mBTC, issued by Midas Software GmbH, is a tokenized fund that gives investors onchain exposure to mBTC, expressed as a NAV per token that moves with the underlying portfolio's performance [S1].

The token tracks mBTC (mBTC) on a total-return basis, accruing value through changes in NAV rather than any peg or floor [S1]. Holders bear a management fee as a percentage of NAV and a performance fee on profits above a high-water mark, and instant redemption carries a fixed fee typically between twenty and one hundred basis points [S2].

Midas Software GmbH, a Berlin company incorporated under German law, issues each token as a Blockchain-based Certificate, a MiFID II debt instrument under a base prospectus approved by the Liechtenstein Financial Market Authority; the issuer is not itself licensed or regulated and approval is not an endorsement [S3][S4][S5]. Tokenholders hold a contractual claim against the issuer, not ownership of the underlying assets [S3]. Tokens are not offered to U.S. Persons, sanctioned parties, or restricted jurisdictions, and access requires KYC and AML verification, with some strategies limited to professional investors [S6]. Standard redemption settles after the next NAV update and instant redemption burns tokens for a stablecoin [S7].

The tokens are ERC-20 tokens issued natively across BNB Chain, Ethereum, Monad, Base, an Ethereum Layer 2, Plasma, Starknet, Katana Network, OP Mainnet, and Rootstock [S8][S9]. Deposits mint at current NAV instantly or at the next settlement [S7]. NAV equals total portfolio value divided by tokens outstanding and is published onchain through an Oracle Feed using Chainlink and Pyth [S1].

# 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)
