CARTAOSB62, issued by MB Securitização e Distribuição S.A., is a tokenized-fund instrument that represents a fractional interest in Cartao Sub 62 and tracks its net asset value [S1][S2].

The token references Cartao Sub 62 (CARTAOSB62) as a certificate of receivables backed by credit rights under Brazil's Renda Fixa Digital line [S2][S1]. Returns follow either a pre-fixed or post-fixed model tied to indicators such as IPCA inflation, are paid in Brazilian reais, and accrue as total return at maturity rather than perpetual price tracking [S3][S4]. Trading carries no platform, custody, or maintenance fees; any product-specific fees appear in each token's lâmina [S5][S3].

The distribution and securitization issuer is MB Securitização e Distribuição S.A., operating through a crowdfunding platform under Resolução CVM nº 88 with registration exemption in Brazil, regulated by the Comissão de Valores Mobiliários [S1][S6]. The platform operator is Mercado Bitcoin Serviços Digitais Ltda. [S7]. Holders own certificates of receivables representing securitization titles backed by credit rights [S2][S1]. Investors open a free account, complete KYC identity verification, and invest from R$ 100 [S5]. Redemption occurs through liquidação of the underlying at maturity, paying reais proportional to tokens held, with secondary-market resale available between users [S4][S8]. Client deposits sit in segregated institutional custody audited annually by KPMG [S5].

Tokens are issued on the Rootstock, Polygon and Ethereum networks using the ERC-20 standard, with each offering's network confirmed in its lâmina [S9][S3][S2]. They are distributed through MB Securitizadora's crowdfunding platform with offering documents including the Anexo E and Termo de Securitização [S1][S2]. Settlement pays reais into the holder's account at maturity or as a partial advance, reducing tokens proportionally, and balances are verifiable on a public onchain registry [S4][S8].

# Asset transfer count methodology

## 1. Overview

Asset transfer count is defined as the number of user transactions that move assets between addresses. It is utilized to reflect how frequently assets are used for payments, trading, or other onchain activity. The metric is calculated daily for each tracked asset across all supported blockchains. By aggregating these transfer events, a comprehensive view of onchain utility and transactional velocity is provided.

## 2. Data sources

- **EVM chain events**: ERC-20 token transfers, covering EVM-compatible chains (Ethereum, Arbitrum, Base, Polygon, Optimism, and others)
- **Solana instructions**: SPL token transfers
- **Other blockchain events**: Token transfers, withdrawals, and mint events across non-EVM chains (Solana, Aptos, Near, Polkadot Asset Hub, Stellar, and others)
- **Asset metadata**: Token addresses and decimal precision

## 3. Step-by-step calculation

### Component A: Extract and count raw transfer events

- **Purpose**: Identify and count individual token transfer events on a daily basis for each asset.
- **Logic**: On EVM-compatible chains, ERC-20 token transfers are parsed and counted. On Solana, SPL token transfers are parsed and counted. On Aptos, Near, and Ripple, token transfers and withdrawals are parsed and counted. On Stellar, classic token withdrawals and Soroban token transfers are aggregated. On Sui, token withdrawals and token mint events are aggregated. On Cardano, UTXO withdrawals and token mint events are aggregated. On Polkadot Asset Hub, `Transferred` events from the `assets` pallet are parsed.
- **Key fields**: `token_address`: The unique identifier of the token contract or asset. `block_timestamp`: The timestamp of the transaction block.

### Component B: Daily aggregation and zero-filling

- **Purpose**: Aggregate the daily transfer counts per asset and ensure continuous time-series data.
- **Logic**: The extracted transfer counts are aggregated daily for each token address on its respective chain. For days where no transfer activity is recorded for a tracked asset, the time series is filled with zero values to ensure a continuous daily record.
- **Key fields**: `timestamp`: The day of the activity. `asset_transfer_count`: The daily count of transfers per token on a specific chain.

### Component C: Final aggregation

- **Purpose**: Combine the daily transfer counts across all supported chains for each asset.
- **Logic**: The daily transfer counts from all individual chains are combined. Token addresses are mapped to unique asset identifiers using asset metadata. The final daily asset transfer count is then aggregated across all chains for each asset.
- **Key fields**: `timestamp`: The day of the activity. `asset_transfer_count`: The total aggregated daily transfer count for the asset.
