BGCI (Bloomberg Galaxy Crypto 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 Bloomberg Galaxy Crypto 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].

BGCI follows the ERC-20 standard, with basket assets held on the same blockchain as the DTF, and is deployed on Base [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].

# Circulating asset market cap methodology

## 1. Overview

Circulating asset market cap measures the total value that has been tokenized onchain for a specific asset. It is calculated by multiplying the circulating supply of the asset by its end-of-day market price. For stablecoins, this metric represents the total outstanding supply; for tokenized funds, it reflects the onchain assets under management (AUM); and for tokenized stocks, it measures the total supply of shares issued onchain.

## 2. Data sources

- **EVM chain events**: ERC-20 `Transfer` events, covering Ethereum, Arbitrum, Base, Polygon, Optimism, and others
- **Solana instructions**: SPL token `Mint` and `Burn` instructions
- **Other blockchain data**: Issuance and redemption events from Aptos, Near, Polkadot Asset Hub, and Stellar
- **Asset metadata**: Token addresses and decimal precision
- **External data**: End-of-day price feeds

## 3. Step-by-step calculation

### Component A: Identification of supply changes

- **Purpose**: Identify all onchain events that increase or decrease the total supply of an asset
- **Logic**: On EVM-compatible chains, ERC-20 `Transfer` events are parsed to identify mints (where the sender is the zero address) and burns (where the recipient is the zero address). On Solana, SPL token `Mint` and `Burn` instructions are retrieved. On other chains, such as Aptos or Polkadot Asset Hub, equivalent issuance and destruction events are identified from the respective asset programs or pallets.
- **Key fields**: `amount` (quantity of tokens), `token_address` (unique asset identifier), `timestamp` (time of the event)

### Component B: Normalization and daily supply aggregation

- **Purpose**: Convert raw event data into a continuous daily circulating supply time series
- **Logic**: Raw token amounts are normalized by decimal precision retrieved from asset metadata. The daily circulating supply is determined by calculating the cumulative sum of all identified mint and burn events for each asset. For days where no onchain activity occurs, the supply value is filled with the last known value to ensure a continuous daily record.
- **Key fields**: `amount` (normalized quantity), `timestamp` (truncated to daily grain)

### Component C: Final market cap calculation

- **Purpose**: Combine supply data with market prices to determine the total USD value
- **Logic**: The daily circulating supply is multiplied by the end-of-day market price sourced from market data providers. Data is aggregated across all supported chains to provide a comprehensive view of the asset's onchain presence. The final USD conversion is applied: `amount_usd = amount × price_usd`.
- **Key fields**: `price_usd` (end-of-day market price), `amount_usd` (final circulating market cap)
