# Meteora Liquidity Pools Total value locked Methodology

## 1. Overview

Total value locked (TVL) measures the total value of assets deposited in Meteora Liquidity Pools. This metric is used as a key indicator of the liquidity available for trading within the protocol's dynamic automated market maker (AMM) pools. By tracking the value of these deposits, the overall capacity of the protocol to facilitate low-slippage trades and generate trading fees can be assessed. The TVL of Meteora Liquidity Pools is specifically covered in this methodology, representing the dynamic liquidity market maker (DLMM) pools and non-graduated dynamic AMM V1 and V2 pools.

## 2. Data sources

- **Blockchain events**: Token balance changes, decentralized exchange trade records, and migration instructions from Meteora programs, covering Solana
- **External data**: End-of-day price feeds for deposited assets

## 3. Step-by-step calculation

### Component A: Meteora vault and pool identification

- **Purpose**: Identify the vault accounts and associated assets for Meteora pools
- **Logic**: Pool accounts, vault accounts (base and quote vaults), and asset mint accounts are extracted from decentralized exchange trade records on Solana. The executing programs are filtered to identify Meteora pools, specifically targeting the dynamic AMM programs, dynamic liquidity market maker (DLMM) programs, and bonding curve programs.
- **Key fields**: `pool_address`, `base_vault_address`, `quote_vault_address`, `base_mint_address`, `quote_mint_address`

### Component B: Meteora graduation and product attribution

- **Purpose**: Distinguish Meteora Liquidity Pools from Meteora Launchpad pools
- **Logic**: Migration instructions are parsed to identify pools that originated from bonding-curve graduations. Pools executing under the DLMM program and non-graduated dynamic AMM pools are attributed to Meteora Liquidity Pools, while graduated pools are attributed to Meteora Launchpad.
- **Key fields**: `pool_address`, `instruction_type`, `product_id`

### Component C: Meteora balance tracking and forward-filling

- **Purpose**: Track the daily asset balances held in the identified vault accounts
- **Logic**: Daily token balance changes for the identified vault accounts are aggregated to determine the closing balance of each asset. If no balance change is recorded on a given day, the last known balance is filled forward to ensure continuous daily coverage.
- **Key fields**: `timestamp`, `account_address`, `token_address`, `token_amount`

### Component D: Meteora proportional balance distribution

- **Purpose**: Prevent double-counting of vault balances across multiple pools
- **Logic**: In cases where a single vault account backs multiple pools, the vault balance is distributed proportionally by dividing the total balance by the number of associated pools.
- **Key fields**: `token_amount`, `account_address`, `product_id`

### Component E: USD conversion and final aggregation

- **Purpose**: Convert asset balances to USD and aggregate the total TVL
- **Logic**: The daily asset balances are multiplied by end-of-day asset prices to calculate the USD value. The USD values are then aggregated by day, chain, and product to produce the final daily TVL metric for Meteora Liquidity Pools.
- **Key fields**: `timestamp`, `chain_id`, `token_address`, `product_id`, `tvl`
