# Asset TVL methodology

## 1. Overview

Asset TVL is calculated as the total value of a specific asset deposited into onchain applications, broken out by the protocol and product (venue) where it is deposited. This metric is utilized as a leading indicator of an asset's utility as productive collateral or liquidity across decentralized finance (DeFi). Currently integrated venues are comprised of lending markets such as Aave, Spark, Morpho, Venus, Kamino, and Flux, as well as DEX liquidity and vault products on Uniswap, Aerodrome, Orca, Raydium, xSwap, Mamo, Meteora, Instadapp, PancakeSwap, and Pendle. Coverage is expanded continuously as additional protocols and venues are integrated into the data pipeline.

## 2. Data sources

- **EVM chain events**: Protocol-specific TVL delta records, covering EVM-compatible chains (Ethereum, Arbitrum, Base, Polygon, Optimism, and others)
- **Solana instructions**: Protocol-specific TVL delta records, covering Solana
- **Asset metadata**: Token addresses, symbols, and decimal precision
- **External data**: End-of-day price feeds

## 3. Step-by-step calculation

### Component A: Extract daily TVL deltas

- **Purpose**: Retrieve the daily change in deposited asset quantities across integrated protocols and products.
- **Logic**: On EVM-compatible chains, daily net changes in asset balances are extracted from protocol-specific TVL pipelines. On Solana, daily net changes are similarly extracted from protocol-specific instruction pipelines. These changes are derived from the net result of deposits, withdrawals, mints, burns, and other balance-altering actions within each venue. The extracted records are grouped by timestamp, protocol, chain, product, token symbol, and token address.
- **Key fields**: `timestamp` (date of the record) `amount` (daily net change in asset quantity) `token_address` (onchain address of the asset) `product` (specific product or pool within the protocol) `protocol` (identifier of the protocol)

### Component B: Calculate cumulative TVL and fill missing days

- **Purpose**: Compute the running balance of each asset and ensure continuous daily coverage.
- **Logic**: The daily net changes are aggregated chronologically using a cumulative sum partitioned by protocol, chain, product, and asset to determine the total balance of the asset held in each venue over time. For days where no balance-altering events are recorded, the last known cumulative balance is carried forward to ensure a continuous daily time series.
- **Key fields**: `timestamp` (date of the record) `tvl` (cumulative asset balance)

### Component C: Map assets and convert to USD

- **Purpose**: Map token addresses to unique asset identifiers and convert the cumulative balances to USD.
- **Logic**: Token addresses are mapped to unique asset identifiers using a deduplicated asset registry to prevent data duplication. The cumulative asset quantities are normalized by decimal precision retrieved from asset metadata. The normalized balances are then multiplied by end-of-day price feeds to calculate the final USD value.
- **Key fields**: `timestamp` (date of the record) `tvl` (final cumulative asset balance in USD) `price_usd` (end-of-day price of the asset)

Tokenized stocks

The platform operates through a comprehensive infrastructure that includes Chainlink oracles for verified price data, Chainlink Proof of Reserve for transparent collateral verification, and Chainlink CCIP for cross-chain bridging capabilities. xStocks provides both retail products through partnerships with major exchanges like Kraken and Bybit, and institutional tokenization services that allow funds and financial institutions to create custom tokenized investment products within weeks. The business model encompasses both direct token issuance and a turnkey tokenization platform for enterprise clients seeking to digitize their investment strategies and fund structures.

xStocks creates tokenized representations of real-world assets (RWAs) including stocks and ETFs as ERC-20 tokens called xStocks that are fully composable with DeFi protocols. Each token is backed 1:1 by the underlying asset held by licensed third-party custodians, allowing users to gain exposure to traditional financial markets within the decentralized finance ecosystem. The platform offers multichain support and enables users to bridge assets across different blockchains while maintaining full redeemability for the underlying asset's cash value.

xStocks is a Swiss-based fintech company that specializes in bringing traditional financial assets onto blockchain infrastructure through tokenization. The company operates under a compliant regulatory framework based on the Swiss DLT Act to provide institutional-grade tokenized securities.
