DIA-L-COL1, issued by Ctrl Alt Solutions FZCO, is a tokenized commodity instrument that gives institutional holders allocated exposure to Diamonds: L Collection 1, with certified physical holdings structured through a dedicated legal vehicle. [S1][S2]

DIA-L-COL1 represents an allocated interest in Diamonds: L Collection 1 (DIA-L-COL1), a physical commodity held through a separate legal entity in which investors are shareholders rather than held by the issuer. [S2][S3] The holding is asset-backed and not income-generating, so no dividend, distribution, or yield accrual applies. [S1][S4] Holders bear fees disclosed on the platform and detailed in trade confirmations, which may include transfer, registration, exchange, and settlement charges plus applicable tax. [S5]

Ctrl Alt Solutions FZCO, registered in Dubai DMCC and licensed by the Virtual Assets Regulatory Authority for Broker Dealer and Issuer Services, structures each asset through a dedicated vehicle such as an SPV, fund, or protected cell company. [S4][S2][S3] Investors hold shares in that separate entity, so the underlying assets are segregated from the issuer and Ctrl Alt has no claim to them. [S2] Access is restricted to professional clients, eligible counterparties, and institutional investors. [S2][S4] No guaranteed redemption mechanism applies, and holders may be required to hold for an indefinite period. [S5] Digital-asset custody is provided through Ripple institutional-grade custody technology. [S1][S6]

Tokens in this class are issued onchain on the XRP Ledger operated by Ripple. [S1][S6] Ctrl Alt provides the technology to mint the issuance, run compliance and KYC and AML checks, and perform real-time cap-table management. [S7][S3] Settlement occurs through onchain transactions and smart contracts enabling digital issuance, transfer, and immediate settlement while preserving traditional oversight. [S3][S8]

# Asset senders (weekly) methodology

## 1. Overview

`Asset senders (weekly)` is defined as the number of unique addresses that initiate asset transfers over a rolling 7-day period. For each tracked asset, outgoing transactions are analyzed to identify the addresses responsible for moving tokens. This metric is utilized as a key indicator of weekly user activity and transactional engagement for tokenized assets across various blockchain networks. By aggregating unique sending addresses within a moving 7-day window, short-term fluctuations are smoothed out to provide a clearer view of active adoption.

## 2. Data sources

- **EVM chain events**: ERC-20 token transfers, covering EVM-compatible chains (Ethereum, Arbitrum, Base, Polygon, Optimism, and others)
- **Solana instructions**: Token transfer instructions
- **Other blockchain data**: Token transfer and withdrawal events from Aptos, Near, Polkadot Asset Hub, Stellar, Sui, Ripple, and others
- **Asset metadata**: Token contract addresses and asset mapping datasets

## 3. Step-by-step calculation

### Component A: Extraction of daily sending addresses

- **Purpose**: Identify and extract unique addresses initiating token transfers on a daily basis for each asset.
- **Logic**: On EVM-compatible chains, sending addresses are extracted from ERC-20 token transfers where the sender address is not the null address. On Solana, sending addresses are identified from token transfer instructions using the authority address. On Aptos, Sui, Cardano, and Stellar Classic, sending addresses are retrieved from token withdrawal events. On Stellar Soroban, transfers are parsed from Soroban token transfer events, excluding mint transactions where the sender address is null. On Polkadot Asset Hub, `Transferred` events from the `assets` pallet are parsed to identify the sender. On Ripple, outgoing transfers are identified where the transaction value is negative. On Near and Injective, sending addresses are extracted from token transfer events where the sender address is populated.
- **Key fields**: `timestamp` (block time truncated to the day), `token_address` (the contract or asset identifier), `sender_address` (the address initiating the transfer)

### Component B: Rolling 7-day window aggregation

- **Purpose**: Aggregate daily active senders into a rolling 7-day window to calculate weekly activity.
- **Logic**: A daily datespine is generated to establish a continuous timeline. For each day in the timeline, a rolling 7-day window is constructed by looking back at the preceding six days. Daily unique sending addresses are mapped to each active window based on their transaction timestamps.
- **Key fields**: `timestamp` (the reference day for the rolling window), `token_address` (the asset identifier), `sender_address` (the address active within the window)

### Component C: Final deduplication and aggregation

- **Purpose**: Calculate the final weekly unique sender count per asset and chain.
- **Logic**: Within each rolling 7-day window, sending addresses are deduplicated to ensure each unique address is counted only once per asset, regardless of transaction frequency. The deduplicated counts are aggregated at both the individual chain level and the global asset level. Missing dates are filled with zero values to maintain a continuous time series.
- **Key fields**: `timestamp` (the reference day), `chain_id` (the blockchain identifier), `token_address` (the asset contract address), `asset_senders_weekly` (the count of unique weekly sending addresses)
