BKL-1, issued by Reental, is a tokenized real-estate investment that fractionalizes a single property vehicle onchain and tracks the value and rental performance of - BACALAR 1 [S1][S2].

The reference asset is - BACALAR 1 (BKL-1), and each token represents a proportional claim on that property held by its per-project vehicle [S1][S3]. This is a total-return instrument: tokenholders receive rental income distributed monthly in USDT, a stablecoin, in proportion to their holding, and may claim or reinvest distributions to compound [S1][S3][S2]. At the end of the property's cycle, holders recover their initial investment plus a share of any capital gain on sale; a 19% withholding applies in Spain [S4].

Reental operates from Spain and the United States, forming a dedicated per-project vehicle for each issuance rather than a single named parent issuer [S5][S1]. U.S. projects are private placements under the Securities Act of 1933, using Regulation D Rule 506(c) and Regulation S; Spanish projects are issued under Law 6/2023 on Securities Markets and Investment Services [S5][S2]. The token represents tokenized LLC shares in the United States, or a beneficiary interest in a participatory loan in Spain [S1][S5]. Investors complete KYC and AML checks, and U.S. tax residents must be accredited [S5][S4]. There is no issuer buyback; tokenholders sell to validated buyers [S6].

The property tokens are issued natively on the Polygon network and held in the investor's own offchain self-custodied wallet, such as MetaMask, Rabby, or HumanWallet [S5][S6]. To invest, a user registers, completes KYC and AML validation, purchases tokens with USDT or by bank transfer at a one-token minimum, and signs the investment agreement [S1][S5]. Distributions settle in USDT to the tokenholder's wallet [S1][S2].

# 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)
