Spark Liquidity Layer AUM

Overview

amount of assets under management by the Spark Liquidity Layer.

Data sources

• ERC-20 Transfer events from multiple blockchains including Ethereum, Arbitrum, and Base
• Lending-specific events such as Mint, Burn, and BalanceTransfer
• End-of-day token price feeds for USD conversion
• Asset metadata and liquidity index data for balance normalization

Common calculation approaches

Token balance tracking

Regular token holdings are tracked through ERC-20 Transfer events associated with Spark Liquidity accounts. These movements are aggregated across supported chains to maintain a record of circulating assets held within the liquidity layer.

Lending position valuation

Lending protocol positions are derived from events such as Mint, Burn, and BalanceTransfer from protocols including Aave V3 and SparkLend. These balances are adjusted by applying liquidity indices from ReserveDataUpdated events to ensure accrued interest is reflected in the total value.

Managed asset aggregation

Total assets are calculated by combining regular token balances with specialized positions, such as cooldown balances from Ethena. All held assets are normalized by decimal precision and converted to USD values, while specific protocol-native tokens are excluded from the final aggregation.

Note: The calculation approaches and protocol examples above are representative patterns. Individual protocol implementations may vary.
