DFX (CoinDesk DeFi Select Index), issued onchain through the Reserve protocol whose interface is operated by ABC Labs, LLC, is a Decentralized Token Folio (DTF) that wraps the constituents of the CoinDesk DeFi Select Index into a single fungible ERC-20 index token whose value tracks its underlying holdings [S1][S2].

Each token represents a pro-rata onchain claim on the DTF's underlying ERC-20 basket, and holders can mint or redeem permissionlessly at real-time net asset value (NAV) without authorized participants or intermediaries [S1]. The basket is periodically rebalanced toward governance-set target weights through onchain Dutch auctions priced on an exponential decay curve [S3]. Two fees are borne by holders and accrue in the DTF token itself: a TVL fee assessed block-by-block and capped at 10% annualized, and a mint fee charged on issuance [S4].

The Reserve protocol smart contracts and the reserve.org and app.reserve.org interfaces are operated by ABC Labs, LLC under the laws of the State of Delaware [S2]. ABC Labs states it is not a bank, broker-dealer, investment adviser, commodity trading adviser, or other regulated financial intermediary, and is not registered with the U.S. Securities and Exchange Commission, the Commodity Futures Trading Commission, or any other financial authority [S2]. All DTFs are permissionlessly created by third parties unaffiliated with ABC Labs, which does not control them; DTFs are not deposits and are not insured by the FDIC or SIPC, and access is restricted for OFAC-sanctioned persons and jurisdictions [S2].

DFX follows the ERC-20 standard, with basket assets held on the same blockchain as the DTF, and is deployed on Ethereum [S1]. Anyone can mint or redeem permissionlessly at NAV against the underlying tokens, with zapper helpers enabling single-token entry and exit [S1]. Governance escrows a vote-locking token in a staking vault and gates basket changes through a governor operating under a default 48-hour timelock with Guardian veto rights [S5].

# Asset Price methodology

## 1. Overview

Asset price represents the closing USD value of a tokenized asset at the end of each day. Daily prices are recorded to facilitate the valuation of on-chain activity and the calculation of market capitalization. Each price point reflects the market value at the conclusion of the UTC day.

## 2. Data sources

- **Asset metadata**: Token contract addresses, ticker identifiers, and on-chain launch timestamps
- **External data**: End-of-day price feeds and exchange rate feeds from market data providers
- **Blockchain data**: Data covering EVM-compatible chains (Ethereum, Arbitrum, Base, Polygon, Optimism, and others) and non-EVM chains such as Solana, Aptos, and Near

## 3. Step-by-step calculation

### Component A: Market data retrieval

- **Purpose**: Collect raw daily price information
- **Logic**: Daily price data is retrieved from external market data providers. For assets pegged to specific currencies, prices are calculated using a multiplier and daily exchange rates. For assets traded on traditional exchanges where data is unavailable on certain days, such as weekends or holidays, missing values are filled with the last available closing price.

### Component B: Timestamp normalization

- **Purpose**: Align price data with daily reporting periods
- **Logic**: Timestamps are truncated to the daily grain. To accurately reflect the closing value, prices recorded at the start of a day (00:00:00 UTC) are assigned to the preceding calendar day.

### Component C: Asset mapping and deduplication

- **Purpose**: Associate prices with unique assets and resolve data overlaps
- **Logic**: Prices are mapped to assets using unique identifiers for EVM-compatible and non-EVM chains. To ensure data integrity, price records are filtered to include only those occurring on or after the asset's on-chain launch date. In instances where price data for a single asset is available from multiple sources, the data is deduplicated by selecting the record with the highest priority to ensure a single, consistent closing price.
