DCP, issued by Great Bridge Capital Company and tokenized by Zeconomy, an institutional digital assets platform built on the Zeno Protocol, is tokenized Digital Commercial Paper representing a short-term debt instrument administered by Guggenheim Treasury Services. [S1]

DCP holders receive economic exposure to Digital Commercial Paper backed by maturity-matched U.S. Treasury securities, with custom maturities of up to 397 days. The instrument carries a Prime-1 short-term rating from Moody's. Return accrues over the term of each note through the maturity-matched U.S. Treasury backing, with principal and accrued amount payable to the holder at the note's maturity. Issuance and administration are conducted through the Zeconomy platform and Guggenheim Treasury Services respectively. [S1]

Great Bridge Capital Company serves as the issuing entity, structured as a bankruptcy-remote special purpose vehicle so that the program assets are isolated for the benefit of noteholders. The underlying U.S. Treasury securities backing the instrument are custodied at U.S. Bancorp. Guggenheim Treasury Services administers the program, and Zeconomy manages issuance through its platform. The instrument is structured as institutional Digital Commercial Paper, a short-term debt claim rated Prime-1 by Moody's. Backing is maturity-matched to the Treasury securities held in custody for the program. [S1]

DCP is issued natively as a token on the XRP Ledger. Each note tracks a maturity-matched portfolio of U.S. Treasury securities, with custom maturities configurable up to 397 days. The token is settled and held onchain through the Zeconomy platform, with backing administered by Guggenheim Treasury Services and custodied at U.S. Bancorp. [S1]

# Asset transfer volume methodology

## 1. Overview

Asset transfer volume is defined as the total value of assets transferred onchain. Since transaction fees are paid by users for each transfer, a correlation is typically observed between this metric and the customer demand that exists to use an asset for transacting purposes. Daily transfer volumes are aggregated across all supported blockchains, normalized by decimal precision, and converted into USD. To ensure an accurate representation of economic activity, transactions involving non-circulating treasury or premint addresses are subtracted where applicable.

## 2. Data sources

- **EVM chain events**: ERC-20 token transfers, covering EVM-compatible chains (Ethereum, Arbitrum, Base, Polygon, Optimism, Tron, Starknet, zkSync Era, and others)
- **Solana instructions**: SPL token transfers, mints, and burns
- **Aptos events**: Token withdraw events
- **Near events**: Token transfer events
- **Polkadot Asset Hub events**: `Transferred` events from the `assets` pallet
- **Cardano UTXO transactions**: Token deposits, withdrawals, and mint/burn events
- **Stellar operations**: Classic token withdrawals and Soroban SEP-41 token transfers
- **Sui transactions**: Token withdrawals and `TreasuryCap` supply changes
- **Algorand transactions**: Asset transfer transactions
- **Injective events**: Token transfer, mint, and burn events
- **Stacks transactions**: Token transfer events
- **Asset metadata**: Token contract addresses and decimal precision
- **External data**: End-of-day price feeds and fiat exchange rates

## 3. Step-by-step calculation

### Component A: Raw transfer volume extraction

- **Purpose**: Extract raw token transfer quantities from onchain events and transactions
- **Logic**: On EVM-compatible chains, token transfer quantities are extracted from ERC-20 `Transfer` events. On Solana, quantities are extracted from SPL token transfers, mints, and burns. On Aptos, Near, Algorand, Injective, and Stacks, transfer volumes are parsed from native token transfer and withdrawal events. On Polkadot Asset Hub, volumes are extracted from `Transferred` events emitted by the `assets` pallet. On Cardano, UTXO withdrawals and mint events are aggregated to capture all token movements. On Stellar, classic token withdrawals and Soroban SEP-41 transfer, mint, and burn events are parsed. On Sui, token withdrawals are combined with mint events derived from `TreasuryCap` supply changes.
- **Key fields**: `timestamp` (the day of the transfer) `token_address` (the contract or asset identifier) `amount` (the raw transfer quantity)

### Component B: Premint and preburn correction

- **Purpose**: Exclude non-circulating token movements to isolate genuine economic transfer volume
- **Logic**: For supported chains, raw transfer volumes are corrected by subtracting premints and preburns. Premints are defined as tokens minted directly into designated project treasury or premint addresses, while preburns are represented by tokens burned directly from these non-circulating addresses. On EVM-compatible chains, Solana, Injective, Stacks, and Stellar Soroban, these flows are identified by filtering transfers where the sender or recipient matches a known treasury address. On Algorand, transfers between asset configuration addresses and treasury addresses are subtracted. On Cardano, deposits to and withdrawals from treasury addresses during mint or burn transactions are netted out.
- **Key fields**: `amount` (the corrected transfer quantity) `token_address` (the contract or asset identifier) `timestamp` (the day of the transfer)

### Component C: Decimal normalization and zero-filling

- **Purpose**: Normalize token quantities to human-readable units and ensure continuous daily time series
- **Logic**: Raw token quantities are normalized by the decimal precision retrieved from the asset metadata. For days with no recorded transfer activity, the time series is filled with zero values to maintain a continuous daily record for each asset.
- **Key fields**: `amount` (the normalized transfer quantity) `decimals` (the decimal precision of the token)

### Component D: USD conversion and final aggregation

- **Purpose**: Convert normalized transfer volumes to USD and aggregate across all chains
- **Logic**: Normalized daily transfer volumes are multiplied by the end-of-day price feeds sourced from market data providers. For assets pegged to fiat currencies other than USD, daily exchange rates are applied using Chainlink FX price feeds to determine the USD-equivalent value. The final daily asset transfer volume is calculated by summing the USD-denominated transfer volumes across all active chains for each asset.
- **Key fields**: `price_usd` (the end-of-day market price of the asset in USD) `amount_usd` (the final transfer volume in USD)

Tokenized funds

Zeconomy's platform handles smart-contract issuance, lifecycle management, and compliance for tokenized fixed-income instruments. Revenue is generated through tokenization and management fees on institutional issuances. Bankruptcy-remote SPVs (e.g., Great Bridge Capital Company for DCP) are used for investor protection.

Zeconomy operates the AmpFi.Digital platform, which issues asset-backed and rated digital instruments — including Digital Commercial Paper (DCP) administered by Guggenheim Treasury Services and natively deployed on the XRP Ledger. DCP is Moody's Prime-1 rated, backed by maturity-matched U.S. Treasury securities, with custom maturities up to 397 days.

Zeconomy is an institutional digital assets platform that issues, tokenizes, and manages real-world assets on public blockchains, with a focus on enabling traditional financial institutions to bring fixed-income and other instruments on-chain.
