XAUM, issued by Prometheus Solutions Ltd, is a digital token representing allocated physical gold that grants each holder a claim on one fine troy ounce of high-grade 99.99%-purity LBMA-accredited bullion held in vaults [S1][S2].

Each XAUM token tracks the value of physical Gold, with total token supply backed 1:1 by LBMA-accredited 99.99%-purity bars whose weight equals the gold held in vaults [S1][S2]. The token is price-tracking and accrues no native yield, with value following the underlying metal [S1]. Holders bear a management fee that is waived until $100M total value locked and a redemption fee of 0.25% [S1].

Prometheus Solutions Ltd operates the Matrixdock brand, with an AML statement referencing British Virgin Islands (BVI) sanctions lists consistent with a BVI nexus [S3]. Each token is issued through a dedicated bankruptcy-remote special purpose vehicle (SPV) held under a purpose trust, segregating reserve gold from Matrixdock's balance sheet, with the gold SPV mutually segregated from other product SPVs [S4]. Secondary holding and transfer are permissionless, while primary minting and redemption require KYC onboarding [S1]. Holders may redeem for USD Coin (USDC), USD fiat, or physical gold, with a minimum mint of $10,000 and minimum redemption of 32.148 XAUM, equal to one 1kg bar [S1].

XAUM uses fungible ERC-20 and BEP-20 standards alongside ERC-721 and BEP-721 NFT forms representing specific bars, deployed on chains including Ethereum, BNB Chain, Solana, Sui, HashKey, and Plume [S1]. Token supply tracks vaulted gold, reserves are verified by Bureau Veritas physical audits and onchain Proof of Reserves feeds, and dynamic allocation reallocates bars in real time [S1][S2][S5].

# Asset senders (monthly) methodology

## 1. Overview

Asset senders (monthly) is defined as the number of unique addresses from which asset transfers are initiated over a rolling 30-day period. For each tracked asset, outgoing transfer transactions are analyzed across supported blockchains to identify the sending addresses. These addresses are deduplicated over a 30-day window to represent the monthly active sender base. This metric is utilized to evaluate user adoption, transactional activity, and the overall utility of tokenized assets.

## 2. Data sources

- **EVM chain events**: Token transfer events, covering EVM-compatible chains (Ethereum, Arbitrum, Base, Polygon, Optimism, and others)
- **Solana instructions**: Token transfer instructions
- **Aptos, Sui, Cardano, and Stellar Classic data**: Token withdraw transactions
- **Stellar Soroban, Algorand, Near, Injective, and Ripple data**: Token transfer transactions
- **Polkadot Asset Hub events**: `Transferred` events from `assets` pallets
- **Asset metadata**: Token contract addresses and decimal precision

## 3. Step-by-step calculation

### Component A: Extract daily asset senders

- **Purpose**: Identify unique addresses initiating transfers on a daily basis
- **Logic**: On EVM-compatible chains, token transfer events are parsed to extract the sender address from the transaction, excluding the zero address. On Solana, token transfer instructions are parsed to identify the authority address. On Aptos, Sui, Cardano, and Stellar Classic, token withdraw transactions are parsed to extract the account address. On Stellar Soroban, Algorand, Near, and Injective, token transfer transactions are parsed to extract the sender address, excluding null addresses. On Ripple, token transfer transactions with negative values are parsed to identify the sending account address. On Polkadot Asset Hub, `Transferred` events from `assets` pallets are parsed to extract the sender address. For all chains, the extracted addresses are grouped by day and token address to produce a daily record of unique senders.
- **Key fields**: `timestamp` (block day), `token_address` (asset identifier), `sender_address` (initiating address)

### Component B: Aggregate rolling monthly senders

- **Purpose**: Calculate the unique sender count over a rolling 30-day window
- **Logic**: A daily datespine is generated to establish a continuous timeline. For each day in the timeline, a 30-day lookback window is constructed, encompassing the current day and the preceding 29 days. Daily sender addresses collected within this window are aggregated and deduplicated. The total number of unique, deduplicated addresses is then counted for each asset on each day.
- **Key fields**: `timestamp` (calculation day), `token_address` (asset identifier), `asset_senders` (unique monthly sender count)

### Component C: Final aggregation and zero-filling

- **Purpose**: Combine data across chains and fill missing activity days
- **Logic**: The deduplicated monthly sender counts are aggregated at both the individual chain level and the global asset level. For days where no transfer activity is recorded for a tracked asset, the metric is filled with zero values to maintain a continuous time series.
- **Key fields**: `timestamp` (reporting day), `chain_id` (blockchain identifier), `token_address` (asset identifier), `asset_senders` (final monthly unique sender count)

Real-world asset (RWA) issuers

Matrixdock

Matrixdock Gold (XAUM) is a gold-backed token issued by Matrixdock.

Each token represents one troy ounce of gold and is a direct claim on the issuer.

The metal is held in vaults in Singapore and Hong Kong operated by Brink's and Malca-Amit on a segregated, bankruptcy-remote basis and is attested by Bureau Veritas.

Holders can mint and redeem directly with Matrixdock after completing KYC, and holders have a contractual right to redeem for physical delivery of the metal or its cash value, with same- or next-business-day settlement.

XAUM has been issued on public blockchains since September 2024 and is native to 9 networks, including BNB Chain, Ethereum, Tron, Sui, Polygon, and Solana.
