asset, and product. The balances are normalized by decimal precision and multiplied by end-of-day asset prices to calculate the USD value. The final TVL is aggregated daily, and any missing days are filled forward to ensure continuous time-series data.
- **Key fields**: `timestamp`, `token_address`, `tvl`, `price_usd`
